The present invention relates to a method for manufacturing a conductive foil-clad laminate comprising three layers: a conductive foil, an insulating resin layer, and an iron base plate. In the conventional manufacturing method of conductive foil-clad laminates, an insulating resin layer 4 made of cloth impregnated with synthetic resin is used.
was directly laminated on the iron base plate 1', and the conductive foil 5' was laminated on the insulating resin layer 4'. ' had a problem in that it was easy to peel off. The present invention has been made in view of the above points, and its purpose is to provide a method for manufacturing a conductive foil-clad laminate that can improve the adhesion of an insulating resin layer to an iron base plate. There is something to do. In the present invention, an aluminum plating layer 2 is formed on the surface of an iron base plate 1, and the surface of the aluminum plating layer 2 is made into a rough surface 3 by mechanical polishing. The present invention relates to a method for manufacturing a conductive foil-clad laminate, which is characterized by laminating an insulating resin layer 4 impregnated with a synthetic resin and laminating a conductive foil 5 on the insulating resin layer 4. Hereinafter, the present invention will be explained in detail with reference to illustrated embodiments. Reference numeral 6 is an aluminum plated steel plate, which is formed by laminating an aluminum plated layer 2 on the surface of the iron base plate 1, and has a thickness of, for example, 1.0 mm.
It is as follows. The thickness of the aluminum plating layer 2 is, for example, 2μ or more, and the surface of the aluminum plating layer 2 is made into a rough surface 3 by mechanical polishing (sanding processing), and the depth of the rough surface 3 is 0.2μ or more on average, and 1.5μ or more at the maximum. It is set to be more than μ. 4 is an insulating resin layer with a thickness of, for example, 0.1 mm, which is made by impregnating a cloth such as glass cloth with a synthetic resin such as epoxy resin, and then adhering it to the rough surface 3 of the aluminum plating layer 2 and laminating it. There is. Furthermore, a conductive foil 5 such as copper foil is laminated on the surface of the insulating resin layer 4, and the thickness of the conductive foil 5 is, for example, 35 μm. In order to manufacture such a conductive foil-clad laminate, the surface of the aluminum layer 2 of the aluminum-plated steel plate 6 is made into a rough surface 3, and then the insulating resin layer 4 and the conductive foil 5 are superimposed and hot-pressed. The iron base plate 1 of the conductive foil-covered laminate functions as a ground and a heat sink, and an aluminum plating layer 2 is formed on both sides of the base plate 1, and an insulating resin layer 4 and a conductive foil 5 are laminated on both sides. When a through-hole laminate is used as shown in FIG. 3, the base plate 1 can be used as the core of the coil. 7 is a through hole, and a metal plating layer 8 is applied to the peripheral wall of the through hole 7.

Next, an insulating resin layer impregnated with synthetic resin is laminated on the base plate via an aluminum plating layer,
Next, conductive foil is laminated on the insulating resin layer, so the rough surface improves the adhesion between the aluminum plating layer formed on the iron base plate and the insulating resin layer.
This prevents the steel base plate from peeling off from the insulating resin layer, which is a problem with conductive foil-covered laminates in which an insulating resin layer is laminated on an iron base plate and conductive foil is laminated on top. This has the advantage that peeling of the insulating resin layer due to high heat can be prevented, and furthermore, peeling at the edges due to processing operations and peeling after boiling and immersion treatment can be prevented. In other words, since iron base plates are less likely to be roughened, compared to iron, an aluminum plating layer is formed on the iron base plate and the surface is roughened. It is possible to prevent the peeling off.
