Ron, I'd agree that that sounds high. Some things that may be contributing to it: Volume. lower build quantity often leads to higher placement costs. NRE. Does this website quote an NRE for solder stencils, machine programming, and reflow profili

We keep seeing a problem with the plastic tool tip on an A12 tool being sliced off. I think it is hitting the edge of the tape separator clip assembly - I determined this by coating the tip in paint and then finding where the tip had struck the meta

Yes that sounds worth a look - thanks. I am also wondering if there is a thermal issue - we had 27 degrees in here yesterday and I remember the Mydata guy telling me to put a desk fan onto the card frame in the summer. I did this last year - when I

BEC hardware would be on the machine as a sensor underneath the placement table, to the left of the C&C, and an emitter attached to a bracket to the left of the insert head. The two line up with each other and the sensor uses a quadrant layout to det
