Since I have posted on this last, we have found that 99% of our nozzle sticking problems are do to part height problems. I have been told that CP6 machines are very sensitive to part height do to the amount of spring travel in the nozzle. If you hav

I do not mean big, heavy transformers but rather small ferrite core transformers, with ferrites in the range of EF16 .. EF40. The weight of the lead and its percentage of the total weight is not the issue here. We simply do not want lead-containing t

All good points and thank you for your replies. Most of the components lost are discretes. The problem I have is my operators gather any SOIC "lost components" and return them to stores in a small metallised bag. This in turn goes into a 16" X 12" X

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, I think the comment about the board height is because the MYDATA checks the board height each time it loads a tool so this is eliminated from being an issue because the machine knows the PCB height. I don't think it's so much what height the PCB
