PACKAGE SUBSTRATE, MANUFACTURING METHOD THEREOF, AND MOLD THEREFOR
First Claim
1. A method of manufacturing a package substrate, the method comprising:
- preparing a chip component and a substrate;
mounting the chip component on a main surface of the substrate;
preparing a mold having a cavity and protrusions formed on a ceiling surface thereof;
disposing the substrate on a bottom surface of the mold such that the chip component is positioned within the cavity; and
forming a resin sealing body that collectively hermetically seals the chip component and the main surface of the substrate by injecting a pressurized liquid resin into the cavity.
