Publication number: 20200300908Abstract: 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: June 11, 2020Publication date: September 24, 2020Applicant: AEHR TEST SYSTEMSInventors: Steven C. Steps, Scott E. Lindsey, Kenneth W. Deboe, Donald P. Richmond, II, Alberto Calderon

Publication number: 20190339303Abstract: A method of testing an integrated circuit of a device is described. Air is allowed through a fluid line to modify a size of a volume defined between the first and second components of an actuator to move a contactor support structure relative to the apparatus and urge terminals on the contactor support structure against contacts on the device. Air is automatically released from the fluid line through a pressure relief valve when a pressure of the air in the fluid line reaches a predetermined value. The holder is moved relative to the apparatus frame to disengage the terminals from the contacts while maintaining the first and second components of the actuator in a substantially stationary relationship with one another. A connecting arrangement is provided including first and second connecting pieces with complementary interengaging formations that restricts movement of the contactor substrate relative to the distribution board substrate in a tangential direction.Type: ApplicationFiled: July 15, 2019Publication date: November 7, 2019Applicant: Aehr Test SystemsInventors: Scott E. Lindsey, Junjye Yeh, Jovan Jovanovic, Seang P. Malathong

Publication number: 20180372792Abstract: 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: September 4, 2018Publication date: December 27, 2018Applicant: Aehr Test SystemsInventors: Donald P.
