免费下载 I【设计指南】在 Allegro X 中进行 HDI 设计:从叠层到签核的完整工作流程指南

随着 AI 服务器、高速通信、汽车电子等产品不断向更高算力和更小尺寸发展，PCB 设计正在面临越来越严苛的布线挑战。尤其是0.5mm、0.4mm甚至0.35mm间距 BGA 的大规模应用，使传统通孔设计越来越难满足布线密度需求，而 HDI（高密互连）技术已成为现代高速 PCB 设计的重要解决方案。

HDI 设计不仅仅是增加微孔那么简单，它涉及从叠层规划、过孔结构设计，到 BGA 扇出、可制造性验证以及 SI/PI 分析的完整设计流程。一个成功的 HDI 项目，往往从项目创建阶段就需要提前规划规则、叠层和过孔策略，而不是等到布线阶段再解决问题。

这本电子书将带你掌握什么？

01

HDI叠层与微孔规划

掌握 1-N-1、2-N-2 等主流 HDI 叠层结构设计方法，了解如何根据顺序压合工艺规划微孔、盲孔、埋孔和盘中孔结构。

02

BGA 扇出与高速布线

学习不同间距 BGA 的逃逸布线策略，以及如何利用微孔提升布线通道密度，在保证可制造性的同时实现高速信号走线。

03

DFM（Design For Manufacturing）

与可靠性验证

了解 HDI 设计中常见的树脂缺失、堆叠孔对位、铜密度失衡等制造风险，并掌握设计阶段提前规避问题的方法。

04

SI/PI 分析实践

学习如何利用 Sigrity X Aurora 对微孔结构、PDN阻抗、返回路径完整性等关键问题进行验证，从设计阶段降低高速风险。
