How to solder and use the SMD battery holder on PCB ?

In my work,I've noticed that some colleagues don't quite understand how to solder SMD battery holders. So, I'll explain it to everyone this time:

1.  Pad positions for the chip component are pre-reserved on the PCB board.

2.  Align and place the positive and negative metal contact pads accordingly.

3.  Before placing the chip battery holder, solder paste is applied to the soldering surface in advance.

4.  Firmly solder the metal contact pins of the battery holder to the soldering surface.

5.  Proceed with power-on application.
