Soldering Tutorial for SMD Components - Drag Soldering Techniques (I)

The most effective way to solder SMDs is drag soldering. If you are familiar with drag soldering, you can basically use a soldering iron + rosin to complete the soldering of all SMDs.

Before welding, we specifically mentioned the tools:
it is best to use a flat-head soldering iron with an oblique mouth. Considering the anti-static requirements for actual welding in the future, it is recommended to use a soldering station!

Let’s get back to the point:

First, place the IC flat on the pad

After alignment, press with your hand

Then use the melted solder wire to randomly solder several pins of the IC to fix the IC

Fix all four sides with melted welding wire

After fixing, evenly solder the wire on the head of the IC pin.

Weld wire all around
