Richard,

Not an answer that is directly applicable to the SMT industry, but if we
needed a temporary mask with Kaption tape in a microelectronics application,
where we dealt with hermetic enclosures, I would typically use an acrylic
adhesive rather than risk having any Si compounds floating around.  At the
time there were concerns about low molecular weight constituents that might
come back to bite us if using Si.

This was likely more phobia than fact, but at the time we were dealing with
a great deal of Mil, Space, and Implantable and prevailing logic considered
that to be the safest path.

FWIW - Steve C

Subject: [TN] Silicone adhesives on tapes

Do you think the silicone adhesive on Kapton and Shercon tapes can create a
manufacturing issue during conformal coating or for sensitive electronics?
Doug, I would be especially interested in your respected input on this
question.
