This is the dilema during this transition period. Here is a tip: If you see typcial solder joints on a lead free process, but only on one component type....it probably has a significant quantity of lead in it (ex. Sn90/Pb10...and so on) If using T

I wouldn't worry about patents except for those types of feeders which have patents such as the MyData Agilis feeders. I would worry about cost of tooling for $tampings. Long time for ROI there. Also pay attention to the burr side and shear side of

Fastek will get it done with 2 machine and 2 shifts. 2 shifts would need to place 50,000cph. One CP643 with both device tables set could get it done. Having it panelized in 50's, you would need to print 50 panels a hour so get a auto cleaner on the p

I assumed a conservative 25,000 cph for each of the chipshooters...whether it's an MV2F, CP-6, CP-642 etc. You're not going to get 50,000 cph out of (1) CP-643. You might for short periods but not in the long run. It would be suicide to rely on one

Hey Peter, Did some simple math... 800.000PCB's x 20cmp = 1.6million placements 8hrs/day * 22 days/month = 176 hrs You're looking at over 90kCph fulltime! I'd say go with an AX-5 as JAX suggested. Given the product you described you could reach s
