Wiring board and method of preventing high voltage damage
Abstract:
A wiring board is provided to protect an electronic device from static electricity and lightning surge without reducing packaging density. A wiring board is provided with a first wiring pattern (3) including mounting pads (8, 10), on which an electronic device (5) is mounted, a second wiring pattern (21) having lower impedance than the first wiring pattern (3), ICT wirings (13, 15) extending from the mounting pads (8, 10) of the first wiring pattern (3), and ICT pads (17, 19) formed at distal ends of the ICT wirings (13, 15). The ICT wirings (13, 15) extend towards the second wiring pattern (21) so that the ICT pads (13, 15) are in the vicinity of the second wiring pattern (21), and discharge gaps (G) are formed between the ICT pads (13, 15) and the second wiring pattern (21).
Abstract(Chinese):

提供了一种布线板，用于保护电子设备免受静电和雷电浪涌的影响，而不会降低包装密度。 布线板设置有第一布线图案（3），第一布线图案（3）包括安装有电子设备（5）的安装垫（8,10），具有比第一布线图案（3）低的阻抗的第二布线图案 ），从第一布线图案（3）的安装垫（8,10）延伸的ICT布线（13,15）以及形成在ICT布线（13,15）的远端处的ICT垫（17,19）。 ICT布线（13,15）朝向第二布线图案（21）延伸，使得ICT垫片（13,15）在第二布线图案（21）附近，并且排出间隙（G）形成在第二布线图案 ICT垫（13,15）和第二布线图案（21）。
