In acoustic microscopy, resolution and inspection depth is an inversely related parameter that depends on the probe frequency and the characteristics of the involved materials. Therefore, the inspection frequency must be carefully selected in order to optimize the accuracy without decreasing the inspection depth below the specimen thickness. Suitable selection of the inspection parameters provides: Detection of ultra-thin (submicrometric) delamination in multilayer systems. Micrometric lateral resolution. In acoustic microscopy, resolution and inspection depth is an inversely related parameter that depends on the probe frequency and the characteristics of the involved materials.

This test is performed to verify the structural quality of the glassivation layer in aluminum metalized semiconductor devices or microcircuits. The glassivation layer is a deposited dielectric film (e.g., CVD, sputtered of electron beam evaporated glass or nitride, etc.) and its good condition is essential to avoid such problems as electromigration.

A comparison between Red Plague screening methods

Red Plague is problematic corrosion appearing on silver-plated copper conductors. An electromechanical reaction is induced between copper core and silver plating of the conductor (by means of moisture and oxygen present in the silver-copper interface). Wire affected by Red Plague is mechanically compromised, increasing the failure risk linked to severe vibration and shock conditions on space flight.
