WebAug 6, 2024 · For both chip sizes, in the application range of FOWLP (package/chip ratio = 3.24 and 4, respectively), the processing cost of FOWLP is lower than that of FC packaging. Figure 2: For chip size 5mm x 5mm, the FOWLP size is definitely <9mm x 9mm or a 3.24 package/chip ratio. This FOWLP cost less than a flip chip package.
WebThere are two approaches for FOWLP. Chips-first is a process whereby the chips are attached to a temporary carrier and molded to create a reconstituted wafer, which then has a buildup-layered structure deposited on the surface of the chips to create an RDL layer to interconnect the I/O pads on the chip to the ball grid array (BGA) pads. grapevine the venueFan-out wafer-level packaging (also known as wafer-level fan-out packaging, fan-out WLP, FOWL packaging, FO-WLP, FOWLP, etc.) is an integrated circuit packaging technology, and an enhancement of standard wafer-level packaging (WLP) solutions.
