I almost forgot; If the pcb have HASL (Non RoHS) surface finish, then big fine pitch QFP:s could be shifted during reflow, beacuse of the un-even pad-surface... We have been trough that scenario also... But step No.1 is to make sure that the componen

Go for Gen 2 NT feeders, the Gen 1 Feeders tend to be problematic the older they get whereas the Gen 2 feeders are a much better prospect. I've used 8, 12, 16, 24 and 44mm. Some problems to look out for is pull back of coverlay and removal of waste

Yes 0402 8X4 embossed feeders exist for Panasonic MSR, Universal GSM, Contact Systems, and Mimot for sure. In the old days of 0402 components, 0402 resistors used to come in 8X4 paper tape but now I think most 0402 resistors and capacitors come in 8

There is a spec I read that states +/- 0.001" (0.025mm) print deposition accuracy and repeatability is more than adequate for 0201-chip printing. I don't think any print studies where done for 01005 chips yet. There are several other factors besides

Hello, after we finish project (mydata) we unload tape from feeder and place a stick on the edge of tape. Maybe somebody can help with alternatives to this? (plastic clips) becouse then unloaded tape is used for another project it is sticky
