Alternatives are: * DSCC Columbus continues to maintain the QPL for MIL-I-46058C. [Engineering is unlikely to change.] * Use International Electrotechnical Commission Standard, IEC 61086 - Coatings for loaded printed wire boards (conformal coatings)

Many companies use IPC-CC-830B as a replacement for the deactivated MIL-I-46058 conformal coating standard.

We have PVA 350 benchtop dispensing equipement with humiseal 1A33 CC material. is there any moisture measurement process in conformal coating material?

Humiseal says, "UV cure – These materials are also more difficult to repair as they are the most chemically resistant and mechanically tough of all conformal coatings. Removal is possible locally by using powder abrasion."

The good old days weren't all that bad. When I needed to have a specification callout for a conformal coating on an engineering drawing, I just used MIL-I-46058, type UR (for example), and the drawing checkers were quite happy. Since MIL-I-46058 ha

Curtiss-Wright uses MIL-I-46058 at present. Any suggestions on how to approach engineering and update the drawings for new contracts?

The coating thickness is more a property of the individual coating itself. The 0.03 - 0.13 is based on average properties of acrylics in general. It's like trying to pour 3 mils of motor oil on a table. The material will find it's own thickness.

dave, where I work they are having the same problems with 1B31 acrylic. The coating thickness is 6-8 mils dried so that have to do several passes with an air dry between them and a final oven cure. They think that it might be related to the heating r

| | We have experienced poor adhesion of acrylic conformal coating to plastic bodied IC�s. The observed symptoms of this are a blistering or lifting of the coating at the surface of the component, although peel testing has revealed that this is not
