PCB Design

PCB Design

Printed circuit board (PCB) design is based on circuit schematics to realize the functions required by the circuit designer. This is a complex process that includes several steps, such as schematic drawing, layout design, DFM and testing.

A good PCB design can create functional, reliable, and cost-effective circuit boards that meet the electrical and physical requirements of the devices they will be used in. PCB design is critical to ensuring the proper operation of devices and minimizing the risks of electrical shorts, interference, and other problems that can arise from poor design. PCBs are widely used in various electronic devices, from small consumer products to large industrial machines.

Signal Integrity (SI) Analysis can assess and optimize the quality of electrical signals as they travel through a PCB. It is mainly used to maintain the integrity of signals, especially in high-speed circuits, so that they can transmit without distortion or degradation. SI analysis solves issues such as signal reflection, crosstalk, and electromagnetic interference.

EMC Test

For every new PCB case, electromagnetic compatibility (EMC) is an important process in the development and certification of electronic devices. By evaluating a device's ability to function properly in its intended electromagnetic environment while limiting the unintentional generation, propagation, and reception of electromagnetic energy, we can make sure the device does not cause interference with other electronic equipment and can withstand external electromagnetic disturbances.

Frequently Asked Questions

Why is my 4-layer PCB experiencing signal interference, and how do I fix it?
Signal interference often stems from incorrect layer stack order—ensure signal layers (Top/Bottom) are adjacent to reference planes (GND/Power). Avoid placing power and ground planes in reverse order, and use continuous reference planes for high-speed signals to minimize reflection. Use the Layer Stack Manager in your design tool to reorder layers, and run a signal integrity analysis before finalizing.
How do I resolve impedance control mismatches in Altium Designer?
Mismatches happen when layer spacing, copper thickness, or material parameters are off. Enable the Impedance Calculation feature in Layer Stack Manager, input your substrate’s dielectric constant (FR4 = 4.4 typical), and adjust layer spacing (0.2–0.4mm for signal-GND layers). Double-check that your trace width matches the calculated impedance (50Ω or 100Ω for differential pairs).
My PCB design fails DRC checks due to power plane splitting—what’s wrong?
Power plane splitting errors usually come from insufficient spacing between voltage domains (e.g., 3.3V and 5V) or crossed signal paths. Use the Split Planes tool to create clear boundaries between power regions, leave at least 1mm spacing between splits, and avoid routing signals across different power domains. Run a DRC check after splitting to catch overlaps.
Why won’t my PCB’s inner power layer connect properly to components?
This is often caused by not enabling the Negative Layer option for inner power/GND layers. In your design tool, go to layer properties and select "Negative Layer" for inner planes. Use Plane Connect (not Net Tie) to link components to the power layer, and ensure vias are set to "Thermal Relief" to prevent cold joints during manufacturing.
As a beginner, which PCB design software should I choose—KiCad, Altium, or Eagle?
KiCad is best for hobbyists/beginners (free, open-source, strong community support). Altium Designer works for professionals (robust for high-speed, multi-layer designs but paid). Eagle balances ease of use and features (good for small-to-medium projects). Start with KiCad to learn basics, then switch to Altium if you need advanced tools for industrial projects.
How do I choose the right substrate material for my PCB design?
FR4 is the standard for most consumer electronics (affordable, good electrical performance). Use high-frequency substrates (e.g., Rogers) for RF/microwave designs, and flexible substrates (e.g., polyimide) for wearable devices. Consider operating temperature—industrial PCBs may need heat-resistant materials to avoid warping.
What’s the biggest mistake new PCB designers make, and how to avoid it?
Skipping design rule checks (DRC) and ignoring manufacturability. Always run DRC before sending files to manufacturing—pay attention to minimum line spacing, hole sizes, and trace width. Consult your manufacturer’s design guidelines (e.g., minimum feature sizes) early in the process to avoid rework.
How can I reduce EMI in my PCB design without increasing costs?
Keep power loops small by placing decoupling capacitors close to IC power pins. Use solid ground planes instead of ground traces, and avoid long, parallel signal traces (they cause crosstalk). Ensure power and ground planes are properly paired, and route high-speed signals (e.g., USB, HDMI) away from power traces.
Why do my PCB prototypes have soldering issues, and how to fix it?
Soldering problems often relate to pad size or thermal relief settings. Make sure pad sizes match component leads (follow IPC standards), and use thermal relief vias for large pads (prevents heat dissipation during soldering). Avoid placing components too close together—leave at least 0.5mm spacing for assembly access.
How do I verify my PCB design is ready for manufacturing?
Run a full DRC check (fix all errors, not just warnings). Generate and review Gerber files (ensure all layers are included: signal, power, silkscreen, solder mask). Use a 3D viewer to check component placement and mechanical fit. Send a sample design to your manufacturer for a pre-production review—most offer free checks for manufacturability.
