这是什么原因造成的呢？同创力焊锡网技术人员今天就这些问题给大家谈一下。
电路板短路：当电路板焊接后接过老化的程中会发现一些电路板短路，排出电路板设计及电子原器件的问题之外，可以从以下几个方面来查找电路板焊锡时吃锡时间太短，造成焊接不良。
助焊剂本身活性不强，减弱了焊锡的润湿性及它的扩展性。
线路板进锡的方向与锡波的方向逆向，焊锡的液面氧化物过多影响焊接。
焊锡后锡点灰暗无光泽：焊锡后发现锡点灰暗无泽，从两个方面来讲一是焊锡的度数过低。
焊锡达到含锡50%以上焊点都会有光泽。
另外一方面就是助焊剂的残留物停留在锡点的表面上没有清洗而它的酸类物质腐蚀了焊点也会造成锡点的灰暗无光泽焊锡后锡点表面呈粗糙：锡点表面的粗糙首先要从焊锡的质量来讲，焊锡里面本身含有各种少量的金属元素，当这些金属元素的含量超过它的极限时会影响锡点的表面。
焊锡时要求锡液的表面无杂质，当锡液的表面氧化过多时要及时清理否则会影响锡点的表须。
焊锡丝技术说明
低温焊锡其实就是含铅焊锡，高温焊锡则是无铅焊锡。
低温焊锡是63/37的比例，63%是锡，37%是铅。
之所以用铅，就是要降低锡的熔点。
因为早期的电子元器件 纯锡的熔点很高，但如果加了1%左右的银，熔点就会降下来，当然还是比63/37的锡高几十度。
63/37的锡还一个好处就是便宜，如果63/37的锡35元，纯锡就60元，加银后就65元（只是个大概）。
加了银 所以高温低温，本身只是一个环保的因素。
但由于无铅焊锡的低电阻率，所以用在音响上效果会更好（感觉。
因为早期的电子元器件对高温很敏感。
以上比例的焊锡不知道用了多少年了，直到人们对铅中毒的了解越来越多。
现在很多锡高几十度。
（只是个大概）。
加了银的焊锡一个好处就是电阻率低，很简单因为银的导电是最好的。
音响上效果会更好（感觉的效果）
了解越来越多。
现在很多欧洲国家已经禁止使用含铅焊锡了。
