电子行业的全自动超声波清洗机应用

电子行业的全自动超声波清洗机应用

PCB板的清洗。我国电子行业中,绝大多数企业都在使用PCB,PCB组件焊接采用的助焊剂分为水溶型、松香型和免清洗型三类,使用较多的为前两种,多采用超声波清洗(也有不少是采用酒精刷洗),免清洗型原则上应该不清洗,但是,目前世界各国的大多数厂家即使采用免清洗型焊剂焊接组件,仍需要清洗。特别是高密度PCB以及高密度IC出脚不清洗或不采用超声波清洗,必将导致高密度线路之间和IC出脚之间吸附尘埃,一旦环境湿度大,极易发生高密度线间和脚间短路而出现故障,而一旦环境干燥,短路故障又自行消失,这类故障又不易查找。所以世界各国的电子整机厂均坚持对PCB板作超声波清洗。在我国,军工电子整机厂已开始推广,并收到了因此举既提高了产品可靠性,又降低了售后服务成本的双重效益。纳美清洗在电子行业清洗的开发应用中一直处于行业前列。

Cleaning of PCB plate. The electronic industry, the vast majority of enterprises in the use of PCB, the flux PCB components welded by divided into water soluble, rosin and free cleaning type three kinds, the use of more for the former two, using ultrasonic cleaning (there is a lot of using alcohol scrub), free cleaning type it should no cleaning, however, most manufacturers of the world even with no clean type flux welding assembly, still need to be cleaned. Especially in the high density PCB and high density IC feet without cleaning or not by ultrasonic cleaning, will cause between the high density line and between IC feet dust absorption, once the environmental humidity is big, prone to high density line and feet short circuit fault occurs, and once the dry environment, short circuit fault and disappear, this kind of fault is not easy to find. So the world's electronic factory have insisted for ultrasonic cleaning on the PCB board. In China, the military electronic equipment factory has been extended, and received as this can improve the reliability of products, but also reduce the double benefit of after sale service cost. Development and application of dynamic cleaning in electronic industry cleaning has been at the forefront of the industry.

接插件、连接件、转接器等器件的生产中,电镀和组装前也必须清洗,否则吸附在这些组装零件上的灰尘、油污必将影响其导电和绝缘性能,特别是一些复杂的多芯连接器尤其如此。

Connector, connector, adaptor device production, electroplating and before the assembly must be clean, otherwise the dust absorption, in these parts of the oil will influence the conductive and insulating performance, especially some complex multi pin connector.

电子材料加工成型后的清洗。如晶片、硅片、压电陶瓷片等电子材料是供给元器件厂家的产品,其产品出厂前必须清洗,特别是作出口业务的厂家,其产品清洗成为一大难题,超声波清洗是最有效的途径。

Cleaning electronic material processing molding after. Such as wafer, wafer, piezoelectric ceramic piece and other electronic materials supply components manufacturers of products, the product the factory before cleaning, in particular to make export manufacturers, their products cleaning has become a major problem, ultrasonic cleaning is the most effective way.

电子元器件的基体清洗。电子元器件的基体是由半导体材料制成并封装在金属或塑料壳座中形成的,在封装前,不但对壳座必须清洗,而且也必须对基体进行清洗,如IC芯片、电阻、晶体、半导体、原膜电路等。

Substrate cleaning electronic components. The matrix of electronic components are made of semiconductor materials and packaged in metal or plastic shell seat in the form, before packaging, not only on the shell seat must be cleaned, but also must be cleaned on the matrix, such as IC chips, resistance, crystal, semiconductor, original film circuit etc..
