Subject: [TN] Low Outgassing, Black Sealant / Underfill

Good Morning, and Happy Monday.

A couple of questions for anyone:

We have a lighting application where we are getting light reflection off
two specific solder joints (we're so lucky to still use Sn63Pb37 they
are just TOO shiny!), so I am looking for a method to cover those joints
with a black (or dark gray) sealant.  This would need to be a low
out-gassing material.  Does anyone know of any such material?  Is there
such a thing as black pigmented conformal coating?

The second question would be for this same product.  I also have a need
to seal around the base of some LEDs to prevent moisture ingress to the
bottom only terminations.  Would perimeter sealing be sufficient?  How
does one determine when they need to underfill vs perimeter seal?

Thanks!

Kevin Glidden
