Problems solved by technology

[0003] Random extraction, that is, according to the principle of randomness, some units are selected from the overall unit as samples. After the integrated circuit packaging is completed, an acceptance test is required. The acceptance test generally uses a random sampling test method to estimate the pass rate. At this time It is necessary to randomly extract product samples. The current sample random extraction device generally uses the cylinder to drive the chuck to clamp the sample. However, due to the high precision of the sample, the distance pushed by the cylinder is not easy to control, and it is easy to cause damage to the sample. The existing sample random extraction device is not easy to accurately adjust the height of the chuck, and it is not easy to quickly adjust the clamping position of the chuck, resulting in inconvenient clamping and placement

Abstract

The invention discloses a sample random extraction device for integrated circuit testing. The device comprises an accurate adjusting mechanism and a rotary adjusting mechanism. The adjusting mechanismis arranged at the bottom of the fourth air cylinder; a hand wheel is rotated to enable a first screw rod to drive a third sliding block and a top supporting plate to move towards the upper end through a moving plate so that the top supporting plate drives a second supporting plate to change the height, a pointer can indicate on an indicating plate to accurately know the adjusted height, and theadvantage that the height of a chuck can be accurately adjusted is achieved; the rotary adjusting mechanism is arranged at the bottom of the accurate adjusting mechanism; the fifth air cylinder drivesa rack to move through a push block, the rack drives a first belt wheel to rotate through a gear, and thus the first belt wheel drives a second belt wheel to rotate through a belt, the second belt wheel drives the position of a clamp to be changed through a rotating block, and the advantage that the clamping position of a chuck can be rapidly adjusted is achieved.

Description

technical field [0001] The invention relates to the related field of integrated circuit testing, in particular to a sample random sampling device for integrated circuit testing. Background technique [0002] An integrated circuit is a microelectronic device or component that uses a certain process to interconnect components such as transistors, resistors, capacitors, and inductors required in a circuit, and interconnects them together to form a small or several small semiconductor chips or chips. Dielectric substrate, and then packaged in a package, to become a microstructure with the required circuit functions; all the components have been integrated in the structure, making electronic components towards miniaturization, low power consumption, intelligence and high reliability. A big step forward in terms of sex. [0003] Random extraction, that is, according to the principle of randomness, some units are selected from the overall unit as samples. After the integrated circ...
