Abstract :
This paper describes PCB Layout for EMI (Electromagnetic Interference) design of grounding and connector relation, it will be reduced design cost and get a lower EMI emission and get passive ESD testing report, the theory is following EMI EN55022, EN55024 and EN60950 requirement to implement on testing result, it will be designed to high-frequency PCB for EMI concern. This provide also discuss an efficient and systematic technique for modeling pairs signal and finding EMI filter of differential signal. This analysis do correlation to demonstrate the validly of our signal model, than apply the simulation technique to find appropriate EMI filter for a physical circuit. This paper also provides troubleshooting between handheld system connector and grounding problems.
