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 ...
PCB layout 中走线和铺铜都尽量避免90 °直角 ,走45°或者圆弧角,特别是在高频信号传输线部分。 避免由传输线宽带来的反射和传输信号的失真。
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?这是老wu经常看见广大 PCB Layout ...

每个IC的电源端口附近都需要摆放去耦电容,且位置尽可能靠近IC的电源口,当一个芯片有多个电源口的时候,每个口都要布置去耦电容。 4、在PCB板边沿的元器件摆放方向与距离需要注意 由于一般都是用拼板来做PCB,因此在边沿附近的器件需要符合两个条件。
Layout设计中的几个关键步骤是布局、走线、铺铜、散热,英诺赛科高压单管GaN的Layout设计也不例外。 反激拓扑是高压单管GaN的典型应用,快充场合 ...
正因如此,在PCB设计过程中如何权衡利弊,找到合适的折衷方案,以减少这些干扰尽可能多地,甚至避免某些电路的干扰,是RF PCB设计成败的关键。 本文从PCB LAYOUT的角度,提供了一些处理技巧,对提高射频电路的抗干扰能力有很大的帮助。 1.RF布局 ...
Fundamental to careful system design of any DC/DC power converter is a well-planned and carefully executed printed circuit board (PCB) layout. An optimized layout leads to better performance, lower ...
A good layout design optimizes supply efficiency, alleviates thermal stress, and most importantly, minimizes the noise and interactions among traces and components. To achieve these, it is important ...
A printed circuit board turns separate parts into a stable system that powers up, talks to peripherals, and survives real ...
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.
When PCB layout tools were first introduced, they weren’t much better for routing traces than using an etch-a-sketch. Today, constraint-driven automation approaches have reduced the time required to ...
