Oh yeah, so we have a auger valve similar to that on one of our other machines that we use for dispensing SMT glue, and solder paste also. We have a conditioner that we flush it with at EOD when in use, then we just let it sit idle with the condition

Not sure exactly what kind of coverage your looking to get but we use Dow Corning 3-1944, it's room-temp cure and rather thick, (think warm honey). But we have found it useful on several projects. http://www.dowcorning.com/applications/search/produc

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

Hi folks, I have a conformal coating application where I need the coating to be UV stable for a number of years without any crazing or cracking of the coating. I have looked for such a coating and have come up empty handed. Much of the circuit boar

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

Is conformal coating necessary for products that are used indoors?

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

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

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
