  • Publication number: 20210311095
    Abstract: A probe card and a probe module thereof are provided. The probe card includes a first strengthening board, a fixed frame, a probe module, and a slidable frame. The first strengthening board includes a top surface, a bottom surface, and a mounting hole. An inner wall of the mounting hole is formed with an inner flange. The fixed frame is disposed on the top surface of the first strengthening board and surrounds the mounting hole. The probe module is disposed in the mounting hole and includes an outer flange including a physical region and multiple gap regions. The physical region abuts against the inner flange of the first strengthening board. The slidable frame is disposed on an inner wall of the fixed frame and is slidable between a released position and a fixed position. Multiple pressing portions are disposed on an inner wall of the slidable frame.

  • Publication number: 20210102992
    Abstract: An adjustable probe device includes fixed and movable probes, at least one of which is a signal probe having a coaxial structure. The movable probe is linearly slidable with a ground unit thereof abutted against a ground unit of the fixed probe. Another adjustable probe device includes a first movable probe for being grounded, and fixed and second movable probes both having a coaxial structure. Any of the two movable probes is selectable to be a functioning probe in a way that the contact ends of the functioning and fixed probes are located on a same plane for contacting two pads of a DUT at the same time, and the functioning probe is linearly slidable with a ground unit thereof abutted against a ground unit of the fixed probe. As a result, the probe interval is adjustable, lowering the cost of the impedance testing apparatus for circuit boards.

  • Publication number: 20200116758
    Abstract: A probe module includes a circuit board and at least one probe formed on a probe installation surface of the circuit board by a microelectromechanical manufacturing process and including a probe body and a probe tip. The probe body includes first and second end portions and a longitudinal portion having first and second surfaces facing toward opposite first and second directions. The probe tip extends from the probe body toward the first direction and is processed with a gradually narrowing shape by laser cutting. The first and/or second end portion has a supporting seat protruding from the second surface toward the second direction and connected to the probe installation surface, such that the longitudinal portion and the probe tip are suspended above the probe installation surface. The probe has a tiny pinpoint for detecting tiny electronic components, and its manufacturing method is time-saving and high in yield rate.

  • Patent number: 5456615
    Abstract: This invention relates to a C type lamp string improvement, comprising a lamp holder, a first contact piece, a second contact piece and a cord, wherein said lamp holder is such designed as to be integrally molded together. Said first contact piece and second contact piece may contact each pole of the bulb respectively, and one end of each has a sharp point for piercing the covering of the cord while contacting the core of the cord to achieve good conductivity, and said second contact piece has a proper number of projecting points at intervals equivalent to the pitches of the bulb thread to substitute for the conventional lamp holder thread.

  • Patent number: 5025997
    Abstract: Disclosed is a motor stator winding method and apparatus particularly suitable for multi-phase synchronous automatic winding of a multi-phase motor stator. The motor stator, after being held with a stator fixture, may be accurately rotated through a predetermined angle as required with a rotating device such as a timing belt and a pulley. Each of the multi-phase wires may be carried to two extremities externally of the two longitudinal ends of the motor stator with a wire carrying apparatus, capable of periodically moving through the central hole of the motor stator, and then caught with a wire feeding apparatus disposed externally of each longitudinal end of the motor stator and properly fed into the wire slots of the motor stator so as to perform a synchronous automatic winding operation for a multi-phase motor stator.
