Conformal Coat Thickness

Electronics Forum | Mon Jul 23 17:49:04 EDT 2007 | davef

We know nothing of DeFelsko, but do understand how they distinguish between the solder mask and the conformal coat. DeFelsko manufactures hand-held, non-destructive coating thickness gages that are ideal for measuring the dry film thickness of confo

We use Dow 2620 silicone conformal coat applied with PVA1000 sprayer machine. If used on a daily bases, we have no problem. If we let the machine sit idle for over a week, we will get bubbles in the conformal coating. Sometimes, purging the line w

this is one of my project. I have tried to remove coating only on those areas with alcohol and thinner, then program the machine to coat the removed area again. But the result obviously shows that two different tones of coating on the board. I also

First, it appears that your solder mask and your coating material appear to be incompatible. Second, IPA leaves a residue that's probably not compatible with your coating material, either. IPC-HDBK-830 - Guidelines for Design, Selection and Applic

10.4. Pre-Cure Examination. Immediately after material application, the uncured conformal coating shall be examined for: a. Bubbles and Air Entrapments. These defects shall be broken by vacuum, with a sharp probe, or other appropriate tools. b. Bridg

While there may not be any specific requirement to cleaning prior to coating, cleaning an assembly prior to coating will only serve to increase the reliability and integrity of the coating. Some residues from low-solids fluxes can interact with conf

Conformal Coating on Circuit Boards

Electronics Forum | Thu Jan 27 08:52:05 EST 2000 | Todd A. Braun

We currently use a silicon conformal coating on many of our manufactured circuit boards and are experiencing situations where the coating doesn't conform. For example, on the sharp edges of components and corners of leads it pulls away before curing
