A process consists of much more than just thee machine. When developing a cause and effect diagram ffor the process, there are many parameters that fall outside the machine itself. There are Man, Machine, Methods, and Materials. Just monitoring th

Hi folks, thanks for all the tips. We have run our first batch of these flexi boards now. I had the PCB suppliers make me some 1.6mm FR4 carriers to lay the boards on to carry them through the process. (1 flat & 1 with cutouts for the second side)

Hello Paul, Without all of the specific details of your product I would recommend providing the BOMs and samples to a couple of vendors and have them prove their capabilities. The Siplace platform is a solid platform for your application and the ap

Hello Phil, sorry for the confusion, because of our level of defect control and tracking at each process step, we did not use AOI systems at the time. We had a manual inspection station after reflow, then ICT and Functional/Final test for each produc

We are also looking for AOI machines, pre- and post-reflow. We already tried one machine from the UK (I don't remember the name, I perfer to forget we ever had it) and they told is it would do everything we wanted. Maybe so, but not well enough. It s

We've had much trouble with flex circuits. As previously mentioned, you must have local fids for the board or the BGA itself (if panelized). Other troubles we experience are drilled holes for pinned connectors. Unless the PCB manufactur has some w

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

Look into a used Siemens F-4 or F-5. These machines can be had for a reasonable cost, they are easy to maintain, the footprint is small (7' X 7.5') and they are simple to program. These machines have a 12 nozzle "Star" revolving placement head for
