Abstract:

A blade probe card includes a plurality of blades that each includes a first end connected to a printed circuit board and a second end. A probe member is attached to the second end of each blade and extends outward to make contact with a device under test. A ground member is attached to the second end of each blade. The blade probe card also includes a common ground member that is separate from the printed circuit board and coupled to the ground member of each blade. Each blade may also include a first conductive signal trace and two or more conductive ground traces formed on a surface of each blade. The first conductive signal trace electrically connects the probe member to a contact on the printed circuit board. The two or more conductive ground traces are adjacent to the conductive signal trace and reduce crosstalk between the blades.
