Hello everybody, This is my first time mailing to the list. I'll get straight to the point - you see, a product of my company has a plated through-hole that must not be soldered. The past solution was to cover the whole thing with a kapton tape before running it through the wave. Now we have suggestions of using a plug or water-soluble masking tape. I was wondering if any of you have any experience in this matter and could share anything with me. Thanks in advance.
