每次串行数据速率提高，其都会暴露出掩盖在低速下的问题。许多这些问题是因为PCB走线、过孔和连接器中发生损耗引起的信号完整性下降而造成的。虽然信号完整性问题的解决方案有很多，但每种方案都有其自身的缺点。解决这些问题的一种应对措施是使用 ...

PCB routing methods continue to evolve, and flexible routing techniques can reduce wire length and free up space on a PCB. Traditional PCB routing is limited by fixation of coordinates of wires and by ...

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 ...

When electronics engineers design PCBs, they must follow best practices for trace routing. This helps maintain PCB signal integrity and reduce electromagnetic interference (EMI). Crosstalk can occur ...

A common joke in electronics is that every piece of wire and PCB trace is an antenna, with the only difference being whether this was intentional or not. In practical terms, low-frequency wiring is ...

Recently, that number has risen to five, and while it adds far more flexibility for structuring electronic equipment, it also brings greater complexity and ratchets up the number of design decisions ...

印制电路板，简称 “PCB”，也叫印制线路板。它的主要作用，是通过电路连接各种电子元器组件，实现导通与传输，是电子产品里关键的电子互连件。几乎所有电子设备都得靠它，它既能为电子元器件提供固定装配的机械支撑，实现布线、电气连接或电绝缘，又 ...

Mentor Graphics Xpedition xPCB Layout has introduced new capabilities that will boost designers abilities to create even more complex PCB designs in less time and with greater accuracy than ever ...

My first experience with computerized printed-circuit-board (PCB) design was in 1978 when I acquired two Racal-Redac Mini systems for my service bureau, Computer Circuits. What memories remain from ...
