Abstract

本发明公开了一种用于铜包钢线外镀锡的助焊剂，包括酒精和食用乳酸，所述酒精与食用乳酸的重量比为4：1。本发明通过酒精与食用乳酸来提高镀层与引线之间的结合率，防止镀层在长时间放置后脱落。

Description

一种用于铜包钢线外镀锡的助焊剂
技术领域
本发明涉及一种用于铜包钢线外镀锡的助焊剂。
背景技术
近年来，随着电子工业的迅速发展，为了改善电子元件和材料的可焊性和降低成本，采用在电子元件的引线上镀上可焊性良好的镀锡层。使用目前的镀锡溶液在引线表面可获得光亮的镀层，但镀层与引线的结合率较差，引线在空气中存放2～6个月后，镀层便便会慢慢脱落。
发明内容
针对上述问题，本发明提供了一种用于铜包钢线外镀锡的助焊剂，具有良好的结合率，在空气中长时间放置后镀层也不会脱落。
本发明采用的技术方案是：
一种用于铜包钢线外镀锡的助焊剂，包括酒精和食用乳酸。
作为优选，所述酒精与食用乳酸的重量比为4：1。
本发明通过酒精与食用乳酸来提高镀层与引线之间的结合率，防止镀层在长时间放置后脱落。
具体实施方式
下面通过具体的实施例对本发明做进一步的详细描述。
一种用于铜包钢线外镀锡的助焊剂，包括酒精和食用乳酸，所述酒精与食用乳酸的重量比为4：1。
本发明的使用方法为：在进行镀锡前，将铜包钢线浸入助焊剂中，再送入锡炉进行镀锡，这样得到的镀层，结合率和，长时间放置后不会脱落。
