    Abstract: This invention is directed to prevention of setting a component feeding unit set with other storage member than a storage member storing same type of components as components in shortage in an electronic component mounting apparatus. A component mounting apparatus sends notice information about component shortage to a control computer when a number of electronic components in a storage member reduces and reaches a level for sending the notice information of component shortage during mounting operations. The control computer stores the notice information, and sends the notice information to a monitor computer to display this information on a monitor. A new storage member having the corresponding components is set in the component feeding unit based on the displayed notice information, and an operator inputs information A about which component feeding unit is set with the storage member and which components are stored in the storage member set in the component feeding unit.

  • Patent number: 6874226
    Abstract: A circuit board pallet with an improved securement pin and component positioning arms is disclosed. The improved pin of the present invention is cylindrical pin with an enlarged head. A countersunk hole is drilled in the bottom of the pallet to accommodate the pin. The pin is inserted into the countersunk hole and secured with a high-temperature epoxy resin. The epoxy holds the pin securely in place and keeps the pin from moving up or down. The present invention also comprises at least one arm affixed at one end to a swivel joint. The swivel joint allows the arm to rotate about a vertical axis. The upper portion of the swivel joint is hinged such that the arm can rotate about a horizontal axis. The combination of movement about the horizontal and vertical axis allows the arm to be positioned at any point over the pallet.

    Abstract: A heat sink base (10) includes a rectangular body (11) made of aluminum and a circular core (12) made of copper. The body defines a circular through opening (111). A diameter of the opening is slightly less than a diameter of the core. The core is attached within the body according to the following steps: a) pressing the core into the through opening of the body; b) stamping the core to cause it to plastically deform in radial directions and thereby become firmly combined with the body; and c) removing any burring of the core flowing out from the opening such that surfaces of the core and the body are coplanarly smooth.
