Electrostatic interference prevention structure of circuit board

摘要

PROBLEM TO BE SOLVED: To provide a static electricity intrusion preventing structure of a circuit board capable of effectively preventing static electricity from intruding into a circuit pattern formed on the circuit board from the outside by a simple structure.;SOLUTION: In this static electricity intrusion preventing structure, electricity intrusion preventing patterns 83, 84, 85 for preventing static electricity from intruding into the circuit pattern 80 by grounding static electricity entering from the outside of the circuit pattern 80 are formed at a position surrounding the circuit pattern 80 of a circuit board 71, a position surrounding the circuit pattern 80 on a surface side earth board 72 mounted by being placed on the surface side of the circuit board 71, and a position surrounding the circuit pattern 80 on a back side earth board 73 mounted by being placed on the back side of the circuit board 71, respectively.;COPYRIGHT: (C)2007,JPO&INPIT
