4.12 Soldering SMD Operational Amplifier
SMD-ICs like the operational amplifier LM358 are soldered similarly to small SMD diodes.
It is a little easier because they are slightly larger. First, pre-tin an IC field pad with a little
solder. After determining the IC installation position by the mark, align it on the PCB with
