Apparatus that probing de-capsulated chip

The present invention offers an apparatus that can probe and analyze a de-capsulated chip with probing needles of a probe chuck plate on a fully automatic probe machine. The apparatus is composed of a probe plate that has a first side which is placed on the probe chuck plate, and has a second side that has at least one hollow that the chip can be put in. And the probe plate has one hole passing through the hollow and the first side, in order to catch the chip by the suction of the probe chuck plate through the hole. Then the chip is probed with the probe needles.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now to FIG. 1 and 2 . The present invention refers to an apparatus. The apparatus is used to place a de-capsulated chip 13 . The apparatus is applied to testing by probe needles 21 of a probe chuck plate 20 on a fully automatic probe machine. The apparatus includes: a probe plate 10 that has the first side 10 a which is placed on the probe chuck plate 20 , and has the second side 10 b that has at least one hollow 12 that the chip 13 can be put in. And the probe plate 10 has one hole 14 pass through the hollow 12 and the first side 10 a, in order to catch the chip 13 by the suction of the probe chuck plate 20 through the hole 14 . Then the probe needles 21 probe the chip 13 . And the depth of the hollow that is on the second side of the probe plate is smaller than the thickness of the chip. Refer now to FIGS. 1 and 2 . This embodiment is the probe plate 10 with the chip 13 on the probe chuck plate 20 of the fully automatic probe machine, such as TSK maker's model UF- 2000 and TEL maker's model P 8 . Then the chip 13 is caught and fixed through the hole 14 by vacuum. Next, the fully automatic probe machine can by means of the alignment marks 11 in FIG. 1 to determine the position of the probe plate 10 and the chip 13 , in order to let the probe needles 21 to aim at the chip 13 exactly for probing. Here it must be emphasized is that the size of the hollow 12 of the probe plate 10 can be made in a different size, in order to match the chip 13 which is needed for probing. And the quantity of the hollow 12 of the probe plate 10 can be plural. So no matter how many chips 13 on the hollow of the probe plate 10 , all the chips can use the apparatus of this invention to be tested in the same fully automatic probe machine. That greatly ameliorates the inconvenient situation of the prior art. In accordance with the present invention, it greatly ameliorates the inconvenient situation of the prior art, and also improves the accuracy and reliability for analysis, improves efficiency, and saves a lot of cost. So the present invention has progress and practicability. Finally, while the invention has been described by way of example and in terms of the preferred embodiment, it is to be understood that the invention is not limited to the disclosed embodiments. On the contrary, it is intended to cover various modifications and similar arrangements as would be apparent to those skilled in the art. Therefore, the scope of the appended claims should be accorded the broadest interpretation so as to encompass all such modifications and similar arrangements.
