It has five rows and 17 column.

Once the rows and columns are soldered, it's the time to connect them to key switches. Solder a diode to each key switch pin. This will shield the pins from current, and prevent them from being shortened. A diode permits current to only flow in one direction. It comes with a visual indicator that is black, that indicates which direction current will flow.
