Problems solved by technology

[0003] The probe card is fastened by multiple screws. As the market demand increases, the production of the probe card will also increase. The traditional processing process is fastened by the staff holding the batch rod, which will greatly reduce the probe cost. The working efficiency of needle card production requires a screw fastening device for probe cards, but there are many problems or defects in the existing screw fastening devices for probe cards: first: the existing probe card production process Most of the fastening methods are manually aligned by the staff to the thread on the probe card and then screwed in, which not only increases the workload of the staff, but also greatly reduces the cost of the probe card. Second: There are multiple motors in the screw fastening device for probe cards, and the motors will generate a lot of heat during use. If the heat is not discharged in time, it may lead to the shutdown of the screw fastening device for probe cards , affecting work progress

preparation example Construction

[0063] In some preferred embodiments, the preparation method of the rubber layer of the metal-rubber composite sealing plate includes the following steps:

[0064] (1) Add N,N-nickel di-n-butyl dithiocarbamate, calcium oxide, white carbon black, calcined kaolin, silane coupling agent, zinc stearate, petroleum wax, ethyl acetate into the mixer, and Mix at 80-90°C to obtain a mixed slurry;

[0065] (2) adding nitrile rubber and carbon fiber into the internal mixer for internal mixing for 40-60 minutes, then raising the temperature to 100-120°C for debinding to obtain mixed colloids;

[0066] (3) Add sulfur to step (2), knead on a two-roller mill, add sulfur, mix well, then add twin-screw extruder for granulation, put the obtained rubber masterbatch into a vulcanizer for vulcanization For molding, the vulcanization pressure is set at 12-14MPa, the vulcanization temperature is set at 120-135°C, and the vulcanization time is set at 60-80 minutes.

[0067] In some preferred embodi...

Embodiment 1

[0080] see Figure 1-4 , an embodiment provided by the present invention: a screw fastening device for probe cards, including a support cabinet 1, a work surface 2, a support rod 3, a cross bar 4 and a hydraulic telescopic rod 5, and the inside of the support cabinet 1 A storage room 101 and an installation room 102 are provided. Through the storage room 101, the parts related to the operation can be stored, which is convenient for the staff to take during the operation, expands the space use range of the device, and supports the movable installation of the front of the cabinet 1. There is a movable protective door, and the movable protective door is equipped with a cooperating observation window;

[0081]The inside of the installation chamber 102 is placed with a first motor 103, the output end of the first motor 103 is rotatably connected with a transverse gear 105 through a longitudinal gear 104, and a rotating shaft 106 extending into the worktable 2 is installed through t...

Embodiment 2

[0086] A screw fastening device for probe cards, the structure of which is the same as that of Embodiment 1. The difference from Embodiment 1 is that the front sealing plates of the second motor housing 301 and the third motor housing 501 are made of metal-rubber composite sealing plates.

[0087] A raw material for preparing a rubber layer material for a metal-rubber composite sealing plate, comprising: 90 parts of nitrile rubber, 0.5 parts of N,N-nickel di-n-butyldithiocarbamate, 2 parts of calcium oxide, and gas phase 0.9 parts of French silica, 0.18 parts of calcined kaolin, 1.4 parts of γ-methacryloxypropyl trimethoxysilane, 3.2 parts of carbon fiber, 0.2 parts of zinc stearate, 2 parts of petroleum wax, 2.5 parts of sulfur, acetic acid 150 parts of ethyl ester.

[0088] The weight ratio of fumed white carbon black to calcined kaolin is 1:0.2.

[0089] The mesh number of the calcined kaolin is 1250 mesh.

[0090] The weight ratio of carbon fibers with an average length ...

Abstract

The invention discloses a screw fastening device for a probe card, which comprises a support cabinet, a working table, a support bar, a cross bar and a hydraulic telescopic bar. A first motor is placed inside the installation room, and the first motor The output end of the vertical gear is rotatably connected with the horizontal gear, and the horizontal gear is installed with a rotating shaft extending into the worktable, and the top of one side of the support rod is fixedly installed with a second motor through the second motor casing. A screw rod is fixedly installed inside the cross bar, and a hydraulic telescopic rod is slidably installed on the screw rod through a sliding block, and a third motor is fixedly installed on the bottom of the hydraulic telescopic rod through a third motor casing. The output end of the motor is fixedly installed with a batch rod through the batch rod installation seat. By improving the sealing plate arranged on the motor casing, the prepared sealing plate has better heat dissipation performance, improves work efficiency, and reduces the occurrence of danger in equipment operation.

Description

technical field [0001] The invention belongs to the technical field of probe card production, and more specifically relates to a screw fastening device for a probe card. Background technique [0002] The probe card is a kind of testing element for testing semiconductor components whether there is no defect at the wafer level. The testing method includes: electrically connecting the wafer and the semiconductor component testing equipment, and transmitting the electrical signal of the testing equipment to the formed on the wafer. The pad, and the signal returned from the pad is passed to the inspection equipment of the semiconductor element. [0003] The probe card is fastened by multiple screws. As the market demand increases, the production of the probe card will also increase. The traditional processing process is fastened by the staff holding the batch rod, which will greatly reduce the probe cost. The working efficiency of needle card production requires a screw fastenin...
