Probe card having adjustable high frequency signal transmission path for transmission of high frequency signal

摘要

A probe card for high-frequency signal transmission includes a circuit board with transmission lines, a plurality of probes, and a signal path adjuster having first lead wires with a same length respectively connected between the transmission lines and the probes. Each first lead wire is selectively replaceable by a second lead having a length different from that of the first lead wire. As a result, a first high-frequency signal transmitting from one transmission line through the associated first lead wire to the associated probe and a second high-frequency signal transmitting from another transmission line through the associated second lead wire to the associated probe may have a same output timing when the first and second high-frequency signals are synchronously inputted into the circuit board.

1. A probe card for high frequency signal transmission, comprising:
a circuit board on which a plurality of transmission lines are arranged; a probe set having a plurality of probes; and a signal path adjuster having a plurality of lead wires each having two ends, the lead wires comprising first lead wires having a same first length and second lead wires each having a length different from that of the first lead wires; wherein the two ends of at least one of said first lead wires are electrically connected with one said transmission line and one said probe respectively, and the two ends of at least one of said second lead wires are electrically connected with another said transmission line and another said probe respectively, such that a first high frequency signal transmitting from the one said transmission line through the associated first lead wire to the associated probe and a second high frequency signal transmitting from the another said transmission line through the associated second lead wire to the associated probe have a same output timing when the first and second high frequency signals are synchronously inputted into the circuit board.
