· 回到 PCB 文件(PcbDoc),搜索未知管脚所在的元件位号(快捷键 J 键 - C 键),检查元件封装是否有问题,可能是原理图中元件及其封装匹配错误,需要在原理图文件(SchDoc)中修改封装(属性(Properties)面板 - Footprint(封装))或重新绘制封装等,保证原理图库中的元件和封装中的元件管脚完全匹配; · 修改完成后,保存...
Summary In manufacturing multilayer printed circuit boards (PCBs), the PCB layer stack-up usually includes multiple plies of various types of prepreg along with the inner layer core material. Most of the layer stack-up process is manual operation relying on an operator to place the correct type ...
The PCB may include a set of layers perpendicular to the set of vias. The set of layers may include a signal layer and a ground layer. The ground layer may be located between the set of stub regions and the signal layer. The method may include drilling to remove at least a portion ...
