  • Patent number: 10718808
    Abstract: 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.

  • Publication number: 20200027799
    Abstract: A tester apparatus is provided. Slot assemblies are removably mounted to a frame. Each slot assembly allows for individual heating and temperature control of a respective cartridge that is inserted into the slot assembly. A closed loop air path is defined by the frame and a heater and cooler are located in the closed loop air path to cool or heat the cartridge with air. Individual cartridges can be inserted or be removed while other cartridges are in various stages of being tested or in various stages of temperature ramps.
