Microphone MEMS devices are becoming more and more important for state-of-the-art mobile communication applications. These applications require an expanded linear frequency range and usually need small packages, but at the same time they are very cost sensitive.
Mulltitest’s InPhone solution is based on an excitement in a pressure chamber that ensures homogenous acoustic stimuli across all parallel tested packages. The InCarrier® concept supports stable high-parallel test even for small packages. Therefore, this setup provides unique performance and cost-of-test advantages.
