What is the insertion principle of plug-in electronic components?

1. Manual insertion and welding should be first inserted into those components that need to be mechanically fixed, such as the power device radiator, bracket, clip, etc, and then insert the need to weld fixed components. Do not touch the device pins and the copper foil on the printed board directly.

2 Automatic mechanical equipment plug-in, welding, Those parts with low height should be inserted first, then those with high parts should be installed. The valuable key parts should be placed at the last plug:radiator, bracket, clip, etc. The plug should be close to the welding process.

3 Metallized hole welding, more than two layers of printed circuit board holes are to be metalized. When welding, not only the solder wetting pad, but also wetting and filling the hole. Therefore, the heating time of the metallized hole should be longer than that of the single plate.
