PCB Layout 跳坑指南——PCB走线角度选择到底该不该90°？

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 ...

PCB走线角度为90度到底行不行？

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 ...

Motor-Driver PCB Layout Guidelines (Part 1)

Printed-circuit-board (PCB) substrate material, like FR-4 glass epoxy, is a poor conductor of heat. Conversely, copper is an excellent conductor of heat. So, more copper area on a PCB is ideal from a ...
