Patent ID: 7887313

Claim:
A mold apparatus for resin encapsulation, wherein a peripheral edge portion of a substrate board, on which electronic components are mounted, is clamped by both an upper mold disposed in a lower surface of an upper mold set and a lower mold disposed in an upper surface of a lower mold set, wherein cavities are formed, a resin for encapsulation, which is inserted into pots provided in any one of the mold sets, is fluidified through plungers, and the melted resin is filled in the cavities, whereby the electronic components mounted on a surface of the substrate board are encapsulated with the resin, wherein a plurality of thin groove-shaped pots are provided in parallel at a predetermined pitch in a region, where the substrate board is disposed, of one of opposite surfaces of the lower mold and the upper mold, each thin groove-shaped pot is individually provided with a plurality of cavities in parallel through runners, a chase provided with plunger plates, which are inserted in advance into the thin groove-shaped pots so as to be able to move up and down, and the mold is slid sideways so as to be attachable to and detachable from the mold set, each plunger plate is driven by each plunger, the resin for encapsulation inserted into the pot is melted with the plunger plate, and the melted resin is filled in the cavities through the runners.
