The soldering of surface mount resistors is actually the same for all surface mount capacitors and resistors. The basic steps for soldering most of these components are: selecting the PCB board, first fixing one pin of the solder patch component, and then soldering the other side. The following figure lists these steps; For more detailed information, please follow the following:

1、 Tool for SMT welding

1. Thermostatic soldering iron

2. Welding aid pen

3. Tin wire

4. Plate washing water

5. Camera

2、 International standard steps for surface mount welding

1. Place the PCB board in a suitable position on the workbench

2. Use a camera to first take the corresponding position of the patch component and place it on the PCB board

3. Use a soldering aid pen to apply a certain amount of flux on the solder pads of the surface mount

4. Use a soldering iron (around 360 degrees) to add tin to the other solder pad

6. Use a soldering iron to tin one side of the surface mount component and fix it in place

7. Use soldering iron to fix the other side of the surface mount component with tin
