Greetings and Hallucinations, Perhaps it isn't the X-rays but the strong EM field the X-ray machine is generating that could be causing the trouble? I know we used to kill credit cards in the ole physics lab with some of the coils we used. This is a blind guess.

Mario I agree with Dave,, check out for yourself if the data is getting corrupted. I worked for a company a few years ago were we had a similar problem with EEPROMS we would send to customers for program upgrades. The customer would get them and they wouldn't function. Verifying the programs would show that the data was corrupted. The same thing would happen with UV- erasable EPLDs. As a test we ran many samples of programmed devices through our Circuit Scan machine with no effect but when run through the Airport's Machines we did have some random failures. The manufacture couldn't explain it. We started packaging spares in a heavier silver ESD packaging and the problem mysteriously went away. We never had a problem with completely assembled units, possibly because they were in metal cabinets. I don't know if this helps at all but good luck Hope you solve the problem. ---------------------------------------------------------------------------- ----- 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 ---------------------------------------------------------------------------- ----- --------------------------------------------------------------------------------- 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 ---------------------------------------------------------------------------------
