A total of 16 electronic components 20 are completed in a total of 5 tests.
- the two wafers 701 and 702 are delivered to an unloader section (not shown), and the first prober group 603 is delivered. 1.
- the next wafers 701 and 702 are supplied from the second propeller group 602 or from an independent loader unit for each propper group. Note that the test timing of the first prober group 601 and the second prober group 602 and the test timing of the third prober group 603 and the fourth prober group 604 are determined by the main controller MC (not shown). ) Synchronizes each mobile device, and tests are performed at the same timing.
- the first propeller for testing the electronic component 20 located at the center of the wafers 701 and 702 Simultaneous measurement by dividing into the group 611, the second prober group 602, the third prober group 603 for testing the electronic components 20 near the outer periphery, and the fourth prober group 604 It is possible to secure test locations close to the constant 64, especially the electrons to be tested on wafers 701 and 702 near the outer periphery where it is not always possible to secure test locations for the number of simultaneous measurements. High test efficiency is achieved in the testing of component 20.
- the method of gripping the wafer with the gripping head and moving the movable head having the gripping head is adopted.
- the method is not limited to this method.
- a method of controlling the position of the group of components with respect to the electronic component is also conceivable.
- the present invention is not limited to the test order of the electronic component under test on the electronic component carrier medium described in the third embodiment, and the efficient test order of the electronic component under test on the electronic component carrier medium can be changed.
- the purpose is to include.
- the number of simultaneous measurements in the embodiment of the present invention is not limited to the above number, but can be applied to 2n simultaneous measurements.
