What is the difference between electronic component plug-ins and patches?

For some small signal devices, such as resistors, ceramic capacitors, control chips, etc.

The use of patches is superior to plug-ins because the production process is relatively easy to control, the process defect rate is low, and some materials are better than plug-ins. However, it is less resistant to shocks than plug-ins. But the overall patch will be better than the plugin.

Then for power-type devices such as MOSFETs, electrolytic capacitors, power resistor plug-ins will be good with the patch. Because the power device heat is more serious, the heat dissipation of the plug-in is better than the patch.

In general, SMD process welding is reliable and stable, and the failure rate is low. Suitable for large-area welding of stable electronic product models, it is the mainstream welding process in the current electronic product market. If the engineer changed some of the original SMD components into plug-ins, he naturally had his considerations. For example, the circuit analysis during the product trial phase, as well as the factors that make it easy to solder, may be the reason for choosing a plug-in.
