In other words, when changing the TCP type, testing a different production lot of TCP, or changing the probe card 8, the TCP test pad and the probe 81 of the probe card 8 should contact each other.
- FIG. 8A to FIG. 8C are flowcharts showing the initial setting operation of the TCP handler 2.
- the TCP handler 2 When the TCP handler 2 starts the initial setting operation, it transports the reference TCP to the test position (step S01), and the second camera 6b uses the second camera 6b to transmit a plurality of TCPs located at one end of many test pads. Take a picture of the test pad (step S02).
- the second camera 6b captures the power of the TCP test pad.
- the present invention is not limited to this.
- the predetermined mark attached to the TCP may be captured. However, a characteristic part such as a corner of the package may be photographed.
- the image processing unit of the TCP handler 2 uses the coordinate data (X, Y) pdl of each of the center portions of the plurality of test pads included in the first image. Get dl (step S03). In addition, each coordinate data obtained by this operation shall be mapped to the coordinate system of the camera stage 61.
- the TCP handler 2 moves the second camera 6b by the camera stage 61, and a plurality of test pads located at another end of the multiple test pads in the TCP by the second camera 6b. (Step S04). Based on the captured image (second image), the image processing unit of the TCP handler 2 acquires coordinate data (X, Y) of each of the central portions of the plurality of test pads included in the second image ( Step S05).
- the image processing unit of the TCP handler 2 acquires the acquired coordinate data (X, Y) and (X, Y pdl pdl pd2 p
- the angle (first angle 0) of the straight line passing through the position coordinates of the center of the test pad included in (the test pad array) and the straight line in the X-axis direction (horizontal line in FIG. 7) is calculated (step S06).
- the TCP handler 2 moves the second camera 6b with the camera stage 61, and photographs the feature portions 84 corresponding to the plurality of test pads included in the first image with the second camera 6b.
- the image processing unit of the TCP handler 2 obtains cl cl by obtaining the coordinate data (X, ⁇ ) of the feature portion 84 included in the third image (step S08). Then, cl cl associated with the coordinate data (X, Y) of the feature 84
- the contact surface of the probe 81 cannot be captured by the second camera 6b, but via the coordinate data (X, Y) of the feature 84 that can be clearly captured by the second force camera 6b.
- the coordinate data (X, Y) of the contact surface of the probe 81 can be estimated with high accuracy.
- the TCP test pad and the probe 81 of the probe card 8 can be aligned extremely accurately.
- the TCP handler 2 moves the second camera 6b by the camera stage 61, and photographs the feature portions 84 corresponding to the plurality of test pads included in the second image by the second camera 6b (step) S 10). Based on the captured image (fourth image), the image processing unit of the TCP handler 2 acquires the coordinate data (X, Y) of the feature unit 84 included in the fourth image (c2 c2
- Step SI 1 c2 c2 associated with the coordinate data (X, Y) of the feature 84
- the image processing unit of the TCP handler 2 determines the probe 81 pbl pbl pb2 corresponding to the third image based on the coordinate data (X, Y) and (X, Y) of the estimated contact surface of the probe 81. pb2
- the TCP handler 2 calculates the difference value ⁇ between the first angle 0 and the second pdl obtained in steps S06 and S13 (step S14). If the absolute value of the obtained difference value ⁇ is larger than the predetermined value D (step S15, Yes), the TCP handler 2 rotates and moves the probe card stage 7 based on the difference value ⁇ ( In step S16), when the absolute value of the difference value ⁇ is equal to or smaller than the predetermined value D (step S17, Yes), the rotational movement of the probe card stage 7 is stopped (step S18). On the other hand, if the absolute value of the difference value ⁇ is equal to or smaller than the predetermined value D in step S15 (step S15, No), the process proceeds to step S19 without rotating the probe card stage 7.
- the TCP handler 2 moves the second camera 6b by the camera stage 61, and again captures the characteristic portion 84 corresponding to the plurality of test pads included in the first image by the second camera 6b. (Step S19). As a result, even if the probe card 8 moves around the vertical axis in step S15 and the target probe 81 is out of the field of view of the second camera 6b, it is possible to take an image again.
- the image processing unit of TCP Handler 2 Based on the (fifth image), coordinate data (X, Y) c3 c3 of the feature portion 84 included in the fifth image is acquired (step S20). Then, the coordinate data (X, Y) of the contact surfaces of the plurality of probes 81 is estimated by adding c3 c3 related to the coordinate data (X, Y) of the feature portion 84 (pb3 pb3
- the TCP handler 2 moves the second camera 6b by the camera stage 61, and re-photographs the characteristic portions 84 corresponding to the plurality of test pads included in the second image by the second camera 6b. (Step S22). Based on the captured image (sixth image), the image processing unit of TCP handler 2 uses the coordinate data (X, Y c4 c) of the feature 84 included in the sixth image.
- the TCP handler 2 performs the coordinate data (X 1, Y 2) and (pdl dl
- ⁇ and ⁇ are calculated (step S25). If the absolute value of the obtained difference value ⁇ , ⁇ is larger than the predetermined value P (Yes in step S26), the TCP handler 2 moves the probe card stage 7 in the X-axis direction based on the difference value ⁇ , ⁇ . And move in the Z or Y axis direction (Step S27), and when the absolute value of the difference value ⁇ , ⁇ is less than or equal to the predetermined value P (Step S28, Yes), stop moving the probe card stage 7 (Step S29), the position of the probe card stage 7 is registered (Step S30).
- step S26 if the absolute value of the difference values ⁇ and ⁇ is equal to or smaller than the predetermined value P in step S26 (step S26, No), the position without moving the probe card stage 7 is registered (step S3). 0). In this way, TCP handler 2 finishes the initial setting.
- the alignment between the TCP test pad and the probe 81 of the probe card 8 is performed automatically and using the characteristic portion 84. Can be done accurately.
- the alignment of the TCP test pad and the probe 81 of the probe card 8 is performed by sequentially performing the alignment around the vertical axis and the alignment in the X-axis direction and the vertical axis direction separately. It can be done more accurately. Gatsutsu Thus, the initial setting of TCP handler 2 can be performed efficiently in a short time.
- the alignment of the TCP and the probe card 8 around the vertical axis and the alignment in the plane direction are performed separately, but the present invention is not limited to this. Both may be performed simultaneously.
