DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing a laminate. More specifically, the present invention relates to a method for producing a laminate by heat and pressure lamination, which is useful for producing printed wiring boards and the like, and can improve productivity, workability, and laminate performance. is there.

[0002]

2. Description of the Related Art Hitherto, laminated boards for printed wiring boards have been manufactured by lamination molding by heating and pressing. Usually, a required number of prepregs for laminated boards are placed between upper and lower heating and pressing press plates. Or a metal foil, an inner layer material for a multilayer printed wiring board, and the like are arranged together with a metal plate for heat transfer, and this is heated and pressed to form a laminate.

[0003] In many cases, a stripping prevention jig for preventing a required number of prepregs, resin sheets, or metal foils from being stripped (displaced) at the time of lamination molding is used in this lamination molding. . This jig includes a frame type and a cover type. In each case, as shown in FIG. 4, for example, as shown in FIG. And a tongue and foot piece (a) provided.

[0004]

However, in the case of this conventional stripping prevention jig used for lamination molding, the height (H) of the tongue foot piece (a) suspended from the flat plate part (a).
Is constant, it is absolutely necessary to make the number of moldings per stage in the lamination molding by this jig constant, or to arrange and arrange the dummy boards as necessary and adjust the height. there were.

[0005] For this reason, in the production of a conventional laminated plate, the height (H) of the tongue and foot piece (a) is changed in order to form various thicknesses or to change the number of laminated layers. It was necessary to prepare several sets of separate jigs and prepare them. Therefore, the cost for this and the replacement and preparation of these jigs require labor and time, which is a factor that inevitably limits the improvement in productivity and workability.

The present invention has been made in view of the above circumstances, and solves the drawbacks of the conventional method of manufacturing a laminate using a stripping prevention jig, thereby improving productivity and workability. It is an object of the present invention to provide an improved method for manufacturing a laminate, which can realize versatility of a jig.

[0007]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems by providing a stripping prevention jig in which a tongue and foot piece is suspended from an edge of a flat plate portion and stacking and forming. A method for manufacturing a laminated board, comprising: arranging a jig having a tongue and foot piece constituted by a fixing portion, a slide portion capable of adjusting the height along the fixing portion, and a stopper as the prevention jig. I will provide a.

The present invention also provides a stripping prevention jig itself for the above method.

[0009]

According to the present invention, the stripping prevention jig used at the time of lamination molding has a tongue and foot piece comprising a fixed portion and a slide portion, and the slide portion is adjusted to a required height position by a stopper. Therefore, the height can be freely adjusted according to the thickness of the laminated board product and the number of sheets to be molded, and the laminate can be formed. This adjusted height of the tongue and foot allows stripping to be prevented.

Therefore, it is not necessary to manufacture and prepare several types of jigs having different heights of the tongue and foot pieces as in the related art, and it is not necessary to use a dummy board for molding. The productivity and workability of the lamination molding are greatly improved. Of course, the method of the present invention having such an effect is not limited to the formation of a laminate for a printed wiring board, but is effective in, for example, the heating and press-forming of various laminates.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view showing a method of manufacturing a laminate according to the present invention. FIG. 1 illustrates a stripping prevention jig used in the method of the present invention. For example, as illustrated in FIG. 1, the stripping prevention jig of the present invention has a tongue and foot piece (2) suspended at an appropriate position on the edge of the flat plate part (1), and the tongue and foot piece is provided. According to (2), stripping of a plate material such as a prepreg, a resin sheet, or a metal foil during lamination molding is prevented.

The tongue and foot piece (2) is fixed to the fixing portion (2).
1), a slide portion (22) that slides up and down along the same, and a stopper (23) that fixes the slide portion (22) at a required position. The slide portion (22) is moved up and down, the height (H) of the tongue foot piece (2) as a whole is adjusted to a required height, and fixed by the stopper (23).

FIG. 2 is an enlarged view of the tongue and foot piece (2). With respect to the height (B) of the fixing part (21),
The slide portion (22) is slidable up and down within the range of the height (A), so that the height (H) of the tongue foot piece (2) as a whole can be freely adjusted. That is, the tongue and foot piece (2) has a double structure by the fixing part (21) and the sliding part (22).

The stopper (23) can be a suitable means such as a bolt. Usually, the jig including the stopper (23) is made of metal,
Manufactured by alloy. In order to increase the strength of the tongue-and-foot piece (2), for example, as illustrated in FIG. It is also effective to adopt a configuration of a shape. Any structure can be adopted as long as the stripping prevention function is not impaired.

The height (A) of the slide portion (22) shown in FIG. 2 is preferably equal to or less than the height (B) of the fixed portion (21), that is, A <B. In fact, when the above-described stripping prevention jig was used to form a laminate for a printed wiring board having a different product thickness and a different number of products, the difference in the height of the tongue and foot piece (2) (H) could be handled by one jig freely adjusted, and stripping could be effectively prevented.

[0016]

According to the present invention, as described in detail above, the height of the tongue and foot pieces can be freely changed, so that the height can be freely adjusted according to the thickness of the laminated board product and the number of molded articles. Enables stripping prevention. Jig versatility,
Productivity and workability are greatly improved.
