随着电子产品的不断小型化,贴片式集成电路的应用越来越广泛。而它的维修与焊接也是广大业余爱好者所关心的问题,笔者根据多次更换总结的经验,特归纳如下: 1.用针式电烙铁将松香均匀涂在片状集成电路(以下称IC)引脚四周,防止焊下IC肘损坏焊盘;启动热风枪,待温度恒定后,快速围绕IC转动,使各 With the continuous miniaturization of electronic products, the application of chip integrated circuits is more and more widely used. And its maintenance and welding is also the concern of the majority of hobbyists, the author based on the experience of multiple replacement summary, especially summarized as follows: 1 with a needle soldering iron evenly coated in the chip IC (hereinafter referred to as IC) Around the pin, to prevent welding pad IC elbow damage pad; start hot air gun, until the temperature is constant, quickly around the IC rotation, so that each
