Re: Stuffing boards with pulled QFP chips

My last run of P112 boards was 150 and I'm thinking of doing another 150 or maybe 200. Phew, I sure wouldn't want to hand solder 150 - 200 boards! Been there, done that, never want to do it again! There are machines that can do reasonable lead pitch spacing without vision, using mechanical alignment. My Philips CSM84 does 0.65mm lead pitch TQFPs quite well. One other detail is lead coplanarity. The leads from the manufacturer are formed AFTER plating to all sit on a flat surface. If the leads have varying solder thickness after removal, or are bent out of the seating plane by handling, that will also affect the ability to reflow solder them reliably. Jon

Hello AJ, Al, It took me a while, but I finally shipped the tapes to Raymond Stricklin. I also have SunOS 2.0 tapes: http://afterpeople.com/images/Image%20(30).tif http://afterpeople.com/images/Image%20(31).tif Al, check if these have been already images, if not I'll mail them to AJ.

Hi, Plamen & Al, I'm just catching up on some of these past threads involving QIC cartridges. What ever became of these Paragon tapes? Were you able to read them and archive the contents?
