Patent ID: 6842023

Claim:
A probe card apparatus having a plurality of probes ( 1 A to 1 D) that are brought into contact with electrode portions ( 5 ) of an object of measurement, for performing an electrical test of the object of measurement, wherein said probes ( 1 A- 1 D) respectively include cutting blade portions ( 2 ) having a cutting edge ( 2 a ) of a shape continuous in one direction, said cutting blade portions being provided at tip end portions of said probes and being brought into contact with said electrode portions ( 5 ), respectively; at said cutting blade portions ( 2 ), said cutting edges ( 2 a ) are each formed such that each respective one of said cutting edges is respectively in a plane approximately parallel to a direction of sliding of said respective cutting edge relative to a respective one of said electrode portions ( 5 ) when each of said plurality of probes ( 1 A to 1 D) is in contact with said electrode portions ( 5 ); and each respective one of said cutting edges ( 2 a ) has a continuous shape in a height direction, said shape coming closer to said respective electrode portion ( 5 ) from a front side of said cutting edge toward a rear side of said cutting edge along the direction of sliding as each of said probes ( 1 A to 1 D) slides relative to, and with said cutting edge in contact with, said electrode portion ( 5 ).
