Hi, Some nano coat supplier said that you can drop water to the surface where the coating supposed to present before to check. If it's beading, it's still there. I take it that you meant by self in-house wiping of coating, yes? Stencil supplier nan

Put a known thickness gage next to your boards to be coated. Then coat it in the same pass as your boards. Measure the "new" thickness of your gage and subtract the difference. That will be your coating thickness. This is assuming your coating your o

We use paper labels with a protective coating to prevent browning during reflow. We've had no problems coating over these labels with our silicone. If your coating is not silicone, a Sharpie should print on the coating.

Contact the coating manufacturer to get their response. We use many different coatings every day and they all glow differently but that has no affect on the coating itself. As stated earlier, it's job is only as an inspection tool to identify where

Josh: Do you measure the thickness of the coupon prior to coating or do you peal the coating and measure that?

Generally, solder connections and leads are conformal coated, unless there is a reason not to coat them.

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
