    DESCRIPTION

    HER308 详解-1
    HER308 详解-2
    SILKSCREEN PRINTER

    silkscreen marking is not easy to fade, to solve the ink screen printing easy fade

    high production efficiency of silkscreen marking, short delivery time, solve the problem of long delivery time and low efficiency of ink printing

    PLASTIC PACKAGING

    disposable injection molding with epoxy resin material

    good flame retardant performance, high strength, high temperature resistance

    OXYGEN-FREE COPPER PINS

    oxygen free copper, good electrical conductivity

    pin thickening design, thickness up to 1.3mm, can work for a long time without heating

    the LOGO of the original "ASEMI" brand

    A = advanced

    SEMI = semiconductor

    the figure shows the symbol of common cathod diode

    both ends are input current and the middle is output current in general

    there are two diodes integrated inside

    PRODUCT PK

    ASEMI DO PK 10 ASEMI DO PK 11

    ASEMI adopts 90mil high-quality large chip, with good parameter consistency and stable and efficient output

    Use inferior 80mil small chip,Inferior chip easy to heat after long-time working serious, and will damaged the machine

    HER308 PK-1 HER308 PK-2

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

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

    HER308 PK-3 HER308 PK-4

    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

    PK7 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
