高频印制电路板用铜箔选择Choosing Copper Foils for High Frequency PCBs铜箔在印制电路板的导体作用是显然的,但铜箔表面粗糙度会影响高频印制电路板电路信号传输。文章叙述了铜箔的种类,PCB用铜箔都有表面处理,铜箔表面粗糙度有不同规格,PCB的高频传输线电磁场分布与铜箔的关系,不同频率电信号传送时在
Choosing Copper Foils for High Frequency PCBs The role of copper foil on a printed circuit board is obvious, but the roughness of the copper foil can affect the signal transmission from the high frequency printed circuit board. The article describes the types of copper foil, PCB copper foil has surface treatment, copper foil surface roughness of different specifications, PCB high frequency transmission line electromagnetic field distribution and the relationship between copper foil, different frequency electrical signal transmission in
