Abstract: A heat dissipation apparatus for dissipating heat from two heat sources includes a heat sink, and a fan mounted on the heat sink. The heat sink includes a base and a plurality of parallel fins positioned on the base, the base contacts with one of the two heat sources for thermally conducting the heat generated by the one of the two heat sources. The fan is configured to generate airflow through the fins in such a manner that airflow flows from a second side of the fins to a first side of the fins. A deflecting member is mounted on the first side of the fins for deflecting airflow from the fan towards the second of the two heat sources.

Abstract: A circuit board assembly includes a circuit board and a semiconductor chip mounted on the board. The semiconductor chip includes a plurality of solder spots arrayed thereon in a matrix pattern. The solder spots except those located at corners of the pattern are jointed to the board via tin balls to form signal transmitting channels for transmitting signals between the board and the chip. Should the circuit board suffer impact, damage to the signal transmitting channels may be effectively minimized or prevented.

Abstract: A bump structure on a contact pad and a fabricating process thereof. The bump comprises an under-ball-metallurgy layer, a bonding mass and a welding lump. The under-ball-metallurgy layer is formed over the contact pad and the bonding mass is formed over the under-ball-metallurgy layer by conducting a pressure bonding process. The bonding mass having a thickness between 4 to 10 μm is made from a material such as copper. The welding lump is formed over the bonding mass such that a sidewall of the bonding mass is also enclosed.

Abstract: An under-ball-metallurgy layer between a bonding pad on a chip and a solder bump made with tin-based material is provided. The under-ball-metallurgy layer at least includes an adhesion layer over the bonding pad, a nickel-vanadium layer over the adhesion layer, a wettable layer over the nickel-vanadium layer and a barrier layer over the wettable layer. The barrier layer prevents the penetration of nickel atoms from the nickel-vanadium layer and reacts with tin within the solder bump to form inter-metallic compound. This invention also provides an alternative under-ball-metallurgy layer that at least includes an adhesion layer over the bonding pad, a wettable layer over the adhesion layer and a nickel-vanadium layer over the wettable layer. The nickel within the nickel-vanadium layer may react with tin within the solder bump to form an inter-metallic compound.
