Joseph, The first three items are easy. Its the "inexpensive" that trips us up. Here are some suggestions. 3M #42, Anti-static Kapton tape, solder mask (This is our standard wave solder mask for edge connectors and large holes.) 3M #5419, Anti-static Kapton tape, solder mask (has a sticker adhesive) 3M #5413, Kapton but not anti-static 3M #5414, polyvinyl alcohol backing which is water soluble and a synthetic water soluble adhesive designed to mask gold fingers during wave solder. Then there is 3M #219, a high performance green film backed tape, designed for conformal coating masking with a working temp of 275°F but not listed as anti-static. Hope this helps, Phil Nutting Manufacturing Engineer Kaiser Systems, Inc. -----Original Message----- From: Kane, Joseph [mailto:[log in to unmask]] Sent: Friday, December 01, 2000 9:43 AM To: [log in to unmask] Subject: [TN] Conformal Coat Masking Can anyone out there recommend a good masking tape? Desired properties, in approximate order of importance: 1. Withstands 85C indefinitely. 2. Sticks well, but peels off without leaving residue. 3. Antistatic a plus, but conductive probably not worth it (we use ionizing air blowers). 4. Inexpensive. Our coatings are mostly urethanes, manually sprayed.
