Troubleshooting Common Issues in PCB Boards

Identifying faults in circuit boards can be complex, but several common issues usually arise. Initially, look for obvious signs like burnt traces, broken components, or incorrect joint. A instrument is vital to check for lows and opens. Besides, consider potential voltage provision issues – a low power supply can lead to erratic operation. Finally, review the layout to verify component placement and line integrity – improper routing can introduce distortion.
