Generally, our approach for defects finding is to ensure customers’ samples are kept intact of the original form and status. Non-destructive analysis technique(NDT) is deployed at this stage to find out what is wrong internally without cutting and opening the sample.

Confocal Scanning Acoustic Microscopy (CSAM) is a rapid and reliable NDT. It uses ultrasonic waves to detect changes in acoustic impedance within the testing samples. With reflective as well as through-scan capabilities, our CSAM is able to examine various materials, different sizes and particularly on samples with interior voids or delamination.
