Anyone using Acrylic conformal coatings? We're looking into using one, but one of the drawbacks is the odor. We have problems with any material that has a distinctive odor and our operators. Also the lines we would use it require repair after coat

We've been conformally coating for years (primarily silicones) and yes we have issues with both equipment and materials. We just don't have experience with acrylics.

We too have recently got involved with conformal coating. We have had a good deal of sucess of cleaning the material off with gun wash. An aggessive solvent that does not harm the electronics and evaporates leaving no film

Does anyone know, what causes the orange peel affect when spraying pcbs with conformal coating ? Are there ways of minimising or eliminating this ? Is is possible to achieve a glass like finish ? if so how Thanks Sam

Some questions: Is the peelable/spot masking only being applied to the earthing points on the one side or to both sides? Is the peelable mask you are using specifically designed for coating masking or is it the same as that you use for masking sold

Why can't you conformally coat the BGA? We do on some of our lines with no adverse affects.

You should look at the Asymtek Conformal Coating machines. The C-740 is easy to program, high throughput and proven repeatability. Used at top electronics and automotive manufacturing sites throughout Europe, Asia-pacific, and the Americas.

I know Micro Care made a unit that removed conformal coating with compressed air and a solvent. But they no longer make it. Does anyone have the 2000 version of this unit and may want to sell it or know of another compressed air solvent solution, p

Does anyone have any experience with underfill of HD connectors? New customer wishes to underfill 6 HD connectors that have been pressed into PCB. Capillary action is causing the conformal coat to wick up into connector. Material is acrylic.
