Since it is fabricated as a single entity, any type of board, including a rigid-flex board, must be designed as a single entity. In printed circuit board design, the layer stack defines how the layers are arranged in the vertical direction, or Z plane. By joining rigid sections of PCB together via flexible sections, complex, hybrid PCBs can be designed that can be folded to fit into unusually shaped enclosures. Technological innovation and refinements in the processing technology have led to a number of revolutionary concepts in PCB fabrication, including the ability to design and manufacture flexible PCBs. On the right is a rigid-flex PCB, where rigid sections are connected via flexible sections of PCB.įast forward to today, where almost all PCB designs have multiple copper layers. Connections are formed in the copper layer(s) as conductive traces by etching away (removing) unwanted copper.Ī single-sided PCB is shown on the left, typical of early PCB design. In the early days of printed circuit board (PCB) manufacturing, the board was simply an insulating core layer, clad with a thin layer of copper on one or both sides.

The PCB is designed and formed as a stack of layers. High Quality, Flexible Design Documentation.
