We are using a manual DIP conformal coating method with an acrylic coating
and building assemblies to the IPC-610 specification.

1.  Are there other specifications which apply to conformal coating?  610
is brief on the subject.

2.  Our biggest defect is bubbles in the coating.  We are finding that dip
angle, insertion rate and extraction rates all effect the amount of bubbles
on the finished assembly.  Does anyone have similar experience or advice?

3.  Does anyone know of available dipping equipment and / or drying
equipment?  Our goal is to be able to dip 250 assemblies per day (1000
assemblies per day panelized 4 up).

Thank You

Cory Steeby
