Patent number: 6277711Abstract: Semiconductor dice from a scribed wafer are first separated by a stretched cloth. The dice on the stretchable cloth are then lined up with a target unit and transferred by pressure to a target unit to form a matrix. The pressure can be exerted by pressing individually the dice from the stretchable cloth to the target unit. Alternatively, the dice from the stretchable cloth can first be transferred to a transfer unit before being compressed to the target unit. The transfer unit may also be a perforated board to the hold the dice in place before the dice are soldered to the target unit.Type: GrantFiled: January 8, 2001Date of Patent: August 21, 2001Inventor: Jiahn-Chang Wu

Patent number: 6272739Abstract: In handling electronic components during manufacturing or other processing, circuit devices are retained within a dual in-line processing (DIP) tube by inserting and securing DIP pins at each end of the DIP tube. The DIP pin apparatus inserts DIP pins into holes of DIP tubes by pressing a DIP pin positioned within a lower slot of a lower plate of the apparatus into a hole of a DIP tube. The DIP pin apparatus removes DIP pins from the holes of DIP tubes by lifting a DIP pin from under its head and removing the DIP pin from the DIP tube. By using the DIP pin apparatus in the handling of electronic components, the adverse effects of operator fatigue, component damage, and production inefficiencies are reduced.Type: GrantFiled: November 22, 1999Date of Patent: August 14, 2001Assignee: Lucent Technologies, Inc.Inventor: Gary M. Kimmel

Patent number: 6269532Abstract: A device for detaching a suspension assembly, adapted to support a head, staked to an actuator arm of an actuator block of a disc drive. The device includes an expandable device operable between an insertion dimension and a deswaging dimension having a flanged end defining a deswaging surface for forcing the stake from a hole of the actuator arm. In the insertion dimension, the device being sized for insertion through channels of tubular stakes for placement relative to an extended end of the stake. The device being expanded to the deswaging dimension, so that the deswaging surface of the flanged end aligns with an end surface of the stake for removing the stake from the actuator block.Type: GrantFiled: October 8, 1997Date of Patent: August 7, 2001Assignee: Seagate Technology LLCInventor: Eyvand Ernest Toensing

Patent number: 6269535Abstract: A scissors-like handle tool manipulates a ZIF socket having a cover slidably engaged with a bottom, between a loosened status and a tightened status. The handle tool comprises a first lever arm pivotably connected to a second lever arm. The handle tool is operated by encountering two lower ends of the first and second lever arms with two movable sides of the socket via a pivot operation of the handle tool thereby moving the cover of the ZIF socket along the bottom.Type: GrantFiled: September 4, 1998Date of Patent: August 7, 2001Assignee: Hon Hai Precision Ind. Co., Ltd.Inventors: Robert G. McHugh, Nick Lin, Robert Yang

Publication number: 20010010119Abstract: An apparatus which reduces the surface area with which a carrier film adheres to a die, including a plate member including laterally-spaced supports. Preferably, the apparatus also includes a vacuum source operatively connected to the plate member. Upon placement of a carrier film having an array of semiconductor dice adhered thereto onto the plate member, the dice are proximate the supports. The vacuum pulls air from the spaces between the supports, which partially releases the carrier film from the bottom surface of at least some of the dice. The apparatus may also include a die removal mechanism such as a vacuum collet type die pickup mechanism, an extendable member die plunge-up mechanism, or a combination thereof. The present invention also includes a method for reducing the surface area with which a carrier film adheres to a die to facilitate removal thereof.Type: ApplicationFiled: January 30, 2001Publication date: August 2, 2001Inventors: Warren M. Farnworth., Rockwell Smith

Patent number: 6268991Abstract: An electronic circuit interruption device having a plurality of protection, indication and control options includes a dedicated printed circuit board having electrical connection with operating circuits controlling each of the several options. Electrical connections between the operating circuits and the circuit interruption controller is made through corresponding dedicated resistors. Option selection is obtained by removal of resistors connecting with non-selected circuits on the printed circuit board.Type: GrantFiled: June 25, 1999Date of Patent: July 31, 2001Assignee: General Electric CompanyInventors: Joseph Criniti, Javier I.

Patent number: 6216339Abstract: A tool-actuated ejector for extracting electronic modular components. The ejector, which functions as a levered cam, has a body with a first end, a second end and a pivot located intermediate the first and second ends. A tool-receiving socket mounts at the second end. A tool, such as a screwdriver with a blade that matches the shape of the socket, actuates the ejector by applying a force to the socket. A cam, located at the first end, engages the electronic modular component. To provide a mechanical advantage, the distance between the tool-receiving socket and the pivot, which constitutes one lever arm, is greater than the distance between the cam and the pivot, which constitutes a second lever arm. In addition, a shock absorber mounts on the body and gliders extend below the body to provide stability and balance to the ejector. The ejector mounts in a casing having a tool passage that communicates with the tool-receiving socket and the exterior of the casing.Type: GrantFiled: May 8, 1998Date of Patent: April 17, 2001Assignee: 3Com CorporationInventor: Daniel Rich
