【摘要】 对电真空钎料溅散性的各种影响因素进行分析对比 .结果表明 ,影响电真空钎料溅散性的主要原因是原料中含有氧、回炉料中含有CuO和Cu2 O ;采用 2～ 3次高真空重熔是解决电真空器件用贵金属钎料溅散性问题的根本方法更多还原

【Abstract】 Different influence factors on the spatter property of the electronics vacuum filler metals have been analysed and contrasted.It has been shown that oxygen in the raw materials and CuO (Cu 2O) in the scrap are the main reasons.Two or Three times re melting under high vacuum is the basic way to solve the spatter problem.更多还原
