Alink shielding can

In the past 10 years,electronical technology getting faster for the function and outlook design so as to attract

the market and lead the market.

In that reason,EMI problem is getting complicated due to high frequency and tiny size ,which will bother the

designer and let the project slow down or even stop going.

In general, EMI solution come from the shielding function,like fabric over foam,conductive fabric,copper / Al foil

....etc,which will give over 90% efficiency of EMI solution in EMI problem,but shielding function is not the only

solution for EMI but absorbing function also the another solution especially shielding solution is applicated and

there is still something problem in EMI issue.

Alink Precision Co.,Ltd. have introduced a absorbing material for EMI solution and will give our client another

selection when EMI is happening.

電磁波吸收原理：

電磁波吸收體依其吸收材料之損失機構可分為導電損失,介電損失及磁性損失三種類型,任何電磁波吸收體皆可用一般阻抗

(Impedance)整合型電磁波吸收來設計,阻抗整合型電磁波吸收即是阻抗匹配電磁波吸收原理,以此來解釋吸收之原理機構.
電磁波吸收體後方緊貼有一金屬板，當入射的電磁波穿透電磁波吸收體後碰到金屬板反射回來，藉控制吸收體內材料的

電磁特性，讓電磁波有適當的振幅與相位在吸收體內多重反射，使得電磁波在吸收體內有多重吸收，而電磁波總反射量

減少，達到電磁波吸收效率之提昇，吸收體之吸收率亦即是反射損失之總合除以入射波。
