PCB接線端子作為射頻連接器的一種，是電氣設備制造行業中的一個關鍵部件，起著不能取代、不容忽視的功效，因工程項目專業技術人員在維修時最 先也是以插口查驗，也就是說接線端子下手，因而接線端子排的設計方案至關重要。

商品的設計方案是集于：產品執行標準、原材料、構造、電鍍工藝、驗證、磨具(ju)、及生產制造加(jia)工(gong)工(gong)藝的一種綜合型設(she)計(ji)方案，接(jie)線(xian)端子也是如此。

（一）產品執行標準起著總體指導方針，基本上全部的考慮到都以它為根據，人們插拔式接線端子型號設計規(gui)范最 先以(yi)UL和CSA為標準，但(dan)是在一些(xie)電氣設備主要參數層(ceng)面還(huan)可以(yi)以(yi)別的(de)規(gui)范為根據(ju)，如高低溫試(shi)驗。

（二）原(yuan)(yuan)材(cai)(cai)料(liao)的(de)(de)(de)(de)(de)(de)(de)(de)(de)挑(tiao)(tiao)(tiao)選立即危害到(dao)全部商(shang)品的(de)(de)(de)(de)(de)(de)(de)(de)(de)特性(xing)(xing)，是(shi)設計(ji)方案的(de)(de)(de)(de)(de)(de)(de)(de)(de)重要，以(yi)塑料(liao)材(cai)(cai)料(liao)為例：假如要以(yi)UL94，V-0的(de)(de)(de)(de)(de)(de)(de)(de)(de)阻(zu)(zu)燃性(xing)(xing)為設計(ji)方案根(gen)據還(huan)要用(yong)心審(shen)批每家(jia)(jia)原(yuan)(yuan)材(cai)(cai)料(liao)物理性(xing)(xing)能表的(de)(de)(de)(de)(de)(de)(de)(de)(de)性(xing)(xing)能參數是(shi)不(bu)是(shi)能考慮(lv)商(shang)品的(de)(de)(de)(de)(de)(de)(de)(de)(de)規范，如沖擊(ji)性(xing)(xing)耐(nai)工(gong)作(zuo)電(dian)(dian)(dian)(dian)壓(ya)和抗(kang)老化實驗是(shi)不(bu)是(shi)能過，在(zai)五(wu)金(jin)(jin)材(cai)(cai)料(liao)層(ceng)(ceng)(ceng)(ceng)面(mian)(mian)關(guan)鍵是(shi)TP的(de)(de)(de)(de)(de)(de)(de)(de)(de)壓(ya)片糖果(guo)原(yuan)(yuan)材(cai)(cai)料(liao)挑(tiao)(tiao)(tiao)選特別是(shi)在(zai)關(guan)鍵，由于此壓(ya)片糖果(guo)不(bu)僅考慮(lv)一(yi)定的(de)(de)(de)(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)導率(lv)（電(dian)(dian)(dian)(dian)流量）又要有一(yi)定的(de)(de)(de)(de)(de)(de)(de)(de)(de)延(yan)展(zhan)性(xing)(xing)，在(zai)挑(tiao)(tiao)(tiao)選原(yuan)(yuan)材(cai)(cai)料(liao)層(ceng)(ceng)(ceng)(ceng)面(mian)(mian)讓(rang)我們的(de)(de)(de)(de)(de)(de)(de)(de)(de)技術工(gong)程(cheng)師產(chan)生(sheng)了艱難(nan)，而剛好再此層(ceng)(ceng)(ceng)(ceng)面(mian)(mian)更(geng)是(shi)射頻(pin)連(lian)接器生(sheng)產(chan)商(shang)在(zai)延(yan)展(zhan)性(xing)(xing)電(dian)(dian)(dian)(dian)子器件所追(zhui)求完美(mei)的(de)(de)(de)(de)(de)(de)(de)(de)(de)發(fa)展(zhan)趨勢，很多制造(zao)五(wu)金(jin)(jin)材(cai)(cai)料(liao)的(de)(de)(de)(de)(de)(de)(de)(de)(de)生(sheng)產(chan)廠家(jia)(jia)已(yi)經這些方面(mian)(mian)勤奮，電(dian)(dian)(dian)(dian)導率(lv)立即危害到(dao)溫度(du)和接觸(chu)(chu)電(dian)(dian)(dian)(dian)阻(zu)(zu)，延(yan)展(zhan)性(xing)(xing)的(de)(de)(de)(de)(de)(de)(de)(de)(de)優劣與(yu)原(yuan)(yuan)材(cai)(cai)料(liao)的(de)(de)(de)(de)(de)(de)(de)(de)(de)化學元素成分、彈性(xing)(xing)模具、強(qiang)度(du)、抗(kang)壓(ya)強(qiang)度(du)相關(guan)，彈性(xing)(xing)模具挑(tiao)(tiao)(tiao)選用(yong)材(cai)(cai)料(liao)力學的(de)(de)(de)(de)(de)(de)(de)(de)(de)第四強(qiang)度(du)理論公式計(ji)算(suan)開展(zhan)測算(suan)。原(yuan)(yuan)材(cai)(cai)料(liao)的(de)(de)(de)(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)導率(lv)越大接觸(chu)(chu)電(dian)(dian)(dian)(dian)阻(zu)(zu)就會(hui)越小溫升就會(hui)越低，插拔力與(yu)接觸(chu)(chu)電(dian)(dian)(dian)(dian)阻(zu)(zu)成二次曲線的(de)(de)(de)(de)(de)(de)(de)(de)(de)關(guan)聯(lian)，接觸(chu)(chu)電(dian)(dian)(dian)(dian)阻(zu)(zu)關(guan)鍵分：縮小電(dian)(dian)(dian)(dian)阻(zu)(zu)器、膜(mo)層(ceng)(ceng)(ceng)(ceng)電(dian)(dian)(dian)(dian)阻(zu)(zu)器、容積電(dian)(dian)(dian)(dian)阻(zu)(zu)器（電(dian)(dian)(dian)(dian)導體自身的(de)(de)(de)(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)阻(zu)(zu)器）。在(zai)其中膜(mo)層(ceng)(ceng)(ceng)(ceng)電(dian)(dian)(dian)(dian)阻(zu)(zu)器占總電(dian)(dian)(dian)(dian)阻(zu)(zu)器的(de)(de)(de)(de)(de)(de)(de)(de)(de)70~80%，都是(shi)危害射頻(pin)連(lian)接器使用(yong)壽(shou)命的(de)(de)(de)(de)(de)(de)(de)(de)(de)關(guan)鍵要素，應給(gei)與(yu)充(chong)足高(gao)度(du)重視，就以(yi)接線端子電(dian)(dian)(dian)(dian)鍍和渡銀來(lai)比，盡管(guan)銀的(de)(de)(de)(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)導率(lv)比金(jin)(jin)要高(gao)，可是(shi)其有機化學可靠性(xing)(xing)沒有金(jin)(jin)好，所造(zao)成的(de)(de)(de)(de)(de)(de)(de)(de)(de)膜(mo)層(ceng)(ceng)(ceng)(ceng)電(dian)(dian)(dian)(dian)阻(zu)(zu)器遠遠地超過電(dian)(dian)(dian)(dian)鍍，因此弄清左右相互關(guan)系針對人們挑(tiao)(tiao)(tiao)選原(yuan)(yuan)材(cai)(cai)料(liao)就會(hui)有指導作(zuo)用(yong)，是(shi)設計(ji)產(chan)品的(de)(de)(de)(de)(de)(de)(de)(de)(de)必要條件。
