Subject: Life assessment for thermally shocked product
Message:
My company has recently undertaken thermal shocking of a small (0.6" x 0.6") hybrid-like device. This involved 450 thermal cycles from -50C to +90C in 60 seconds with 30 minute temperature dwells at each extreme. The product was unpowered. Am I able to determine an estimate for the product's life based on the testing described above and if so how do I go about it? Thanks, Bob
