请按照以下指南对PCB布局中的高速信号进行正确的叠层选择: 选择选择具有最低损耗角正切和较小介电常数的介电材料,例如:Megtron6 (df<0.002, epsr=3.1)是一个合适的选择。 当它们在供应商表征后变得可用时,诸如Megtron 6N/6G或 Tachyan 100G的介电材料都是很好的选择。
1.2 PCB Stack-Up Principle After the number of circuit board layers determined, the following job is to reasonably arrange the placement order of the circuit of each layer. In this part, there are two main factors to be considered:
一、PCB 堆叠技术的概念 PCB 堆叠技术是指将多个 PCB 层通过特定的工艺堆叠在一起,形成一个整体的印刷电路板。这种技术可以大大提高 PCB 的密度,降低其厚度,从而满足电子产品日益小型化、轻型化的需求。 二、PCB 堆叠技术的分类 根据不同的堆叠方式和材料,PCB 堆叠技术可以分为以下几种: 1.软硬结合板:将柔性...
PCB Stack-Up PCB stack-up is an important factor in determining the EMC performance of a product. A good stack-up can be very effective in reducing radiation from the loops on the PCB (differential-mode emission), as well as the cables attached to the board (common-mode emission). On ...
But no matter the project, big or small, complex or trivial, creating a good stack-up definition can greatly improve long-term reliability and performance, reduce production costs, and allow for a smoother transition to manufacturing. Get your PCBs Built-Fast. Contact us for a PCB quote or ...
The article discusses "stack-up" in printed circuit board (PCB) analysis and design. The term "stack up" is referred to as the arrangement and the types of layer in a multilayer board. Designing a PCB stack-up is stated to involve ascertaining the number of signal layers needed to route...
Stack-up refers to the arrangement of copper layers and insulating layers that make up a PCB prior to board layout design. While a layer stack-up allows you to get more circuitry on a single board through the various PCB board layers, the structure of PCB stackup design confers many other...
