PCB Cleaning Challenges. | 24 July, 2020

Hello all,

We have a new model running upon analysis I found one challenge while cleaning the send side boards.

We have a thru hole in top where it's bottom ends are covered inside the shield.

Operator find difficult to clean as it has high chance to affect the bottom side component.

Kindly provide your valuable suggestions on how to clean this.

Any equipment available like vaccum method to remove the paste in via hole.

Refer the attached image for understanding.

Please try to use the steam aging tester and make a try !

When the water temp up to +100℃, Put your new model into the water tank.

This +100℃ hot and steam water may remove the paste in via hole. Thank you.

The usual accepted process would be to assemble and clean the board per the usual process, then install the shield with no-clean flux/solder.

Cheers, ..rob
