Abstract
A manufacturing method of a package carrier is provided. A carrier having a connecting surface is provided. A releasable solder resist layer is formed on the connecting surface of the carrier and completely covers the connecting surface. A substrate having an upper surface and a lower surface opposite to each other is provided. A first patterned solder resist layer is formed on the lower surfaces of the substrate and exposes a portion of the lower surface. The carrier and the substrate are laminated, the releasable solder resist layer directly contacts the first patterned solder resist layer, and the carrier is temporarily bonded to the first patterned solder resist layer through the releasable solder resist layer.
