Abstract:
1. A method of manufacturing a probe card that electrically connects a testing device and a device under test to transmit a signal between the testing device and the device under test, the method comprising the steps of: forming a probe pin on a probe pin substrate; joining the probe pin held on the probe pin substrate to a circuit board; and cutting the probe pin to separate the probe pin substrate from the probe pin, wherein said probe pin forming step comprises the steps of: depositing a sacrifice layer on a surface of the probe pin substrate; depositing a conductive material from the surface of the probe pin substrate to a surface of the sacrifice layer to form the probe pin; and removing the sacrifice layer to form a portion in which the probe pin is separated from the probe pin substrate, and wherein said probe pin cutting step comprises the step of cutting the portion of the probe pin, which is separated from the probe pin substrate, while the remaining portion of the probe pin is joined to the probe pin substrate.
