It's not a standard way to do it, but you should plan how to connect 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 to connect.

After the rows and column are joined It is now time to connect the key switches. To do this, you need to place a diode on each key switch pin and then solder it. This will shield the pins of the key switch from current and keep them from being shorted. The diode allows current to only flow in only one direction.
