Quite a bit of heat is needed, due to the thickness of the copper pipe, and an electrical soldering iron probably won't be able to deliver sufficent heat. 因為銅管有一定的百度，所以有可能錫焊的溫度不夠，它對溫度的要求是比較高的。
Laser soldering technology has been found an important application in micro-electronic joining and packaging. 激光軟釬焊技術(shù)在微電子焊接和封裝方面具有重要的應用價(jià)值。
