摘要:
A cable connector assembly (100) used in high frequency signal transmission filed includes an insulative housing (2), a conductive terminals (3) retained in the housing, a number of wires (4) arrayed in a row and electrically connecting the terminals, and a conductive shell (5). The wires comprise at least one signal wire (40b) each comprising one or more conductive cores (401b) at the innermost thereof, and a grounding layer (403b) surrounding and shielding said core. The conductive shell comprises a base portion (510, 511, 520) shielding said housing and a soldering portion (521) integral with and behind said base portion. Each grounding layer abuts against and is soldered with said soldering portion of the shell, thereby simplifying grounding path.

A method for manufacturing printed circuit board includes steps below. An inner substrate including a first electrically conductive layer is provided. A first electrically conductive pattern is formed in the first electrically conductive layer. The first electrically conductive pattern includes an exposed region and an attaching region. A protective layer is formed on the entire exposed region. A first adhesive layer and a second electrically conductive layer are laminated on a surface of the first electrically conductive pattern in the attaching region and a surface of the protective layer. A slit along a boundary of the exposed region passing through the second electrically conductive pattern and the first adhesive layer is defined. The second electrically conductive layer corresponding to the exposed region, the first adhesive layer corresponding to the exposed region and the protective layer is removed.
