一、概述在无线电、电子、电工行业中,普遍使用着为数众多的搪锡缸。电子元器件的引脚经过搪锡处理,提高了可焊性,大大地减少了虚焊和假焊。但是,在交电商店出售的搪锡缸,都显得体大量重,携带不便,而且在结构上几乎都采用外热式——用电热丝构成的加热器都安装在锡缸外围,使得加热器发出的热,只有一部分作用在锡缸上,使锡缸内温度升高,把焊锡熔化;而另外
First, an overview In the radio, electronics, electrical industry, the widespread use of a large number of billet tank. The pins of electronic components have been tin-coated to improve the solderability, greatly reducing the Weld and fake welds. However, the Bintang sold at the Dianpao shop has become quite heavy and inconvenient to carry, and almost all of the structures are externally heated - the heaters made of electric heating wire are mounted on the periphery of the tin cylinder so that the heater Issued heat, only part of the role in the tin cylinder, so that the temperature inside the tin cylinder, the melting of the solder; while the other
