We are using a Panasonic MPAV2 to place some QFP's. Can someone please help me with a problem we are having with coplanarity! The machine is "dropping" parts due to coplanarity issues. What settings should we be looking at in order to eliminate the

I know that there is an IPC spec. for board pad size design for BGA components. After a little research we have found that recommendations vary from component manufacturers to board houses. (These recommendations are different than what IPC says....

Thank you for your reply. Answer: Auditor came to my company and said that we needed a solder deposition tester. The reason was that we had no real way of assuring that our solder process was repeatable. He referred to several IPC standards that mad

How could you know if your printing process is capable or in control if you don't have a print measurement tool? Still, I suspect it's a myth that 60% of SMT defects are screening defects. Are there data behind these figures or do we just continue

Dave, Yes the process is in control or that part that we can control. Visual inspection on first boards and then after a batch. I have had good prints with our current printing machines. My operators are very conscious of there work. Quality control

Don�t your recent findings on soldering defects point towards less need for AOI? Besides that, I imagine that with 100% control and having only good prints being processed while the bad ones getting washed and reprint you will see this magical 0%. Sh

The idea that AOI is not needed on your production line is like running a marathon without training before hand.You can only expect to get out of any given situations the amount from which you put in.Without some way of monitoring your process..How c

Hi Everyone, I am currently looking for a simple testing setup procedure to conduct solderability test in my small lab. Just wonder if anyone has any idea what kinds of equipment or preparation I need to get started. Any input like what website to g
