Entegris has created a family of materials with impedances that step down from 13 Mrayls to 3 Mrayls, allowing for minimal internal reflection and interference, and maximum delivery of energy to the test subject. This in turn enables increased resolution of internal features. Images that were once fuzzy and nondescript, become crisp and detailed, providing greater diagnostic value.
Where some suppliers have offered matching materials with impregnations and unknown properties, our POCO® facility has focused in on supplying materials with tightly controlled ultrasonic transmission. By offering a narrower band of impedance, we provide manufacturers certainty in the yields they will achieve as test heads make their way through the high value adding assembly processes. Higher yields ensure minimum manufacturing disruption and optimal product flow.
Customers can receive an acoustically qualified matching layer, machined to their specification. Our precision slicing and precision grinding capabilities enable us to provide anything from a blank to a finished matching layer.
