This blog will explore functional block diagrams, their pivotal role in system design, the symbiotic relationship with ladder logic, structured text, and the broader realm of PLC programming. Why FBDs are so important within complex systems.
A functional block diagram is a schematic representation that delineates the principal functions of a system and the flow of data between them. It serves as a cornerstone in system engineering, simplifying the visualization of complex interactions within systems. FBDs are characterized by their use of labeled blocks connected by lines indicating dataflow, making them an intuitive means for depicting system operations.
The advantages of function block diagrams are that they’re very easy to follow and understand. They are generally laid out to mimic a specific process thus making it easy to understand for those who don’t have a background in plc programming.
In essence, an FBD breaks down large systems into manageable, functionally discrete blocks, facilitating a modular approach to system design. This modularity is crucial, allowing designers to focus on individual functions without being overwhelmed by the system's overall complexity.
The potency of a functional block diagram lies in its simplicity and clarity, achieved through three fundamental components:
FBDs do not exist in isolation; they are part of a larger ecosystem of programming languages and representation techniques used in the programming of programmable logic controllers (PLCs). Ladder logic, with its origins in electrical wiring diagrams, offers a graphical method that is intuitive for those with a background in electrical engineering. It depicts control logic in a format resembling a ladder, with rungs representing logical operations.
Structured text, another facet of PLC programming, is a high-level textual programming language that resembles traditional computer programming languages. It allows for complex instructions and algorithms to be implemented in a more familiar syntactic form.
FBDs complement these programming paradigms by providing a visual overview of system logic and dataflow, serving as a bridge between the conceptual design and the detailed implementation in ladder logic or structured text. This synergy enhances the understandability, development efficiency, and maintainability of PLC-based systems.
PLCs stand at the forefront of industrial automation, controlling machinery and processes with precision and reliability. In the domain of PLC programming, FBDs play a pivotal role, offering a graphical method for designing and implementing control logic.
FBDs align perfectly with the operational paradigm of PLCs, which are inherently designed to execute logic operations based on real-time data inputs. The visual nature of FBDs facilitates the rapid development and troubleshooting of PLC programs, enabling engineers to map out complex control strategies in a more intuitive and less error-prone manner.
Moreover, the adoption of FBDs in PLC programming underscores the importance of a clear and structured approach to system design. By visualizing the functional architecture of a system, engineers can ensure that all components interact harmoniously, leading to more robust and reliable PLC-based control systems.
As system complexity continues to escalate, the role of functional block diagrams in system design is not only preserved but also expanding. The integration of FBDs with advanced simulation tools and software development environments is enhancing their utility, allowing for more dynamic and interactive system modeling.
The future of FBDs is likely to witness further integration with artificial intelligence and machine learning technologies, enabling smarter and more adaptive systems. As these advanced systems become more prevalent, the clarity and efficiency offered by FBDs will become even more critical in navigating the complexity of modern system design.
Functional block diagrams are a testament to the power of visual representation in the realm of system design. By distilling complex system functionalities into comprehensible blocks and illustrating the dataflow dynamics, FBDs provide a foundation for designing, implementing, and maintaining sophisticated systems. Their symbiotic relationship with ladder logic, structured text, and PLC programming languages enhances their utility, making them an indispensable tool in the engineer's toolkit.

This blog post explores the fundamental role of diodes in electronics, focusing on understanding their symbols and various types like Zener, Schottky, and LEDs. It details the electrical signal of diodes, illustrating how they allow current flow in one direction.
A diode, fundamentally a PN junction, permits current to flow primarily in one direction. It consists of two different doped semiconductor regions -- an N doped and a P dope region -- joined together, forming a PN junction.
Its electrical signal is characterized by allowing easy current flow in the forward direction, while significantly impeding it in the reverse. This unique property is visually represented by an arrow, pointing in the allowed direction of current flow, and a line indicating the barrier for reverse flow.
