Abstract:
1. An electronic device test method for testing an electronic device under test, the electronic device under test having a first main surface provided thereon with a first device terminal and a second main surface provided thereon with a second device terminal, the electronic device test method comprising: (a) positioning a first socket and the electronic device under test; (b) causing the first socket and the electronic device under test to contact each other; (c) positioning the electronic device under test with respect to a second socket in a status where the first socket and the electronic device under test are contacted with each other; (d) causing the electronic device under test to contact the second socket; and (e) testing the electronic device under test in a status where the electronic device under test is caused to intervene between the first socket and the second socket; wherein (a) positioning the first socket and the electronic device under test includes: (f) imaging the first main surface of the electronic device under test; (g) recognizing, based on a first image information imaged by (f) imaging the first main surface of the electronic device under test, a first relative position of the electronic device under test with respect to the first socket; and (h) correcting a position of the first socket or the electronic device under test based on the first relative position, and (c) positioning the electronic device under test with respect to the second socket includes: (i) imaging the second main surface of the electronic device under test; (j) recognizing, based on a second image information imaged by (i) imaging the second main surface of the electronic device under test, a second relative position of the electronic device under test with respect to the second socket; and (k) correcting a position of the electronic device under test based on the second relative position; wherein (a) positioning the first socket and the electronic device under test further includes (l) imaging the first socket, (g) recognizing the first relative position of the electronic device under test with respect to the first socket includes: (m) extracting a position of a first socket terminal from a third image information imaged by (l) imaging the first socket, the first socket terminal being electrically connected with the first device terminal within the first socket; (n) extracting a position of the first device terminal from the first image information; and (o) comparing the position of the first socket terminal and the position of the first device terminal to calculate the first relative position, (c) positioning the electronic device under test with respect to the second socket further includes (p) imaging the second socket, and (j) recognizing the second relative position of the electronic device under test with respect to the second socket includes: (q) extracting a position of a second socket terminal from a fourth image information imaged by (p) imaging the second socket, the second socket terminal being electrically connected with the second device terminal within the second socket; (r) extracting a position of the second device terminal from the second image information; and (s) comparing the position of the second socket terminal and the position of the second device terminal to calculate the second relative position.
