3 disposing of a battery in fire can cause the battery to rupture . also avoid placing batteries in water , as this causes batteries to cease to function 不可直接在电池上焊锡，需用连接片进行焊接不可拉扯电池的引线插头，以免损害插头焊点及连接部位。
The major issues of this task are unstable images due to specular reflection of solder surfaces and large variations of solder shapes 焊点瑕疵一直是电子工业界亟待解决的问题，而其遭遇之困难又可分为焊点表面的高度镜面反射特性与焊点形状的高度变异性等两类。
Carefully handle the solder and ensure all the contact points and solder are clean - try different quantities of solder , make sure your soldering iron has been adjusted to the best temperature -不同的焊点:线路焊点的运用位置搭配,焊种不同,焊量的比例,温度的调整
Through appearance testing , x 射线 testing and temperature cycling testing , the reliability of mixed solder joints and 无 铅 solder joints which formed under various process parameters was assesed 通过对不同工艺参数下形成的混合焊点和无铅焊点进行了外观检测、 x射线检测和温度循环测试。
