QFN or MLFs are mainstream now, QFNs already evloved to much more complex versions now like matrix pins, stacked dice and flipchip versions. IPC 610D already includes them, just make sure the pins have solder plating, the PWB pads have soldermask in

I could use some help too. I have a bunch of SMD 4 Pads Inductors from Central Technologies. The dimensions of the part is 11.30x13.9x6.9 . I've called four companies already and none were able to find a carrier for this part. These parts are on plas

And pin outs of both. Once I saw a SOT-6 replaced with a miniSOT-6 (IIRC) The pin outs of the two parts were different. We did make an adaptor board and it wasn't too bad. We populated a panel of the adaptor boards, depanelized them and put them in t

Hold it!!! Call Bob over at Tri-Metal Fabricators and ask him to make you one for about 10% of the price a fine OEM would charge. Might not a a fancy anodized finish, but at the end of the day, it'll hold yer trays just fine.

Thanks for the explanation but we dont have a need for a JEDEC tray or matrix tray feeder. My volume is half million pieces a year so we are on the small side of the spectrum.

Hi, Why not have a look at Philips/Assembl�on, their ACM machine is quite nice. It may also bring you down to Flip Chip, 0201 some through hole and odd form placement. Nice options like bulk feeding, coplanarity tests, fluxing for FC, prom feeders (

that's a pretty cool idea, I like some thinking 'outside the box '! 1. I don't think picking it up and placing it will be much of a problem. once the rivet is placed it will be held in place by the paste. However, you would need to make a tray that
