Soldering the amplifier chips

The process is the same as with the capacitors, just a bit more delicate. In addition, the chips have to be oriented in a particular way to function correctly (whereas the capacitors we’re using could be either way around).

As with the capacitor, apply solder to one of the pads that the chip will rest on. You don’t need very much.

Use tweezers to position the chip, with the gray stripe towards the top. Use the iron to melt the solder and hold the chip in place.

The solder should hold the chip in place. Make sure that the other legs are aligned with the pads on the circuit board.

Solder the other legs of the chip. Again, don’t use too much solder or you might connect two legs together.
