The invention of PCBs has made the electronics world simple by offering compact and reliable connections of components in devices as simple as a mobile phone to high-tech medical equipment.
Before the advent of PCBs, circuits were made using huge and clumsy wires together with point-to-point connections. These were prone to errors and very hard to maintain.
The invention of the PCB allowed the opening of precise, repeatable, and scalable designs to electronics, enabling them to shrink in size with an increase in functionality.
This has now been succeeded by complexity in devices, multi-layering, and advanced techniques for the management of heat, signal integrity, and manufacturing efficiency that set a PCB design today apart—thereby making it one of the cornerstones of modern technology.
What is PCB Design?
PCB, is an electronic assembly that is used to establish electrical connections among various components in an electric circuit. In addition to the electrical connection, PCB boards also provide mechanical support to these components.
Therefore, these boards hold special value in modern-day electronics. However, to translate the physical PCB into a functional component of modern technology, precise and thoughtful design is crucial.
Before delving into how these boards are designed, let’s start off with knowing what PCB design actually means. Just like any product that goes for manufacturing needs to be designed in the first place, PCB boards, in the same way, must be designed before they can be built. This is accomplished using PCB circuit board design CAD tools.
Fundamentals of PCB Design
The fundamentals of any PCB design involve understanding the circuit’s requirement and the optimal component placement with careful routing of traces. Before we start designing a PCB, it is necessary to understand the electrical parameters required in terms of current maxima, voltage, signal type, capacitance limitations, impedance characteristics, shielding considerations, etc.
We will also need to find the most optimal placement for every component to ensure efficient thermal management, testability, manufacturability, etc. The traces are then routed with a view to providing efficient connectivity between electrical components.
PCB Design and Layout Process
FS Circuits’ professional PCB design team will provide you with feasible solutions based on your project files. If you don’t know where to start
The general PCB design and layout process involves the following steps:
After the fundamentals have been covered, the PCB design process starts with creating the schematic. The schematic is like a blueprint for the PCB that shows each part, such as resistors, capacitors, etc., and their connections. These parts are represented using logic symbols. The wires drawn on this schematic diagram are called nets. They represent either memory or data circuits.
Circuit Simulation
After the parts and nets have been organized on the schematic, the next step is to verify whether the circuit works as intended. To do this, we simulate our circuits in a simulation program with an Integrated Circuit Emphasis tool.
PCB Layout Planning
In this step, we plan the physical layout of the board and components on the board. We identify the board dimensions, decide on the number of layers and identify critical areas like power supply regions.
Design for Manufacturability
In this practice, we design PCB in such a way that it simplifies manufacturing, reduces costs, and minimizes potential errors. Using DFM techniques allows you to optimize your manufacturing process, launch your product on time, and ensure high-quality production and compliance.
Design for Testability
Design engineers need to ensure that the PCB testing process is efficient while minimizing the testing cost. Key DFT practices include adding test points for critical signals, ensuring access for in-circuit testing (ICT), and incorporating JTAG for boundary scan testing. DFT also involves simplifying circuit complexity and designing test modes that allow for isolated testing of board sections.
PCB Design and Assembly
Finally, the design is translated into physical PCBs. This involves generating fabrication files and sending them to the manufacturer. After fabrication, components are assembled onto the boards.
Advanced PCB Design Topics
In advanced PCB design, engineers face a range of complex challenges that require specialized knowledge and skills. Below are three critical sub-topics within this area:
Any electronic device that works at high speed and frequency brings with it several issues that have to be taken into consideration. They include, but are not limited to, signal integrity, timing, noise, etc.
Signal integrity means the quality and stability of electrical signals while they are moving through a PCB. Fast-switching signals in high-speed electronics are more prone to various types of distortions, which can result in miscommunication during data transmission. These are some common problems in signal integrity: reflection, crosstalk, attenuation, skew, and others.
Moreover, both internal and external noises can interfere with the signals and again result in an error. Further, accurate timing is required to synchronize signals to avoid errors in data; hence, much attention has to be given to designing and analyzing the system.
All these can be avoided, however, by first gaining insight into the operating frequency and the data rates associated with the circuit. Material selection with low dielectric constants will ensure less signal loss.
Control of impedance through appropriate PCB stack-up is necessary to ensure the integrity of signals. Routing strategies include controlled impedance and differential pair routing to minimize reflections and crosstalk. EMI/EMC considerations in reducing noise, such as proper grounding and shielding, are applied.
Finally, thermal management techniques ensure that the circuit will work within safe temperature limits. Simulation tools are often used to check a design before its manufacture.
EMI/EMC Compliance
EMI/EMC compliance ensures that the electronics work without generating and being susceptible to electromagnetic interference. To achieve compliance, we often use methods involving proper grounding, shielding, and filtering to reduce emissions and susceptibility.
Moreover, careful component placement and trace routing reduce noise and crosstalk, while decoupling capacitors, together with ferrite beads, help filter high-frequency noise.
Thermal Management Techniques
Advanced PCB design ensures efficient thermal management techniques, which involve heat sinks that dissipate heat from high-power components and thermal vias to help in the transfer of heat through the layers of the PCB.
Copper pours and thick copper layers are used to spread out the heat across the board. Component placement helps in enhancing airflow and avoiding hotspots. Thermal interface materials improve heat transfer between the component and the heat sink.
PCB Design Tools and Software
There are several PCB design tools and software available in the market. A few popular of them are explained below:
Altium Designer
Altium Designer is a comprehensive design tool used for designing advanced boards such as HDI, flex and rigid-flex PCBs. This has an easy-to-use interface and allows 3D visualizations of the board.
Moreover, using this tool you can collaborate with multiple designers at once. The design collaboration tools include Altium 365 for real-time teamwork, cloud storage, and version control with Git and SVN. It supports MCAD-ECAD collaboration for seamless interaction between electrical and mechanical design.
KiCad
KiCad is a handy PCB software that is open-source and free. Kicad is available for various operating systems like Linux, Windows, and macOS. The Design Rule Check function in Kicad verifies design data against predefined rules.
KiCad offers design collaboration through Git for version control, allowing teams to manage and track PCB design changes. Its integration with manufacturing tools includes generating industry-standard Gerber files, drill files, and BOMs.
KiCad also supports integration with simulators like SPICE and export to mechanical CAD formats like STEP for 3D modeling.
Eagle
One of the unique features of Eagle is a larger component library with electronic components, symbols, and footprints. Thus, the user need not create many components manually.
Eagle also connects smoothly with other design softwares like Fusion 360 and Eagle premium. The only disadvantage is that you will get only limited features for the free version.
Choosing a PCB Design Service Provider
Before choosing the right PCB design service provider, consider the following factors:
