Abstract:
Disclosed herein are an electronic component package and a method of manufacturing the same. The electronic component package includes: a substrate; a connection member provided on at least one surface of the substrate; an active element coupled to the substrate by the connection member; and a molding part covering an exposed surface of the active element, wherein the molding part is formed of a first material having a coefficient of thermal expansion of 8 to 15 ppm/° C. and thermal conductivity of 1 to 5 W/m° C. Therefore, warpage may be significantly decreased and heat radiation performance of the active element may be improved, as compared with the case of implementing the molding part using an EMC according to the related art.
