Introducing the FormFactor Cascade PAP200 200 mm semi-automated vacuum and pressure probe system

Cascade PAP200LP from FormFactor probe system from FormFactor is the ideal probing solution for testing MEMS pressure sensors with high accuracy at above/below atmospheric air pressure. The entire 200 mm prober is integrated into a pressure chamber rated from 500 mbar to 1200 mbar absolute.

To meet the production test requirements, the PAP200LP is equipped with a highspeed 200 mm chuck stage, designed for use with standard 4.5” probe cards. The modular design of the PAP200LP enables a wide range of measurements, including I-V for piezo-resistive and C-V for capacitive pressure sensors.

The PAP200LP is equipped with a stable vibration isolating frame. The pressure chamber with topside viewport and an optical window made of quartz glass contains flanges for vacuum-tight electrical feedthroughs. The pressure control system consists of a powerful diaphragm vacuum pump, a remote controlled proportional valve for air dosage and a high-precision pressure sensor to monitor the environmental conditions.

All main functions, i.e. stage movement and pressure control, can be controlled by software. The large front door allows quick and ergonomic loading and unloading of the wafer, as well as easy probe card exchange. A swivel mechanism, which is part of the microscope station, allows convenient access to the topside lid.

The PAP200LP can be customized with a variety of instrumentation, such as video microscopes, laser cutters and Polytec’s optical motion analysis tools. Specially designed thermal chucks, with electrical and coolant bulk feed throughs, are available for the use under vacuum conditions. The PAP200LP supports a wide temperature range from -60°C to 200°C , and a dew point
sensor ensures condensation-free probing.
