DIP后焊制程大致可分为手工焊接，自动送锡焊台焊接，自动焊锡机焊接三种类型。后焊制程中经常会遇到过锡珠飞溅这种现象，那么我们在操作过程中如何避免DIP后焊制程中的锡珠飞溅现象呢？

手工焊接前采用自动破锡机提前对焊锡丝进行破锡处理后再使用，其原理就是在破锡机自动送出锡线时利用经过特殊设计的圆形破锡刀片在锡线上打出一个个小孔，这样在焊接时就会使里面的助焊剂在烙铁加热时气化，在锡线融化之前渗出一部分，从而达到降低锡珠飞溅的目的。

使用自动焊锡机降低锡珠飞溅，在送锡过程中给锡丝进行100°C左右的预热处理、再送到烙铁头最前端焊接产品、可以减少焊锡丝焊接时温度的急剧变化，从而达到降低锡珠飞溅的目的，此外由于锡丝预热装置体积相对偏大，在设备的现场使用过程中具有一定的局限性，因此在自动焊锡机上使用此种送锡方式的较少。

破锡型精密送锡系统，在自动送锡的同时、利用经过特殊设计的圆形破锡刀片在锡线上打出一个个小孔，这样就会使里面的助焊剂在烙铁加热时气化，在锡线融化之前渗出一部分，从而达到降低锡珠飞溅的目的，此种方法是目前市场上应用最为广泛的主流技术。
