可编程逻辑 PCB Design Considerations and Guidelines for 0.4mm and 0.5mm WLPs

Abstract: Using a wafer-level package (WLP) can reduce the overall size and cost of your solution.However when using a WLP IC, the printed circuit board (PCB) layout can become more complex and, ifnot carefully planned, result in an unreliable design. This article presents some PCB designconsidera ...
