METHOD FOR MOUNTING COMMON MODE CHOKE COIL AND STRUCTURE FOR MOUNTING COMMON MODE CHOKE COIL

摘要

PROBLEM TO BE SOLVED: To provide a method for mounting a common mode choke coil with sufficient noise suppression effect in consideration of a common mode current leaking from a common mode choke coil and a structure for mounting the common mode choke coil.;SOLUTION: The method for mounting the common mode choke coil comprises a common mode choke coil positioning process S1 and a common mode choke coil connecting process S2. The positioning process S1 determines a position P for disposing the common mode choke coil 1 on a substrate 100. Concretely, after the first process is performed, a simulation determines the position P where a common mode current leaking from the common mode choke coil 1 and a common mode current reflected by a connector 120 mutually cancel or weaken. The connecting process S2 actually forms lands 21-24 in the position P of the common mode choke coil 1, and connects the common mode choke coil 1 therewith.;COPYRIGHT: (C)2012,JPO&INPIT
