METHOD FOR MANUFACTURING MEMORY CARD

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing a memory card which can meet the need of increasing a storage capacity and is advantageous to the reduction of manufacturing cost.

SOLUTION: The method for manufacturing a memory card comprises steps for: providing a member 34 for substrate molding configured of a substrate 14 and an external board 32 connected through an arm 30 to the substrate 14; positioning the substrate 14 so that the substrate 14 can be positioned in a cavity 38C and placing the member 34 for substrate molding on a lower mold 38B; closing the lower mold 38B and an upper mold 38A and sandwiching the arm 30 by those molds 38; injecting a synthetic resin material in a fusing state into the cavity 38C thereby molding a memory card 10 connected through the arm 30 to the external board 32; opening the mold 38 after the synthetic resin material is hardened, and extracting the member 34 for substrate molding in which the memory card 10 has been molded; and cutting the arm 30 and separating it from the external board 32 thereby obtaining the memory card 10.
