Review:
Fan Out Wafer Level Packaging
overall review score: 4.2
⭐⭐⭐⭐⭐
score is between 0 and 5
Fan-out wafer-level packaging (FO-WLP) is an advanced packaging technology that involves redistributing the I/O connections of integrated circuits over a larger area at the wafer level, allowing for compact, high-performance, and cost-effective packages. It replaces traditional multi-chip modules and ball grid array (BGA) packages by enabling multiple chips to be embedded in a single wafer-level package with fan-out redistribution layers, leading to improved electrical performance and reduced form factors.
