The first step of the through hole plating process is the make sure the PC Board is clean.
We need to remove any protective coatings, grease, oil, dirt or tarnish.
I use a commercial abrasive cleaner for this step.
- Commercial abrasive cleaner
- Scrubbing pad
- Backing board
- Running water
- Compressed air
- Be sure not to bend or warp the board in any way.
- Clean all the cleanser out of the through holes thoroughly
