Hi first DS65 version is a specific dilution for dispensing machine, in this case the typical process is following: application of the conformal coating extraction of solvent (low extraction power is better)2minutes and drying the drying can be done

Q1.Does anyone know a way to verify the amount of OSP coating on a board? A1. There is no specification. Thickness is difficult to measure. Thickness is product related. There are at least six major suppliers. Years ago, here on SMTnet, J Medernach s

We are in the process of validating Silicon 1C55 (thermal cure) conformal coating over Alpha LR725 solder paste. I am looking for anyone who may be using this process, or has been exposed to someone who is doing this process. Our concern is with the

Has anyone experienced a problem with conformal coating adhesion to IS-410 boards? We are having problems with one suppliers boards. IS-410 boards from other suppliers are fine and all FR-4 boards that I have looked at are fine. We are using Conap

Hello Hai, The first step is to determine where in the process the bubbles are being generated - either during coating or during curing. You can easily check this by letting a few boards air dry (no oven) and comparing them to the oven-cured ones. I

Sorry to interfere with Dave F, but perhaps your IAg finishes have issues with process residues from the boardhouse. What is the base material of your ConAP conformal coating - acrylic, silicone, polyurethane? We do CC (acrylic) and IAg and never h

It appears that the two different boards we are having issues with are the only imersion silver boards that we process. Anyone have simililar issues with imersion silver? Is Dave F. on vacation? I would be willing to consider input from moon man at

That is true; it is not a fast process but it is selective and uses minimal material. Also true that the application consistency has to be checked and sometimes minor adjustments made at the beginning of a run. We have a program that checks for a con
