Abstract: An electrical device that comprises a printed circuit board, which has a first mounting surface, a second mounting surface, a mounting edge, and a plurality of mounting pads on the first mounting surface and the second mounting surface, and an electrical component that has a ball grid array. The electrical device further comprises an adaptor, interposed between the mounting edge and the electrical component, and comprising a body, made of an electrically non-conductive material, and a plurality of electrical pins, made of an electrically conductive material and passing at least partially through the body of the adaptor. The first end of each one of the plurality of electrical pins is electrically directly mounted to a corresponding one of the spaced apart solder balls. The second end of each one of the plurality of electrical pins is electrically directly mounted to a corresponding one of the plurality of mounting pads.

Abstract: An electrical device that includes a ball grid array (BGA) component, comprising signal processing circuitry, a component mounting surface, and a BGA, which has solder balls that are spaced apart from each other on the component mounting surface. The electrical device also includes a plurality of electrical wires, each electrically coupled directly to a corresponding one of the solder balls of the BGA component. The electrical device further includes a wire fixation element, through which the plurality of electrical wires at least partially pass through. The wire fixation element is coupled to the plurality of electrical wires and configured to fix the electrical wires relative to each other so that the electrical wires do not move relative to each other.

Abstract: Disclosed herein is a use-limiting connector for limiting use of an electrical tool. The use-limiting connector includes an electrical circuit, a plunger, movable between a first position and a second position, and a biasing member, configured to urge the plunger into the first position and configured to incrementally uncoil into respective torsional states as the plunger moves between the first position and the second position. With the plunger in the first position and the biasing member in a first one of the torsional states, the biasing member closes the electrical circuit. As the plunger moves from the first position to the second position, the plunger moves the biasing member to open the electrical circuit.
