Attaching method of steel sheet enhancing sheets of flexible circuit board, jigs of flexible circuit board, and strip attaching steel sheets of flexible circuit board

Abstract

The invention discloses an attaching method of steel sheet enhancing sheets of a flexible circuit board, jigs of the flexible circuit board, and strip attaching steel sheets of the flexible circuit board. The method includes the first step of arranging pure glue, covering enhancing sheet attaching positions located on the upper portion inside all regions surrounded by all grooves, on all rows of grooves of the flexible circuit board, the second step of enabling position fixing stop dogs corresponding to the jigs to be sleeved with all the rows of grooves of the flexible circuit board, and enabling upper positioning pins to be sleeved with first positioning holes above all the rows of grooves, the third step of attaching the steel sheet enhancing sheets of the strip attaching steel sheets corresponding to all the rows of grooves to the pure glue in the enhancing sheet attaching positions, and enabling each positioning pin to be sleeved with the corresponding strip attaching steel sheet through a second positioning hole of a connecting rib, the fourth step of placing the jigs into a false attaching machine along with the flexible circuit board and the strip attaching steel sheets to be pressed in advance, pressing the pure glue through a hot press after pressing is conducted through the false attaching machine in advance, and enabling all the steel sheet enhancing sheets to be attached to the enhancing sheet attaching positions of the flexible circuit board, and the fifth step of stripping all the connecting ribs of the strip attaching steel sheets from the steel sheet enhancing sheets on the connecting ribs. According to the method, the multiple enhancing sheets can be simultaneously attached, the attaching efficiency is improved, and the operation is convenient.

Description

technical field [0001] The invention belongs to the field of flexible circuit boards, and in particular relates to a lamination method of steel sheet reinforcing sheets of flexible circuit boards, a jig used in the method and strip-attached steel sheets. Background technique [0002] The biggest advantage of flexible circuit boards is that they are flexible, can be bent, wound, and folded freely, can be arranged arbitrarily according to the requirements of space layout, and can be moved and stretched arbitrarily in three-dimensional space, so as to achieve the integration of component assembly and wire connection; but However, it is a big deficiency in the bearing capacity of components, so it is necessary to attach reinforcement sheets to flexible circuit boards with soldered components, and steel sheet reinforcement sheets are one of the most common reinforcement sheets. [0003] The manufacturing process of flexible circuit boards generally includes: dry film lamination, ...

AI Technical Summary

Problems solved by technology

[0003] The manufacturing process of flexible circuit boards generally includes: dry film lamination, exposure, imaging, etching and stripping, and reinforcement sheet bonding processes. In the existing process of using fixtures to attach reinforcement sheets, the steel sheet reinforcement sheet is a single loose sheet , and then attached to the flexible circuit board through the corresponding fixture, this method has the following disadvantages: the position of the steel sheet reinforcement is determined and placed one by one manually, and the production efficiency is low, especially when the shape of the steel sheet reinforcement is asymmetric , when laminating, it is necessary to further select the appropriate laminating direction to further reduce the efficiency
