AI Technical Summary

Technical Problem

In the prior art, the detection of the flatness of the press opening of the fast press mainly depends on visual methods, and it is difficult to quantitatively evaluate the flatness of the press, resulting in bubbles, voids, layering and other problems between the auxiliary materials and the soft circuit board, affecting the appearance and function of the circuit board.

Method used

A flatness detection circuit board for soft-wire circuit board pressing equipment is designed, including a base layer, a coloring layer and an isolation layer. The flatness is judged by the adsorption and distribution of the colorant after pressing in the pressing opening of the fast press. The flatness is judged by the machine or artificial number of grids with coloring agents attached to the total number of grids, and the proportion of coloring area accounts for ≥85%.

Benefits of technology

Quantitative detection of the flatness of the pressing equipment is realized, and the flatness of the pressing opening of the fast press can be accurately judged, thereby improving the quality and stability of the circuit board and avoiding the problems of poor appearance and functionality.

Abstract

The utility model discloses a flatness detection circuit board for flexible circuit board pressing equipment, which comprises a substrate layer, a coloring layer and an isolating layer which are sequentially laminated from bottom to top, the flatness of the lower surface and the upper surface of the substrate layer is less than or equal to 5 microns, the flatness of the lower surface and the upper surface of the isolating layer is less than or equal to 5 microns, and the flatness of the upper surface and the lower surface of the isolating layer is less than or equal to 5 microns. The thickness of the coloring layer is smaller than or equal to 100 microns, the flatness of the lower surface and the upper surface of the coloring layer is smaller than or equal to 15 microns, and a coloring agent of the coloring layer is located on the lower surface; the upper surface of the base body layer is divided into a first grid array; after the base body layer, the coloring layer and the isolation layer are pressed in the pressing opening of the fast pressing machine, the coloring agent part of the coloring layer is adsorbed in part of or all the grids on the upper surface of the base body layer, the number of the grids with the coloring agent in all the grids is counted mechanically or manually, and the pressing opening of the fast pressing machine can be judged to be qualified if the proportion of the coloring area is larger than or equal to 85%. Therefore, the press-fit flatness of the press-fit equipment can be quantified.
