Abstract:
With the implementation of the YY0505-2012 standard of electromagnetic compatibility for medical devices industry,the issue of electromagnetic compatibility needs to be solved urgently. In order to analyze radiation EMI noise produced by complex medical electronic equipment,two theoretical models are proposed,including clock signal of chip crystal,flexible Printed Circuit(FPC)board. Furthermore,noise reduction methods are designed on the basis of the above radiated noised. The experiment results show that a microwave laser and urine monitor can pass the YY0505-2012 standard for medical devices industry by employing the suggested approaches of paper and that its noise decreased over 10 dBμV/m,so the validity of the approaches is verified.
