PCB层叠设计经验总结 - 知乎 - 知乎专栏
PCB包含两个重要的组成部分： Core和PP（Prepreg，半固态片）。 Core的两个表面都铺有铜箔，用作导电层，两个表层之间填充以固态材料，其由增强材料玻璃纤维浸以 固态树脂 组成。 PP的表面没有铜箔，其由 半固态树脂 和玻璃纤维组成， 相比Core要软一些，其构成所谓的浸润层，在PCB中主要起填充作用，用以粘合芯板Core。 工厂生产时， 浸润层 一般无法做到超出3个PP（厚度大概在20mil左右）。 正由于PP的半固态特性，制作完成的各PCB中的PP厚度也会有所偏 …

2023年6月28日 · PCB stack-up is an important design and manufacturing aspect as it directly impacts the signal integrity of your design. Creating an efficient build-up mainly depends on selecting the right materials and optimum layer arrangement.
PCB叠层选择指南(PCB Stackup Selection Guideline) - 英特尔
请参考 PCB介电材料选择和高速通道布线上的纤维编织效应 获得更多信息。 为高速信号布线选择较小的介电高度。 它对跟踪阻抗目标要求更小的走线宽度。 在选择较宽的走线宽度和较短的走线宽度之间总是有权衡的。 较宽的宽度具有较少的趋肤深度和较低的插入损耗，但需要更多空间用于布线。 它还导致更小的PCB高度以及更小的跳变导通高度，以实现最小的阻抗失配。 对所有关键高速信号布线选择足够的带状线层 (stripline layer)。 Intel 建议对所有的关键高速信号 (15 …

Sierra Circuits’ PCB Stack-Up Design Guide provides guidelines for building an efficient stack-up with improved signal integrity, power distribution, and heat dissipation. A stack-up refers to the sequential arrangement of copper and dielectric layers in a PCB.
PCB Stackup Basics | Phil’s Lab | Industry Expert - Altium
2022年11月28日 · Before routing a PCB, we want to determine our stackup, which depends on the number of layers we have available. Then, we want to go through the layers one-by-one, assigning ground, power, or signals to individual layers. Combinations are of course also possible—we can mix power and ground, signal and ground or signal and power.
