Flying probe testing device and rapid positioning device thereof

Abstract

The invention discloses a flying probe testing device and a rapid positioning device thereof. The flying probe testing device comprises a flying probe testing machine body opposite to a to-be-tested circuit board, wherein the flying probe testing machine body is used for bearing the flying probe rapid positioning device, one end of the flying probe testing machine body facing the to-be-tested circuit board is fixedly connected with a bottom plate, and a plurality of element pins needing to be tested are arranged on the circuit board to be tested; a slidable test circuit board which is arranged on the upper surface of the bottom plate, wherein a plurality of test pins used for testing the element pins are mounted at one end, facing the circuit board to be tested, of the test circuit board; and a sliding mechanism which is arranged between the bottom plate and the test circuit board. The device is simple in structure, and has a better error-tolerant rate, so that circuit boards with different designs can be well detected. The error range of the flying probe testing machine can be automatically detected in the pin detection process, so that the data can be provided for device maintenance.

Description

technical field [0001] The invention belongs to the technical field of printed circuit board testing, in particular to a flying probe testing device and a rapid positioning device thereof. Background technique [0002] The flying probe testing machine is used to test the circuit board, which is divided into two categories, one is to test the PCB, and the other is to test the PCBA. 1. An instrument for testing PCB boards (printed circuit boards) with small measuring point distances. It mainly tests the insulation and conduction values ​​of circuit boards. Perform real-time monitoring. [0003] The size of the circuit board is small, and the pins to be tested on the circuit board are even smaller, and the positions of each row of pins are different. When testing, because the distance between each pin is very close, when the test device moves a There is a deviation in the unit time. After multiple pins are tested, the error will become larger and larger, which will directly l...

Problems solved by technology

[0003] The size of the circuit board is small, and the pins to be tested on the circuit board are even smaller, and the positions of each row of pins are different. When testing, because the distance between each pin is very close, when the test device moves a There is a deviation in the unit. After multiple pins are tested, the error will become larger and larger, which will directly lead to the wrong test position, repeated testing or missing problems. Therefore, we need a flying probe test device with a corrective effect and Quick positioning device
