焊接元件时宜选用低熔点的松香焊锡丝。焊接时要用镊子夹持元件的引脚，一是可固定元件不动，一是可以散热以保护元件。焊接时烙铁头的温度要适当，被焊元件和烙铁的接触时间也要适当，焊接时间过短会造成虚焊，但焊接时间过长又会烫坏元件。一般元件的焊接时间以2-3s为宜。焊点处焊锡未凝固前，不能摇动元件或引线，否则会造成虚焊。焊接元件过程中烙铁头不要移动，否则会影响焊点的质量。对特殊器件的焊接应按元件要求进行，如CMOS器件要求电烙铁金属外壳不带电并应接地。有条件时最好使用防静电电焊台，没有条件时，可先加热电烙铁，待焊接时把电烙铁从电源插座上拔下，利用余热进行焊接。焊接完成后，要用无水酒精把电路板上残余的助焊剂清洗干净。焊接技术是仪表工必须掌握的一项基本功，也是保证仪表可靠工作的重要环节，仪表工要争取多焊接，多操作，才能在实践中不断提高焊接技术。
