本研究是針對電子連接器內連之導線對電站的電性接觸作一改善，並試圖以一種電站對電站接觸的方式來取代傳統的導線對電站或彈簧對梢針的電性連接。以簡易的紡織技術的平紋織法來將銅合金線、PC纖維線及PET線作經緯的交織織製，具有高密度和設計靈活的特點、經緯交織的整齊排列性、加上以塑膠線與銅合金導線的高度彈性、簡易製造的技術和低成本等優點，相信可達到高導電率、高彈性強度、多微接觸點等多功能導電布。
由壓接荷重與接觸電阻的關係圖中可以分析得到此單向性導電布在壓接荷重約450~480gf(每一電站上8~9個接觸點所承受的荷重)時，能夠將其接觸電阻值穩定維持於20~22mΩ附近。當壓接荷重減少回復到250gf時仍維持著20~22mΩ的接觸電阻值，單向性導電布能將壓接於導電布的荷重能量儲存起來，在回復時藉由本身材質的回復彈性能保持低電阻，有別於一般的連接器在壓接時有連接的能力在回復時卻瞬間失去連接的能力。所以此導電布使用在導線對電站的中介層連接上，有儲存能量將接觸電阻的最低值(接觸時的最佳化)持續一段時間，來提昇連接器的可靠性。另外，在高頻傳輸下，本導電布也比傳統連接器有優越的電性表現。
本導電布的規格包括：(1)電接觸間距0.5mm，(2)接觸點密度約15~20/mm2，(3)電長度約0.4mm，(4)接觸電阻(Rc)~20mΩ，(5) 接觸正向力~60gf。

The objective of this study is to search for a new interconnecting method for connecting a conductive wire to a pad or a pad to a pad so as to repleace traditional design of a spring to a pin. The new interconnection material is made of a woven fabric which consists of a set of copper alloy wires and a set of insulating polymer wires both in one direction, and another set of insulating polymer wires in other direction orthogonal to the first set. It is believed to reach a high density of nobel design with a pattern of altitude-latitude grid orderly arranged reserving a high elastic property of both copper alloy wires and polymer wires. On top of these it is a relatively cost with high conductivity. It attains the ideal of Multi-Micro-Contact (MMC).
We have conducted a series of measuring the contact resistance (Rc) and the deformation (d) as a function of the compressive force (F). For the anisotropically conductive cloth. At a compressive force of about 450~480 gf loaded on the 8~9 spots per pad the contact resistance of between 20~22mΩ was attained and maintained. When the compressive force was recovered to about 250 gf the contact resistance of 20~22mΩ was still held.
The anisotropically conductive cloth was able to conserve the energy of compressive forces. Such an ability of preserving elastic energy in the conductive cloth is a new phenomenon form traditional connectors. In traditional connectors the normal force should disappear at the instant of unloading. So the connector reliability for the conductive cloth is expected to be high. Besides, at high frequency it should also perform better than the traditional connector.
The anisotropically conductive cloth we have studied include the following characteristics: (1) good for a contact pitch of about 0.5mm or less, (2) a high density of contact points of 15~20 points/mm2, (3) a short electrical length of about 0.4mm, (4) a low contact resistance as low 20mΩ per pad contact, (5) a low and stable contact force per contact pad of 60 gf.
