超聲波清洗機(jī)在電子行業(yè)中的清洗淺談

Ultrasonic cleaning machine for PCB board cleaning: In China's electronic work, most companies are using PCB, PCB components for welding flux selected into water-soluble, rosin-type and no-clean type, the use of more Two kinds of ultrasonic cleaning machines are used. The no-clean type should not be cleaned in principle. However, most manufacturers in the world still need to clean even if they use no-clean flux soldering components.
電子工作是超聲波清洗機(jī)清洗運(yùn)用最早,最為廣泛的工作。電子零件的清洗:電子零件,如半導(dǎo)體管的殼座、IC的殼座、晶體的殼座、繼電器的殼座、電子管座等。超聲波清洗機(jī)電子元器材的基體清洗:電子元器材的基體是由半導(dǎo)體材料制成并封裝在金屬或塑料殼座中構(gòu)成的,在封裝前,不但對殼座有必要清洗,而且也有必要對基體進(jìn)行清洗,如IC芯片、電阻、晶體、半導(dǎo)體、原膜電路等。
In particular, high-density PCBs and high-density ICs are not cleaned or cleaned by ultrasonic cleaners, which will cause dust to be absorbed between high-density lines and ICs. Once the humidity is high, high-density lines can easily occur. Short-circuit between the feet and the shortcomings, and once the environment is monotonous, the short-circuit shortcomings are not seen by themselves, and such shortcomings are not easy to find. Therefore, electronic machine factories all over the world insist on ultrasonic cleaning of PCB boards. In China, the military electronics complete machine factory has begun to promote, and received the two-tiered benefits of both improving product reliability and reducing after-sales service costs.
超聲波清洗機(jī)對PCB板的清洗:我國電子工作中,絕大多數(shù)公司都在運(yùn)用PCB,PCB組件焊接選用的助焊劑分為水溶型、松香型和免清洗型三類,運(yùn)用較多的為前兩種,多選用超聲波清洗機(jī),免清洗型原則上應(yīng)當(dāng)不清洗,但是,世界各國的大多數(shù)廠家即便選用免清洗型焊劑焊接組件,仍需要清洗。
In the production of connectors, connectors, adapters, etc., it is also necessary to clean the ultrasonic cleaner before plating and assembly. Otherwis超聲波清洗機(jī)e, the dust and oil adsorbed on these assembled parts will affect its electrical and insulating functions, especially some messy. This is especially true for multi-core connectors.
特別是高密度PCB以及高密度IC出腳不清洗或不選用超聲波清洗機(jī)清洗,必將致使高密度線路之間和IC出腳之間吸附塵土,一旦環(huán)境濕度大,很容易發(fā)生高密度線間和腳間短路而呈現(xiàn)缺點(diǎn),而一旦環(huán)境單調(diào),短路缺點(diǎn)又自行不見,這類缺點(diǎn)又不易查找。所以世界各國的電子整機(jī)廠均堅持對PCB板作超聲波清洗。在我國,軍工電子整機(jī)廠已開端推廣,并收到了因此舉既提高了產(chǎn)品可靠性,又降低了售后服務(wù)本錢的兩層效益。
Cleaning after processing of electronic materials: electronic materials such as wafers, silicon wafers, piezoelectric ceramic sheets, etc. are products supplied by the manufacturer of the elementary equipment. It is necessary to clean the products before leaving the factory, especially for manufacturers who make oral affairs. Big problem, ultrasonic cleaner cleaning is the most useful way. 接插件、連接件、轉(zhuǎn)接器等器材的生產(chǎn)中,電鍍和組裝前也有必要超聲波清洗機(jī)清洗,不然吸附在這些組裝零件上的塵土、油污必將影響其導(dǎo)電和絕緣功用,特別是一些凌亂的多芯連接器特別如此。
電子材料加工成型后的清洗:如晶片、硅片、壓電陶瓷片等電子材料是供應(yīng)元器材廠家的產(chǎn)品,其產(chǎn)品出廠前有必要清洗,特別是作出口事務(wù)的廠家,其產(chǎn)品清洗成為一大難題,超聲波清洗機(jī)清洗是最有用的途徑。
