I have searched through the topics here and none seem to address this specifically. I was wondering if anyone had any links/info directly showing how proper ventilation for fume extraction on a manufacturing floor should be handled. From my research

Well, I don't know if you want to muck around this much, but I bought a GE (Chinese made, of course) toaster oven with convection fan. Nice big glass door in front, you can use it in bake, broil, toast or convection oven mode. The only thing missin

I looked at a number of small bench-top batch ovens and saw two things. First, they got VERY expensive when you got above the very smallest units. Mine will fit an 8 x 12" board. I still have to do one that size and see how uniform the temperature

You will need to develop your reflow profile which includes drilling a hole through the fab and into the ball for accurate temp measure. During profile/process development you will probably want 3D x-ray (consider contracting that out). Once in prod

We don't have one of those cool air compressed syringes to dispense adhesive. We have to do it by hand. My question is does anyone have any suggestions on syringe size, needle size etc... for successful deposition of SMT adhesive? I know you can go s

How did I know senior was going to get in here too. Nice to see you again. I figured as much with the height difference, but I do not have the equipment here to test my thoughts. We somehow have our machine dialed in to run the 0201 parts with W
