• Product Description
    ECM the assembly is easy. Stable production advantages compared to the microphone during a long time and replacing them a product.
    Type of ECM is classified as a normal Type and SMD Type. Developed by ECM Chip Type PCB Type is easy to manufacture,
    and to produce an ECM at a reasonable price. It is the ECM Module.
    ECM Module is not affected by the moisture and RFNoise which was a problem in the ECM Chip.
    So compared to the MEMS microphone for high prices, low price affordable mobile phone application market,
    the market expansion of ECM Module is expected.
