  • Publication number: 20070045863
    Abstract: A packaging process including the following steps is provided. First, a first substrate and a second substrate are provided. The first substrate has first contacts, and the second substrate has second contacts. Next, the first substrate is placed on the second substrate, such that the first contacts are aligned with the second contacts.

  • Publication number: 20060229111
    Abstract: An input device has a body and a battery that is retained in the body. A receiver is coupled to a computer via a cable, with the body removably engaging the receiver. The computer delivers power through the cable and the receiver to charge the battery, while the input device simultaneously transmits operational signals to the receiver for further transmission to the computer.

  • Patent number: 6856507
    Abstract: In a personal digital assistant assembly, a coupling block disposed on an operating surface of a base module is rotatable about a pivot axle transverse to the operating surface. An elongated hinge unit interconnects pivotally a connecting end of a personal digital assistant and the coupling block such that the personal digital assistant is rotatable about a longitudinal axis parallel to the operating surface and transverse to the pivot axle and is movable to a desired angular position relative to the coupling block. The coupling block is movable between an expanded position, where the personal digital assistant uncovers a user input unit on the operating surface of the base module, and a closed position, where the personal digital assistant is capable of covering the user input unit.

  • Patent number: 6342443
    Abstract: A packaging process providing a die with C4 solder bumps and a polymer substrate first. It then jets the melted second solder onto each of the C4 solder bumps forming a second solder bump. After reflowing and leveling the solder bumps, the die is flipped and combined with the substrate. Then heat treatment proceeds with the combination of the die and the substrate forming a flip chip package with collapse-controlled solder bump on the polymer substrate.

  • Patent number: 6153939
    Abstract: A flip-chip semiconductor device and a method for under filling the flip-chip semiconductor device are disclosed. The flip-chip semiconductor device is provided with a substrate and a die having a plurality of solder bumps for connecting to the substrate. Encapsulation material is under filled between the die and the substrate. The substrate has a non-mask area defied in a center portion thereof while the remaining surface area is covered by a solder mask. The non-mask area defines a hole in the center thereof so that the encapsulation material can be dispensed along all sides of the die to flow toward the non-mask area and stop when reaching the non-mask area whereby the encapsulation material does not block the hole and air between said die and the substrate is limited in a void formed around the hole and communicated with the atmosphere via the hole.
