Introduction
When it comes to PCB (Printed Circuit Board) design, every decision impacts the performance, durability, and reliability of the final product. Whether you’re working on a consumer gadget, an industrial automation system, or IoT devices, following the right practices can make or break your project.
In this blog, we’ll explore the best things to do in PCB design, compare best vs. poor practices, and walk you through a real case study of Dimi Cube’s Flex PCB project engineered by Devomech Solutions.
Best Things to Do in PCB Design
1. Focus on Signal Integrity and Power Distribution
Signal integrity ensures that data signals travel without distortion, interference, or delays. Proper routing of high-speed signals, minimizing crosstalk, and using dedicated power and ground planes are crucial. Power distribution must be even and low impedance to avoid voltage drops and noise issues in sensitive components.
2. Ensure Proper Component Placement for Compactness and Accessibility
Good PCB layout starts with logical component grouping. Place power components near power inputs, keep analog and digital sections separate, and avoid unnecessary trace crossovers. This not only saves space but also improves debugging and rework accessibility. Poor placement often leads to longer traces, increased noise, and heat management issues.
3. Use Flexibility (Flex PCB) Where Design Constraints Demand Compact Performance
When space is limited like in wearables, IoT devices, or compact consumer electronics Flex PCBs are the go-to solution. They allow bending, folding, and compact stacking without sacrificing performance. However, proper bend radius and material selection must be considered to avoid mechanical stress failures.
4. Perform Rigorous Testing and Quality Assurance at Every Stage
Testing isn’t just the last step, it should be part of the entire design cycle. Continuity checks, EMI/ESD testing, power rail analysis, and stress tests are essential. This ensures the PCB won’t fail under real-world conditions. At Devomech, we integrate multiple test stages to guarantee performance before production.
5. Document Everything for Future Iterations and Improvements
A well-documented PCB design saves countless hours in troubleshooting and upgrading. This includes schematics, version control, Bill of Materials (BOM), and design files. Clear documentation makes collaboration smoother and supports scalability when new versions or product upgrades are required.

PCB Best Practices vs. Poor Practices
| Aspect | Best Practices | Poor Practices |
| Component Placement | Logical grouping, minimal crossovers, clear signal paths | Random placement, excessive via usage, overlapping traces |
| Power & Ground | Dedicated planes, low impedance, proper decoupling | No ground plane, poor decoupling, uneven distribution |
| Testing & Validation | Multiple test points, stress testing, quality check before final production | Minimal testing, ignoring EMI/ESD protection |
| Design Documentation | Clear schematics, version control, BOM updates | Missing files, incomplete BOM, no revision history |
| Thermal Management | Proper copper pours, thermal vias, heat sinks | Ignoring heat flow, no thermal analysis |
| Flex PCB Integration | Compact, reliable, stress-tested design | Ignoring bend radius, weak connections, mechanical stress points |
