For most PCBs, the controller and resistors are already soldered on. Just plug the PCB into your computer's USB port and got to keyboardtester.com or similar and bridge each set of pins. When you press a switch, the leafs make contact and bridge the connection. So bridging the pin sockets with a metal tweezers is doing the same thing.
