Subject: Aging factor / electronic ship
I'd like to have some informations about aging tests on electronic ship as ASIC. In fact I want to know if it's better to consider an aging with temperature or with frequency. With temperature as aging parameter, it's difficult for me to solve the arrhénius equation because i have no idea of the ship energy activation. where can i find such an information. My problem is in fact to determine the aging factor in order to be able later to correlate the test results with reality. Can frequency that pilots the ship be a good aging parameter ? if frequency is multiplied by two, is that meaning that the ship lifetime is divided by 2? if somebody has some informations about this, thank you very much ! Bye, Katell
