第七步检查焊接质量,脚和脚之间不要连焊,不要有小焊珠以及不要漏焊.

就是用烙铁先在焊盘扫一层薄锡，然后放上ic挨个加热ic脚就ok了，又快又干净

我也是这样做的。[em11][em11]

高手
一针见血,焊锡是多了点以后焊接时会多加注意.
这个焊得是否可以?请指导.

谢谢

先将焊盘上锡，接着固定芯片，再在各个脚旁用烙铁熔解松香，最后用较尖的烙铁在各个脚尖一划而过，焊完后用天那水清洗，会焊得很漂亮的。

为什么不用锡膏呢? 在印板上涂一层薄薄的锡膏,在拿烙铁或热风枪烫一下或吹以下就可以了.

我在单位用的也是它！
不过家里用的是比它还好的ERSA！[em11]





楼上的老兄图里给的那种SMT的还不算难焊，真正难搞的是下面我给出的主板里的那种BGA的南桥和北桥芯片！楼主说的这种SOIC的28脚的对我们 ...

这么大的BGA，说老实话，没有焊过，但是手机的CPU就焊得多了，一般是190多脚吧。BGA太大了，不容易焊，温度要掌握好。
体积大，温度升得慢，风枪的温度不能调太高，焊接时间长容易烧。
