Fellow techies, a BGA related question. We're just starting to design BGA's
into some new designs which are class 3 high rel assemblies and I am asking
myself questions about the ability to adequately conformally coat under the
packages. Our standard coating is a solvent based acrylic and we are using a
456PBGA device and a 429CBGA device, both on 1.27mm pitch, as the maximum
sizes so far and I'd be interested to hear what other class 3 builders have
experienced when applying the coating.
Regards
