WebJan 16, 2014 · Wafer-Level Chip-Scale Packaging (or “fan-in WLCSP”) and wafer processing for flip-chip. These new. facilities, half way between front-end foundries and regular assembly and packaging facilities, now. support high volume manufacturing on large size wafers, thus permitting economies of scale. Web1.2.1.3.1 Flip-chip devices. Flip-chip devices have solder bumps, other metal bumps, or even conductive adhesive bumps on the face of the device for I/O connections. During assembly, the devices are flipped face down, then mated and bonded to corresponding solder or metal pads on the package or interconnect substrate.
