Next comes the key point of drag soldering! Place the PCB at a 45-degree angle, and imagine that the solder wire on the IC pin can flow down smoothly when it melts!
Reference address：Soldering Tutorial for SMD Components - Drag Soldering Techniques (Part 2)
Put the soldering iron tip into the rosin and shake off the excess solder on the soldering iron tip.
Quickly place the soldering iron tip with rosin on the soldering part of the tilted PCB head.
The next action will be the core of the whole drag soldering: make the soldering iron move in the following way
Repeat the above steps to achieve the following results
Use the same method on all four sides
Fixed patch
Apply solder
Fixed IC pin
