Fe3O4與導電材料之不同結構對雜訊抑制的影響

本研究探討Fe3O4與導電材料不同結構對於雜訊抑制的影響，討論Ploss/Pin對於0.1GHz~10GHz高頻雜訊抑制的影響。同時利用實作討論Fe3O4和導電材料不同結構來探討，Fe3O4粉末50wt%參雜ITK5517環氧樹脂50wt%，導電率為20S/m，厚度為0.03mm;導電材料為銀漿20wt%摻雜ITK5517環氧樹脂80wt%，其導電率為150 S/m，厚度為0.017mm，並利用HFSS模擬軟體模擬結果來佐證實作結果；其中主要影響為覆蓋結構不同，Ploss/Pin會有不同的結果表現。實驗發現，先將Fe3O4塗在MSL上，再塗上一層導電材料會比先只在MSL上塗Fe3O4效果來的好。

This study investigates the Fe3O4 and conductive material of different structures for the noise suppression. The effect of noise suppression in the frequency range beween 0.1~10GHz was investigated. The conductivity of 50wt% Fe3O4-50wt% epoxy with thickness of 0.03mm is 20 S/m ; and that of 20wt% Ag-80wt% epoxy with thickness of 0.017mm is 150S/m. The measured results are in agreement with the simulated results using HFSS simulator. Ploss / Pin is affected by the different structures of Fe3O4 and conductive materials. It is found that the noise suppression of Ag/Fe3O4/MSL is better than that of Fe3O4/MSL.
