Amol, If you want, have a look at a short technical paper I put in the
August  2002 IPC Review, describing the experimentation done to set up an
automated conformal coater. Summer of 2010 that authority Doug Pauls looked
at it and did not recommend putting it in the trash, so it may have some
worthwhile ideas. The website IPC archives for that publication do not go
back to 2002. Let me know if you want to see it and I will dig up a copy.

Subject: [TN] Chemtronics Konform SR Conformal Coating

Dear Technetters,

I am being tasked to setup the above coating with the PVA automatic
spray/dispense machine (fine spray head and the needle dispense head).
The coating comes in two forms, the Konform SR and Konform SR High
viscosity, and some mixing is involved to arrive at the optimal viscosity. I
plan to talk to PVA and get their expertise in setting up the machine and
eventually setting up a DOE to determine the optimal viscosity specification
limits. However I wanted to know if there are any techentters already
spraying this coating thru automated conformal coating equipment. I was
hoping to talk to someone who is willing to share his/her experience with
this coating and hopefully obtain information on some "good" starting values

 

Thanks,

Amol
