Liquid crystal polymer film, laminate, method of making them and multilayered parts mounted circuit board |
摘要 |
<p>A polymer film capable of forming an optically anisotropic melt phase is, after having been laminated on a base material capable of supporting the shape of the film during heat treatment, is heat-treated at a temperature of from the thermal deformation temperature Tdef of the film to a temperature lower by alpha ( alpha = 10 to 35 DEG C) than the melting point Tm of the film until the fusion peak temperature TA of the film attains a temperature which is higher by beta ( beta = 5 to 30 DEG C) than the melting point Tm of the film before the heat treatment and is subsequently heat-treated at a temperature of from a temperature not lower than the melting point Tm of the film to a temperature lower than the fusion peak temperature TA for a length of time over which the TA increases by gamma ( gamma = 5 to 20 DEG C), and thereafter the base material is removed to produce the film. <IMAGE></p> |
