UV 솔더 마스크 제거 도구 - 1/8″ 섕크

This works, but you need a specific technique no one tells you. Have the toolpath that removes the solder mask be slightly smaller than the copper pads, so that the edges of the copper are still covered by solder mask. This prevents the copper from being peeled off the fiberglass when this tool is used.

I've also found that a -0.2mm Z offset can be too much pressure. Depending on the solder mask brand, I've used either 0 Z offset, or -0.05mm.

So in short - this tool works but with a specific technique they don't document. In any case this is the only one you can get, so you can't complain, there are no other options.

Very good tool for removing solder masks
