Alloys and the like can be mentioned, and copper is preferable. In particular, a rolled copper foil product whose rigidity is so low that its use has been avoided because of difficulties in pressure control can be suitably used. Further, for the purpose of improving the adhesive strength, the surface may be subjected to a chemical or mechanical surface treatment such as a plating, nickel plating, copper-zinc alloy plating, or an aluminum alcoholate, an aluminum chelate, or a silane coupling agent. A single-sided conductor laminate in which a polyimide resin is heat-cured and adhered as an insulating layer to one surface of such a conductive metal foil (M) without an adhesive is obtained by the manufacturing method disclosed in Patent Document 1. Can be used.

- a low thermal expansion material a thermoplastic polyimide which melts or softens when heated, or the like can be used, and is not particularly limited.
- a preferred insulator layer is composed of a base layer composed of a thermoplastic polyimide resin obtained by heating and curing a polyimide precursor resin solution described in Patent Document 1, and a main layer composed of a low thermal expansion polyimide resin. It is also desirable that at least three polyimide resin layers, which are top layers made of thermoplastic polyimide resin, also have a layer strength.

- the pair of heated press rolls is desirably processed into a roughened state in which the surface roughness (R) of the press roll is 0.01 to 5 ⁇ m, preferably 0.1 to 3 ⁇ m. . If the surface roughness (R) of the press roll is 0.01 ⁇ m or less, the double-sided conductor polyimide laminate coming out from between the heating rolls will stick to the roll due to roll adhesion, and a seam will occur during running. When the thickness is 5 ⁇ m or more, unevenness on the roll surface is transferred to the surface of the laminate, which is not preferable.
- the roughened surface of the roll can be adjusted by spraying a ceramic film such as silicon nitride.
- the surface roughness (Ra) is determined by a stylus type surface roughness meter using a diamond needle.
- FIG. 1 is a schematic flow chart showing a method for producing a double-sided conductor polyimide laminate in which a single-sided conductor laminate of the present invention and a conductive metal foil are introduced between a pair of press rolls and laminated by heating and pressing.

