PCB design guidelines are created as benchmarks for circuit design engineers to meet the industry standards. Following these guidelines will ensure better manufacturability and robust product ...

There are certain design guidelines for PCBs that don’t make a lot of sense, and practices that seem excessive and unnecessary. Often these are motivated by the black magic that is RF transmission.

This application note focuses on printed circuit board (PCB) layout considerations for QFN and DQFN packages. This is intended for users who are familiar with PCB design, as well as, signal integrity ...

我们经常在教科书或者原厂的PCB Design Guide里看到一些关于高频高速信号的设计原则，其中就包括在PCB电路板的边缘不要走高速信号线，而对于板载PCB天线的设计来说，又建议天线要尽量靠近板边放置。这是什么科学道理？ 我们在初中阶段就已经知道，安培右手 ...

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 ...

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°角走线，并且会说走圆弧会比45°拐角更好。 事实是不是这样？PCB走线角度该怎样设置，是走45°好还是走圆弧好？90°直角走线到底行不行？

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。 大家开始纠结于pcb走线的拐角角度，也就是近十几二十年的事情。上世纪九十年代初，PC界 ...
