- step S 07 If the displacement is equal to or greater than the predetermined value T (step S 07 — Yes), the servo motors 7 1 1, 7 2 2 and 7 3 2 of the probe card stage 7 are driven to drive the X base 7 2 Move the Y base 7 3 or the card ring 7 3 5 to move the probe card 8 in the X and Y directions and / or vertically
- the positional deviation is corrected by rotating around the axis (step S08).
- step S07—No when the displacement is less than the predetermined value T (step S07—No), the servomotors 41a, 41b, and 41c of the pusher stage 4 are driven to drive the top table. Move the pusher nit 3 and the pusher nit 3 to correct the misalignment by moving the carrier tape 5 sucked by the suction plate 3 4 in the X-axis and Y-axis directions and / or by rotating it around the vertical axis (step SO 9).
- the probe card 8 when the amount of displacement is large (T or more), the probe card 8 is moved by the probe card stage 7 to correct the displacement, so that there is no problem as described above.
- the value of T varies depending on the size of the TCP (particularly, the perforation size in the X-axis direction / test pad size) and the like, but may be appropriately set in consideration of the risk of damage to the TCP and the carrier tape 5 as described above. .
- the value of T as the amount of displacement (degrees) around the vertical axis is within 0.1 (degrees).
- step S10 After the displacement is corrected in step S08 or step S09, the servo motor 31 of the pusher unit 3 is driven, and the suction plate 34 is further moved through the pusher body 33 to the Z position. Move down the axis. The suction plate 34 on which the carrier tape 5 has been suctioned is lowered to the contact position, and the TCP is pressed against the probe 81 of the probe card 8 (step S10).
- the TCP handler 2 determines whether or not the tested TCP is the last device (step S11), and if it is the last device (step SI1—Yes), The main operation ends. On the other hand, if it is determined that the device is not the last device (step S11-No), the servo motor 31 of the pusher 3 is driven, and the suction plate 34 is moved via the pusher body 33. Is moved upward in the Z-axis, and the pusher stage 4 and the probe card stage 7 are moved to the registration positions (step S12). Then, the suction plate 34 stops the suction of the carrier tape 5 to release the carrier tape 5, and further moves upward in the Z-axis (step S13). Thereafter, the process returns to step S02.
- the structures of the pusher stage 4 and the probe card stage 7 are not particularly limited, and the structures of both may be interchanged, or both may have the same structure.
- the probe card stage 7 may be omitted, and the displacement may be corrected only by the pusher stage 4. Even in this case, since the carrier tape 5 can be rotated around the vertical direction by the pusher stage 4, the position of the TCP and the probe 81 can be compared with the two-axis control only in the X-axis and Y-axis directions. The alignment can be performed accurately.
- the pusher stage 4 may be omitted, and the displacement may be corrected only by the probe card stage 7.
- the probe card stage 7 allows the probe card 8 to move in the X-axis and Y-axis directions and to rotate around the vertical axis during the actual operation of the TCP handler 2, so that TCP and It is possible to reduce the occurrence of contact failure with the bus 81.
- the TCP handling apparatus or the positional deviation correction method according to the present invention it is possible to accurately perform the alignment between the TCP and the contact portion, and to reduce the occurrence of contact failure. That is, the TCP handling apparatus and the position shift correction method according to the present invention are useful for performing a TCP test accurately, reliably, and efficiently.
