  • Publication number: 20220063150
    Abstract: A resin molding apparatus includes: a resin supply mechanism including a nozzle for ejecting liquid resin to a supply target; a resin collection unit including: a resin-receiving member configured to receive a portion of the liquid resin which portion has dropped from the nozzle; and a movement mechanism configured to cause the resin-receiving member to move in such a manner as to follow the nozzle while keeping the resin-receiving member under the nozzle; a mold die including an upper die and a lower die facing the upper die; a mold clamp mechanism configured to clamp the mold die with the supply target between the upper die and the lower die; and a control section configured to control at least respective operations of the resin supply mechanism and the resin collection unit.

  • Publication number: 20150017372
    Abstract: The present invention is to provide a method of manufacturing a resin-encapsulated electronic component and an apparatus for manufacturing a resin-encapsulated electronic component that enable the manufacture of a resin-encapsulated electronic component including a plate-like member in a simple manner at low cost. The method of manufacturing a resin-encapsulated electronic component, the resin-encapsulated electronic component including a plate-like member 13, the method includes: placing a resin 15 on the plate-like member 13; transferring the resin 15 to a position of a die cavity 17a of a molding die in a state where the resin 15 is placed on the plate-like member 13; and performing resin-encapsulation of an electronic component by subjecting the resin 15 to compression molding together with the plate-like member 13 and the electronic component in a state where the electronic component is soaked in the resin 15 placed on the plate-like member 13 in the die cavity 17a.