Identifying a diode in a circuit involves looking for a component with two terminals: the anode and the cathode. The anode is marked by the arrowhead in the diode symbol, pointing towards the cathode, marked by the vertical line. Physical diodes often have a band on the cathode side. In schematics, diodes are also marked with designators like ‘D’ followed by a number (e.g., D1, D2).
Diodes serve myriad purposes in electronics. Their primary function is to enable unidirectional current flow, making them crucial for tasks like rectification – converting alternating current (AC) to direct current (DC). Specific diode types, such as the Zener diode, offer voltage regulation by maintaining a constant voltage over a range of currents. Varactor diodes (varicaps) change capacitance based on the applied voltage, useful in tuning circuits. Meanwhile, Schottky diodes, known for their low forward voltage drop, excel in fast-switching applications.
The function of a diode is primarily to control the direction of current flow in a circuit. Besides this, diodes have specialized functions based on their type:
A rectifier's core purpose is to convert AC to DC. In electronic circuits, this is crucial for powering devices that require stable DC voltage. Rectifier diodes are specifically designed for this task, efficiently handling high currents and voltages. Rectifiers are essential in power supplies, battery charging systems, and are integral to the functioning of electronic devices ranging from smartphones to industrial machinery.
In an automotive alternator, the rectifier converts the AC generated by the alternator into DC to charge the battery and power the electrical system. It typically employs a set of diodes arranged in a bridge configuration. The alternator generates three-phase AC, which the diode bridge rectifies into a smoother DC output. This process is vital for maintaining the battery’s charge and ensuring a consistent power supply to the vehicle's electrical systems.
Understanding diode symbols and their functions is a critical aspect of electronics. From simple rectification tasks to complex frequency tuning, diodes play pivotal roles in various applications. Recognizing these symbols not only aids in circuit analysis but also enriches the understanding of how electronic components interact to perform diverse and sophisticated functions. Whether it's a Zener diode stabilizing voltage or a laser diode in an optical communication system, each diode type brings unique capabilities to the vast and intricate world of electronics.

A PCB, or Printed Circuit Board, is a mechanically designed structure that electrically connects and mechanically supports electronic components using conductive tracks, pads, and other features etched from copper layers laminated onto a non-conductive substrate.
PCBs play a pivotal role in the functionality of virtually all electronic devices. They provide a physical platform for mounting components and establish the necessary electrical interconnections, thus forming a system's electronic circuitry.
The purpose of this article is to demystify the process of PCB design, taking you through the essential steps from conception to completion, along with offering practical tips for success.
The basis of any printed circuit board design lies in the electronic circuit you aim to build. Thus, a firm grasp of circuit design principles, such as understanding how different components interact and basic electronic principles, is vital.
Before starting the design, it is crucial to define the design parameters. These could include the board's size and shape, the number of layers, the types of components used (through-hole or surface mount), the operating environment, power requirements, and more.
Based on the design parameters and functional requirements, the right components and board material (such as dielectric) must be selected. Components should be chosen based on electrical requirements, availability, cost, and space considerations, while board material should provide appropriate thermal and mechanical stability.
The first step in PCB design is creating a schematic diagram that represents the electrical connections between different components. It serves as a blueprint for the PCB layout.
Each component symbol is placed on the schematic, and interconnections are drawn using lines to represent electrical connections or nets. Different components like resistors, capacitors, transistors, inductors, and integrated circuits, will each have their own unique component symbol.
The completed schematic diagram is used to generate a netlist, which is a comprehensive report detailing every electrical connection in the design.
Before progressing, the schematic should be thoroughly checked for errors to prevent problems in later stages.
Once the schematic is verified, the netlist is imported into a PCB layout tool to start designing the physical layout of the circuit board.
The PCB's dimensions and layers are defined, and design rules (spacing, width, etc.) are set based on manufacturing capabilities and requirements. This includes the selection of dielectric and stack up.
The completed schematic diagram is used to generate a netlist, which is a comprehensive report detailing every electrical connection in the design.
