  • Publication number: 20090096473
    Abstract: A testing probe including a shaft body and a plurality of claws is provided. Each cross section of the shaft body has a substantially identical shape and a substantially identical outer diameter. The claws are formed integrally with the shaft body at an end thereof. An orthogonal projection of the claws on any one of the cross sections of the shaft body is within the contour of the cross section. Contacting a solder bump on a test pad of a circuit board with the claws of the testing probe increases the test yield of the circuit board.
