用于铝线超声波焊线使用。用邦定焊接工艺，由钨钢材料研制而成，焊接对像主要是邦定铝线,是精密线路板后道工序（COB）焊接的键合材料。其主要应用于数码管、点阵、集成电路软封装、厚模集成电路、晶体管等半导体器件内引线的焊接。

Used for the use of aluminium wire ultrasonic welding line. The welding process is made of tungsten steel, which is the bonding material of the process (COB) welding of precision circuit board (COB). It is mainly used in digital tube, dot matrix, integrated circuit soft packaging, thick mode integrated circuit, transistor and other semiconductor devices.