Before progressing, the schematic should be thoroughly checked for errors to prevent problems in later stages.
Components like capacitors, resistors, inductors, transistors, and integrated circuits are strategically placed on the circuit board to optimize space, minimize trace lengths, and avoid interference.
Traces, which are the copper paths connecting components, are routed based on the netlist. Their width is set to accommodate the current they will carry.
Unused areas on the PCB can be filled with copper pour to improve electromagnetic compatibility. Design rules checks (DRC) are run to ensure the design meets manufacturing tolerances.
Once the layout is finalized, Gerber files, which are the manufacturing blueprints for the PCB, are generated along with other manufacturing specifications.
The design is thoroughly reviewed one final time, and all necessary documentation for manufacturing is prepared.
The Gerber files and other documentation are sent to the manufacturer, and after their review and possible corrections, the PCB is manufactured. The manufacturer may also assemble the board for you, where they solder the electronic components.
Keep designs as simple as possible. Complexity increases the chances of error and can lead to difficulties in troubleshooting and manufacturing.
Constantly keep the design parameters in mind during the design process. Parameters such as operating frequency, power requirements, and environmental conditions can significantly affect the design.
Always be aware of the orientation of components, especially polarized components like diodes and capacitors, to avoid assembly errors. Appropriate designators on the silkscreen can help here. This can also help the assembly house when they solder the electronic components to the board.
Maintain clear and open communication with your PCB manufacturer. They can provide valuable feedback about design for manufacturability (DFM) and help avoid costly errors.

You just have to look for a component in the community library, add it to the schematic editor, and wire the pins together; then if the system detects you're using a component that needs impedance control - flux.ai will take care of the rest for you. This saves valuable time and effort for designers, allowing them to focus on other critical aspects of their design.
When selecting PCB design software, it's essential to consider your specific design requirements, ease of use, available features, and compatibility with your preferred design methodologies. It's also worth exploring the software's reputation within the industry, the level of community support, and the availability of comprehensive documentation. Altium Designer, Eagle, KiCad, OrCAD, and Proteus are a few examples of PCB design software out there.
At the core of every successful PCB design is the schematic diagram, sometimes called schematic design. It serves as the blueprint, visually representing the electrical connections and components of the circuit board design. A schematic diagram consists of component symbols, net connections between symbols, and netlist. These nets will become the traces on the PCB. The schematic diagram also acts as a common language, facilitating collaboration between engineers, designers, and manufacturers.
A well-designed schematic diagram brings clarity and organization to the circuit, allowing for a comprehensive understanding of its functionality. It also plays a vital role in ensuring electrical integrity by identifying and addressing potential issues early on, reducing the need for costly modifications later.
The schematic diagram serves as a reference point during testing and troubleshooting, enabling engineers to trace the signal flow and pinpoint problem areas. By utilizing standardized symbols and specialized software tools, the design process becomes more efficient and accurate.
In PCB design, layer stackup refers to the arrangement and configuration of the various layers that make up the PCB. It plays a crucial role in determining the performance, functionality, and manufacturability of the final board.
The layer stackup defines the number and type of copper and dielectric layers, their order, and the materials used. It directly impacts important aspects such as signal integrity, power distribution, thermal management, and impedance control. Proper layer stackup design ensures optimal electrical performance, reduces interference, and facilitates efficient routing of traces.
To create an effective layer stackup, designers must consider factors such as the number and types of signal layers, power, and ground planes, and the placement of critical components. The choice of materials for each layer and their dielectric properties is also significant, as it affects impedance matching, signal propagation, and heat dissipation.
By providing predefined layer stackups, Flux simplifies the design process and ensures compatibility with specific PCB manufacturers. The stackups configured for JLCPCB, PCBway, and AISLER, are tailored to their fabrication capabilities, including considerations for board thickness, copper weight, and minimum feature sizes. This facilitates seamless integration between the PCB design and manufacturing processes, streamlining production and reducing potential issues.
