Abstract

PURPOSE:To prepare a laminate board free from warpage, by cutting off the excessive resin parts of the laminate board generated to both sides thereof at the time of preheating curing. CONSTITUTION:A substrate 2 such as paper is immersed in a varnish tank 5 to be impregnated with a thermosetting resin. Subsequently, a required number of the substrates are stacked and passed through a pair of upper and lower squeeze rolls 6 and adhered under pressure to form a laminated base material 3. Next, this laminated base material 3 is preheated by heaters 9 to be subjected to preparatory curing (to a degree not fluidizing the impregnated resin). Then, a metal foil 8 is adhered to this pre-cured base material 3 through a laminate roll 7. Thereafter, tab parts 4, 4 comprising the excessive resin formed to both sides of the base material 3 are cut off by a cutter 13. Finally, the trimmed one is perfectly cured in a heating drying oven 10. The obtained laminated base material becomes uniform in strain and residual stress and generates almost no warpage or twisting.

However, when the resin was preheated and precured, the curing shrinkage of the edges formed by the excess resin that flowed out from both sides of the laminated base material caused the curing shrinkage of the laminated base material of the main body. This is larger than the curing shrinkage rate, and the strain residual stress on both sides of the laminated base material near the ears is larger than that at the center of the laminated base material, resulting in large warps and twists in the fully cured laminate. have done.

。[Disclosure of the Invention] In the manufacturing method of the present invention, a required number of base materials 2 impregnated with a thermosetting resin 1 are bonded together to form a laminated base material 3, and then this laminated base material 3 is preheated. The impregnated resin is precured to the extent that it does not flow, and then the ears 4 formed with excess resin on both sides of the laminated base material 3 are cut, and then the laminated base material 3 is heated to completely cure the resin. It is characterized by being cured, and with this configuration, the above object can be achieved. That is, before the resin of the laminated base material 3 is completely cured, by cutting off the edges with a large curing shrinkage rate,
The strain residual stress of the laminated base material 3 can be made uniform.

As shown in FIG. 1, a base material 2 such as paper or glass cloth is unwound from a take-up roll 11, and a varnish bath 5 of a thermosetting resin 1 such as phenol resin, epoxy resin, area resin, unsaturated polyester resin, etc. Thermosetting resin 1 is applied to base material 2 through
is impregnated via the dipping roll 12. Next, a required number of base materials 2 (four in this example) are passed between a pair of upper and lower squeeze rolls 6 and pressed together to form a laminated base material 3. Thereafter, the laminated base material 1 is preheated in a heater or a preheating furnace to be precured. Here, precuring refers to the degree to which the impregnated resin does not flow. Note that the preheating may be performed after laminating the metal foil 8. Next, metal foils 8 such as copper foil or aluminum foil are attached to the upper and lower surfaces of the base material via a laminating roll 7. Thereafter, as shown in FIG. 2, the edges 4 made of excess resin formed on both sides of the laminated base material 3 before being precured are cut off by a cutter 13. Next, the laminated base material 3 from which the ears 4 have been cut is sent into a heating drying oven 10 and heated under no pressure, for example, at 120° C.
The thermosetting resin M1 is completely cured in minutes. In this way, a metal-clad laminate A is obtained. 250 x this thing
Sample A1 was cut to 250+ am, and as shown in Fig. 3, the three corners were held down and supported at three points on a surface plate, and the lifting height H (mm) of the remaining point was measured, and it was found to be 0.

By cutting the edges that have a high curing shrinkage rate and are made only of thermosetting resin (fat), the strain and residual stress of the laminated base material can be made uniform, and the laminated base material is then heated. The laminate obtained by completely curing the resin has almost no warping or sagging.
