SMD 电阻器和电容器(如果您在谈论陶瓷)比 SMD 半导体更耐温;我从来没有能够损坏任何东西,有时我很辱骂;另一方面,半决赛是一项更容易炒的任务……
Anyway, don't try to solder them with solder wire; instead, buy some SMD solder paste, apply a small amount on the solder points with the tip of a wooden splurge (that's what works best for me), place the resistor/capacitor over it with a tweezer and use a hot air rework tool to heat it and melt the solder. Or, if you don't have a HART, use the soldering iron tip to heat the board copper of one of the contacts until the solder melts, wait a few seconds and do the same to the other contact. This will take 2-3 seconds, which is tipically safe even for diodes. In both cases, use the lowest temperature that can still melt quickly the solder. For leaded solder, I use 390F, for lead-free 420F. Even with a soldering iron, it is essential to have a temperature-controlled one.
最后,我用的最小的SMD零件是0805;至少在我的情况下,较小的人很难完成快速干净的工作(显然,如果您的处理技巧比我的好,这对您来说可能会有所不同)。
