在电子制作中,如何进行焊接是一个很重要的问题。本文介绍焊接的有关知识。1. 电烙铁的选择电烙铁是焊接最主要的工具。除常用的内热式与外热式电烙铁外,还有吸锡式和恒温式的电烙铁。目前市售的多为内热式电烙铁,常用规格有20W、40W、70W几种。选择哪一规格的电烙铁,可根据具体的焊接对象来决定。如果是装制半导体收音机和其它低电压的小型电子制作,那么20W电烙铁是最佳
In electronic production, how to carry out welding is a very important issue. This article describes the welding knowledge. 1. The choice of electric iron Electric soldering iron is the most important tool. In addition to the commonly used thermal and external thermal iron, there are suction-type and thermostat-type electric iron. Currently available in the market mostly electric soldering iron, commonly used specifications are 20W, 40W, 70W several. Choose which size of electric iron, according to the specific welding object to decide. 20W electric soldering iron is the best if it is made of semiconductor radios and other low voltage miniature electronics