When working with flux.ai, designers can leverage the predefined layer stackups to align their design with the requirements of trusted PCB manufacturers. This not only saves time and effort but also enhances the likelihood of successful manufacturing outcomes.
In PCB design, one crucial aspect that greatly impacts the overall performance and manufacturability of the board is component placement. The strategic arrangement of components on the PCB plays a vital role in ensuring optimal functionality, signal integrity, thermal management, and ease of manufacturing and assembly.
Effective component placement starts with careful consideration of the functional requirements and constraints of the design. It involves placing components in such a way that minimizes signal interference, reduces trace lengths, and facilitates efficient routing. Proper component placement can enhance signal integrity by minimizing noise, crosstalk, and electromagnetic interference.
Thermal management is another critical factor to consider during component placement. Components that generate significant heat, such as power amplifiers or microprocessors, should be strategically positioned to allow for effective heat dissipation. Placing heat-sensitive components away from high-temperature sources can prevent overheating and ensure the longevity and reliability of the board.
Manufacturability and assembly considerations also come into play during component placement. Components should be positioned in a manner that allows for easy access during assembly and soldering processes. Adequate clearance and spacing should be provided to accommodate the size and shape of the components, as well as any required test points or connectors.
Coordinating the placement of PCB components with mechanical design elements, such as enclosure dimensions and mounting points, ensures seamless integration between the PCB and the overall product design.
To aid in efficient component placement, most PCB design software provides features like automated placement assistance and 3D visualization. These tools assist in aligning components, optimizing routing, and verifying clearances. However, the human touch and expertise of the designer remain invaluable in making informed decisions based on the specific requirements and constraints of the design.
In the world of PCBs, one critical aspect that demands careful attention and expertise is PCB routing. PCB routing involves the intricate task of connecting components and traces on the board, enabling the smooth flow of signals while considering factors like signal integrity, noise reduction, and manufacturability.
The routing process requires a keen understanding of the design requirements, electrical characteristics, and spatial constraints. Designers must carefully plan the routing strategy, taking into account the complexity of the circuit, signal frequencies, and the importance of signal paths.
To achieve optimal routing, designers must consider signal integrity factors such as trace length matching, impedance control, and minimizing electromagnetic interference. Critical high-speed signals often require controlled impedance routing, differential pair routing, and proper shielding techniques to ensure reliable signal transmission and prevent signal degradation.
Proper power distribution and ground plane design are also essential in PCB routing. By providing a robust power delivery network and a well-designed ground plane, designers can minimize voltage drop, reduce noise coupling, and ensure a stable power supply to all components.
While routing, designers must also consider the physical constraints of the PCB, including component footprints, board size, and mechanical considerations. Components should be placed and routed in a way that facilitates ease of assembly, maintenance, and future modifications if necessary.
Efficient PCB routing involves finding the optimal path for each signal while minimizing crosstalk and maintaining appropriate spacing between traces. Designers may employ routing techniques such as differential pair routing, length tuning, via stitching, and layer stacking to achieve the desired electrical performance.
Determining the appropriate trace width and spacing involves finding a balance between accommodating the current-carrying capacity of the trace, controlling impedance, and ensuring proper insulation between adjacent traces. The trace width refers to the width of the copper conductive path on the PCB. It plays a crucial role in carrying the required current without causing excessive resistance or voltage drop. Selecting the appropriate trace width depends on factors such as the maximum current expected to flow through the trace, the desired temperature rise, and the copper thickness. PCB Designers often refer to standard trace width tables or employ online calculators to determine the optimal trace width for a given current requirement.
Spacing between traces is equally important. It refers to the distance maintained between adjacent traces to prevent unintended coupling, crosstalk, and electromagnetic interference (EMI). Maintaining proper spacing ensures signal integrity and reduces the chances of cross-coupling between adjacent traces.
