After the columns and rows are soldered, it's time to connect them to the key switches. Solder a diode on each key switch pin. This will protect the key switch pins from current and prevent them from being shorted. The diode will only allow current to flow in one direction, and it also has a an indicator in black that indicates which way the current will flow.
