1.电阻、三极管、二极管的更换:对上述元件只要用尖镊子夹住元件,然后给各引脚加热,元件即可取下。如在加热时发现有的两焊点连上了暂时也不用管它,等把元件拆卸下来清理开所连焊点即可。拆卸用的烙铁用普通烙铁(头)或专用尖烙铁(头)均可,焊接时最好用专用尖烙铁(头)。镊子要用口好的,不然的话稍稍使不好劲,元件就会给崩丢。焊接时,先焊一端定位,然后再焊其他引脚。
1. Resistor, transistor, diode replacement: As long as the above components with sharp tweezers clamp the components, and then to the pin heating, the components can be removed. As found in the heating of some of the two solder joints connected to the temporary do not have it, so the components removed to clean up even with the solder joints can be. Disassembly of the soldering iron with ordinary iron (head) or special tip iron (head) can be used when welding the best tip iron (head). Tweezers to use the mouth good, otherwise slightly less than good, the components will give collapse lost. When welding, first solder one end positioning, and then welding other pins.
