Frequently asked questions
Can I use it as an etch resist on PCBs?
Yes. Draw the pattern on the copper side of the board, let the ink dry fully, then etch. The waterproof ink protects the drawn traces from the etchant.
Is it suitable for marking components on a board?
It can be used to mark labels or reference codes on a board surface. Test it on a scrap board first to confirm that the ink adheres to your board material.
