First, let us understand the benefits of SMD components. Compared with leaded components, chip components have many advantages.

Small size, light weight, easy to store and mail. For example, the commonly used chip resistor 0805 package or 0603 package is much smaller than the in-line resistor we used before. Dozens of in-line resistors can fill a bag, but if it is replaced with chip resistors, it is enough to hold thousands or even tens of thousands. Of course, this is without considering the maximum current it can withstand.

Second, SMD components are easier to solder and disassemble than in-line components. SMD components do not need vias and use less tin. The most troublesome and most troublesome part of in-line components is disassembly. Friends who have done it have this experience. Even if there are only two pins on a two-layer or more-layer PCB board, it is not easy and easy to remove it. If the circuit board is damaged, not to mention the multi-pin ones. It is much easier to disassemble the SMD components, not only is it easy to disassemble the two pins, even if the components with one or two hundred pins are disassembled several times, the circuit board will not be damaged.

Three, SMD components also have a very important advantage, that is, it improves the stability and reliability of the circuit, and for the production, it improves the success rate of the production.

This is because the chip components are small in size and do not require vias, thereby reducing stray electric fields and stray magnetic fields, which are particularly important in high-frequency analog circuits and high-speed digital circuits. The review said that the author can take the responsibility;, as long as you adapt and accept the SMD components, unless you have to, you may never want to use in-line components anymore.
