发明名称 Method for molding semiconductor components
摘要 A molding apparatus for molding semiconductor components includes a pair of opposing mold chases having mating mold cavities. The mold cavities are configured to retain polymer release films for separating the molded components from the mold cavities. The molding apparatus also includes a movable pot having a reservoir for retaining a preform of molding compound, and a plunger for moving the molding compound into the mold cavities. The movable pot is mounted for axial movement within a chamfered opening in one of the mold chases. The movable pot is configured to clamp onto the release films to prevent wrinkling of the release films, and seepage of the molding compound under the release films. A system for molding semiconductor components includes the molding apparatus, a pot drive mechanism for moving the movable pot, a plunger drive mechanism for moving the plunger, and a clamping mechanism for clamping the mold chases together. A molding method includes the steps of providing the molding apparatus, placing the release films in the mold cavities, clamping the release films to one of the mold chases, and then injecting the molding compound into the mold cavities.
