P5D SEMI-AUTOMATIC SQUARE SUBSTRATE PROBE SYSTEM
PWS’ P5-D Prober System is a fully automated production handling system specifically designed to handle square substrates. The P5-D is a member of the field-proven family of Pacific Western System’s P5 prober systems - fully automated production substrate handling systems that deliver high accuracy, high performance and high reliability probing.
The P5-D probe system comes standard with a frictionless Air Bearing Motion System (ABMS) for X-Y positioning. The ABMS is a lead-screw driven stage that moves on a friction-free film of air - the stage is supported by air only during movement, and sits on a precision lapped surface at rest. The ABMS is specifically designed for high precision micro stepping of semiconductor wafers and similar substrates. The air bearing motion system, combined with PWS’ in-house manufactured lead screws, ensures superior accuracy, repeatability, and mechanical stability.
The P5-D employs an upgraded loader design to permit handling of the heavier gram loads that thick substrates present. Substrate materials with which the P5-D excels include silicon, ceramic, and most metals and quartz.
The P5-D is also equipped with ProbeCommander, PWS’ Real Time Wafer Mapping software. ProbeCommander, a leading edge NT-based operating environment, significantly simplifies the test and production engineer’s tasks. For example, bin result maps from production tests can be easily re-probed for failures. An engineer can select and move to any tested bin: the moves can be either automatic step-and-repeat or under cursor/mouse control. If needed, unique stepping patterns can be created to step within individual dies.
ProbeCommander includes the following features:
