Hello, We are currently trying to design and ultimately implement a system that will be able to count and manage component placement for three Sanyo chipshooters on three SMT lines. As the number of components decreases in the reels we want to be ab

| We have successfully put .016" vias in .030" pads. | There is no issue with .030" solder balls, since | the actual volume of the .002" via in pad is small | compared to the ball+solder paste volume. | We did notice random bubbles where, apparentl

We have just go another batch of PCB's from our loaders, and some of the boards are severely warped. The boards are PCI cards and one of the boards is 9mm out at one end. The PCB is 210mm long and 4 layers. I am wondering if anyone knows what could

| I am looking for information on reflow temps for a flex board. There is only one 6 pin IC but the board has a 3M double sided tape. | Is it possible to reflow without damaging the tape. Any suggestions? Do you have a profiler for your reflow oven?
