Problems solved by technology

In addition, the traditional method of pressing the reinforcing plate is to laminate a release film on both sides of a single or multiple prepreg stacks to form a sandwich structure. This sandwich structure is isolated by a mirror steel plate and then put into a hot press for hot pressing and curing. , After the curing is completed, the release film is torn off to obtain the finished product, and the disadvantage of this method is that two release films are required for each reinforcement board produced, and the release film cannot be used after being torn off.
Generally speaking, the production cost of the traditional reinforcing plate production method is large

Embodiment 1

[0026] A production method for improving the roughness of one side of a reinforcing plate, see figure 2 First, laminate the prepreg 11 with the inner release film 121 and the outer release film 122 in the form of: outer release film 122 / prepreg 11 / inner release film 121 / prepreg 11 / outer release film 122 It is made into a sandwich unit structure 1; wherein, the prepreg 11 can be a single prepreg, and the inner release film 121 is a PET release film or a PA release film, which can be selected according to the roughness requirements of the final FPC board for the reinforcing board Different release films with a thickness of 100μm and a surface roughness of 1.2μm.

[0027] Then, the sandwich unit structure 1 and the mirror steel plate 2 are stacked in the order of: mirror steel plate 2 / sandwich structure unit 1 / mirror steel plate 2 / … / mirror steel plate 2, to obtain a plate assembly;

[0028] Next, put the stacked plate assembly into a hot press for hot pressing and curing moldin...

Embodiment 2

[0031] First, laminate the prepreg, the inner release film, and the outer release film in the order of: outer release film / prepreg / inner release film / prepreg / outer release film to form a sandwich unit structure; among them, The prepreg is formed by stacking multiple prepregs; then the sandwich unit structure and the mirror steel plate are stacked in the order of: mirror steel plate / sandwich structure unit / mirror steel plate / sandwich structure unit / mirror steel plate to obtain a plate assembly; then the stacked The placed plate assembly is put into a hot press machine for hot-press curing. After hot-press curing and molding, the mirror steel plate is removed to obtain multiple sandwich unit structures, and each sandwich unit structure is separated and the inner release film and outer layer are torn off. Release film, that is, get two reinforcement boards.

Embodiment 3

[0033] Same as Example 1, the difference is that a PET release film with a thickness of 150 μm and a surface roughness of 0.3 μm is selected as the inner release film, and the reinforcing plate is produced according to Implementation 1, and a single-side roughness of 10 μm can be obtained. reinforcement board;

Abstract

The invention relates to the technical field of preparation of copper-clad plates, and particularly relates to a production method for improving roughness of one surface of a reinforcement plate. A sandwich unit structure is prepared by adopting a mode of sequentially matching a release film / a prepreg / a release film / a prepreg / a release film through overlapping in a hot pressing procedure, then isolated by using a mirror surface steel plate and then subjected to hot-pressing curing; and the release films in each sandwich unit structure are removed after the hot pressing curing is completed so that the two reinforcement plates can be obtained. According to the production method, the reinforcement plate with roughness on one surface can be prepared, the cost of raw materials is saved, the procedures are saved, and the production efficiency is increased.

Description

technical field [0001] The invention relates to the technical field of copper-clad laminates, in particular to a production method for improving the roughness of one side of a reinforcing board. Background technique [0002] Reinforcing board is one of the main materials in FPC board production. In the hot-press curing process of the reinforcement board, release films are laminated on both sides of a single or multiple prepreg stacks to form a sandwich unit structure. This sandwich unit structure is isolated by a mirror steel plate and then placed in a hot-pressed machine for hot-press curing molding, after the curing is completed, remove the single sandwich unit structure and tear off the release film to obtain the finished product. [0003] At present, in the lamination process of the reinforcing plate production process, the stacking method is as follows: figure 1 As shown, that is, a buffer layer is set on the lower heat plate in the same opening of the press, and then...