- These conductive metal foils (M) 2 have a plurality of
- a plurality of guide rolls 3, 3, 4, 4, 4, 8, 8 'and a pair of heated press rolls 5, 6 are treated in a nitrogen gas atmosphere at atmospheric pressure or higher to prevent oxidation of the conductive metal foil.
- a nitrogen seal mechanism (labyrinth seal) 11 be provided in the chamber 10 and provided at the base material inlet and the laminate outlet.
- the heating press rolls 5 and 6 are arranged vertically with the center axis being horizontal, though not shown.
- the base material to be introduced by holding at least one of the placed press rolls on both sides of the center axis and moving the press roll to a predetermined position to the other by hydraulic or gear pressing means to adjust the gap between the two.
- Optimal pressing force is transmitted to 1 and 2 mutually.
- a press roll of a normal heating method one of the press roll and the base material when the gap adjustment is ideally performed when narrowing the gap between the two is idealized as shown in Fig. 2 (a).
- Contact state (however, the other press roll is omitted).
- the roll to be moved has a deflection of several microns due to the deflection caused by holding both ends and the marginal force of machine accuracy. It is unavoidable to lean in equilibrium.
- the present invention adopts a configuration in which a crown state is generated by thermal expansion in the center area of the roll, thereby absorbing the gap caused by the central axis of the roll being tilted in minute micron units. is there.
- FIG. 3 shows an example of a heated press roll of the present invention suitable for causing a crown state due to thermal expansion in a central zone portion of the press roll.
- the outer peripheral portion of the cavity and the fixed center shaft 12 that also protrudes both ends are integrally formed via a rotation support member 13 such as a bearing disposed inside both ends of the outer peripheral portion of the roll.
- a rotation support member 13 such as a bearing disposed inside both ends of the outer peripheral portion of the roll.
- Heating means 14, 15, and 16 for heat radiation and radiation are fixed to the central axis 12 at three locations, a central zone and an end zone.
- the heat radiation to the inner wall surface of the press roll or the heat energy to be irradiated is controlled.
- the central wall portion is thermally expanded by heating the inner wall surface of the central band portion to a temperature higher by 5 to 20 ° C, preferably 715 ° C than the inner wall surfaces of the both side band portions, and the press roll is heated.
- Non-uniformity of the pressing force due to the slight inclination at the time of gear adjustment can be automatically corrected. If the temperature difference is 5 ° C or less, the thermal expansion is too small. If the temperature difference is 20 ° C or more, it becomes difficult to make the roll surface temperature uniform, which is not preferable.
- a jacket or a heat pipe 17 that exhausts an organic heat medium with good heat conductivity or a small amount of a volatile liquid (working fluid) is used to equalize the surface temperature. Conductive elements are embedded.
- the strong heat pipe is instantaneously transmitted to the entire outer surface of the roll by the heat transfer from the heating means 14, 15, 16 of the central shaft 12, so that there is almost no axial temperature difference that increases the surface temperature accuracy.
- the heating temperature of the roll surface temperature is desirably equal to or higher than the glass transition point of the thermoplastic polyimide resin, and more preferably 350 to 390 ° C. It is desirable to control the heating temperature by using a temperature sensor embedded in the roll surface and to control the current value supplied to the heating means.
- the pair of heated press rolls is moved under a nitrogen atmosphere by moving at least one press roll of the pair of press rolls arranged above and below to a predetermined position to form a pair of press rolls arranged above and below the two.
- the surface pressure between the press rolls at least one of the press rolls is moved to a predetermined position to narrow the gap between the two, and the pressing force is transmitted between the press rolls through the introduced base material.
- the linear pressure between the press rolls is 50-500Kg / cm (490N / cm-4900N / cm), preferably 100-300KgZcm (980NZcm-2940N / cm), and the heating time is 2-5 seconds. It is desirable to crimp.
- a pair of heated press rolls to be used is used in a roughened state in which the surface roughness (R) of the press roll is 0.01 to 15 ⁇ m, preferably 0.1 to 3 ⁇ m. It is desirable. If the surface roughness (R) of the press roll is 0.01 ⁇ m or less, the double-sided conductor polyimide laminate coming out from between the heating rolls will stick to the roll due to the roll contact, causing a seam during running. If it is 5 m or more, the unevenness of the roll surface is transferred to the laminate surface, which is not preferable. To make the roll surface rough within the above range, it can be adjusted by spraying a ceramic coating.
- a heat pipe filled with naphthalene is embedded near the surfaces of the heating press rolls arranged vertically above and below the central axis to control the surface at a set temperature of 360 ° C, and the central axis as a means of heating internal force
- the heating coil is divided into three parts, and the total output (heat quantity) is constant and the ratio of the flowing current is changed (the heating coil at both ends is 30% with respect to the heating coil at the center part is 30%).
- a temperature difference of 10 ° C was generated in both side zones.
- an insulating layer made of a polyimide resin is heat-cured and adhered on one side of a rolled copper foil product (M) having a thickness of 20 ⁇ m, and the thickness is 45 mm from the roll-wound state and the width is 500 m.
- the two-layer base material consisting of a single-sided conductor laminate having a thickness of 20 m and a rolled copper foil product (M) having a width of 500 mm and a width of 500 mm from a rolled state was passed through a heated press roll and laminated integrally.
- FIG. 4 the vertical axis represents the pressing force at the time of adjusting the gap between the press rolls, and the state of contact of the base material with the upper press roll surface is shown in FIG. Fig. 4 (a) shows the initial stage of contact where a gap is formed at both ends of the base material due to a crown state due to thermal expansion at a low pressure.
- Figures 4 (b) and 4 (c) show the stage where the pressing force between the upper and lower press rolls is appropriate and they are pressed against each other in a crown state to maintain the optimal flattened contact state. This shows a case where the pressurizing force between the press rolls is excessive and a gap is formed between the press roll and the substrate at the center of the press roll.
- Step (a) is a case where the oil pressure is less than or equal to each It, and generation of a large number of shies was observed on the surface of the laminated one-piece product.
- Stage (d) is a case where the hydraulic pressure is 20 t or more, and many vertical wrinkles were observed on the surface.
- the above-described heating press roll of the present invention is capable of continuously thermocompression bonding thermoplastic resins and thermosetting plastic films on the surfaces of plastic films or sheets, or on the surface of cloth, paper, metal foil, or the like. Also suitably used for laminating below. Particularly preferably, it is used for a continuous production method of a double-sided conductor type polyimide laminate, but the obtained laminate has a conductive metal layer as a conductor on both sides of a polyimide resin layer as an insulator and has a good appearance.
- the method for producing a double-sided conductor polyimide laminate of the present invention comprises continuously rolling a double-sided conductor polyimide laminate in a roll-wound state with a stable double-sided conductor polyimide-based laminate having no appearance defects such as vertical wrinkles. This is a manufacturing method with high industrial applicability that can be manufactured in a simple manner.
