Abstract: An apparatus for modifying an electrical circuit includes a first electrical contact, a second electrical contact, an electrical coupler formed of an electrically conductive material, a first assembly including a cavity, a driving portion, an inhibiting portion, and a second assembly electrically coupled to the second electrical contact. The electrical coupler is moveable within the cavity along a movement axis, a wall of the cavity is electrically coupled to the first electrical contact and to the electrical coupler, and when the electrical coupler is disposed at an initial position within the cavity, the electrical coupler is not electrically coupled to the second electrical contact. The driving portion applies a first force on the electrical coupler in a movement direction along the movement axis. The inhibiting portion inhibits the movement of the electrical coupler along the movement axis.

Abstract: A method of joining a surface-mount component to a substrate includes placing a piece of solder on top of the substrate and temporarily bonding the piece of solder to the substrate with at least one temporary bond. The method also includes placing a surface-mount component on top of the substrate with a bottom face of the surface-mount component facing the substrate. The surface-mount component has at least one lateral side. The method further includes positioning the surface-mount component with the at least one lateral side proximate the piece of solder, heating the substrate and the piece of solder to a joining temperature for a time sufficient for the solder to flow into an area between the bottom face of the surface-mount component and the substrate, and cooling the substrate and solder.

Abstract: A method for making a liquid barrier includes forming a liquid barrier layer on a substrate, forming a mask layer on the liquid barrier layer such that part of the liquid barrier remains exposed, forming a contact layer on the exposed liquid barrier layer, and removing the mask layer to expose the part of the liquid barrier layer which was covered by the mask layer. A liquid wetting boundary is formed when the wettability on the liquid barrier surface area is less than the wettability of the contact surface area.
