I'm glad you clarified that. I wouldn't want to end up in a pickerel.

Thanks Richard. I like your analogy, though when you mentioned it my thoughts ran to carp the boniest fish I have ever encountered. The fishbone diagram reference was not from me but from Ingemar Hernefjord. It is impressive.

And the IPC-HDBK-001 has Tables that used to be wishbone charts for individual processes, such as Table 7-4 (Common printing problems), Table 7-9 (VPS problems/solutions), etc, that could become individual branches on the fish. I think a lot of us are just waiting for the same answer as you; we would all love to see a wishbone chart by which we can trace back the possible cause for a given assembly or solder defect. But this particular wishbone chart, if it even exists, would have more individual bones than a Minnesota Northern Pike. ************************************** See what's free at http://www.aol.com. --------------------------------------------------- Technet Mail List provided as a service by IPC using LISTSERV 15.0 To unsubscribe, send a message to [log in to unmask] with following text in the BODY (NOT the subject field): SIGNOFF Technet To temporarily halt or (re-start) delivery of Technet send e-mail to [log in to unmask]: SET Technet NOMAIL or (MAIL) To receive ONE mailing per day of all the posts: send e-mail to [log in to unmask]: SET Technet Digest Search the archives of previous posts at: http://listserv.ipc.org/archives Please visit IPC web site http://www.ipc.org/contentpage.asp?Pageid=4.3.16 for additional information, or contact Keach Sasamori at [log in to unmask] or 847-615-7100 ext.2815 ----------------------------------------------------- --------------------------------------------------- Technet Mail List provided as a service by IPC using LISTSERV 15.0 To unsubscribe, send a message to [log in to unmask] with following text in the BODY (NOT the subject field): SIGNOFF Technet To temporarily halt or (re-start) delivery of Technet send e-mail to [log in to unmask]: SET Technet NOMAIL or (MAIL) To receive ONE mailing per day of all the posts: send e-mail to [log in to unmask]: SET Technet Digest Search the archives of previous posts at: http://listserv.ipc.org/archives Please visit IPC web site http://www.ipc.org/contentpage.asp?Pageid=4.3.16 for additional information, or contact Keach Sasamori at [log in to unmask] or 847-615-7100 ext.2815 -----------------------------------------------------
