Abstract: Disclosed herein is a substrate processing system, including: a feeding apparatus which feeds a substrate including a plurality of unit substrates into the substrate processing system; a vacuum molding apparatus which molds the substrate fed by the feeding apparatus; a paste printing apparatus which prints a solder paste on the substrate molded by the vacuum molding apparatus; a mounting apparatus which mounts an electronic device on the substrate on which the solder paste is printed; and a reflow apparatus which performs a reflow on the substrate on which the electronic device is mounted, wherein the vacuum molding apparatus includes a substrate molding control unit which controls the molding of the substrate. Therefore, the warpage (CAW) of the substrate is limitedly formed to improve the warpage (CAW) dispersion of the substrate, thereby improving bonding reliability and a mounting yield between the chip die and the bump of the substrate.
