Patent ID: 8258407

Claim:
A wiring board, comprising: a first wiring pattern including at least one mounting pad, the at least one mounting pad being configured for an electronic device to be mounted thereon, a second wiring pattern having lower impedance than the first wiring pattern, the second wiring pattern being separate and unconnected from the first wiring pattern, an ICT (in-circuit) wiring having a first end connected to the at least one mounting pad of the first wiring pattern and a distal end extending from the at least one mounting pad of the first wiring pattern, and at least one ICT pad formed at the distal end of the ICT wiring, the at least one ICT pad for measuring characteristic values of the electronic device mounted on the at least one mounting pad, wherein the ICT wiring extends towards the second wiring pattern so that the at least one ICT pad formed at the distal end of the ICT wiring is located in the vicinity of the second wiring pattern forming a discharge gap (G) between the at least one ICT pad and a corresponding ground land on the second wiring pattern to induce discharge between the at least one ICT pad and the second wiring pattern when static electricity above a predetermined value is applied to the first wiring pattern preventing application of the static electricity to the electronic device.
