Abstract: A test fixture for an electronic device is provided that removes debris from a socket of the test fixture using back side air blow off. In general, the test fixture includes a circuit board, a socket on a front side of the circuit board, and an air manifold on a back side of the circuit board. Pressurized air is provided to the air manifold through an air supply inlet coupling the air manifold to an external pressurized air supply. At least one via formed through the circuit board fluidly couples the air manifold on the back side of the circuit board to the socket on the front side of the circuit board. Accordingly, the pressurized air from the air manifold flows through the vias and up through the socket such that debris is removed from the socket.

Abstract: An electrode for a rechargeable lithium-ion battery is formed by mixing stanous oxide (SnO) and lithium nitride (Li3N) in a stoichiometric ratio of 2 moles of Li3N to 3 moles of SnO to form a mixture, milling the mixture to obtain a milled powder, and processing the milled powder in accordance with an electrode-forming technique. The electrode forming technique can be any one of die pressing, spraying, doctor-blading and rolling. Conductive additives, such as carbon and binders (PVDF, cellulose and Teflon), can be introduced during the processing step. Preferably, the method is carried out in a dry, inert atmosphere of argon or helium. As a result of the invention, a smaller, lighter and more efficient lithium-ion battery is produced.
