Signal transmission structure of electrical connector and manufacturing method thereof

Abstract

A signal transmission structure and a manufacturing method thereof are disclosed. The signal transmission structure includes an insulation structure, least one electrically-conductive member, and a dielectric permittivity reduction micro structure. The insulation structure includes an insulation joining surface, wherein a material of the insulation structure has a first dielectric permittivity. The at least one electrically-conductive member is joined to the insulation structure, wherein a signal of high frequency is transmitted in the electrically-conductive member, and the electrically-conductive member has a conductor joining surface joined to the insulation joining surface. The dielectric permittivity reduction micro structure is formed on the conductor joining surface and sandwiched between the conductor joining surface and the insulation joining surface, wherein the dielectric permittivity reduction micro structure has a second dielectric permittivity; wherein the second dielectric permittivity is smaller than the first dielectric permittivity.
