WebFlip chip is a step in the direction of eliminating wire bonding. In the flip chip process, a die is connected face-down to a board or substrate using ball grid array (BGA) or other conductive bumps. This approach eliminates wire bonds, increases speeds and reduces size. Freescale’s RCP technology takes flip chip a step further by eliminating ... WebThe resulting completed flip chip assembly is much smaller than a traditional carrier-based system; the chip sits directly on the circuit board, and is much smaller than the carrier …

WebFlip Chip assemblies have several advantages over wire bonding. First, the flip chip enabled chip-scale packaging by eliminating the need for interconnection space surrounding the IC. This means that the entire package for your device can shrink to something roughly the scale of the IC, paving the way for more compact electronics. The flip chip ... WebStandard QFN packages use bond-wires to connect the silicon die to the leadframe. Bond-wires add parasitic resistance and inductance between the die and the leadframe. Many DC/DC converters are now being designed using the HR QFN package technology, which eliminates bond-wires and minimizes the parasitic resistance and inductance.
