FPC identification and detection method and FPC identification and detection device

Abstract

The invention discloses an FPC (Flexible Printed Circuit) identification and detection method and an FPC identification and detection device. The FPC identification and detection method comprises the following steps: transferring a to-be-detected FPC subjected to circuit etching to the surface of a fluorescent platform; a nano fluorescent probe in the fluorescent platform vertically and upwards emits light to the FPC to be detected; the spectral grating scans the FPC to be detected and the fluorescent platform to obtain a group of spectral pattern structures; performing contrast combination and cutting processing on the spectral pattern structure; and performing year-on-year measurement on the cut spectral pattern structure, comparing the obtained data with manufacturing data of the FPC to be detected, and judging whether the FPC to be detected belongs to a qualified product or not. Compared with the prior art, the FPC identification and detection method and the FPC identification and detection device have the advantages that the visual identification function is achieved, the detection efficiency is improved, the detection accuracy is ensured, and the actual service life of a detected product is prolonged.

Description

technical field [0001] The invention relates to the technical field of FPC production, in particular to an FPC identification and detection method and an FPC identification and detection device. Background technique [0002] FPC, also known as flexible circuit, is a technology developed by the United States for the development of aerospace rocket technology in the 1970s. It is made of polyester film or polyimide as a base material with high reliability and excellent performance. Flexible printed circuit, by embedding a circuit design on a flexible thin plastic sheet, so that a large number of precision components can be embedded in a narrow and limited space to form a flexible flexible circuit, which can be bent and folded at will. The stacking weight is light, the volume is small, the heat dissipation is good, and the installation is convenient. It breaks through the traditional interconnection technology. In the structure of the flexible circuit, the materials are composed...
