How Hardware Startups Use Acoustic Microscopy for Hidden Defects
In this episode, Lucas and Luna explore scanning acoustic microscopy (SAM), a non-destructive testing method that hardware startups can use to detect delamination, cracks, and voids inside sealed components. Lucas explains how SAM uses high-frequency ultrasound to image internal structures—similar to an ultrasound for electronics—and why it caught on in the automotive industry after a 2018 Toyota recall linked to cracked solder joints in engine control units. They walk through a real example: a startup making waterproof smartwatches found micro-delamination in their potting compound using…
