摘要

The present invention relates to a method for manufacturing a functionally graded composite material for a PCB, comprising the steps of: (a) manufacturing at least two types of mixed powders comprising (i) a metal powder including a powder consisting of aluminum or an aluminum alloy, and a magnesium powder, and (ii) a polymer or a ceramic powder, wherein the mixed powders are different in the content of the polymer or ceramic powder; (b) laminating the at least two types of mixed powders manufactured in step (a), so as to form a functionally graded laminate in which a fraction of the content of the polymer or ceramic powder with respect to the metal powder in each layer varies from the lowest layer portion to the uppermost layer portion; and (c) manufacturing a functionally graded composite material by atmospheric sintering or spark plasma sintering the functionally graded laminate.
