Cheers Greg, It's unusual to have such direct access to manufacturers & their opinions. I'll tell you what really does get us, and splicing doesn't work well on these occaisions - big SMD connectors, requiring deep pocket feeders. You only get m

Installation/set up of the component shuttle is critical. The shuttle must be perfectly squared and leveled, since it has a 4 spindle pick/place head on it. This shuttle head can pick up to 4 comps. from the shuttle feeders (gang pick) and will deliv

Good day, 2D inspection requires correct adjustment. In the other case it will cause continuous problems and false alarms. Adjust the lightning first and choose the correct process limits second. Look at histogram when you are adjusting the camera

We are having a random problem with boards bowing significantly. Its a large through hole board with only one QFP on it. The bowing occurs during the SMT reflow. The only conclusion I can come to is a problem at the board house that made it. I just w

Your problem is not the 0.4 pitch. Your problem is the manual cleaning. Manual cleaning will only remove the solder paste from the surface of the stencil. What's more, manual cleaning will force additional contamination into the 0.4 pitch apertures

Hi, We just purchased the above two machines and they're still in the trial period. We have problems with air requirements of the above two machines. For example, Samsung CP45 is listed at 8 CFM only, but it will kick off the compressor (rated at

Hi folks, I had posted this earlier but I think there was some confusion on where the wrinkled joints were. The picture is the side view of a BGA soldered onto the PCB. I was able to take this picture becuase the BGA was at the edge of the board. I
