(一) 简介超声波清洗在半导体工业和其他金属清洗上已广泛应用,它是把去污剂及水的混合溶液置于超声波清洗槽中,然后把工作件放入槽内,借助超声波发生器,发出可调节的超声波振荡频率进行清洗。工件中的污物经过去污剂及超声波的作用,失去粘着力而脱落于槽内,达到理想的清洗效果。但是它不象汽油那样属于绝缘电阻无穷大的湿洗工艺,而是属于一种绝缘电阻等于零的湿洗工艺。因此,对于绝缘电阻要求高的电器元件来说,无疑是一种
(A) Introduction Ultrasonic cleaning in the semiconductor industry and other metal cleaning has been widely used, it is the detergent and water mixed solution placed in the ultrasonic cleaning tank, and then the work piece into the tank, with the aid of ultrasonic generator, Issue adjustable ultrasonic oscillation frequency for cleaning. The dirt in the workpiece after detergent and ultrasonic effect, loss of adhesion and fall off in the tank, to achieve the desired cleaning effect. But it does not belong to the same wet insulation process as gasoline, but belongs to a wet insulation process with a zero insulation resistance. Therefore, the high insulation resistance of electrical components is undoubtedly one
