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 designconsiderations and general recommendations for choosing a 0.4mm- or 0.5mm-pitch WLP for yourapplication.

(一) 布局设计原则 1. 距板边距离应大于5mm。 2. 先放置与结构关系密切的元件,如接插件、开关、电源插座等。 3. 优先摆放电路功能块的核心元件及体积较大的元器件,再以核心元件为 中心摆放周围电路元器件。 4. 功率大的元件摆放在利于散热的位置上,如采用风扇散热,放在空气的 主流通道上;若采用传导散热,应放在靠近机箱导槽的位置。 5. 质量较大的元器件应避免放在板的中心,应靠近板在机箱中的固定边放 置。
