It sounds like they are referring to Low-Pressure molding, which was designed specifically to encapsulate electronics. I have seen some products that were processed on polymide flex, and then overmolded in this process. I would start by contacting "

Hi all. I used a 5/16" white paper sticker to mark a reject PCB in a panel of 10. One of my my Quad 4Cs sees it O.K. and marks the PCBs reject. The other machine either shows them all reject or shows the marked one as good and the other 9 as rejec

I agree with everyone else here, 3-6 months for blowing dust out of panel a bit excessive, once per year will be fine in most environments. If you find it needs to be more frequent, you need to explorer dust preventative measures. (Check panel seal,

Hey everyone, Our company just picked up a Quad IV C/115 pick-&-place system from one of our offices that closed, but we do not have the documentation for it. It looks to be a very old system so I can't find it anywhere online and we just don't know
