    摘要: A method of making a pad array chip carrier package is disclosed. A semiconductor device (10) is bonded to a ceramic substrate (12). The semiconductor device may be attached to the substrate by wirebonding, tab bonding or flip chip bonding. The bonded assembly (16) is then attached to a flexible temporary support substrate (18) by means of an adhesive (19). The entire assembly is then placed into a mold cavity (20 and 22) and registered against the temporary support substrate (18). Plastic material (30) is molded about the semiconductor device and associated wirebonds in order to encapsulate the device. After removal from the mold, the encapsulated assembly is removed from the temporary support substrate (18) by peeling the temporary support substrate (18) from the circuit substrate.

    摘要: A grid array assembly method uses a flex circuitry substrate and includes providing a series of conforming flex circuitry substrates, the flex circuitry substrates include bonding pads and metallization on a first surface and, holes or vias in the substrate which define a contact pad array on the opposite surface. The substrates are tested and acceptable, then mounted on a carrier strip with longitudinally aligned apertures. The carrier strip is typically a metal such as copper. The strip with mounted substrates is then passed to a station where an IC die is mounted on the substrate first surface, wire bonds are placed from the die to the bonding pads, and the assembly is encapsulated by auto-molding to form a package body. Subsequently, interconnecting bumps are placed on the contact pads and the assembly is removed from the strip.

    摘要: An overmolded semiconductor package (150) is formed by electrically and mechanically attaching a semiconductor device (100) to a substrate (110) having at least one hole (130). A plastic molding compound (140) is overmolded around the semiconductor device 100) so as to encapsulate the device, the molding compound (140) extending at least partially into the substrate hole (130) to form an anchor (135) to aid in bonding the molding compound to the substrate. An alternate embodiment of the invention forms a pedestal (449) from the portion of the molding compound extending beyond the surface of the substrate. The pedestal functions as an anchor to aid in bonding the molding compound (440) to the substrate, and also as a spacer to maintain a preselected clearance between the substrate (410) and the printed circuit board (460). The portion of the molding compound extending beyond the surface of the substrate may also be used to form an alignment pin (548). The pin functions as an anchor to aid in bonding the molding compound to the substrate, and also as an alignment aid to maintain positional relationships between the substrate and the printed circuit board. In another embodiment of the invention, the overmolded semiconductor is mounted directly on a printed circuit board containing other active circuitry.
