Patrick, Kathy and all others kinkdly requesting this and other articles, please observe the following: Please go to the SMTnet site and retrieve my article about the laboratory qualification requirements for boards, as well as many others there. I wrote most of them two years ago while serving time at Celestica. That would place them in the The Laboratory - A Primary Evaluation and Qualification Factor to Determine PCB Supplier Process Capabilities by Earl Moon - Proof Of Design (POD): http://www.smtnet.com/express/199907/. Note, there are others during this time for about 3 months Enjoy, Earl --------------------------------------------------------------------------------- Technet Mail List provided as a free service by IPC using LISTSERV 1.8d 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 delivery of Technet send the following message: SET Technet NOMAIL Search previous postings at: www.ipc.org > On-Line Resources & Databases > E-mail Archives Please visit IPC web site (http://www.ipc.org/html/forum.htm) for additional information, or contact Keach Sasamori at [log in to unmask] or 847-509-9700 ext.5315 ---------------------------------------------------------------------------------
