thanks for the opinion, dun think we want to drill the machine tables, due to SMT line config : 1) printer, 1unit machine 2) chip shooters, 3 units machine 3) IC mounter, 1 unit machine plus the potential void of machine warranty by the drilling,

Had a similar problem on a high speed drilling machine. It took 1 month before I found it. In the leadscrew ball nut, there was a guide tube which the balls circulate through. at the end of the tube is a shaped lip. This lip was damaged and the balls

Are your PCB's stretched or is it that the films that were used to make your PCB's distorted.Thus vias and TH's don't align. These things will probably be picked up in bare board testing , but depending on the amount of offset may get through, to yo

I have seen BEC holes drilled wrong also. On a couple of products We run, We insert a Pem Nut. The insertion hole is too large for BEC to read. So We have the board house drill a small hole for each array, circuit. If these smaller holes are drilled
