Problems solved by technology

However, it has the following defects: 1. It uses a CCD to capture the front lighting. This effect is only applicable to FPC boards that do not have reflective materials. If the material is reflective, it will affect the position accuracy of the CCD capture. This application provides a new The backside lighting structure can solve the above problems
3. Its mechanical product carrier is not suitable for fixing small, thin and high-precision FPC boards

Abstract

The invention provides a high-precision contact type auxiliary test jig and a work method thereof. The test jig comprises a mechanism outer frame unit, a test unit, a pressing unit and an imaging unit. The high-precision contact type test mechanism is reasonable in structure, and can be used for electrical testing, including resistance testing, capacitive testing, short-circuit testing, passage testing and the like, of circuit boards for various contact type tests. The detection precision is high, and the accuracy is good. The imaging unit adopts a structure mode of back lighting, the reflection problem caused by front light supplementing is avoided, the test precision is greatly improved, and the production efficiency is improved. The jig is reasonable in working method and easy to obtain, the direct contact alignment test is carried out, a probe contact test is not needed, testing is convenient, results are accurate and stable, and a detected product cannot be damaged.

Description

technical field [0001] The invention belongs to the field of DT testing fixtures, and in particular relates to a high-precision contact testing mechanism, especially but not limited to ICT testing of ultra-thin flexible circuit boards. Background technique [0002] Flexible circuit board is a kind of highly reliable and excellent flexible printed circuit board made of polyimide or polyester film as the base material. It has high wiring density, light weight, thin thickness, bending Sexual characteristics. [0003] In the process of producing flexible circuit boards, in order to ensure that the produced flexible circuit boards are qualified, each flexible circuit board needs to be tested, including open circuit, short circuit, capacitance, resistance, inductance and switch of flexible circuit board (FPC) products Wait for the original test. Now it is mainly used to test the flexible circuit board DT test fixture through manual feeding, manual adjustment, and adjust the micr...
