Publication number: 20130141135Abstract: 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: January 30, 2013Publication date: June 6, 2013Applicant: Aehr Test SystemsInventors: Donald P. Richmond, II, Kenneth W. Deboe, Frank O. Uher, Jovan Jovanovic, Scott E. Lindsey, Thomas T. Maenner, Patrick M. Shepherd, Jeffrey L. Tyson, Mark C. Carbone, Paul W. Burke, Doan D. Cao, James F.

Publication number: 20120223729Abstract: The invention relates to a tester apparatus of the kind including a portable supporting structure for removably holding and testing a substrate carrying a microelectronic circuit. An interface on the stationary structure is connected to the first interface when the portable structure is held by the stationary structure and is disconnected from the first interface when the portable supporting structure is removed from the stationary structure. An electrical tester is connected through the interfaces so that signals may be transmitted between the electrical tester and the microelectronic circuit to test the microelectronic circuit.Type: ApplicationFiled: May 17, 2012Publication date: September 6, 2012Applicant: Aehr Test SystemsInventors: Steven C. Steps, Scott E. Lindsey, Kenneth W. Deboe, Donald P. Richmond, II, Alberto Calderon
