Accretech
The Accretech APM 90 A is a semiconductor prober for test and probe work. The Accretech APM 90 A uses a TSK hot chuck, a manually clamped 200 mm PC adapter, and an AVME 127 CPU. The Accretech APM 90 A supports 6-inch and 8-inch wafers.[1][2]

The APM 90 A is used for chip probing and process control monitoring.[8]

Machines of this class can test a wide range of semiconductor devices, including logic, memory, analog, and mixed-signal integrated circuits, as well as discrete components like diodes and transistors.
Many probing systems in this class incorporate a thermal chuck that can heat or cool the wafer over a controlled temperature range, enabling device characterization under specified thermal conditions.
Throughput depends on factors like stepping speed, test time per device, and probe card configuration; class-level specifications are determined by the tester and handler integration.
Probing systems of this class are typically designed to accommodate a range of wafer diameters, with stage travel and chuck size matched to the specific platform, though exact sizes are model-dependent.
