Abstract

PURPOSE:To obtain a laminated board capable of prevention of change in properties of prepregs by overlaying a predetermined sheet of main prepregs being transported continuously to 1-2 sheets of sub-prepregs, furthermore, heat compression-molding a laminate being disposed with metallic foil on the uppermost surface and/or the lowermost surface thereof. CONSTITUTION:A sheet of prepreg is transported from the site 1 for phenol resin prepreg to the assembly site 3 by a sliding way 2, next, seven (7) sheets of phenol resin prepreg 6 coming by transportation from a dryer 4 continuously by being cut by means of a cutter 5 are put thereon at a belt conveyor 7, furthermore, the laminate mounted by a catching method 9 with a sheet of copper foil from a site 8 of copper with adhesive agent is heat compression- molded on the uppermost surface thereof in order to obtain a one-surface copper plated laminated board. As a result, a laminated board can be obtained, which is capable of improving the efficiency, reducing the prepreg preservation space, and preventing change in properties of the prepregs.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a method for manufacturing a laminate used for electronic equipment, electrical equipment, computers, communication equipment, etc.

[Conventional technology]

Conventionally, laminates have been made using phenol resins, epoxy resins, melamine resins, polyimide resins, non-11al, ilj polyester resins, polyphenylene oxides, fluororesins, bo-11-butadiene, etc. on woven fabrics, non-woven fabrics, paper, etc. such as paper, synthetic fibers, and glass fibers. One set consists of a laminate consisting of the required number of prepregs impregnated with synthetic nitric resin and dried, with metal foil such as copper foil arranged on the upper and/or lower surfaces as necessary, and 2
The laminate 8 to 1 is placed between each stage of a multi-stage press of about 0 to 35 stages.
Although it is obtained by storing 5 sets of prepregs and molding them under heat and pressure, the 11 pregs are not all composed of the same type of prepreg, but are composed of several sets of prepregs. For example, a prepreg with improved copper foil adhesion, a prepreg with a manufacturer's mark, etc. are used in combination with the main prepreg, but this combination is all done manually.

[Problem that the invention seeks to solve]

As mentioned in the conventional technology section, it is complicated to manually combine and create a large number of prepregs, and the work efficiency is low. Storage space and changes in prepreg quality during storage were problems. The present invention has been made in view of the above-mentioned problems in the conventional technology, and its objectives are to simplify the process of assembling the P11 preg, to increase the size of the moving vehicle and to reduce the storage space of the P11 preg, and to change the quality of the Buri preg. It is an object of the present invention to provide a method for manufacturing a ram no board that can prevent such damage.

[Means for solving problems]

The present invention is an M carcass in which a required number of main prepregs continuously transferred from a dryer are layered on top of one or two subprepregs, and metal foil is further arranged on the top and/or bottom surfaces of the main prepregs. The manufacturing method of laminates is characterized by heat-pressure molding, which simplifies and improves the efficiency of the joining process, and saves space by eliminating the need for storage space for the overwhelmingly large number of main prepregs. The present invention will be explained below based on the illustrated embodiments.

Embodiment FIG. 1 is a simplified process diagram of a method for manufacturing a laminate according to an embodiment of the present invention.

0.21 m thick, 1050 x 1050 phenol resin resin with manufacturer's mark 11 From the preg storage area 1, one sheet of the phenolic resin preg is sent to the assembly area 3 on the sliding table 2. Seven sheets of phenolic resin prepreg 6 with a thickness of 0.2 vrx, which are continuously cut into 1050 x 1050 fl with a force-cutting machine 5, are piled up on a belt conveyor 7, and a layer with a thickness of 0.0 fl is placed on the top surface. .03511M, 1050X 1050
1000 pieces of copper foil from ta field 8 of copper foil with shielding agent of ff.
The laminate placed by soaking method 9 was molded under a molding pressure of 100 K.
Q/d, heated and pressure molded at 160°C for 60 minutes to a thickness of 1.
I got a 6-inch single-sided copper-clad laminate board.

〔Effect of the invention〕

The present invention is constructed and operated as described above. The method of combining prepregs having the structure described in claim 1 has the effect of simplifying the process, increasing efficiency, reducing the space of the prepreg and tube, and preventing deterioration of the prepreg. be.
