This document describes the fabrication and use of multilayer ceramic substrates, having one or more levels of internal thick film metal conductor patterns, wherein any or all of the metal vias intersecting one or both of the major surface planes of the substrates, extend out of the surface to be used for making flexible, temporary or permanent interconnections, to terminals of an electronic component. Such structures are useful for wafer probing, and for packaging, of the semiconductor devices.

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.

A probe card assembly is disclosed. The probe card assembly includes a probe card plate, a probe core, and an expansion gap defined in the probe card plate. The probe core includes a bonding portion for fixing the probe core to the probe plate. The expansion gap surrounds the probe core. Another probe card assembly is disclosed. The another probe card assembly includes a probe card plate, a tube, and a probe core. The tube is configured to be inserted into an opening of the probe card plate and configured to be securely fixed to the probe card plate. The probe core includes a bonding portion for fixing the probe core to the tube.

A system for monitoring and controlling an IC testing machine includes a vibration sensor, a sensor interface, and a processor coupled to the sensor interface. The vibration sensor is in mechanical communication with an IC testing machine to develop an electrical vibration signal representing mechanical vibrations generated by the operation of the IC testing machine. The sensor interface processes the vibration signal to develop vibration data that can be processed by the processor to determine whether the vibration data is indicative of an operational anomaly and, if so, to generate a machine control signal to correct an operation of the IC testing machine. Multiple vibration sensors can be used to increase the amount of vibration data available for analysis.

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.
