It was found that metallic elements were found after 168 h of Highly Accelerated Stress Testing (HAST). Moreover, result from the cross-section indicated that crack was found in the solder resist and both white and bronze powdery were found. With further elementary analysis of those different ...
The main drawback of THB is itslongduration, necessitating weeks before useable data are obtained. Because of this, an alternative test, theHAST, has been developed. HAST uses more severe stress conditions but can be completed in only 96 hours. Its shorter duration is an advantage that makes ...
