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...
Non-destructive detection of micrometric internal features within EEE microelectronic systems.
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.
Acoustic Inspection of Hybrid Systems on Laminated Substrates
Hybrid microelectronics within plastic packages are comprehensively inspected thanks to the con-focal resolution provided by the scanning acoustic microscopy technique.
Water ingress through delaminated parts in plastic encapsulated systems
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.
Confocal Acoustic Inspection of Optoelectronic Components
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...
Inspection of thick EEE plastic encapsulated parts
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 internal inspection of EEE parts and passive components
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...
Scanning acoustic microscopy (SAM), also denominated acoustic micro imaging (AMI) and scanning acoustic tomography (SAT), is a consolidated and recognized tool for non-destructive quality control, inspection and failure analysis in microelectronics components and materials...
