Troubleshooting Common Issues in PCB Boards

Identifying errors in printed boards can be complex, but several common issues usually arise. Firstly, examine for visible signs like cracked traces, broken components, or incorrect connections. A tester is crucial to verify for shorts and opens. Moreover, consider potential supply delivery issues – a low power supply can cause sporadic behavior. Finally, study the layout to ensure component positioning and line integrity – faulty routing can generate noise.
