A surface of a flexible circuit board (referred to as a flexible board) formed of a base film made of a thermoplastic resin such as polyimide, and a sheet of copper foil or the like which is patterned as a laminated material or etched in a later step. There is a step of laminating the conductive layer in the form of a film or a film by applying pressure and heat. In addition, in order to protect the laminated copper foils from etching, plating, solder, etc. on the glass substrate or flexible substrate as the material to be laminated, a sheet-shaped or film-shaped photoresist forming layer is used as the laminated material. There is a step of thermocompression bonding to the surface of the substrate. In general, the film-like photoresist forming layer is composed of a support film and a photosensitive layer, has tackiness when heated, and is laminated on the surface of the substrate under pressure. As still another example of the laminated molding material, there is a case where the surface of a glass plate as a material to be laminated and a film having a polarization effect or the like as a lamination material are laminated by pressing and heating. .

The voids are apt to occur due to volatile components, air bubbles such as air remaining between the laminated moldings, and wrinkles. The generated voids, for example, a molten solder bath, may expand during high-temperature processing in a subsequent process and may damage the laminated copper foil or the film-like photoresist forming layer. There is a risk of causing poor conductivity. In addition, even when a film is laminated on the surface of a glass plate, when air bubbles are generated due to air remaining between the two and wrinkles are generated in the laminated film, the laminated molding is performed. Not only will the surface of the product not look good, but there will be problems such as the inability to obtain the polarization effect as set.

As described above, it has been conventionally practiced to laminate-mold a laminated molding material in a vacuum atmosphere. Further, these laminated molding materials are required to be uniformly pressed and laminated so as to have a smooth surface.

In the one disclosed in Japanese Patent Publication No. 99895, a cylindrical rubber or a rubber sheet in a portion to which a pipeline of a vacuum pump is connected is closely adhered to each other and laminated by vacuum drawing in a molding space by a vacuum pump, and laminated. There is a problem in that the suction action of the vacuum pump does not reach the entire periphery of the molding material, and the residual air or the gas of the volatile component generated by heating becomes bubbles and causes voids. Further, in such a case, an unnecessary bent portion may be formed at a portion partially floating from the laminated molding material of the cylindrical rubber or the rubber sheet, or the cylindrical rubber or the rubber sheet may be formed in the vacuum pump pipeline. There is a problem in that deterioration is promoted by the inclusion of the. Furthermore, the pipe line of the vacuum pump is connected to the periphery of the tubular rubber or rubber sheet laminated molding material avoiding it, and furthermore, the tubular rubber or rubber sheet is removed by vacuuming the molding space by the vacuum pump. Since the pressure is applied to the laminated molding material, it is possible to partially pressurize the laminated molding material while the pressure inside the molding space is only partially reduced and the decompression between and around the laminated molding material is not sufficient. However, there has been a problem that the surface of the laminated molding material cannot be uniformly pressed to smoothly laminate the surface.

Then, in this embodiment, the jig 8 is inserted inside the frame body 4 and placed on the pressure film body 3. In the laminated molded material H, since the pressure film body 3 is provided on the lower plate 2 in this embodiment, the laminated material Hb should face the pressure film body 3 through the hole 80 of the jig 8. The jig is supported by a continuous belt-shaped carrier film (not shown) in a state of being positioned below and stacked so that the material to be laminated Ha is positioned above so as to face the upper surface plate 13. 8 is carried into the groove-shaped recess 81 so as to be aligned with the hole 80 (state of FIG. 1). After that, when the lower plate 2 is moved closer to the upper plate 1, the pressure film body 3 fixed to the frame body 4 and the pressure film body fixing frame 30 is sandwiched between the upper plate 1 and the lower plate 2. Thus, a closed molding space S accommodating the laminated molding material H is formed together with the jig 8.

With the surroundings of the laminated molded material H, the air permeability is secured without being blocked, and the communication state is maintained. Further, since the jig 8 is located between the opening 7 to which the pressure reducing means is connected and the pressure film body 3, the pressure reducing means sucks from the opening 7 and swells the pressure film body 3. When this is done, it is possible to prevent the pressure film body 3 from entering the gap F from the opening 7 and obstructing the suction of the pressure reducing means, and the pressure film body 3 being bent and damaged.

It is selected and used from resin films such as polyethylene terephthalate having a thickness of about m. In the case of this embodiment, since the peripheral edge of the laminated material Hb is not laminated and molded with respect to the laminated material Ha, only the inner portion is laminated and molded (see the portion indicated by the broken line in FIG. 7). As shown in FIG. 12, the shielding film 100 arranged between the laminated material Ha and the laminated material Hb has a laminated material such that the laminated material Ha and the laminated material Hb are partially in contact with each other. It is formed in the shape of a single window frame in which a window 101 is formed in a size and shape substantially the same as the inner portion of Hb to be laminated and formed. In addition, as the jig 8 used in this embodiment, as described in the above-described second embodiment, the jig in which the shield portion 82 is formed around the hole 80 is used. However, the size of the hole 80 of the jig 8 does not need to be formed to have substantially the same size and shape as the portion where the pressure film body 3 is laminated and molded as in the second embodiment, and the shielding film 100 is not necessary. Windows 101 or larger size
Any shape will do. Therefore, in this embodiment,
The jig 8 described in the first embodiment can also be used.
