measure the board thickness before coat by a screw gauge, and then after, when the coating has fully cured. this works well for a single side coat. once your wet to dry thickness is down, you can spray to a particular thickness wet and be reasonably

There's a ton of em'. We used the one from Paul N. Gardner Company, part # WF-CCD. They cost 0.95 each, so if someone decides the gage looks better in their garage, it's not that big of a deal. We set up a program that puts down 4 stokes on a test

Hi Jimmy, We use flat belt exit conveyors. They are set-up to collect the boards and set off an alarm when the belt is full. This allows the boards to come out, but you don't have to pay someone to stand there and catch each board. Also eliminate

Hi, Can anyone suggest what solvents are the best for manual stencil cleaning?? we are currently using alcohol wipes, but the fine pitch apertures still have solder paste stuck in between them. We should ideallyhave a stencil cleaner, but until that

Be careful when using compressed air, it will not only �blast it all into the air you breathe�, it can also damage the stencil by bending the delicate land mass areas of fine-pitch apertures. I recommend the article �SMT Stencil Cleaning: A Decision

Which is the risk in soldering lead bearing components in a lead-free board with a lead-free paste? Is the reliability of the PWA seriously endangered or not? I have many lead-bearing components in my inventory and I don't know if I will be able to

Does it do nozzle changes at a different speed than the programs? It's been a while since I worked on these beasts. I"m wondering if it can handle slow speeds but at full bore it can't handle it. Maybe try one part with everything set to slow speed

Thanks Rob, I have samples and production quantities that we are running on leaded assemblies now. I guess my next question would be, if you are already building lead-free assemblies, how are you processing the electrolity and tantalum caps? The o
