  • Patent number: 5300619
    Abstract: A resin film useful mainly for fabricating flexible printed circuits, and a method of producing same. In the process of fabricating a flexible printed circuit board, a copper foil(2) is thermally bonded to a resin film(1), and the copper foil(2) is then etched to a predetermined pattern, in which case the board is generally subject to some dimensional change. In order to minimize such dimensional change it is arranged that the ratio(a/b) of the linear expansion coefficient(a) of the resin film(1) in the direction of mechanical feed(MD direction) to the linear expansion coefficient(b) of the resin film(1) in a direction perpendicular to the MD direction (TD direction) is more than 0.2 but less than 1.0 and that the linear expansion coefficient in MD direction is 0.4-2.0.times. 10.sup.-5 .degree..sup.-1. For such resin film is used a polyimide film containing more than 90% of a recurring unit expressed by a specified general formula. To produce such a resin film, film 1 is drawn by a factor of from 1.0 to 1.
