    PRODUCT PK

    PK图1 PK图2

    ASEMI adopts 50mil high-quality large chip, with good parameter consistency and stable and efficient output

    Inferior chip easy to heat seriously after long-time working , and will damaged the machine

    DB157 PK 打1 DB157 PK 打2

    ASEMI uses laser marking is not easy to fade and prevents refurbishment

    Inferior and easy to fade will pullute PCB board,and also exist a problem of malicious renovation

    DB157 PK 脚1 DB157 缩3

    ASEMI uses high-purity oxygen-free copper frame and pins, with good electrical conductivity and high strength of thickened pins

    Ordinary steel is easy to be oxidize and virtual weld, the strength is low then easy to break

    MB6S PK7 MB6S PK8

    The ASEMI factory uses Jianding and Guankui high-precision equipment to test 18 key electrical data simultaneously

    Other equipment has low precision, the electrical parameter detection is not strict, and the quality consistency is poor
