  • Patent number: 8574967
    Abstract: An improved semiconductor device package is manufactured by attaching semiconductor chips (130) on an insulating substrate (101) having contact pads (103). A mold is provided, which has a top portion (210) with metal protrusions (202) at locations matching the pad locations. The protrusions are shaped as truncated cones. The substrate and the chips are loaded onto the bottom mold portion (310); the mold is closed by clamping the top portion onto the bottom portion so that the protrusions approach the contact pads. Encapsulation compound is introduced into the cavity and the protrusions create apertures through the encapsulation compound towards the pad locations.

    Abstract: When a resin sealed package is molded with use of a release film for the purpose of preventing generation of a flash on a surface of a seal glass, the seal glass may be broken by being compressed and bent by the release film at a portion of the seal glass below which there is a cavity. The present invention prevents this breakage of the seal glass. More specifically, the present invention prevents breakage of the seal glass by forming a recess corresponding to a compression allowance of the release film at a mold die above the portion of the seal glass below which there is the cavity, or at the seal glass itself, and thereby releasing a pressure from the release film.

  • Publication number: 20110261550
    Abstract: A conductive paint electromagnetic interference (EMI) shield for an electronic module or device. The conductive paint is composed of metal particles suspended in a fluidic carrier. In one embodiment, the conductive paint is sprayed onto exterior surfaces of an electronic module or device from a spray gun. The sprayed conductive paint is cured to remove the fluidic carrier, leaving a metal film coated to the outside of the module or device. In one embodiment used with electronic packages in array form, grooves are cut into an encapsulation material of a module so that the shield protection includes sidewalls of the package. In another embodiment used with camera modules, masking is used to selectively shield portions of the module. In a further embodiment, the shield is electrically connected to a ground conductor of a circuit of the electronic module.

  • Patent number: 8003036
    Abstract: There are provided a mold for forming a molding member and a method for forming a molding member using the same. The mold includes an upper surface, and a lower surface having an outer peripheral surface and a concave surface surrounded by the outer circumference. Injection and discharge holes extend from the upper surface to the lower surface. Accordingly, after the mold and the package are coupled so that the discharge hole is directed upward, a molding member can be formed on the package by injecting the molding material through the injection hole, whereby it is possible to prevent air bubbles from being captured in the molding member.

  • Publication number: 20110115125
    Abstract: A method for encapsulating a substrate includes placing a hardened encapsulant material in a container. The encapsulant material is then heated and stirred until it is in a liquid or gel state. The liquid encapsulant material is held in the container in a vacuum state and dispensed over semiconductor dies along a guide, which allows the liquid encapsulant material to cool slightly before it covers a die.

  • Patent number: 7943072
    Abstract: A resin molded article (1) is formed such that a primary molded article (10), collars (40) and a metal flat plate (50) are molded integrally as inserts in a secondary molded portion (30). A rib (12) extends in a longitudinal direction along a surface of the primary molded article (10) that is adjacent to a surface facing a gate (62), but not a terminal surface (13). Supports (61) are provided intermittently along the longitudinal direction on a cavity inner surface (63) of a molding die (60) for supporting the rib (12). The primary molded article (10) is reinforced by the rib (12), and is not likely to be deformed by resin injected from the gate (62) and is not likely to be displaced.
