Manufacturing Summary

We produced this double-sided FR4 PCB requiring precise process control to maintain trace integrity and pad definition. Our team executed imaging and etching under tight tolerance settings to ensure uniform feature sizes across the full panel.

Solder mask application was completed with exact registration before molten solder coating. Hot air leveling followed with calibrated air knife pressure and temperature to achieve consistent coating thickness without bridging.

The main challenge of solder thickness variation was managed through continuous in-process monitoring and parameter adjustment. The order was completed in 1.5 days with 100% first-pass electrical test yield.
