AI Technical Summary

⚠Technical Problem

When soldering flexible circuit boards to rigid circuit boards, operators cannot check whether there is solder bridging between adjacent pads, which can lead to short circuit risks.

⚗Method used

A cutout area is created on the flexible circuit board to isolate adjacent pads. The cutout area is used to observe whether there is solder bridging during the soldering process and to deal with it in a timely manner.

🎯Benefits of technology

This effectively avoids short circuits caused by solder bridging between adjacent pads, improves the observability and stability of the soldering process, and reduces the risk of short circuits on the battery protection board.
