- Use a paste mask to apply solder paste to the SMD pads.
- Place the SMD parts on the solder.
- Use an oven or hotplate to reflow the solder.
- Alternatively the SMD parts and pads are big enough to hand solder.
- Hand solder the through hole connectors, switches, LED and L6203. The LED's flange should align with the board edge.
- Solder wires into the tink_buck converter, mount it on a double sided sticky pad and solder the wires to the PCB.
- Crop all the leads short on the underside of the board.
