Peelable solder mask works well. Hand dispense and peel off after. Paint sticks work OK, but it depends on the mfger of the paint stick. In both methods you hand apply after screen print. Your Dek can be taught pads to get by. You may have to te

Thanks for the acvice, Dave and John. Like I stated above, I didn't feel comfortable with changing wave parameters since I knew that we'd be compromising our wave quality. I'll try the peelable mask thing, reprofile, and let you guys know what i fo

| I have gold fingers that I want to mask when running over the wave without pallets. They're on the leading edge of the board. I recall seeing rubber boots that slid onto the fingers to mask them. Pop 'em on before the wave; pop' em off after and

Silicone-based coatings "repel" most foreign,non-compatible materials like peelable solder mask, and rubber or vinyl boots. The result is, uncured material around the vicinity of where the boot was. Trust me. Been there and done that. As a rookie

Pink Lady refers to solder stop, or temporary solder mask. There are a couple of types. Peelable, which you must peel off after processing, before wash, and of course before you ship. There is also a water soluble version, which dissolves in the w
