If you apply the RTV after coating, what happens to bond strength since you are now bonding to the coating and not the board? Will the caps still survive vibration and shock? I specify applying RTV before coating for this reason. Am I correct? I als

A common way to add traces to a fabricated board is to print polymer thick film [PTF] conductive ink. PTF suppliers are: * Du Pont de Nemours, E. I. & Co. - Research Triangle Park, NC * Ercon, Inc. - Wareham, MA * Dow Corning� * Asahi Chemical Res

IMHO I would avoid sprayed silicones like the plague. They can travel around your facility and cause solder wetting issues that you will never know the root cause for. Also found this e-drive article on using silicones around motors and relays. Loo

Kic Thermal used Pyropel. Cut with a razor blade and glue together with a good Dow Corning high temperature silicone. You can buy Pyropel in various thicknesses. It is not cheap. $100.00 for a 24" X 24" X 3/16" sheet. You can buy at McMaster Car

Having solder flow issues on gold pads. Issues started when supplier switched adhesive tape used to cover pads during varnish process. By running SEM/EDX and XPS analysis it has been determined that the new tape leaves behind a thicker organic residu

Hello, Looking for a solution to silicon conformal coating wicking up into connectors. We build IPC-A-610 class 2. We are using a PVA 650 with Dow Corning 1-2577 conformal coating. We have solder joints that must be coated 1.25mm from the connecto

Looking into possibly receiving samples of polyester masking dots for conformal coating. Our usage of polymide dots have really increased in the past months and we're always looking for a reduction in costs. The only information I've found is that po

We are in the process of revamping our conformal coating room. Presently, we have a C-740 Nordson Asymtek coating machine that sprays most of our boards with Dow Corning 2577. We are spending a lot of time masking boards and are thinking of upgrading

| Can someone suggest what material I have to use to protect components by electrical discharge on ptfe based boards? | It should have high resistivity, thermal stability (-40 +70 'C),perfect adherence on ptfe... | Many tahnks | Don't know what you

Wow, I cut first cut my teeth in the Industrial motor control industry. My 1st company made motor control products like variable speed drives, solid state overload relays, soft starts, etc. and in our shop, we used nothing BUT Dow Corning silicone p
