OK, I am really happy with the robustness of my CSM84. I wonder how hard it would be to hack up one of these 3-phase machines to run off single-phase power? Mostly, it just feeds a big DC supply for the X-Y servos. 2 heads with ANE should be just FI

Want to update this question a little, I know it appears few years ago, but I hope there is some updates... We have to assembly few samples of motherboards with this kind of finish (customer mistake during pcb order). Normally we can use leaded sold

Yes, we can't use pure Pb PROCESS. And as I say we will not use it anyway, as we have lead-free BGA's, LGAs, component with Solder Charged Terminations... It's became almost normal practice to solder it with leaded solder pastes. In this case peak re

I might need some help to explain what I'm seeing here. The first 3 look like before pictures. They seem ok. The last 3 look like after pictures. It doesn't look like fracturing joints as would be a normal failure for vibration test, more like it rea

What I would look at is the chemicals being used in the facility where the complaints are. Flux/flux gel, IPA, cleaning agents, etc. Perhaps you should limit the usage to certain people only, who would be trained how to properly use these. Something

Gyver: Lemme take a wack [if you�ll excuse the expression, given direction of the later discussion] at your questions. Q1. Will the baking of BGA or PCB cause more oxidation before the SMT process? A1. It certainly will not cause less oxidation,
