摘要
通过改进软钎焊材料的挤压模具,使其具有排气和排油功能,减少产品夹杂气体、裹油起皮(或毛刺)等缺陷,延长模具的使用寿命。模具改进的结果表明,挤压熔点在300℃以下的软钎焊材料时,其效果较佳。
By improving extruding die for soft soldering materials with air＆oil discharging function, product defects were reduced, and the operation life of die was extended. The test results indicated that, the improved mold had better performance for extruding the soft solders with melting point of 300 ℃ and the below.
