I haven't used this particular CC, but...found this in their data sheet: "AVR 80 BA Conformal Coating will be touch dry after 15 - 20 minutes at room temperature and does not require a thermal cure. The full properties of the coating will be obtaine

Hi Ju Yong, The PCB are dry in an airseal cabinet(Staging Chamber) before IR Oven. The bubbles show at around body and solder joint area. You mean the moisture will create bubbles ? Able to advice the humidity and temperature that you are using in

I coated three other bare boards on one side this morning from two different suppliers. Two of them had exceptional adhesion and one was so-so. I ran them through the reflow oven, coated them and got the same results on the other side, so it does not

Cory, I've got a lot of experience of testing of this type. The physical (not chemical) nature of the flux residues is the crucial issue in compatibility. If you have a softer residue (either caused by a thick initial solder paste deposit, or a low p
