Troubleshooting Common Issues in PCB Boards

Identifying faults in PCB boards can be challenging, but several typical issues usually arise. Initially, inspect for obvious signs like damaged traces, missing components, or faulty soldering. A tester is crucial to verify for failures and discontinuities. Furthermore, analyze potential supply distribution issues – a weak power supply can cause erratic behavior. Finally, review the design to confirm component location and signal integrity – incorrect routing can generate interference.
