We've used both 1A33 urethane and 1B31 acrylic coating on our SMT assemblies with great success for many many years. This is with components of all shapes and sizes including a 9 ball micro-BGA. We apply the coating in every way imaginable and we hav

I have seen a configuration with a lows type blacklight mounted inside of a smaller cardboard box/ depending on the size of your board, that may work.

Why not just pick up something like an old Camalot 1414 and use that? Then all the work other than rigging up a valve is already done. 1414s go for a couple or five grand in workable condition, especially without a pump.

I am looking for a machine to protect PCBs against moisture with varnish. It doesn't have to be very efficient, it seems that one for a desk is enough. What to look for? Is it worth looking for a used one? Best available in Europe.

I am looking for a reflective coating on PCB. I have designed a PCB with SMT type side LEDs and Top LEDs. The light from these LEDs fall on to a lens profile on top of these and get mangnified and reaches the dashboard instrument's pointers. I tried

We doubt that Humiseal 1A33 is causing opens in your assemblies. We'd guess the opens occur earlier in the process, but are not hard failures. So, you pass your tests. When applied, the conformal coat flows into the gap in the ball crack and insulate

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

I built one using an old Asymtek Automove. When all was said and done, it cost less than $400, including what was paid for the machine itself. It's a very basic setup, (air over syringe), but for our needs it does everything and more. With air to syr

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

There are factors that manufacturers have taken into consideration when dealing with coating. On/off times, dispense speeds, heights, etc.. Dedicated software with tools to easily map out paths are a godsend. We made our own coating machine with a s
