Be certain each pin is located over the correct pad on the PCB.
2. Apply flux to all of the pins on the IC.
3. Being careful to not unsolder the tack points, slide the soldering
iron along the tips of the pins while feeding enough solder to the
tip so that it flows under the pins as they are heated.
7.3. REMOVING SOLDER FROM BETWEEN PINS
1. Add a small amount of solder to the bridged pins.
2. With a hot iron, use a sweeping motion along the flat part of the
pin to draw the solder from between the adjacent pads.
