Publication number: 20240103068Abstract: An apparatus is described for burn-in and/or functional testing of microelectronic circuits of unsingulated wafers. A large number of power, ground, and signal connections can be made to a large number of contacts on a wafer. The apparatus has a cartridge that allows for fanning-in of electric paths. A distribution board has a plurality of interfaces that are strategically positioned to provide a dense configuration. The interfaces are connected through flexible attachments to an array of first connector modules. Each one of the first connector modules can be independently connected to a respective one of a plurality of second connector modules, thereby reducing stresses on a frame of the apparatus. Further features include for example a piston that allows for tight control of forces exerted by terminals onto contacts of a wafer.Type: ApplicationFiled: November 29, 2023Publication date: March 28, 2024Applicant: AEHR TEST SYSTEMSInventors: Donald P.

Patent number: 5518460Abstract: The combination of an endless power transmission belt construction and a pulley therefor, the belt construction and methods of making the same are provided, the belt construction having opposed inner and outer surfaces with one surface defining a plurality of longitudinally disposed and alternately spaced apart like projections and grooves that are adapted to mesh with a ribbed surface of one pulley, and a planar surface adapted to operate on a planar surface of another pulley, wherein the planar surface of the belt construction comprises a polymeric material. The polymeric material of the planar surface provides a greater tractive force on the planar surface of the pulley. The planar surface further provides means to prevent abrasive particles accumulating thereon, thereby reducing wear upon the planar surface of the pulley.Type: GrantFiled: March 22, 1995Date of Patent: May 21, 1996Assignee: Dayco Products, Inc.Inventors: Jack D. White, Jr., Kenneth D. Richmond

Patent number: 4622023Abstract: A belt pulley and method of making the same are provided, the pulley having a hub and a peripheral groove for receiving part of an endless belt therein that is to drive the pulley or be driven thereby whereby the pulley is adapted to be rotated about a longitudinal axis of the hub. The pulley has a pair of opposed facing sides defining at least part of the groove therebetween and has a pair of oppositely facing outboard sides, the sides each having an inner peripheral portion and an outer peripheral portion. The pulley has a plurality of circumferentially spaced apart and radially disposed substantially straight vanes extending outwardly from at least one of the outboard sides thereof.Type: GrantFiled: April 1, 1985Date of Patent: November 11, 1986Assignee: Dayco CorporationInventors: Terrence R. Quick, Paul M. Standley, Mark P. Foley, Anderson W. Howerton, Joseph P. Miranti, Jr., Larry R. Oliver, Gerald C. Holloway, Jr., Kenneth D. Richmond
