当实验制作即将成功之际,却碰到停电或者元件损坏的时候,你将束手无策。但本文可解你燃眉之急。一、无电烙铁找一20W烙铁芯(坏的)及直径约4mm,长为1.5cm的紫铜条。然后将烙铁芯打松,取其外瓷管。把铜条稍为锉细之后放入瓷管内,接上手柄即在为一支无须电源的火烙铁了。该方法简单、取材容易,适用于缺电的农村及停电时使用。它尚有一个优点——焊接集成电路时不怕静电击穿。烙铁外形见图1。 When the experimental production of the upcoming success, but encountered power outages or component damage, you will do nothing. But this article can solve your urgent needs. First, no electric iron to find a 20W iron core (bad) and a diameter of about 4mm, length of 1.5cm copper bar. Then iron core loose, whichever is the outer tube. Put the copper rod into the porcelain tube after it is slightly filmed, and connect the handle to the fire iron without power supply. The method is simple, easy to draw, suitable for power shortage in rural areas and power outages. It also has the advantage of not being afraid of electrostatic breakdown when soldering integrated circuits. Figure 1 iron shape.
