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

We built our own coating system by mounting a Universal Robots UR5 to an edge conveyor between a magazine unloader and magazine loader. The robot has a needle dispenser on the head. We chose a needle dispense process to avoid aerosols and complex ven

Well then, maybe it's an incompatibilty between the soldermask and the coating, possibly due to undercuring of the soldermask. Thoughts are: * Some suppliers provide their thoughts on the compatibility of their product with other suppliers. For ins

Terry The SCC3 product is a vinyl modified silicone. It is less able to perform at low temps as it becomes brittle. It is not easy to repair because it is essentially silicone. It is not a qualified material to the MIL-I-46058 Spec. Are you sure yo

| | I am having a problem with Entek coated boards. The solder past seem to just ball up on the pads. I had no problems with the board when it was hot air leveled. The board is double sided surface mount. I have tried adjusting the oven profiles m

Steve I did investigate the transparent nano coat before for performance. We examined 3 different assemblies based in design criteria. In more simplistic designs it is not worth having it. On more challenging designs it is worth. It proved to have be

I am working on an application requiring removing BGAs from a board coated with parylene. These BGAs have low standoff with less than 0.015" after SMT soldering. Can some comment on a reliable and consistent process to perform such rework? given tha

If you are looking for someone to coat these assemblies. I would welcome this oppurtunity to quote or even coat one as a first article (free of charge or course). As we are a coating house that uses all types of coatings as well as performing Parylen

To perform conformal coating of PCBs in high power electronics applications follow IPC-A-600F and IPC-CC-830B conformal coating standards. This standard enlists several performance criteria. Additionally, this standard is considered as a good referen

Can you share some information relative to these questions about your conformal coating process: 1) What process controls do you use for conformal coating? 2) Do you perform manual conformal coating inspection? 3) Do you use AOI for inspecting confor
