Description of the Opto System Wafer Prober WPF4000

The wafer prober WPF4000 is able to handle wafers up to 4″ size. This prober electrically characterizes all the chips by contacting them from the top with probing needles. If both contacts are on the top the chips can remain on their tape while the high performance vision system with multiple cameras precisely align and monitor the measurement. If one contact is on the bottom, the chips are transferred to a gold plate serving as an electrode chuck. We can integrate your testing equipment or we would suggest one. The robust and reliable aspect of this tool has made it very successful among semiconductor manufacturing customers around the world. A very large application case is the testing of BAW and SAW filters.

FAQ

Are Larger Frames possible?

This is also fully customizable to satisfy your specific requirements. But there are many standardized options to start with. The WPF4000 set-up provides space for 4inch wafers, while the WPF6000 set-up has space to handle chips on a 6inch ring, the larger WPF8000 can handle 8 inch wafers. We can always check configurations of an custom-made machine that can handle other geometry. Just let us know your requirements.

Why is the testing equipment optional?

You may want to use the equipment you are used to work with. We would be happy to either propose an optional testing equipment package or work with you to integrate the testing equipment that you provide us from a third party.
