Probe Alignment Method and System

Abstract

A probe alignment method is applied to a probe alignment system. The system includes a control circuit, a working platform, a first probe tray, a second probe tray, and a first and a second probe extraction device electrically coupled to the control circuit. The working platform has a working area to hold a probe card with multiple receiving holes. The first and second probe trays are respectively supported on both sides of the working area. Each probe tray holds a plurality of probes, each probe having a head and a... The probes in the first needle tray have a tail and a single-sided stop located between the head and the tail. The heads and single-sided stops of the probes in the second needle tray point to a first axial direction and a first radial direction, respectively. The heads and single-sided stops of the probes in the second needle tray point to a second axial direction and a second radial direction, respectively. The first axial direction and the second axial direction are opposite in direction, and the first radial direction and the second radial direction are opposite in direction. The first needle-picking device has a pair of first grippers, and the second needle-picking device has a second gripper. The control circuit is used to... A program is executed to implement the probe alignment method, and the probe alignment method includes the following steps: performing a first needle insertion operation, which includes: driving one of the first grippers to grasp the tail of a first target probe among the probes in the first needle tray; driving one of the first grippers to perform a flipping operation so that the head of the first target probe points to the second axial direction and the one-sided stop of the first target probe points to the second radial direction; and driving the other gripper of the first gripper to grasp the first target probe. The head of the needle is inserted into one of the receiving holes of the probe card with the tail facing down and the one-sided stop pointing in the second radial direction; and a second needle insertion operation is performed, which includes: driving the second gripper to grasp the head of one of the probes of the second needle tray, and inserting the second target probe into one of the receiving holes of the probe card with the tail facing down and the one-sided stop pointing in the second radial direction.
