Mail*Link(r) SMTP FWD>PCB Grid Boards: Source? Hi Matt, Do they need to be plastic??? In our printed board manufacturing facility, we had the same problem, for boards in the range of 3-6 mm (0.125-0.25 inch) for both "racking storage" in the manufacturing facility and for "baking" for solder resist and screen printed markings. In our processing, we leave the printed boards "panelized" until just prior to final inspection. We designed and fabricated our own set of metal racks. Because our Electronics Manufacturing Group is a "full-service" electronics packaging facility, we have our own N/C sheet metal punching capability. We punched a series of what's called obround holes (a rectangular hole with full radius ends) to punch out the holes on the desired board pitch, then we did two right angle bends and we had a channel-like structure for supporting the boards. The following is a crude drawing of the holder. _______________________________________________ _________ | | | | |___________ _________| As long as ___________) | | (_________ | | you need/ |___________ | | _________| ___________) (_________ Want | | | | |_ _ _ _ _ _ _ _ __ _ __ _ _ _ _ _ _ _ _ _ _ _ |__________ |<--~18 mm->| | About 50 mm | | Less than | | the width of | | the PB | 90 degree fold ->|------------->| lines If marring of the board surfaces is a concern, we placed two layers of a clear heat shrinkable sleeving around the "tangs" between the slots to provide a "cushoned" non-marring surface. Hope this helps in case if nobody else has a possible source, you might consider fabricating you own.

These are plastic waffle boards with grooves used to stand up individual circuits. We have a source for grid boards with 0.070" slot widths, but need something wider for other parts. There is only the one part available from our existing source. I am looking for something that has a width of about 0.150". I don't think that I can be too choosy about the slot width, as long as it is at least 0.135" Matt Byrne From: [log in to unmask] ------------------ RFC822 Header Follows ------------------ Received: by quickmail.llnl.gov with SMTP;28 Aug 1996 10:48:16 -0700 Received: from ipc.org by simon.ipc.org via SMTP (940816.SGI.8.6.9/940406.SGI) id MAA05927; Wed, 28 Aug 1996 12:37:10 -0700 Resent-Date: Wed, 28 Aug 1996 12:37:10 -0700 Received: by ipc.org (Smail3.1.28.1 #2) id m0uvnfw-0000TIC; Wed, 28 Aug 96 11:41 CDT Resent-Sender: [log in to unmask] Old-Return-Path: <[log in to unmask]> Date: Wed, 28 Aug 96 12:43:31 EST Message-Id: <[log in to unmask]> To: [log in to unmask] Subject: PCB Grid Boards: Source?
