  • Publication number: 20100326704
    Abstract: A soldering pad layout for flexible printed circuit board (PCB) is disclosed, which comprises: a top substrate; a middle substrate; and a bottom substrate, being arranged by stacking one over the other successively in parallel. In an exemplary embodiment, there are at least a top routing layer, being sandwiched between the top substrate and the middle substrate, and at least a bottom routing layer, being sandwiched between the middle substrate and the bottom substrate. With the aforesaid soldering pad layout, not only circuit breakage caused by stress concentration on a bended flexible printed circuit board can be prevented, but also the routing path required on the PCB can be shortened and the amount of space for laying out parts on the PCB can be reduced.
