  • Patent number: 8247272
    Abstract: A semiconductor package and a method for constructing the package are disclosed. The package includes a substrate and a die attached thereto. A first contact region is disposed on the substrate and a second contact region is disposed on the die. The first contact region, for example, comprises copper coated with an OSP material. A copper wire bond electrically couples the first and second contact regions. Wire bonding includes forming a ball bump on the first contact region having a flat top surface. Providing the flat top surface is achieved with a smoothing process. A ball bond is formed on the second contact region, followed by stitching the wire onto the flat top surface of the ball bump on the first contact region.

  • Publication number: 20100102436
    Abstract: A method of forming a device is disclosed. The method includes providing a printed circuit board substrate having a die attach region on a first surface of the substrate. The method also includes attaching a die to a die attach region. The die is electrically coupled to first land pads disposed on the first surface at the periphery of the die attach region. A cap is formed in a target area by a top gate process to produce a cap with an even surface. The cap covers the die and leaves at least the first land pads exposed.

  • Patent number: 6514845
    Abstract: The invention is a method for attaching an electronic component (40) having Ball Grid Array contacts (36) to a circuit board contact array (31) to prevent the solder balls (36) of the Ball Grid Array from fracturing and distorting during solder reflow when the Ball grid Array contact (36) is attached to a contact (31) on a printed circuit board (30) that has a via (32) extending at least partially though the printed circuit board (30). A solder form (35) is placed over each via (32) in each contact (31) of the contact array. The electronic component (40) that has BGA contacts (36) is placed over the contact array (31) such that each ball (36) of the ball grid array of the electronic component resides on a solder form (35). The component (40) and circuit board (30) is subjected to a solder reflow process to seal the component (40) to the circuit board (30). The solder form (35) at least partially fills the via (32) preventing the BGA contact (36) from collapsing into the via (32).
