    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: 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: Disclosed herein is an electrical connector, comprising a plug and a receptacle. The plug comprises first electrical contacts electrically isolated from each other and arranged into a first outer contact annulus and a first inner contact annulus concentric with and radially spaced apart from each other. The receptacle comprises second electrical contacts electrically isolated from each other and arranged into a second outer contact annulus and a second inner contact annulus concentric with and radially spaced apart from each other. The plug is selectively connectable with the receptacle. When the plug is selectively connected with the receptacle, each of the first electrical contacts of the first outer contact annulus is in physical contact with a corresponding one of the second electrical contacts of the second outer contact annulus and each of the first electrical contacts of the first inner contact annulus is in physical contact with a corresponding one of the second electrical contacts of the second inner contact annulus.
