Rotary type flexible circuit board testing jig

Abstract

The invention provides a rotary flexible circuit board testing clamp, comprising a rotating bracket, an interface switching device, a platform testing interface and a testing probe pen. The rotation bracket comprises a column, a rotating shaft and a clamping device. The rotating bracket is arranged on a testing platform; the two ends of the circuit board to be tested are clamped by the clamping device and fixed on the rotating bracket; the testing interface of the circuit board to be tested is connected with the platform testing interface by the interface switching device. In the testing process, according to the requirement, the circuit board to be tested is rotated so as to lead the circuit board to be arranged at any angle; the testing personnel can measure the signals of testing points on any one surface of the frontal surface and the back surface of the circuit board to be tested by using the testing probe pen, thus leading the testing process to be continuous and quick. The clamp of the invention has the advantages of simple structure, low cost and convenient adjustment, and is suitable for testing the circuit board of variable specifications.

Description

technical field [0001] The rotary flexible circuit board test fixture of the invention belongs to the technical field of electronic equipment detection and maintenance, and provides means for circuit board automatic test and fault diagnosis. Background technique [0002] At present, in the testing of circuit boards in electronic equipment, in addition to automatic testing through the test interface of the circuit board, it is often necessary to use test probes or probes to attach test points on the circuit board during the test process. test. Usually, the tested circuit board is a double-sided board, and the test points are distributed on the front and back sides of the tested circuit board. The measured points on either side of the front and back of the circuit board need to re-fix the circuit board, which will cause the test process to be interrupted and affect the test. At the same time, it also makes the interface switching device complicated and difficult to use unive...

AI Technical Summary

Problems solved by technology

Usually, the circuit board under test is a double-sided board, and the test points are distributed on the front and back sides of the circuit board under test. The measured points on either side of the front and back of the circuit board need to be fixed again, which will cause the test process to be interrupted and affect the test

At the same time, it also makes the interface adapter device complex and difficult to use universally

[0003] In order to solve the above problems, the common solution is to use the bed of needles test, and the bed of needles test is characterized by complex structure, high price, and restrictions on the specifications of the tested circuit board.
