휴대용 단말기 입력장치의(Wheel Key Module) ESD 내성강화 설계구현에 대한 연구

Recently, The portable terminal are grafted together as going various user selection functions by Trend change of small size slimness. It is risen to happened in ESD introspection quality Problem of Wheel Key Module that the small size slimness of Portable terminal was occurs to operation inability and damage of the IC device. Therefore, investigate about hardness design method that use FPCB Layout and ceramics capacitor.
