Neil: I ask you to look at your testing... You tested many boards in different ways... Did you test more than one board in the same way? How many did you test in the same way? Was there differences found when testing the same way? Were the different results found in the different ways of testing statisically significant when compared to differences found in testing the same way ...in other words, are you seeing different results because of different test methodology, or are you seeing noise? I ask these questions, because I have a suspicion that you may well be seeing noise, because I have trouble believing that the different methodologies gave significantly different results... But I have been wrong before...:-) Rudy Sedlak RD Chemical Company --------------------------------------------------- Technet Mail List provided as a service by IPC using LISTSERV 1.8e 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 847-509-9700 ext.5315 -----------------------------------------------------
