Provided is a thick layer polyimide metal clad laminate, and more particularly, a thick layer polyimide metal clad laminate for producing a product with excellent process stability and superior dimensional stability. Specifically, the present invention is directed to providing a thick layer polyimide metal clad laminate, in which a polyimide laminate and a metal foil, which is on one side or both sides of the polyimide laminate, are attached by a lamination process, wherein the polyimide laminate includes a polyimide film and a thermoplastic polyimide layer formed on one side or both sides of the polyimide film, the polyimide film having an elongation of 30% or less, and a tensile modulus of 3GPa or more, which is measured by IPC-TM-650 (2.4.19) method, and a coefficient of thermal linear expansion (CTE) of 5 to 30ppm/?, which is calculated from 100 to 250?. |
