Top 8 Common PCB Assembly Problems and How to Fix Them
Printed Circuit Boards (PCBs) are the backbone of all modern electronics. But even a small assembly problem can lead to big functional problems, delays, and extra money in manufacturing.
Here are eight of the most common PCB assembly problems and how to fix them. This will help you make your assembly process smoother and keep your product quality high.

The most common PCB assembly problems include BOM issues, incorrect footprints, soldering defects, and poor thermal management. To fix these, ensure accurate BOM, proper design checks, and careful soldering processes.Fix these now to avoid expensive failures and make your production faster.
1. What are the errors in PCB assembly?
How to Fix:
To avoid these problems, make sure your design data is complete and right before you start assembly. Use a Design for Assembly (DFA) process to put your parts in the best places and keep them from running into each other. Do a thermal analysis to make sure heat goes where it needs to go.
2. BOM Problems
One of the most common problems is having the wrong Bill of Materials (BOM). If your BOM has mistakes, like missing parts or parts that aren’t right, you’ll have a hard time getting your boards made and they won’t work right.How to Fix:
