We have a C-740. I agree with the second pass statement. Be careful how much you overlap. Also make sure the board is very clean before you coat or its worthless. You will be able to get very accurate results without masking. Let me know if you need

My name is Stephanie Baldwin. I work for USI and have been following this forum. I would suggest that you give both USI and Asymtek the opportunity to coat a sample board for you. You can then compare the two technologies side by side. If possibl

We use nothing but silicones and have for at least the last 7 years. We don't have relays, but we do have motors. No issues with soldering, but our lines are constructed such that the last solder operation is a good distance from the coating or pot

We use (and have for some time) used No-clean on our radio boards with no problems. We also conformally coat with a platinum catalyzed, addition cure silicone coating with occassional problems. These silicones are prone to cure inhibition or retard

Shadow cure effects are dealt with by post cure mechanisims. New UV Coatings should have one, either heat or moisture cure. Basically UV primary cure starts off cure process, allows handling of the products. But UV is not suitable for all products

Is this an established process that is just now exhibiting these problems, or is this a brand new process you're just setting up? What is the rest of your process like? What is done to the boards before you coat them? Water washed? Solvent washed? Sa

Hi, Use nitrile or latex gloves for handling your product from your pre-coating cleaning step onward. In my opinion, conformal coating should be isolated from the rest of the factory floor. I'm not saying you need a clean room or even a white room.

A customer wants to coat a no-clean assembly to cut cost and cycle time. I know what wave flux I can use to make it work, but the Indium SMQ92J paste we use causes dewets. Any other no-clean pastes out there that play nice with acrylic?

I use Trace and certainly recommend them. I actually just had this test done last week. Adhesion test per ASTM-3359 Method B. We use Humiseal 1B73, which is similar to what you use. Is your soldermask "active" enough for this coating? I believe
