化が少ないことがより必要となってきた。Generally, copper-clad laminates are made using epoxy resin.11) A coated cloth obtained by impregnating a base material such as glass cloth with a thermosetting resin varnish such as an epoxy resin modified with another resin and drying the coated cloth is generally used. It is manufactured by stacking two or more sheets together and hot-pressing them with copper foil for printed wiring boards interposed on at least one side. With regard to copper-clad laminates made in this way, such as glass cloth substrates, changes in board dimensions during the 9-circuit processing process have been made in recent years due to progress in automation of mounting high-density components on printed circuit patterns. Less has become more necessary.

難にしていた。Conventional glass cloth substrates have a large change in one dimension, and a particularly large difference in the direction of the change in dimension, making it difficult to automate the mounting of components that require high precision in circuit position dimensions. In other words, the dimensional change of the base material during one circuit processing process was conventionally -0,042% in the warp direction and -0,0% in the weft direction.
18%, a large difference in the rate of change and the direction of the rate of change occurred, making it difficult to automate component mounting, which requires high dimensional accuracy.

とを特徴とするものである。The present invention has been made in view of these points, and consists of overlapping a required number of prepregs made by impregnating a base material with a thermosetting resin with copper foil on at least one side, and heating and pressing the copper foil. In the method for producing a tension laminate, the prepreg impregnates a thermosetting resin into a fiber cloth base material having a tensile modulus (warp/latitude) of 0.9 to 1.1 in the warp and weft directions. It is characterized by being a thing.

An epoxy resin varnish containing dicyandiamide as a curing agent and 2-ethyl-4-methylimidazole as a curing accelerator is impregnated with R511 (trade name manufactured by Dow Chemical Company) with a resin content of 40 to 47% by weight, and a curing time of 150 to 220 seconds. A coated cloth was obtained by drying the coated cloth so that the resin flow was 5 to 15% by weight, and two sheets of this were stacked and then hot-press molded with copper foil for printed wiring boards interposed above and below to produce a copper-clad laminate. The copper-clad laminate thus obtained was subjected to measurement of nine dimensional changes under heating conditions of 170° C. for 30 minutes according to the J I 5-C-6486 method.
