Conformal coat material dispensed through epoxy needle?

Thanks for the tip. I'm still getting familiar with the machine by reading the manuals as I have time. Was wondering what type of solvent you use to clean the dispensing mechanism parts? Or do you not clean anything and simply dispose of the syring p

You should have no problem. We use a very dated Asymtek machine (Automove 303) retrofitted for dispensing, air over syringe. It took time and some tinkering with. But all things considered, we're able to achieve remarkable results. I would recommend

Dave, Few questions concerning your Umiseal 1B73. To cure your Acrylic coating do you respect specification ( 2Hrs-170degree F) or you go faster than that? What do you use to cure it? Do you have to clean your nozzles each day or each monday beca

Some UV cure coatings do not have the correct rheology for sticking to small sharp corners. 984 is one of them. MicroCoat Technologies, Allen, TX makes one that works every time.

We are looking at switching to UV cure for faster throughput. Does anyone know of any cost effective coating manufacturers? The pricing we are getting back are around $250.00 a gallon in 5 gal pails. This is more than twice what we pay for our curren

Normally, some conformal coatings do not have very good wetting properties, that should be basic function of a good coating material (the same reqirement as avoid bubbles during coating process)! For UV curing conformal coatings, you can try Lackwe

So I had the same question too when I was setting ours up. My lazy (and cheap) solution was: for each program I have a universal path that is used up to the first dispense instruction and after the last one then I covered the surfaces underneath tha

Un-cured conformal coating

Electrochemical migration under conformal coating: That's possible. Very few conformal coatings are water resistant. So, if you have ionic material on your board, standback. Uncured material under several IC: Materials like yours need moisture fro

The environment essentially defines the need for coating. "Inside" may mean inside a men's locker room with attendant high humidity or inside a climate-controlled clean environment. Conformal coatings offer protection against moisture, fungus, chemi
