Subject: First Year Multiplier
Can someone explain what the first year muliplier (per Bellcore) means and does each and every device/unit need to go through the burn-in time and temperature or can this be obtained by only running a qualification sample size at a burn-in temperature for the specific duration? If so, how big must the sample size be or is that defined anywhere?
