What is Stack-up? 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 des...
PCB Stackup对于电子设备的性能和可靠性起着至关重要的作用。正确的Stackup设计可以提供良好的信号完整性、电磁兼容性和热管理能力。另外,合理的Stackup设计还可以减少电磁干扰、信号串扰和噪声问题的发生。 3. PCB Stackup术语 3.1 板层(Layer) 在PCB Stackup中,每一层都被称为一个板层。通常,PCB Stackup包含...
PCB设计,即印刷电路板设计,涉及到一系列复杂的步骤和技术规范。以下是一些在PCB设计和制造过程中常常出现的词组和术语,了解它们将有助于更好地理解和参与PCB设计领域。 1. 层叠结构(Layer Stack-up) 指的是PCB内部不同层的布局和顺序,包括铜层、介电层(基材)、接地层和电源层的配置。 2. 导电路径(Conductor P...
打开工程文件V_induced.siw,通过主菜单Home→Layer Stackup Editor设置好PCB叠层数据,如图1-3 所示。 图1-3 叠层设置 2. 选择信号 通过菜单Tools选择Generate Ports on Nets,在图1-4 窗口选中信号网络,进行信号端口的自动建立。 3. 仿真设置 创建好端口之后,需要进行...
1.分层布局(Layer stackup):使用合适的分层布局,通常采用多层PCB,其中一些层用于信号引线和电源/地平面。分层布局可以有效地减少信号之间的干扰,并提供良好的电源/地参考平面。 2.地平面(Ground plane):确保足够大块的地平面,作为信号引线之间的隔离层,并提供良好的回流路径,以减少信号的干扰和噪音。
