ABOUT : Probing with a probecard & Mapping
The probecard will allow accessing several pads at the same time. It my be usefull for device biasing while testing, or full testing.
A manual or semi-automatic probe station can integrate a probecard and micro-positioners, a chip can them be tested for internal circuitry while biasing is on.
- For repetitive sub-routine on a die, a motorized positioner can be used to automatically contact the previously programmed points.
- For only few contacts access, the probecard can be wedge type and is then mounted onto a positioner, DC and RF signals can be mixed
Microworld also offers production probecards mounted on automatic probers.
