於3C產業中,傳輸線纜可作為兩個電子裝置之間電性連接的媒介且可穩定的進行所預期的訊號傳輸作業,藉此,傳輸線纜普遍地應用於各種電子裝置。其中與USB、HDMI、DVI、Displayport等介面連接的傳輸線纜具有傳輸速率高、距離遠、品質高而受大眾喜愛,使用數量也日益增加。該等傳輸線纜內部具有多條金屬導線,包括有差分訊號線和接地線等。該多條金屬導線通常僅靠外側的麥拉層與金屬層進行固定,固定後會於金屬層和導線之間存在空氣,進而影響導線的高頻傳輸性能。另,隨著電腦技術的發展,電腦硬碟及主機板等電子產品資料傳輸的速度愈來愈快,傳輸頻率也愈來愈高,於高頻、超高頻資料傳輸領域,控制差分訊號線之差分阻抗對高速數位訊號的完整性係非常重要的,習知導線設置已無法滿足要求。In the 3C industry, the transmission cable can be used as a medium for electrical connection between two electronic devices and can stably perform the expected signal transmission operation.
