Package crack/void between non-connected terminals is a critical anomaly in plastic encapsulated parts. This is so as these can turn into a conductive path and lead to catastrophic failures. In this regard, Scanning Acoustic Microscopy (SAM) is the most effective non-destructive...

Micrometric-wide internal features of sub-micrometric thickness can be easily detected in our recently upgraded instrument. The high lateral resolution is within the current state of the start in the non-destructive inspection of deeply embedded objects.

Hybrid microelectronics within plastic packages are comprehensively inspected thanks to the con-focal resolution provided by the scanning acoustic microscopy technique.

High-current low dropout regulator encapsulated in a TO-263 package is inspected by confocal scanning acoustic microscopy (C-SAM). Probe frequency and inspection procedure is adapted to the internal structure of this plastic encapsulated microelectronic part.

An Infra-red led emitter is inspected by scanning acoustic microscopy. Probe frequency is adapted to the characteristics of the system. In this case, considering the large thickness of the package a 50 MHz transducer is used. Our phase inversion algorithm identifies and...

High-resolution inspection of plastic encapsulated systems with complex internal architectures requires of confocal imaging techniques to block out-of-focus features that otherwise impair the resolution and the image quality.

Non-destructive testing methods are critical for the screening, inspection and failure analysis of plastic encapsulated and other EEE systems. Typical non-destructive testing activities involving EEE parts are grouped in three main categories: • Functional inspection (electrical...
