板の製造方法を提供することを目的とする。It is impossible to create a laminate that can be processed into a fixed multifaceted shape using the above-mentioned rigid substrate. Although the flexible wiring board can be processed into a multifaceted shape, the shape cannot be maintained. To solve this problem,
As shown in No. 4587, there is a method of impregnating a nonwoven fabric made of glass fibers mixed with polyester fibers with a thermosetting resin and using a filtrate obtained by impregnating a thermosetting resin. However, in this method, if the flexibility of the resin is not appropriate, bending occurs along the lines during manufacturing of the printed wiring board, resulting in poor workability. In addition, it is difficult to obtain optical soldering heat resistance due to the influence of fragility, and it cannot be used for mounting components such as semiconductors and resistors. It is an object of the present invention to provide a method for manufacturing a laminate that can be easily processed into a fixed multifaceted shape.

亀裂及び破損を生ずるおそnがある。Flexible thermosetting resins include epoxy resins, unsaturated polyester resins, phenolic resins, melamine resins, polyimide resins, etc.? Use it. If you use epoxy resin, use a flexible epoxy resin that has been cured for internal use. That is, dimer 1! f-type epoxy resin, polyester-modified epoxy resin, polyamine f-type epoxy resin, or polyphtadiene-modified epoxy resin. When using a zero-unsaturated polyester resin, which can also be used in combination, the acid component is: The monomer may be an unsaturated dibasic acid anhydride such as maleic anhydride, or a saturated dibasic acid such as terephthalic acid.As the glycol component, ethylene glycol, propylene glycol, or diethyl glycol may be used. Styrene monomers may be used.To make flexible thermosetting resins flame retardant, flexible brominated epoxy resins are used or brominated adducts are added or reacted.Talesol novolac type epoxy resins are Ordinary materials may be used, and if the total addition is 5 to 15% to the above flexible thermosetting resin, and if the amount is less than 0.5%, due to the flexibility of the thermosetting resin, etching during production of printed wiring boards may be required. There is a possibility that bending may occur in the process and the paulownia process, resulting in poor workability, and it may not be possible to obtain sufficient solder heat resistance due to the fragility. At 15% or more, bending will occur during processing.
There is a risk of cracking and damage.
