Abstract

VCCI had started Kit Module Program in 2005 in order to control EMI of the modules. In this program, the electric current on the power line (PL) of the power distribution network (PDN) on the printed circuit board (PCB) is measured by the magnetic probe (MP) method which has been standardized by IEC for the EMI testing of LSI. In this paper, the test result of several kinds of module is presented. They were tested by the measurement method of Kit Module Program and by the measurement method of the radiated emission (RE) complying with IEC/CISPR22. As the result, it was clarified that the MP method is suitable for the test of the module. Although the compatibility with the current EMI test method of VCCI exists as the problem, Kit Module Program will offer the simple and convenient management method to the manufacturers of the module and IT equipment (ITE).
