Scanning Acoustic Microscopy SAM, Acoustic Micro Imaging (AMI) Equipment Overview
Produced by a leading developer and manufacturer of scanning acoustic microscopes and complex wafer acoustic micro imaging systems, LPR Global’s scanning acoustic microscopes are used to conduct acoustic microscopy and acoustic micro imaging inspections. Developed with fast processing time and high-quality imaging goals in mind, we offer reliable NDT equipment for quality control and failure analysis of multi-layered electronic, microelectronic, aerospace, advanced materials, and life science components.
The Fast Scanning Acoustic Microscopes (FSAM) and Traditional Scanning Acoustic Microscopes (TSAM) feature a user-friendly interface, precise focusing features, and more data gates to easily check for cracks, inclusions, voids, and density variations in semiconductor wafers and advanced components at a wide range of transducer frequencies from 5 to 300 MHz.
Different types of analysis are available in high-speed SAM, including A-scans, B-scans, and C-scans.
Our equipment uses a wide range of transducer frequencies, from 5 to 300 MHz; with low flexibility providing higher material penetration; with higher frequency transducers, such as 200 and 300 MHz, allowing higher image resolution useful once a particular area of the material sample has been isolated.
Our equipment combines high-quality imaging with simple analysis, allowing users to capture high-quality fully-focused images of various types of samples.
