    Abstract: A tool accelerator is disclosed that is cooperatively disposed in a stamping and forming machine that is adapted to operate on a strip of relatively hard material. The tool accelerator generally includes a trigger punch having a proximal end and a distal end. A tool is coupled to the proximal end of the trigger punch and is adapted to perform work on a strip of relatively hard material. A spring is disposed between a portion of the stamping and forming machine and the proximal end of the trigger punch, the spring being capable of being compressed by a predetermined amount in response engagement of the distal end of the trigger punch with the strip of relatively hard material.

    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.

    Abstract: An improved contact for use in a high density chip carrier socket mounted on a circuit member which utilizes a cover which to wedge the leads of the chip carrier into electrical engagement with a respective contact. A tool receiving recess is incorporated into the contact so that the forces exerted on the socket while pressing the cover into place can be opposed, minimizing the forces exerted on the connection between the socket and the circuit member, typically a solder joint. Providing a tool, that operates from one side of the circuit member, in order to press the cover into place while engaging the contact recess to oppose the insertion related forces, which can also pull the cover from the contacts, without exerting significant forces on the connection, by engaging a lip in the cover while pressing on the carrier.

    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. The ferrule main body is then positioned within a ferrule receiving opening of a central fixture such that locating pins of the central fixture are positioned within the pin slots. The fiber receiving cavity is then populated with a plurality of optical fibers which are accurately located using a plurality of combs over the ends of the optical fibers which protrude from the mating face. Finally, the fiber receiving cavity is filled with an encapsulant.

    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. The length of the plug contact 10 can also changed because the plug contact solder tail 56 is bent into its final position after the plug contacts 10 are mounted on the plug housing 12.
