description A control unit having a connection structure for connecting components of the control unit to a base plate which eliminates the need for separate fasteners. The control unit includes circuitry mounted to a PCB, and the PCB is pre-assembled to a base plate, to form a pre-assembly. During assembly, the PCB and the base plate are aligned when placed in a tooling device which clamps and holds the pre-assembly in place during the over molding process. The circuitry is over molded with an epoxy material, such that the epoxy material flows from a top side of the PCB to underneath the base plate, and the PCB is fixed to the base plate without the use of fasteners such as screws, or adhesive materials.
