- the operations of steps S10 to S130 in FIG. 14 described above are repeated until the IC chip is held on 113.
- one of the movable heads 4 13 of the IC moving device 4 10 performs the positioning and moving operation of the IC chip
- the other movable head 4 13 is also moved with respect to the same test plate 11. The same operation is performed, and the mutual operation time is absorbed, and the through-put in the electronic component test apparatus 1 is improved.
- the test plate 110 When the IC chips are placed on all the holding parts 1 13 on the test plate 110, the test plate 110 is lowered by the lifting mechanism 1 24 of the plate moving device 120 and the chamber 1 It is taken in 00 and is moved to the application position 102 along the corresponding step guide rail 1 2 1. Then, when a desired thermal stress is applied to the IC chip after waiting at the application position 102 for a predetermined time, the IC chip is moved to the test position 103 and raised by the pressing mechanism 125 so that the test plate 110 is raised. As shown in Fig. 26, the IC chips held in each of the holding portions 1 13 of the 0 are pressed simultaneously against the corresponding contact portions 151 of the test head 150, and the test is performed. .
- the result of this test is the address determined by, for example, the identification number given to the test plate 110 and the number of the IC chip assigned inside the test plate 110, and is stored in the storage device of the electronic component test device 1. It is memorized.
- the first side surface 113a of the holding portion 113 of the test plate 110 faces the first guide surface 1 around the contact portion 151. 5 2 and abut the second side 1 1 3 b of the holding portion 1 13 of the test plate 110 with the second side around the contact portion 15 1.
- the guide surfaces 15 3 and 3 are abutted so as to follow them, and at the same time, the springs 1 16 apply a pressing force in the respective abutting directions, so that these surfaces 1 1 3 a, 1 1 3 b, 1 5 2 and 15 3 are brought into close contact with each other, and the corresponding holding portion 113 of the test plate 110 is positioned with respect to each contact portion 151 of the test head 150.
- the distance L have L 2 from the first and second guide surfaces 1 5 2 1 5 3 in Uz de 1 5 0 to the test to the central position of the contact portion 1 5 1, Tess
- the distances L 3 and L 4 from the first and second side surfaces 1 13 a and 1 13 b to the center position P v of the holding surface 1 14 are the same.
- the IC chip is held by the holder 113 so that the center position Pv of the holding surface 1 14 and the attitude substantially match the center of gravity P H and the attitude of the input / output terminal HB.
- the first and second side surfaces 113a and 113b of the holding portion 113 of the test plate 110 correspond to the first and second guides around the contact portion 151. Positioning by the surface 152 enables the input / output terminal HB of the IC chip to be positioned relatively to the contact bin of the contact part 151 of the test head 150 When One is that.
- the tested IC chip that has been tested in the test head 150 is moved from the chamber 100 to the alignment unit 400 by the plate moving device 120, and is moved by the IC moving device 410. It is moved from the alignment unit 400 to the loader Z unloader unit 300, and is dispensed by the first IC carrier 310 of the loader / unloader unit 300 according to the test result. It is accommodated in the Kasuma tray located at 2.
- the embodiments described above are described for facilitating the understanding of the present invention, and are not described for limiting the present invention. Therefore, each element disclosed in the above embodiment is intended to include all design changes and equivalents belonging to the technical scope of the present invention.
- a BGA type IC chip in which a ball-shaped input / output terminal is derived is adopted as an example of the electronic component.
- the present invention is not particularly limited to this.
- a foil-shaped input / output terminal It is possible to test electronic components of a type that has a back surface on which the input / output terminals of the LGA and the like are not derived, and that do not hinder the application of force to the back surface. Further, in the present embodiment, the relative position and orientation of the input / output terminal with respect to the outer shape of the Ic chip were calculated.
- the present invention is not particularly limited to this, and for example,
- the first and second side surfaces of the holding portion are brought into contact with the first and second guide surfaces around the contact portion, so that the holding portion is moved relative to the contact portion.
- the present invention is not particularly limited to this.
- a guide bin is formed in the contact portion
- a guide hole is formed in the holding portion
- the guide pin is inserted into the guide hole at the time of contact.
- the holding part may be positioned with respect to the contact part.
- the present invention is not particularly limited thereto.
- the optical positioning method described above may be used, or a mechanical positioning method such as a cantilever may be used.
