A container neck and closure assembly, wherein the container neck comprises a first screw thread on an internal surface thereof and the closure comprises a cylindrical plug for insertion into the container neck, said plug having a second screw thread on an outer surface thereof for engagement with the first screw thread to secure and resecure the closure on the neck. The charge pump starts in an off state and a determination is made if the input voltage is less than or equal to the output voltage. The carrier substrate 73a is then pressed toward a support substrate or a desired circuit layer, thereby contacting connecting portions 12 of the chips 13 on the carrier substrate 73a with corresponding predetermined positions on the support substrate or a circuit layer.
