Abstract
According to an exemplary embodiment, a bondwireless power module residing on a top surface of a substrate includes at least one input power pad providing power to the module and at least one output current pad providing output current from the module. At least one press-fit input power clamp engages a top side of the at least one input power pad, and engages a bottom surface of the substrate. Also, at least one press-fit output current clamp engages a top side of the at least one output current pad, and engages the bottom surface of the substrate. The at least one press-fit input power clamp can include at least one top prong and at least one bottom prong. Furthermore, the at least one bottom prong can press the input power pad into the at least one top prong.

A bondwireless power module residing on a top surface of a substrate, said module comprising:
- at least one input power pad providing power to said module;
- at least one output current pad providing output current from said module;
- at least one press-fit input power clamp comprising input prongs engaging a top side of said at least one input power pad, and engaging a bottom surface of said substrate, such that said substrate is situated between said input prongs;
- at least one press-fit output current clamp engaging a top side of said at least one output current pad residing on said top surface of said substrate, and engaging said bottom surface of said substrate;
- at least one conductive clip being coupled to said top side of said at least one input power pad to form part of a power bus.
A bondwireless power module residing on a top surface of a substrate, said module comprising:
- at least one input power pad providing power to said module;
- at least one output current pad providing output current from said module;
- at least one press-fit input power clamp engaging a top side of said at least one input power pad, and engaging a bottom surface of said substrate, said at least one press-fit input power clamp providing electrical connection to a first external circuit;
- at least one press-fit output current clamp comprising output prongs engaging a top side of said at least one output current pad, and engaging said bottom surface of said substrate, such that said substrate is situated between said output prongs, said at least one press-fit output current clamp providing electrical connection to a second external circuit.
