Abstract
Abstract In a printed circuit board assembly comprising vertical printed circuit boards, perpendicular printed circuit boards, which are perpendicular to the vertical printed circuit boards, are disposed horizontally. A vertical back-board module is used. A vertical front board is arranged parallel in front of the vertical back-board module and has a front surface and a back surface. A connector group attaches the vertical back-board module to the back surface. With vertical attaching and receiving connectors, the vertical printed circuit boards are attached perpendicularly to the vertical front board. Similarly, the perpendicular printed circuit boards are attached perpendicularly to the back board module with perpendicular attaching and receiving connectors.