To establish appropriate trace width and spacing, industry standards and design guidelines are often followed. These standards specify minimum trace widths, spacing requirements, and clearance distances based on factors like signal type, operating frequency, and environmental considerations. Adhering to these guidelines helps ensure compliance with safety regulations and industry best practices.
One vital aspect that demands attention is understanding the design specifications for pads and vias. These elements serve as crucial connection points for integrated circuits, components, traces, and signal paths on the board. Having a thorough grasp of their design specifications is essential for achieving reliable electrical connections, efficient signal routing, and successful manufacturing.
Pads, also known as landing pads or soldering pads, provide the interface between the component leads and the PCB. They play a significant role in ensuring proper soldering, mechanical stability, and electrical connectivity. The design specifications for pads include dimensions such as diameter, shape, and solder mask clearance. These specifications are determined based on the component's footprint, lead size, and manufacturing process requirements.
The shape and dimensions of the pad should match the component's lead style, such as through-hole, surface-mount, or fine-pitch components. Adequate pad size and shape are crucial for achieving reliable solder joints and ensuring mechanical strength. The solder mask clearance around the pad helps to prevent solder bridging or short circuits during assembly.
Vias, on the other hand, are conductive pathways that connect different layers of the PCB. They enable the transfer of signals, power, and ground between different parts of the circuit. The design specifications for vias include parameters such as diameter, aspect ratio, and annular ring size.
There are different types of vias in PCB; through-hole via, blind via, buried via, and micro via. Through-hole vias are more common. Read more about different types of PCB vias.
The diameter of a via determines its electrical and thermal characteristics. It should be appropriately sized to handle the required current and ensure low-resistance connections. The aspect ratio, defined as the ratio of the via's depth to its diameter, affects the manufacturability and reliability of the via. Adequate aspect ratios are necessary to ensure proper plating and maintain structural integrity during the fabrication process.
The annular ring, which refers to the copper pad surrounding the via, is essential for maintaining the electrical connection between the via and the pad or trace. Sufficient annular ring width is necessary to ensure reliable electrical connectivity and prevent potential shorts or open circuits.
Gerber files are a collection of ASCII-based data files that describe the various layers, copper traces, pads, holes, and other design elements of the PCB.
When the PCB design is complete and ready for manufacturing, the design files are converted into Gerber files. These files provide a detailed representation of each layer of the PCB, including the top and bottom copper layers, solder mask layers, silkscreen layers, and drill files.
Gerber files are typically generated by the PCB design software used to create the layout. Each layer of the PCB design is exported as a separate Gerber file, with a specific extension that identifies the layer. The most common Gerber file extensions include .GTL (Top Layer), .GBL (Bottom Layer), .GTS (Top Solder Mask), .GBS (Bottom Solder Mask), .GTO (Top Silkscreen), .GBO (Bottom Silkscreen), and . TXT (Drill Files).
These Gerber files act as a bridge between the PCB designer and the PCB manufacturer. They contain all the necessary information required for the fabrication process, such as the dimensions, copper traces, solder mask openings, component placement locations, and drill hole positions.
Once the Gerber files are created, they are typically bundled together and submitted to the PCB manufacturer for the manufacturing process. The manufacturer uses the Gerber files to generate the photolithographic films or digital equivalents that are used in the fabrication steps, including the creation of the copper layers, solder mask application, silkscreen printing, and drilling of holes.
The BOM specifies the quantity of each component required for the PCB assembly, enabling accurate procurement and inventory management. The reference designator assigns a unique identifier to each component on the PCB, facilitating proper placement and soldering during the assembly process.
Finding a reliable and suitable manufacturer ensures the successful fabrication of your PCB design.
Choosing the right PCB manufacturer involves considering several factors. Here are a few key points to keep in mind:

The following Arduino Uno schematic diagram can be opened and forked in Flux so that you can create your own custom layout! This allows you to modify the position of components while maintaining the same pinouts.
