HOW TO TEST IGBT WITH SAT(SCANNING ACOUSTIC TOMOGRAPHY)

Introduction What is scanning acoustic microscope? A Scanning Acoustic Microscope (SAM) is a nondestructive testing technology that employs highfrequency sound waves to inspect the internal structure and defects of materials. It is especially suitable for quality control and failure analysis of electronic components such as semiconductor dev

NDT (Non-Destructive Testing) and UT (Ultrasonic Testing) are two different testing technologies that are both related to materials quality control, although they have differences and connections in terms of principles, methods, and applications. Definitions and Basic Principles NDT (Non-Destructive Testing): Refers to a range of techniques
