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

Can you share some information relative to these questions about your conformal coating process: 1) What process controls do you use for conformal coating? 2) Do you perform manual conformal coating inspection? 3) Do you use AOI for inspecting confor

Most of the conformal coating manufacturers recommend verifying the compatibility of their coating with the solder mask, so it's no surprise that occassionally there will be such issues. Are you sure your conformal coat is completely cured? If your

Greetings...I have a customer that has an assembly that is conformal coated with Humiseal 1A33. This assembly has some components (resistors and FET's) that heated up during operation and has discolored the conformal coating around their location.

we have a Specialty coating system (SCS) precisoncoat spray coating system. we are using an acrylic coating material with about 80cp viscosity. The spraying pressure is around 4-6 psi. The main issue is the finish looking of the board. If we apply hi

Do a search in the archives on conformal coating and silicone conformal coat. A variety of companies make conformal coatings and the equipment to apply it. Coatings can be applied by dipping the board into the coating, brushing it on, or spraying i

We currently use both Humiseal and Conap with OA flux. The flux MUST me cleaned off the assembly before coating. I know that Humiseal has coatings that are compatiable with no cleans as long as your processes are defined properly before your coating

Seeking information on companies that manufacture conformal coating equipment. Pro's and Con's of UV / IR or air cured coatings. Masking verses selected coating systems. Thanks Wayne

Hi, Currently my company is running entek coated boards. But whenever there is a misprint, we cannot wash the boards as it would diminish the coating. Is there anyway to clean the boards without removing the coating or is there a way to re-coat

Have you considered spraying the coating? Check with the manufacturer of the epoxy to see if they recommend any equipment and whether or not the coating would have to be mixed with solvent to provide a smooth, thin even coat.
