backdrilling becomes challenging for denser vias, such as the via field underneath a central processing unit (CPU) and chipset package, or the stub length becomes longer on a thick board. Backdrilling cannot completely remove the stubs because of the drill depth tolerance ...
ViaStubVia本身有电容(Capacitive)及电感(Inductive)效应.倘若用PATH(PlatedThrough-Hole)贯串性Via会产生stub(残端)效应,产生反射波 2022-09-22 17:35:24 【转】PCB中Via与Pad什么区别 Pcb设计文件Via与Pad什么区别via称过孔,有通孔、盲孔和埋孔之分,主要用于网络在不同层的导线的连接,不可作为插件孔焊接元件。
A method for removing via stub comprises the following steps: plating copper on the wall of the via routed on the upper layer of the PCB other than that on the lower layer; engaging the upper layer and the lower layer of the PCB through a connection layer; removing the via stub on the...
