Hello, I need an advice regarding the next issue: in the case of Assembleon Topaz or Emerald SMT machines, is there necessary to teach first the block repeat coordinates and after that the PCB fiducial coordinates when you do not have these coordina

I rarely use blk fiducials. But when I do, they are always programmed after the fids. It's the fids that sets your general alignment of the panel. I only use blk fidus for thin pcbs (30 mil) that tend to warp when on the conveyor.

With 0402 components becoming more common today outside of the telecommunications industry, our company is qualifying equipment and processes for an upcoming product incorporating 0402s. Having used 0402s in a previous position, I am planning a DOE o

My steps are different in that case: 1- Check mounts. Try to adjust origin point until get the pretty good mount positions. 2- Teach fiducials ( Board fids, not panel fids) 3- Use fids, check mount again. 4- If OK, then teach Block Repeat. This alwas

We recently acquired used MPM Accuflex. Immediately I noticed the live vision is mirrored. This makes it incredibly difficult to teach fiducials. I noticed some smudges on the lens, which leads me to believe the camera assembly was "worked on" at som

this is the order that I use. 1. Teach pcb origin 2. Teach fiducial location 3. dial in vision on fid in mark info. 4. go into mount and verify that the primary image is on in x/y (after perfoming a teach trace condition) and then do any offsetts if

I chose a Vitronics XPM3i primarily for the AutoSet automatic profile generation feature. We are high mix and simply cannot profile every board. The AutoSet feature is quick, easy and we rely on it 100% and have great results. These ovens have had ve

Yes!!! How can we assemble boards with 20 pitch when we allow 0.008� error to the master art? Excellent question!!! IPC-D-300G has nothing to do with assembler requirements. It is written by and for fabricators, so that they can be comfortable.
