You should have no problem. We use a very dated Asymtek machine (Automove 303) retrofitted for dispensing, air over syringe. It took time and some tinkering with. But all things considered, we're able to achieve remarkable results. I would recommend

We'd repair a drop board like this. Here's what our old friend Jeff Ferry said is a published article ... When boards lose their edge: when the corner of a circuit board breaks or is damaged, the problem cannot be ignored by Jeff Ferry One of the m

You weren't specific about the OSP that you use. We use Entek Plus CU-106A. Yes, just about everything removes Entek, especially if there's heat involved. Ethone states: * Alcohol strips 70% of the coating * Water removes 15% * Kyzen Lonox only t

The easy part is to determine which parts should be coated. The harder part is making sure the parts that should not be coated do not get coated. I don't even want to think about the amount of labor and materials I've lost due to conformal coat get

It will be hard to solder metal that finish by any coating. So you should remove the coating first. You need strong acid to remove coating. After you solder both then you can silder finish esay.

yes, the void should not expose the conductor or bridge the conductor, the coating there should be thick as IPC required but you need minimize the voids and bubbles. ALso for those small chips, a void or bubble on it means possible ECM, normlly shou

Can anyone tell me what parts on the pwb should be protected by the conformal coating, and what parts can be free of the coating (such as the areas without components, traces, brides lands)? we were follow MIL standard 2000 and IPC-A-610 class 3. Tha

You can inspect joints using an X-ray machine and we use a sand-blaster type machine which blasts (Starch) to remove the conformal coating. (Carbo Blast). However; the inspection should be done prior to Coating, as we all know some jobs are rushed t

I have Through Hole Assembly Boards that require Conformal Coating but the customer did not specify which area or parts should not be coated. Upon asking them they are also not sure about it. I have Transformers, PLCC's on a socket, IC's on a Socket
