Abstract:
1. A compression molding apparatus for sealing an electronic component, the apparatus comprising: a lower mold section provided with a cavity; an upper mold section opposed to said lower mold section, wherein said upper mold section is capable of mounting thereon a substrate loaded with an electronic component; a resin supply portion capable of supplying a liquid base resin and a liquid curing agent; and a nozzle including a rotatable spiral supply member having a spiral structure for generating a mixed liquid resin by mixing said liquid base resin and said liquid curing agent supplied from said resin supply portion, said nozzle extending horizontally between said upper and lower mold sections, wherein said nozzle is capable of discharging said mixed liquid resin to fall into said cavity by gravity, wherein said mixed liquid resin flows as a whole along a strictly horizontal direction immediately prior to said discharge, wherein said upper and lower mold sections are capable of closing after removing said extending nozzle from between said upper and lower mold sections so as to dip said electronic component into said mixed liquid resin discharged into said cavity, and wherein said horizontal nozzle extension and said horizontal resin flow result in a downsize of the compression molding apparatus by a reduction in distance between the upper and lower mold sections.
