Umar, We don't think you've violated ESD handling in the manner you've described. If your employees were wearing foot straps, and your floors are conductive/grounded. I've run into this at multiple companies, where transporting the PCBs station

We use Photondynamics SV-7550 now. We want to upgrade our AOI because we found that SV-7550 are not very good to detect solder defects. I send samples boards at each company with the solder defects that i can't detect with my Photondynamics SV-7550.

Hi Derek, just curious of one thing - are the vias within the BGA's the only vias covered or are all vias on the board covered. Just trying to figure out what is making this area different from the rest of the board. Regarding leaching, I do not be

We are running SMT products and have been for some time now. First, I wanted to check with you folks to see what an acceptable FPY rate, or what you would consider and acceptable rate, is. Secondly, we are having issues primarily with product that

I have 7yrs experience with JUKI's and I liked 2000 series(2050,2060) dont get caught up in the 730 or 760 these machines are obsolete or at least on there way and spare parts are hard to come buy. The 2060 is the chip shooter. I like the user friend

Hi again Bobpan, One thing I noticed when I pulled the z-rod to inspect it was that it was "bearly" finger tight. When I replaced it, I snugged it a bit better (not overtightening). After resuming setting up additioanl placements (this board requires

The 3-Tier PCB library concept was originally created by IEC (International Electromechanical Commission) in 1999 and introduced to IPC in 2000. The concept had to be created as a solution for high density packaging for hand held devices to ruggedize

Assuming that you have a saturated moisture-sensitive component: At what temperature would popcorning or internal component damage occur? I would guess that it would be at a temperature where water would boil, around 100 degrees? However, the JEDEC J
