    Abstract: A flexible substrate may have one or more bends. A bend in a flexible substrate may be made along a bend axis. Conductive traces in the flexible substrate may have elongated shapes. Each conductive trace may extend along a longitudinal axis that is perpendicular to the bend axis. Metal or other conductive materials may form the conductive traces. The traces may be formed from a chain of linked segments. Each segment may have patterned trace portions that surround one, two, or more than two openings. Traces may also be formed that have multiple layers of metal or other conductive material interconnected using vias. A polymer layer may cover the traces to align a neutral stress plane with the traces and to serve as a moisture barrier layer.

    Abstract: There is provided a security module for protecting circuit components from unauthorized access. The security module comprises a base printed circuit board, base PCB, for supporting circuit components to be protected, a frame printed circuit board, frame PCB, where the frame PCB is secured on top of the base PCB and defining a protective space for circuit components supported by the base PCB, and a lid printed circuit board, lid PCB, which is secured on top of the frame PCB, thereby providing a top closure to the protective space. First and third meshes are provided in the frame PCB, and a second mesh is provided in the lid PCB. The first, second and third meshes have a number of electrically conductive tracks, and one or more tamper detection paths are formed comprising a serial connection of one track from each of the first, second and third meshes. The security module may further comprise security circuitry arranged on the base PCB within the protective space, and for each tamper detection path the security circuitry has a pair of electrical signal input/outputs being electrically connected to the tamper detection path.

    Abstract: A main wire 111 has inner layer wiring patterns 161 to 165 which are wired on an inner layers 114 and 115 connected by via conductors 166 to 169 in series. In addition, a main wire 112 has inner layer wiring patterns 181 to 185 which are wired on the inner layers 114 and 115 connected by via conductors 186 to 189. The inner layer wiring patterns 161 to 165 and the inner layer wiring patterns 181 to 185 are wired so as to change the layer to the inner layer on the opposite side to each other. Branch wires 1211 to 1214 and 1221 to 1224 are branched from the via conductors 166 to 169 and 186 to 189, respectively. Thereby, the present invention provides an inexpensive printed wiring board which can reduce ringing without upsizing the printed wiring board.
