  • Patent number: 7006738
    Abstract: The array ferrule of the present invention has a main body having a fiber receiving cavity which extends therethrough from a mating face to a rear end. A pair of pin slots is formed in opposing side walls of the main body being precisely located with respect to the fiber receiving cavity. In communication with each pin slot is a retention member slot for receiving a pin retention member. A plurality of fibers is precisely positioned within the fiber receiving cavity and an encapsulant substantially surrounds the fibers to substantially fill the fiber receiving cavity. A method of making the array ferrule begins with providing a ferrule blank having a pair of preformed slots extending inward from the opposing side walls. The blank is precisely aligned on a mandrel which is placed within the fiber receiving cavity. Pin slots are broached in each side surface in the area of the preformed slots to form the ferrule main body.

  • Patent number: 6146438
    Abstract: An apparatus and method of forming balls includes a metering device 2, a melting device 14 and a cooling device 20. The metering device 14 stamps a desired volume of solid material in the form of a slug 12 which passes through the melting device 14 where it is caused to levitate and transform state from a solid to a molten liquid. The molten liquid material 13 is released from the melting device 14 and descends through the cooling device 20 where it transforms state once again from a molten material to a solid material while maintaining a ball shape. A forming gas is passed over the molten material 13 in a direction opposite to the falling molten material 13. The balls 15 are finally cooled in a cooling bath 32.

  • Patent number: 5868019
    Abstract: A stamping and forming machine (10) is disclosed having a feed mechanism for incrementally feeding a strip of material (32) along a feed path and momentarily stopping the strip in proper position within tooling (20, 22) during the stamping and forming operation. The feed system includes a feed drum (36) and is arranged to move between a driving position where the feed drum (36) is in engagement with the strip of material (32) for effecting the movement thereof along the feed path and a remote position out of feeding engagement therewith. A misfeed detection and feed release mechanism is provided for moving the feed drum (36) from the driving position to the remote position upon detection of a misfeed where the strip of material (32) is displaced from the proper position. The feed drum (36) is spring loaded toward the remote position. A first sear (190) is in engagement with the feed drum so that it is held in the driving position against the urging of the spring (174).

  • Patent number: 5816482
    Abstract: The present invention is directed to an apparatus and method for attaching balls to a substrate for forming a ball grid array. The apparatus consists of two pole pieces, a magnetizing coil, and an excitation coil. The first pole piece has an alignment plate having a plurality of openings, and a plurality of tips which can be magnetized by the magnetizing coil to attract a ball into each opening. Once the balls are attracted into the openings, excess balls are removed and the substrate is aligned with the balls such that each ball is in contact with a respective pad on the substrate. The first pole piece having the balls and substrate position thereon is then placed into a receiving area of the second piece. An excitation coil is excited with a high frequency signal to heat the balls and reflow solder that has been previously applied thereto. The assembly is then cooled and removed from the device and the ball grid array is complete.

  • Patent number: 5700151
    Abstract: An electrical connector assembly 2 for use in connecting parallel printed circuit boards includes a receptacle connector 4 and a plug connector 6. The receptacle connector 4 includes receptacle contacts 8, each of which includes a surface mount solder tail 16 and a mating contact section in the form of a resilient arm 26 on opposite sides of a sealing pad 18 that seals a contact insertion opening 38 when the receptacle contact 8 is fully inserted. The mating contact portion is therefore isolated from contaminating materials, such as solder flux during surface mount solder operations. The height of the connector assembly 2 can be adjusted by using plug connectors 6 of different heights with a universal receptacle connector 4. The height of the side walls 60 on the plug housing 12, between a plug mating section and contact retention section is changed for different plug connector heights.
