Flexible substrate and electronic device

A flexible substrate inserted in a hinge electrically connects circuit substrates, which are housed in a first casing and a second casing, respectively, to each other. The substrate has a power supply line and signal lines which are formed from a wiring conductor. Slits are opened in border portions of the power supply line in a cranked portion. The slits opened in the border portions of the power supply line make the rigidity of the border portions lower than in prior art. This means that a base is prevented from squashing the wiring conductor (power supply line) when the substrate is bent and that stress concentration on the border portions can accordingly be avoided. As a result, cracks in the border portions are prevented and the power supply line (wiring conductor) is protected against wire breakage.

Flexible wiring board and electrical device using the same

A flexible wiring board is obtained as follows. A copper foil pattern is formed on the both surfaces of a base polymer film made of polyimide, etc. The copper foil pattern of the both sides, except for an end portion of the copper foil pattern of one surface, is covered entirely with an insulative protecting film made of polyimide, etc., for protecting the copper foil pattern, and the insulative protecting film and the copper foil pattern are bonded with each other by an insulative protecting film adhesive layer. On the exposed end portion of the copper foil pattern on one surface is formed a plated layer to be connected to an electrical component. The thickness of the insulative protecting film which is bonded with the surface on which the plated layer is formed is set to be thinner than the base polymer film. As a result, it is ensured that insulation failure of the insulative protecting film is prevented, and wire breakage of wiring when bent can easily be prevented.

System and method for intelligent wire testing

A system and method for providing an intelligent wire testing capability for complex hardware systems. The system is comprised of a software application with a relational database interfacing with an automatic test equipment module. The relational database contains all of a system's architecture information plus all of the text and parametric information associated with the design. During a system test, the subject invention uses the wiring / system architecture as disclosed in the relational database together with an automatically generated test program to identify faults in a unit under test. Using the architecture knowledge, the subject invention is capable of automatically generating a wire harness schematic for printout or display on a CRT. The architecture knowledge also allows a technician to quickly distinguish between a broken wire and an unused pin in a connector. After the test, the observed values are stored in a testing results file for later review and trend analysis. Data from the trend analysis provides the technician with the data necessary to assess the state of the wiring in the UUT. At the completion of testing, the testing results file stays with the UUT thereby ensuring access to a complete testing history of the UUT at any time.
