Has someone had really good experience with the softening of silicone conformal coating using a specific chemical? One of our clients just came in with a board with Dow 1502 silicone coating on it. We generally mechanically remove the coating for re

Interesting stuff. I must admit that I am unfamiliar with that product but we use quite a bit of Dow and they are overall excellent silicone coatings. We do nothing but conformal coating here and bubbles are usually from curing to quickly. Without kn

Gentlemen, Have no idea how to remove fully polymerized silicone elastomer resides from a particular product. Product housing has not been designed for filling. Having polymerized, elastomer (DowCorning SylGard 160)expands and gets out of filling ho

Hey that was me way back! Anyways, use Dow 3140 (self leveling) or Dow 3145 (peanut butter consistency) and call it a day. No out gassing/acidic properties. 3140 also contains a UV tracer for black light inspection. Any tall caps should be epoxied if

Being in the automotive electronics industry, we use silicone (Dow 4105 is one in particular). I'll ask the same question - What are your reliability requirements?

Yes we are using "silicones", but to find this contaminant we were looking for "silicon" the element by SEM/EDS. We use Dow materials and my contact there is checking to see if they have any info.

I was wondering what Dow Corning has done with all those silicone breast implants? B or C cup would work nicely (in the stencil printer).

Because our boards are heavily heatsinked with dow 340 which never hardens and I am afraid I will not only wash off the flux but the heatsink compound as well.

What is everyone using to secure their caps on products that go through ESS testing. We have been using Dow 3140 RTV but it takes too long to dry and I read that RTV isnt the best anyhow. Any suggestions...
