  • METHOD FOR TESTING SIGNAL-TO-NOISE RATIO USING A FILM FRAME
    Publication number: 20180124534
    Abstract: A system and a method are provided for testing a MEMS microphone during manufacture by using a film to obstruct the acoustic ports of the microphone. The microphone testing is performed while the microphones are still in an array and mounted on a film frame. By performing the testing while the acoustic ports of the microphone are covered with film, unwanted, external noise is attenuated.
    Type: Application
