New Description: [New Technology Field] This creation is to provide a probe card modification for the wafer electrical tester, which is mainly applied to the technology of the probe card of the wafer electrical tester. . [Prior Art] According to the probe card of the conventional wafer electrical tester, refer to the structure diagram of the conventional formula. The structure is mainly composed of a combination of a probe card fixing jig 1, a printed circuit board 2, a probe card 3 for a micro-product process, and a cantilever probe 4 for a micro-product process. However, the probe card of the above-mentioned conventional wafer electrical tester still has at least the problems and defects that need to be solved in the practical application: ~ First, because the probe is made up of micro-products Made by the process (MEMS) method, the material is Shi Xi, the essence of Shi Xi is hard and brittle. As long as the operation is improper or accidental collision, the probe may be broken and the probe durability is not good. 2. The probe itself is fixed on a glass substrate. The fixing method is to fix the probe by means of metal on the ore (Cu copper). The equipment used is only available in the original factory, such as the probe. In case of damage, it is not easy to repair', that is, the entire set of probes must be returned to the original factory for repair, which is time-consuming and labor-intensive. Third, because the printed circuit board and the probe card are designed to be integrated, they cannot be separated. As long as the product specifications change, that is, their position _ position changes, the probe position on the probe card is changed, and the needle card is complete. It is necessary to re-create a new one, and it is necessary to replace the entire set of probe cards, which is costly. [New Content] 4 M358301 In view of the fact that this creative personality is actively investing in research and development and innovation, the final creation of this book is to provide a probe card structure improvement for the wafer electrical tester. New problem-solving - the technical means applied and the effect of the prior art are based on the fact that the 矽 probe is changed to a metal probe, and the metal itself has better strength, so it is not easily damaged and has good durability. The new technical means to solve the problem 2 and the efficacy of the prior art are: even if the probe is deformed due to improper use, it can still be called to manually adjust the probe to 'return the original function, easy to maintain, save Time labor. The technical means of applying the new problem solving three and the efficacy of the prior art are based on: designing the printed circuit board and the probe card into two separate circuit boards, and utilizing between the printed circuit board and the probe card. The soft intermediate conduction interface is used for the connection, so as long as the test point position of the product to be tested is changed, 'the probe card only needs to be replaced, the printed circuit board and the intermediate conduction interface do not need to be replaced, and the cost is low. • [Embodiment] In order to make it easier for those who are familiar with the technology to understand the construction content of the creation and the functional benefits that can be achieved, a specific embodiment will be listed, and the detailed description will be given as follows: The structure of the probe card of the wafer electrical tester is improved, please refer to the second figure: a schematic diagram of the three-dimensional combination of the first embodiment of the present invention. And the third figure shows a schematic diagram of the sectional combination of the first embodiment of the present invention. And the fourth figure shows a schematic diagram of the state of use of the first embodiment of the present invention. The structure of the M358301 is designed in such a way that the inter-radiation interface 1 Q is combined with the printed circuit board 2 ,, and then the screw-on interface 1Q and the probe card fixing fixture 40 are locked by the screw 30 to make the towel (4) interface 1 〇 can completely close the drunk printed circuit board 20, and achieve the flatness required for the intermediate conduction interface 1〇. Then, using the flatness of the intermediate conductive interface 10 as a reference surface, the probe card 5 〇 is fixed under the intermediate conductive interface 1 ,, and the fixing screw and the spring cymbal 70 are adjusted to adjust and adjust the flatness. The intermediate conductive interface 丄〇 upper and lower corresponding to the printed circuit board 20 and the probe card 5 〇 metal pad 2 丄, 5 work ♦ is provided with a conductive interface pin 丄i made of metal powder, as a printed circuit board 20 and the probe card 50 are electrically conductive, and the probe 5 2 of the probe card is made of a metal material.
