Abstract

The invention provides a detector for efficiently and automatically identifying faults of a flexible printed circuit board (FPCB). According to the invention, a high-precision marble platform is connected with a base through bolts, a table top of the marble platform is used for bearing an X-axis portal frame structure and two moving platforms in a Y-axis direction, the parts of two working platforms on the marble platform in the Y-axis direction are symmetrical and consistent and are free of mutual interference during working, and high-precision grating bars are respectively arranged on the moving platforms in the X-axis direction and the Y-axis direction so as to ensure that the closed-loop high-precision position motion control of the three platforms is realized, thus, the purpose of efficiently and automatically identifying the faults of the FPCB is achieved. The detector provided by the invention has the beneficial effect of being capable of detecting the faults of the FPCB stably and accurately at a high speed.

Description

technical field [0001] The invention relates to a device for detecting defects on the surface of a circuit board, in particular to a detection machine capable of automatic identification of defects in flexible printed circuits with high precision and high efficiency. Background technique [0002] With the continuous improvement of the level of industrial processing and manufacturing, and the development trend of electronic products in my country, the demand for FPCB (flexible printed circuit) is increasing year by year, and due to the characteristics of the FPCB manufacturing process, due to equipment conditions, Changes in environmental conditions, personnel quality, process design, process parameter control and other factors can easily lead to defects. Its detection process is the key in the technological process. Due to the design of flexible printed circuit boards, there are high-density, ultra-fine traces and ultra-fine-pitch component pads, and the relatively complex m...
