It's not a standard way to go about it, but you should determine how to route and solder each column and row. For this keyboard, there are five rows and 17 columns, so there will be 22 microcontroller wires and pins that you need to connect.

Once the rows and columns are soldered, it's time to connect them to the key switches. To do this, put a diode on each key switch pin and then solder it. This will protect the pins from current, and prevent them from being shortened. A diode allows current to only flow in only one direction. It has a visual indicator that is black, that indicates which direction current will flow.
