  • Patent number: 8616907
    Abstract: A test socket may include a socket frame, a plate, a socket pin and a link. The socket frame may have a slot configured to accept an object. The plate may be free to move in the slot along an inserting direction of the object to support a lower surface of the object. The socket pin may be movably arranged in a direction substantially perpendicular to the inserting direction of the object. The socket pin may selectively make contact with a tab of the object. A link may be pivotally connected to the socket pin and the plate. Thus, the socket pin of the test socket may avoid dragging along the tab of the object during insertion, and accordingly, the tab of the object may avoid damage.

  • Patent number: 7576437
    Abstract: Example embodiments may be directed to a printed circuit board having an insulating substrate, pads disposed on the surface of the insulating substrate, a solder resist, and a solder moving portion. Leads of a semiconductor package may be mounted on the insulating substrate. The pads to which the leads of the semiconductor package are connected may be disposed on the surface of the insulating substrate. The solder resist layer may cover the insulating substrate, but may also contain openings exposing at least a portion of the pads to which the leads of the semiconductor package are connected. During the process by which each semiconductor lead is connected to a pad, the solder moving portion on the pad may allow an adhesion solder coating each of the leads of the semiconductor package to move towards a shoulder portion of the semiconductor package leads.

  • Patent number: 7061768
    Abstract: An open socket, into which a module can be inserted, may include: a body into which the module is insertable; a pin to contact an electrical connection member of the inserted module, the pin serving as at least a part of an electrical signal path to/from the module upon insertion thereof; an elastic biasing member to exert an elastic biasing force to cause the pin to contact the module; and at least one lower support to limit insertion depth as being a depth at which a lower portion of the inserted module comes to rest upon the at least one lower support; the body and the at least one lower support being constructed and arranged to provide a gap adjacent the at least one support, which leaves an area of the socket underlying the lower portion of the inserted module open to the outside.

  • Patent number: 6062799
    Abstract: An apparatus for automatic loading or unloading printed circuit boards (PCBs) for semiconductor modules is disclosed. The apparatus employs an elastic jig carrier into which the PCBs are loaded. The jig carrier includes movable clamps for fixing the PCBs by elastic force. A jig opener of the apparatus applies opening force, in the reverse direction of the elastic force, to the movable clamps so that the PCBs can be loaded into or unloaded from the jig carrier by a picker. The jig carrier is transferred along a conveyor belt, while the PCBs are supplied from a PCB stage such as a tray to the jig carrier. The apparatus may further comprise a gripper and a rotator. The gripper grips the upright PCBs and the rotator rotates them to be horizontal, so that the picker can pick up the horizontal PCBs. The apparatus may also comprise an aligner for exact alignment of the PCBs in the jig carrier. A method for loading or unloading the PCBs into or from the jig carrier is also disclosed in connection with the apparatus.

  • Patent number: 5927504
    Abstract: An apparatus for carrying plural printed circuit boards (PCBs) for semiconductor modules is disclosed. The apparatus comprises a main frame which is formed with an inside space for the PCBs. The main frame includes receivers for supporting one shorter edge of the PCBs. A clamp frame joined to the main frame includes a support plate for the other shorter edge of the PCBs. Movable clamps are elastically connected to the clamp frame so as to push the PCBs by elastic force when the PCBs are loaded into the apparatus. A adjustable mounting such as a slot or holes is provided in the main frame for fasteners joining two frames each other. Therefore, the apparatus can carry the PCBs of different size. The elastic connection between the clamp and the clamp frame is preferably made by slide bars and elastic members. Clamp holes, sub-walls, partition walls, hollow corners, and so forth may be preferably provided for the apparatus.
