Top Products Wafer Prober PCP-102WS

Double Sided Wafer Prober



The PCP-102WS is a high precision prober designed to contact both sides (double side) of wafer.
By adopting PFC original XY Compensation and Profiling function, PCP-102WS can compensate the position even if a wafer is warped.
Accurate RDS (on-resistance) is measured by making Kelvin connection at the drain side on the back of wafer and adjusting its drain-sense-position to the source-sense-position.


Contacts both sides (double side) of wafer
Effective position compensation for the warpage of wafer
Successful record 100% of Alignment for customers' products (Record only in Japan)
Measures the accurate RDS (on-resistance)
Probing at more than two points by moving in a chip (Micro Probing)
Large current/High voltage probing is supported by the wafer clamp system with ceramic blade
Low noise: More than -80dB on the chuck
(Reference Value: 30KHZ to 30MHZ Loop ANT actual measurement)
High rigidity cabinet made by the iron surface plate and the welding frame realizes low vibration
