RESIN SEALING APPARATUS AND RESIN SEALING METHOD

摘要

A lower mold has a bottom surface member and a side surface member. An upper end surface of the bottom surface member forms an inner bottom surface of a cavity and has a planar shape corresponding to an unusual planar shape of a sealing resin. A substrate is disposed on a mold surface of an upper mold such that a component to be sealed attached to the substrate faces downward, and the cavity is filled with a fluid resin. The upper mold and the lower mold are clamped, and the component is immersed in the fluid resin. The bottom surface member is raised, and the fluid resin is pressed at a prescribed resin pressure and cured to form the sealing resin. The bottom surface member and the side surface member are moved relatively, and thereby, a molded product is released from a mold surface of the lower mold.

主权项

1. A resin sealing apparatus for providing resin sealing for a component to be sealed by a sealing resin which is cured in a cavity, comprising:
an upper mold on which a substrate is disposed, a component to be sealed being attached to the substrate; a lower mold provided to face the upper mold; a cavity provided at least in the lower mold; a bottom surface member forming an inner bottom surface of the cavity; a side surface member forming a side surface of the cavity; an opening provided in the side surface member and corresponding to an outer circumference of the bottom surface member; an opening circumferential edge portion provided in the side surface member and having an inner edge shape formed to correspond to an outer edge of an end surface planar shape, an end surface of the sealing resin having the end surface planar shape; and an inclined surface portion provided in the side surface member and inclined to expand upwardly from the opening circumferential edge portion, the side surface member being fitted to the outer circumference of the bottom surface member so as to be slidable on the outer circumference, and the end surface planar shape being an unusual planar shape.
