PACKAGE CARRIER AND MANUFACTURING METHOD THEREOF

摘要

A manufacturing method of a package carrier includes the following steps. Firstly, two base metal layers are bonded together. Then, two supporting layers are laminated onto the base metal layers respectively. Next, two release metal films are disposed on the supporting layers respectively, wherein each of the release metal films includes a first metal film and a second metal film separable from each other. Next, two patterned metal layers are formed on the release metal films respectively, wherein each of the patterned metal layers is suitable for carrying and electrically connected to a chip. Then, the base metal layers are separated from each other to form two package carriers independent from each other. A package carrier formed by the manufacturing method described above is also provided.

1. A manufacturing method of a package carrier, comprising:
bonding two base metal layers; laminating two supporting layers onto the base metal layers respectively; disposing two release metal films on the supporting layers respectively, wherein each of the release metal films comprises a first metal foil and a second metal foil separable from each other; forming two patterned metal layers on the release metal films respectively, wherein each of the patterned metal layers is capable of carrying and electrically connected to a chip; and separating the two base metal layers from each other to form two package carriers independent from each other.
