Problems solved by technology

[0004] The production specifications of integrated circuit samples are different. When the extraction equipment is used to randomly extract many samples placed idle, the suction port has adsorption force on the samples to clamp them up. Due to the different specifications of the sheet samples, the adsorption force The suction force is different, which will cause the sample to swing under the force and then enter the extraction device, and there will be a corner phenomenon inside it, and some samples with small weight are easy to be adsorbed in large quantities, resulting in too much random extraction, which affects random sampling test efficiency work

Abstract

The invention discloses sample random extraction equipment for integrated circuit test. The structure is provided with a supporting column, a sliding frame, a moving device, a sliding block and a main motor, wherein the sliding frame is fixedly embedded above the supporting column, the moving device is fixedly connected to the sliding block, and the moving device is transversely placed when a movable body is subjected to adsorption force; an opening blocking state is formed at the position above the inner side of the suction opening by a certain distance, the oppositely-arranged air cushions make contact with each other and abut against each other, the air cushions are flexibly changed under cooperation of the air cushions and the fold pieces, transverse placement of the solid plate is not hindered due to too large friction of the front end of the solid plate, a vertical through diameter structure is formed between every two hoses, air flow circulation is facilitated, an adsorption effect is formed below the movable body, integrated circuit samples can be sucked up, balanced suction force is applied to the samples, and therefore it is guaranteed that only one circuit board is sucked, uniform suction force is applied to the samples of different specifications and sizes, and the situation that when the suction force is different, the sheet-shaped samples tilt and are clamped into the suction device, and the extraction work efficiency is reduced is avoided.

Description

technical field [0001] The invention belongs to the technical field of integrated circuit testing, and more specifically relates to a sample random sampling device for integrated circuit testing. Background technique [0002] With the development of science and technology, integrated circuits, as miniature electronic devices, are ubiquitous in modern production and life. After the production of integrated circuits, acceptance testing is still required. Usually, random sampling and testing of many integrated circuit samples is performed using sample random sampling equipment. , to estimate the pass rate. [0003] Based on the inventor's discovery above, the existing sample random sampling equipment for integrated circuit testing has the following deficiencies: [0004] The production specifications of integrated circuit samples are different. When the extraction equipment is used to randomly extract many samples placed idle, the suction port has adsorption force on the sampl...
