Richard - Basically, yes, though you may want to throw in a fudge factor to assuage your caution/due diligence monkey.
FYI: The Maximum Operating Temperature (this is a normal operating condition temperature) for a PWB is based on accelerated aging testing, and comparing "as received" performance parameters of the etched laminate with those after aging. Regards, Peter L. Tarver, PE ptar...@nortelnetworks.com -----Original Message----- From: wo...@sensormatic.com [mailto:wo...@sensormatic.com] When a PCB is rated 105C or 130C or whatever, what does that really mean? Can I really operate a 130C rated board at a maximum surface temperature of 130C for years without being concerned about reliability or safety? Is there a relationship between de-rating and reliability or safety? Richard Woods
