WebFlip Chip Bonding Work Flow Conductive Bumps Alignment Reflow Encapsulation Curing Conductive Bumps The first step is to deposit electrically conductive bumps on the surface of the bond pads of a die. Electrically conductive bumps can be deposited on the die using many different process and material combinations. WebFlipChip Assembly Process . During the final processing step of the wafer bumping, the bumps are placed on the pads of the chip which can be found on the wafer’s top side. . In order for the chip to be connected or …
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. WebFlip Chip Processes Flip chip technology is often equated with solder bumping, but there are many other flip chip processes, including the use of adhesives to make the mechanical and electrical connection. Adhesive processes include the use of anisotropic conductive adhesives, conductive adhesive polymers and non-conductive adhesive materials.
