Troubleshooting Common Issues in PCB Boards

Identifying problems in PCB boards can be difficult, but several frequent issues usually arise. Initially, inspect for visible signs like cracked traces, broken components, or incorrect soldering. A multimeter is vital to check for lows and discontinuities. Moreover, evaluate potential supply provision issues – a weak power supply can cause sporadic operation. Finally, review the layout to confirm component placement and line integrity – incorrect routing can create interference.
