Currently use Hysol TS300 latex mask and need to explore alternative methods of drying the mask. The mask is applied with a Asymtek Century Dispenser and placed on drying shelves. Air dry is dependent on temperature/humidity. Tried all the UV masks o

Tape test to check adhesion and multiple point thickness test - each board has 5 points per side documented for thickness testing & we measure pre & post coating thickness with an electronic meter. Also temp & humidty are also logged, and alarms go o

Ya know a little clear RTV around the feet of your conveyors will keep them from moving when Bubba the Quality Director needs to take a load off and leans against it. And if you ever need to move them later, just cut around the base with a box cutter

I have several circuit boards (about 14" by 16" in size) that I recently acquired and am trying to repair. One problem is that the former owner painted (spray paint I think) the word "TEST" in big red letters covering most of the solder side of the

Techspray makes a liquid called "Eco-Stencil SMT Stencil Cleaner" and also pre-saturated wipes by the same name. We spray the cleaner on the stencil and then use the wipes to clean the paste off of the stencil. Putting 1 wipe in each hand and rub

I tend to get issue on and off with the feeders either stalling and/or running slow/noisy. They are actually pretty easy to clean and maintain. If you take off the side panel of the feeder you will see a few gears, belts and a motor. The first thin
