PROBLEM TO BE SOLVED: To suppress an electrostatic capacity of a through-hole of a high density/highly-multilayered printed-circuit board for transmitting a high-speed signal. SOLUTION: The through-hole for press fittig a press-fit pin is formed to the printed-circuit board of this invention. The printed-circuit board comprises at least one signal transmission layer, a wiring pattern for signal transmission formed to at least the one signal transmission layer, and an electrode part of the wiring pattern for signal transmission exposing on an inner circumferential surface of the through-hole. The electrode is formed not on the whole inner circumferential surface of the through-hole, but on only a part of it. COPYRIGHT: (C)2008,JPO&INPIT

Abstract:
An electrical connector assembly includes a circuit board and an electrical connector mounted on the circuit board. The circuit board has a circuit board body having first and second surfaces and through-holes bored between the first and second surfaces. The circuit board has signal traces on internal layers of the circuit board that are generally parallel to the first and second surfaces. Portions of the circuit board body within the through-holes are etched away to expose portions of the signal traces beyond the circuit board body within the corresponding through-hole. The electrical connector includes a housing and signal terminals held by the housing. The signal terminals are received in respective through-holes of the circuit board and engage the corresponding signal traces.
