现在但凡打开SoC原厂的PCB Layout Guide，都会提及到高速信号的走线的拐角角度问题，都会说高速信号不要以直角走线，要以45度角走线，并且会说走圆弧会比45度拐角更好。 事实是不是这样？PCB走线角度该怎样设置，是走45度好还是走圆弧好？90度直角走线到底行不行 ...

在电子电路系统中，印刷电路板（PCB）是承载电子元器件、实现电气连接的关键载体，而PCB Layout（印制电路板布局布线）设计则是决定PCB性能优劣的核心环节。从电子产品的信号完整性到电磁兼容性，从产品的可靠性到生产成本，PCB Layout设计的质量都起着决定 ...

Despite increasing levels of semiconductor integration and readily available systems-on-chips for many applications, in addition to the increasing availability of highly-featured development boards, ...

This is the first of several articles in the PCB Design Best Practices series, which discusses the different steps of PCB development from the basics of creating a design schematic with specific ...

在DCDC电源电路中，PCB的布局对电路功能的实现和良好的各项指标来说都十分重要。本文以buck电路为例，简单分析一下如何进行合理PCB layout布局以及设计中的注意事项。如有问题，欢迎指正。 首先，以最简单的BUCK电路拓扑为例，下图（1-a）和（1-b）中分别标明 ...

Moore’s law, applied to data rates, has pushed PCB circuits so fast that the layout becomes part of the circuit. In designs such as DDR3 and PCIe, the fastest memory and high-speed serial performance ...

It is a good day for design review! Today’s board is the MuBook, a Lattepanda Mu SoM (System-on-Module) carrier from [LtBrain], optimized for a NAS with 4 SATA and 2 NVMe ports. It is cheap to ...

Today’s PCB design review is a board is from [Wificable]. iI’s a novel dual-SSD laptop adapter board! See, CPUs and chipsets often let you split wide PCIe links into multiple smaller width links. This ...
