Didn't know that outfit, thanks for the link. :) Would you say they are durable enough to say 5 boards with it? (I would hope so, but you never know...)
With regard to the delivery of the fine pitch stuff ... as long as the one putting together the kit is ordering those as cut-tape then that should be no problem. Just cut the tape into smaller strips and include those with the kit. regards, Fred ----- Original Message ---- From: Steve Wiseman <[email protected]> To: Discussion of precise time and frequency measurement <[email protected]> Sent: Sat, March 26, 2011 3:10:13 PM Subject: Re: [time-nuts] Parts Selection - Short Run Assembly On 26/03/2011, Bob Camp <[email protected]> wrote: > Best bet - get / make a simple screen printer.

Works fine, for low volume, and is easily capable of 0.5mm pitch. More of a concern, if issuing kits of parts, is how to deliver fine-pitch QFPs with their legs intact. The best way to package them for shipping may well be to attach them to a PCB with some kind of melted metal... (This is probably my first post here.
