Patent ID: 6977188

Claim:
A resin encapsulation molding method for resin encapsulating an electronic part, comprising steps of: preparing a first mold having a first main mold surface; preparing a second mold having a second main mold surface opposed to said first main mold surface; preparing a third mold that forms a mold side surface between said first main mold surface and said second main mold surface; fitting an electronic part into said first mold; closely contacting a release film to said second main mold surface by sandwiching said release film using said second mold and said third mold to apply a prescribed tension to said release film; clamping said first mold, said second mold and said third mold to form an enclosed space that includes said electronic part by using said first main mold surface, said second main mold surface and said mold side surface; maintaining a clamped tensioned state and position of said release film to avoid contact between said release film and said electronic part; filling said enclosed space with a molten resin; and providing resin encapsulation molding to said electronic part by curing said molten resin.
