Further, a top plate and a carrier plate are arranged above and below on the outside, and it is generally obtained by lamination molding by heating and pressurizing scissors between hot platens. In recent years, wholly aromatic polyamide fiber cloth has come to be used as the cushioning material because of its excellent heat resistance and durability.

When layers are piled up, unevenness of interference fringes called moiré phenomenon occurs in the cushioning material, and when this cushioning material is used for lamination molding at a high pressure of 80 to 150 kg/cm2, the surface of the metal foil-covered laminate has large irregularities.

This prevents the weave from synchronizing, and at the same time fills the gaps between the unevenness with the resin eluted from the prepreg, resulting in a more homogeneous cushioning material. For this reason, the moiré phenomenon does not occur in the cushioning material.

性状のものを言う。[0010] The prepreg is made of phenol, cresol,
These resin compositions containing epoxy, unsaturated polyester, melamine, polyimide, polybutadiene, polyamide, polyamideimide, fluorocarbon resin, etc. alone, modified products, mixtures, and inorganic fillers are used, and if necessary, water is added to adjust the viscosity. methanol, acetone, methyl ethyl ketone,
The resin composition is semi-cured by impregnating a base material as a varnish containing a solvent such as cyclohexane, styrene, dimethylformamide, etc. and drying it. As the resin composition, epoxy resin compositions are preferred because they have excellent adhesive properties and electrical properties, and polyimide resin compositions are preferred because they have excellent heat resistance. As the base material, woven fabrics, nonwoven fabrics, or paper made of inorganic fibers such as glass, organic synthetic fibers such as polyester, polyamide, and acrylic fibers, and natural fibers such as cotton, or a combination thereof can be used. In particular, glass-based materials are preferable because they have excellent heat resistance. Conditions for obtaining this semi-cured prepreg include a drying temperature of 110 to 160°C. 160℃
If the resin is dried beyond this point, the curing of the resin will proceed too much or the drying operation will become difficult, which is undesirable. Semi-cured prepreg is in what is generally referred to as the B stage in the curing process of thermosetting resin, and when heat is applied, the resin remelts and the curing reaction progresses, making it easy to handle. It does not feel sticky to the touch and can be stacked on top of each other.

Approximately 1 to 15 sets of pressurized bodies made of prepreg 3 of the same or different type as the prepreg 3 inserted into the cushioning material 1 and metal foil 4 sandwiched between metal plates 5, 5 are stacked, and the present invention is placed on the outside thereof. A top plate 6 and a carrier plate 7 are placed one above the other with the cushioning material 1 interposed therebetween, and the top plate 6 and the carrier plate 7 are placed between the hot platens 8 and 8 to form a laminated sheet under heat and pressure to obtain a metal foil-clad laminate. As the conditions for this heating and pressure lamination molding, ordinary conditions can be applied as they are.

ある。[Function] When two or more sheets of wholly aromatic polyamide fiber cloth are layered together, there will be areas where pressure is applied more often and areas where it is less likely to be applied due to the synchronization of the weave. By interposing the prepreg between the wholly aromatic polyamide fiber cloths, the weave synchronization can first be relaxed. Furthermore, the resin eluted from the prepreg moves from areas where pressure is often applied to areas where pressure is less likely to be applied. This movement of the resin equalizes the degree of filling of the cushioning material and prevents the moire phenomenon of the cushioning material. Therefore, pressure is applied uniformly, and no unevenness occurs on the surface of the metal foil-clad laminate even when molded under high pressure of 80 to 150 kg/cm2.

。[0015] Furthermore, if a cushioning material is used which is formed by laminating heat and pressure as an adhesive layer and integrating a prepreg layer between a plurality of wholly aromatic polyamide fiber cloths,
The prepreg resin eluted during this hot-pressure lamination molding moves from areas where pressure is often applied to areas where it is less likely to be applied, making the degree of filling of the cushioning material uniform, and using cured material that eliminates the moiré phenomenon of the cushioning material. As a result, the pressure is applied more evenly, and the
Even when molded under high pressure of ~150 kg/cm2, no unevenness is produced on the surface of the metal foil-clad laminate. Furthermore, since the cushioning material is integrated, it is possible to build up the pressurized body and make it more efficient to install it between the hot platens.

A stainless steel metal plate with a thickness of 2 mm is arranged between and on the outermost side of each of the 10 pairs of pressurized bodies made by stacking 8 sheets of prepreg and 35 μm thick copper foil with adhesive, one on top and one on the top. 3 on the outside
Triple-weave fully aromatic polyamide fiber cloth (Teijin Conex, CO1033,920 g/m2)
Between each step, a 0.18 mm thick E-glass cloth was impregnated with epoxy resin varnish and dried in a dryer at 140°C for 45 minutes. After placing the top plate and carrier plate, place them between heating plates and heat to 160℃ and pressure 1.

められなかった。Example 2 In place of the cushioning material of Example 1, three four-ply woven fully aromatic polyamide fiber cloths (Conex, C, manufactured by Teijin) were used.
A cushioning material with a prepreg obtained by impregnating an E glass cloth with a thickness of 0.18 mm with epoxy resin varnish and drying it for 45 minutes in a dryer at 140 °C was heated at a temperature of 160 °C. °C, pressure 4
1. In the same manner as in Example 1, except that a cushioning material formed by lamination molding at 0 kg/cm2 for 60 minutes was used.
A 6 mm double-sided copper-clad laminate was manufactured. When a straight tube of a fluorescent lamp was reflected on the surface of this double-sided copper-clad laminate and surface unevenness was determined based on the degree of reflection, the straight tube of the fluorescent lamp was clearly reflected and no unevenness was observed.

れた。Comparative Example 1 A 1.6 mm double-sided fabric was prepared in the same manner as in Example 1, except that three triple-weave wholly aromatic polyamide fiber cloths were used as the cushion material in place of the cushion material in Example 1. Copper-clad laminates were manufactured. When a straight tube of a fluorescent lamp was reflected on the surface of this double-sided copper-clad laminate and surface unevenness was determined based on the degree of reflection, it was found that the straight tube of the fluorescent lamp was blurred and uneven.

面に凹凸の無い金属箔張り積層板を得ることができる。[Effects of the Invention] Since the cushioning material of the present invention does not have a moire phenomenon, even if this cushioning material is laminated under high pressure, it is possible to obtain a metal foil-clad laminate with no surface irregularities. Further, by using the cushioning material in which the wholly aromatic polyamide fiber cloth and the prepreg are integrated, it is possible to obtain a metal foil-clad laminate with even less irregularities on the surface.