The Arduino Uno schematic consists of several components, including the microcontroller, voltage regulator, USB interface, and various other passive components. Let's take a closer look at each component and its function in the schematic.
The Arduino Uno schematic provides a comprehensive pinout that gives electrical engineers access to various peripheral interfaces, such as I2C, SPI, and PWM. To utilize these interfaces, electrical engineers must first set the appropriate pinmode using the pinmode function. This function specifies whether a pin is set to input or output, which determines its behavior. The pinout of the Arduino Uno also includes connections to the GND and 3V pins, which are used to provide power to external devices and to ground the board.
The Arduino Uno consists of a total of 20 digital pins, 6 of which can be used for PWM output, and 6 analog input pins. The pinout also includes connections to the power supply, including the GND and 3V pins, as well as a number of other peripheral interfaces, such as I2C and SPI.
Digital Pins
The digital pins on the Arduino Uno can be used for both input and output and are designated as D0 to D13. These pins can be controlled using the digitalwrite and digitalread functions in the Arduino IDE.
Analog Pins
The analog pins on the Arduino Uno are designated as A0 to A5 and can be used to read analog signals, such as those from sensors. These pins are connected to an ADC (Analog-to-Digital Converter) on the ATmega328P microcontroller, which converts the analog signal into a digital representation that can be read by the microcontroller.
PWM Pins
The Arduino Uno provides 6 PWM pins, which can be used to control analog devices, such as motors and LEDs, by adjusting the duty cycle of a pulse. These pins are designated as D3, D5, D6, D9, D10, and D11.
I2C and SPI Interfaces
The Arduino Uno pinout also includes connections to the I2C and SPI interfaces, which allow electrical engineers to communicate with other devices and peripherals, such as sensors and actuators.
Power Pins
The power pins on the Arduino Uno include the GND and 3V pins, which are used to provide power to external devices and to ground the board. The 5V pin provides a regulated 5V supply, which can be used to power external devices, while the Vin pin can be used to power the board using an external power supply.
The ATmega328P microcontroller on the Arduino Uno is programmed using the ICSP (In-Circuit Serial Programming) header. This header provides access to the MOSI, SCK, and other signals required for programming the microcontroller. The Arduino Integrated Development Environment (IDE) provides an easy-to-use interface for programming the microcontroller and uploading code to the board.
The Arduino Uno schematic provides access to 14 digital pins, which can be used to control various devices, such as LEDs and sensors. Electrical engineers can use the digitalwrite function to set the state of a digital pin to either high or low. The state of the digital pin can be read using the digitalread function, which returns a value of either 0 or 1, depending on the state of the pin.
This example Arduino code shows how to control digital pins using digitalWrite() and digitalRead() functions. In this example, we'll use a push button to control an LED. When the button is pressed, the LED will turn on; when the button is released, the LED will turn off.
This code assumes that you have a normally open push button connected to digital pin 2 and an LED connected to digital pin 13. When the button is not pressed, the internal pull-up resistor will cause the button pin to read HIGH. When the button is pressed, it will connect the pin to ground, causing the pin to read LOW.
The Arduino Uno schematic provides access to 6 PWM (Pulse Width Modulation) pins, which can be used to control analog devices, such as motors and servos. PWM allows electrical engineers to control the brightness of LEDs, the speed of motors, and other devices by adjusting the duty cycle of the pulse. This provides a more versatile and smooth control of analog devices compared to using digital signals alone.
In this example, we'll use a potentiometer to control the brightness of an LED. The potentiometer will be read using an analog input, and the LED brightness will be controlled using a PWM output.
There are several ground (GND) pins on an Arduino Uno board. Typically, you can find at least 4 GND pins located on the board's power and ground bus along the edges of the board. These pins are labeled "GND" and are used to connect components to a common ground and complete the electrical circuit.
The "0" and "1" pins on an Arduino Uno refer to the RX (Receive) and TX (Transmit) pins, respectively. These are digital pins used for serial communication with other devices, such as a computer.
