I don't know how your printer could match the board's alignment to the stencil if they aren't. If you don't have fids on both board and stencil that match you'd have to use pads, but then you've got apertures thrown in to the mix. If that's the sit

you take the stencil which is contaminated with basically a toxic substance, add a solvent (alcohol) then use compressed air to blast it all into the air you breathe. I used to use foam wipes that were pretty good. I've also seen thick clothe ones t

What? That is easily done. With a 127 micron stencil thickness and apertures made for a QFP 0.5mm pitch... Remember from school of how You squeeze a media under a certain presure (like air), from a bigger diameter towards a smaller nozzle, You will i

"find yourself a good stencil manufacturer its there job really just tell them what machine you have and they should do the rest." I have to dissagree with this last statement on so many levels. There's a reason why it's called engineering. Plus,

Aperatures are often best decided by the stencil manufacturer principally because they would know what is easiest and best for there laser cutting machines, why would i dictate to them something that would not work well for there machines. but are yo

Haven't done any studies other than how clean can you get a stencil. I would clean 'em and inspect the apertures and see if you have any residues. If so, I would clean again the amount left would be so miniscule that I don't beleive it would cause

Hi guys: I'm trying to get the recommended pressure for stencil edges using air compression, I'm working with I-source but they don't have any standard like IPC or something that can help me to use and decrease the replacement of stencil because of

I have experienced the exact same problem with excess solder touching the plastic component body. The solution in my case was simply to replace the stencil. I was using a reusable stencil frame that had been worn out. I replaced the stencil with a so

I am a lay person researching the application of non-woven material in stencil rolls either using branded material or non-branded alternatives for DEK, MPM Panasonic machines in SMT environments. I have read a number of articles referring to aqueous
