Description of the invention: [Technical field to which the invention pertains] The present month is a face-to-needle structure, and in particular, the face-f-type probe card structure can have elasticity that can be longitudinally retracted in addition to having a scale-like position. , maintain good contact with external components during the test. , L flawless technology] Before the wafer in the semiconductor industry has not been packaged, in order to avoid packaging into the bad crystal 2 auxiliary _ coffee _ order, the object crystal to do the electrical test work of the probe item, and then screen out the wafer The quality is good and repaired or scrapped' while the good products are re-engineered to reduce the waste of packaging resources. ^ Thus, the probe card _ the majority of the probe as a time-to-electric contact between the domain material (such as the wafer), in order to make it firmly attached to the object to be tested (such as the tin on the wafer = up = = 峨 she _ Wheel) ±, # probe ^ Test the wafer at a predetermined distance from the eye distance corresponding to the contact, tm to eliminate unnecessary electrical interference. Item material miscellaneous needles - needle (four) (four) to test the early foot type of needle to insert the assembly method combination, 疋丄, so that the needle can not be made in the position of the towel, so the group after the completion of 201245727 by epoxy resin (Epoxy Fixing 'can maintain the deflection of the probe in the y-axis and Y-axis direction' but the tip of the probe cannot control the deflection in the z-axis direction, nor can it be accurately positioned and contacted with the object to be tested (such as a wafer) The correct position can cause damage to the wafer, or problems such as insufficient accuracy and increased defect rate. SUMMARY OF THE INVENTION In view of the problems arising from the above-described prior art, the inventors have considered designing a modified cantilever probe card structure to solve this problem. An object of the present invention is to provide a cantilever type probe card structure, which is a U11 conductive element for guiding a probe of a contact electrical mechanism, and the probe can stabilize the connection between the axis Ic component and the circuit board. Conductive element. Another object of the present invention is a warp-type cantilever probe card structure in which the cantilever probe has a positioning member capable of pinching _ precision to stabilize the probe in position. For the purpose of the present invention, the present invention provides a splicing probe card structure comprising at least a probe having a probe body, a tip attached to the body of the probe, and Connected to the other end of the probe (4), i, the plate has at least one, the correcting end - is fixed by a glue on an insulating mechanism (such as a probe fixing seat or a fixing plate), the plate The other end of the piece is connected with the positioning piece and the news material, and the towel, the joy and the material can be at least 201245727, and the signal conducting part is used for external contact by surface contact (such as surface following technology or welding). The member is electrically contacted. The positioning and signal transmission are used to achieve accurate positioning and stable signal transmission. The present invention provides a cantilever type probe card structure, which has the following advantages: (1) the probe card of the present invention, the correcting of the shot, the enemy, and the fixed position function of the positioning member. The result of the comprehensive effect makes the probe more precise on the object, which can eliminate the object to be tested (such as the damage of the object to be tested due to the error of the sticking point.) (2) The positioning part can stabilize the position of the probe to increase the test. The frequency makes the probe card not need to be disassembled frequently to reduce the needle position, reduce the number of secrets, save the cost of the dimension: and then increase the rate of continuous testing of the machine. Here, in order to make the material surface (four) in the paste - According to this book (10), the method of financial management is based on the following: Therefore, it is better to use the preferred embodiment, with the pattern, the same component, and the fourth component.
