High temperature, low viscosity epoxy
« on: January 14, 2018, 11:16:17 am »
If I am going to make a BGA mock up (a small module in a BGA package), what kind of encapsulant should I use?
It seems like IC related materials are only traded within the IC business, and they rarely end up in the wild.
Is there any way I can get some molding compounds (quartz filled plastic beads) or 2-part epoxy that will survive SAC305 reflow temperature?

I'm looking for a small package, less than 0.5 kG. Any suggestions where can I get my hands on such materials?

Research electronic "potting" materials. Some of that should be high temp. Should be available from Mouser, Digikey, etc.

In the USA I have used the Ellsworth high temperature epoxy successfully.
A great company to work with

Silicone resin any good for your application? http://uk.farnell.com/electrolube/sc3001rp250g/resin-silicone-optically-clear/dp/2075077

Low viscosity, withstands 250*C for 30min, optically clear.
