Printed circuit board with good performance on impedance

摘要

A printed circuit board, comprises an insulative substrate, a grounding layer located on a surface of the insulative substrate and defining a through slot, a plurality of conductive pins located on an outer surface of the printed circuit board; and a fence layer located between the conductive path and the grounding layer. Each conductive pin defines at least a soldering portion. The soldering portion is alignment to the through slot along a vertical direction.
