  • Copper-aluminum

    Copper-aluminum transition sheets are mainly used in the automotive electronics and power electronics fields as a transitional connection between aluminum-based semiconductor circuits and PCBs. Aluminum wire is a commonly used bonding material in chip bonding. The copper-aluminum transition piece can avoid the reliability problem caused by direct contact of the bonding aluminum wire with the gold plating layer, and provides a flat surface for wedge bonding. Most of the solder in the aluminum and electronics industries does not wet, and copper is a solderable metal that makes copper-aluminum transition sheets easy to solder on PCB pads.[more]

  • 铜铝过渡片

    铜铝过渡片是一种铜铝复合材料。铜铝过渡片不仅具有铜的导电、导热率高、接触电阻低和外表美观等优点,也具有铝的质轻、耐腐蚀、经济等优点。铜铝过渡片的铝面用于楔形键合,而铜面则为焊接面。铜铝过渡片作为楔形键合的过渡材料得到广泛应用[more]
