| Hi, Friends, | Could you please recommend me some solder mask materials and equitements for high quality solder mask? Details such as company name, phone numer et al are welcomed. Thanks! | Have a good day | Xingsheng Xingsheng: Consider the follo

Controlling age sensitive materials on the floor

We are required by AS9100 to keep expired material/chemicals off the floor. Examples include solder paste, flux, adhesives, conformal coating, etc. We have a system in place to prevent such occurrences but once in a while something is not accounted f

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

You should be able to obtain a smooth finish. A "glass-like finish" is in part a function of the coating material, assuming good process. When we see "orange peel" conformal coating, we think moisture from the spray room environment, conpressor, et

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."

Thanks for the info Sarason. The UVCL is a Urethane. Did not want that hard of finish (for solder rework issues). We like the Acrylic as acetone will remove cured material for solder rework.

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

Can anyone recommend machine for conformal coating? I know that it depends on the coating material, but I am interested in practical advices - like experience with existing equipment, maintenance issues etc. Thanks in advance. - Deni

Hi Guys, I have few question would like to ask regarding pcb conformal coating: 1. Can I know which masking material is the best for easy apply, fast cure, fast & easy to remove after coating & baking. And no chemical reaction which will whiten the

Electronics Forum | Wed Sep 30 11:32:45 EDT 2009 | pbarton

What type of conformal coating are you using and are you allowing the coating to migrate under the device in question? If you are allowing the coating unbder the BGA the problem could be CTE of coating is much greater than that of the BGA balls/sold
