Abstract: A circuit board includes a substrate and a metallic layer. A first area and at least one second area are defined on a portion of the substrate, the second area is located outside the first area. The metallic layer includes first test lines disposed on the first area and second test lines disposed on the second area. A first test pad of each of the first test lines has a first width, and a second test pad of each of the second test lines has a second width. The second width is greater than the first width such that probes of an electrical testing tool can contact the first and second test pads on the circuit board correctly during electrical testing.

Abstract: Semiconductor devices and methods are disclosed herein. In one example, a disclosed semiconductor device includes: an insulation layer, a first electrode with sidewalls and a bottom surface in contact with the insulation layer; a second electrode with sidewalls and a bottom surface in contact with the insulation layer; and an insulator formed between the first electrode and the second electrode. The insulator is coupled to a sidewall of the first electrode and coupled to a sidewall of the second electrode.

Abstract: A manual vacuum device is introduced to provide vacuum isolation in a container. The manual vacuum device comprises a lower cover disposed on the container and an upper cover rotatably disposed on the lower cover to form a first air chamber. The lower cover includes a first air channel fluidly communicating the container with the first air chamber and a first check valve disposed within the first air channel to prevent air from flowing back to the container. The upper cover includes a second air channel fluidly communicating the first air chamber with the external environment and a second check valve disposed within the second air channel to prevent air in the external environment from flowing back to the first air chamber. The air in the container exhausts to the external environment by the rotational movement of the upper cover relative to the lower cover.

Abstract: An electrical and manual dual purpose jack lift includes a base, a pair of lower bracing arms having a first end hinged on the left side and right side of the base, a connection member located above the base, a pair of upper bracing arms having a first end hinged on the left side and right side of the connection member, and a screw bar having a tail end fastened to an axle. The upper and lower bracing arms have second ends hinged on the axle and an anchor axle. The screw bar has a head end running through the anchor axle. The head end of the screw bar is movably coupled. The screw bar has a distal end coupled with an elastic element which pushes the axle to fasten to the screw bar and prevents the upper and lower bracing arms from hitting each other to avoid damage.

Abstract: A magnetic retarding device for an exerciser including a pair of links each having a lower end to the frame of the exercise, a bracket pivotally coupled pivotally coupled between the upper ends of the links which are arranged such that the bracket moves radially inward and outward of the wheel of the exerciser, a support fixed to the bracket and including one or more magnets disposed in two end walls, the magnets are caused to move radially inward and outward of the wheel when the bracket moves.
