PCB的(de)(de)插(cha)接(jie)(jie)件連(lian)(lian)(lian)接(jie)(jie)方(fang)(fang)式(shi)：1、標準插(cha)針(zhen)(zhen)連(lian)(lian)(lian)接(jie)(jie)：此(ci)方(fang)(fang)式(shi)可以(yi)用(yong)于(yu)PCB的(de)(de)對外(wai)連(lian)(lian)(lian)接(jie)(jie)，尤(you)其在小型儀器(qi)中(zhong)常采用(yong)插(cha)針(zhen)(zhen)連(lian)(lian)(lian)接(jie)(jie)。通過標準插(cha)針(zhen)(zhen)將兩塊(kuai)(kuai)PCB連(lian)(lian)(lian)接(jie)(jie)，兩塊(kuai)(kuai)PCB一般平(ping)行(xing)或(huo)垂直，容易實(shi)現批量生產(chan)。2、PCB插(cha)座(zuo)：此(ci)方(fang)(fang)式(shi)是從PCB邊緣做出(chu)印制(zhi)插(cha)頭(tou)，插(cha)頭(tou)部分(fen)按照插(cha)座(zuo)的(de)(de)尺寸、接(jie)(jie)點(dian)(dian)數、接(jie)(jie)點(dian)(dian)距離、定位孔的(de)(de)位置等進行(xing)設計(ji)，使其與專門用(yong)PCB插(cha)座(zuo)相配。在制(zhi)板時(shi)，插(cha)頭(tou)部分(fen)需要(yao)鍍金處理(li)，提(ti)高耐磨性(xing)能，減少接(jie)(jie)觸電(dian)阻。這種(zhong)方(fang)(fang)式(shi)裝(zhuang)配簡(jian)單(dan)，互(hu)換(huan)性(xing)、維修性(xing)能良好，適用(yong)于(yu)標準化大批量生產(chan)。其缺點(dian)(dian)是PCB造價提(ti)高，對PCB制(zhi)造精度及工藝要(yao)求較(jiao)高；可靠性(xing)稍差，常因插(cha)頭(tou)部分(fen)被氧化或(huo)插(cha)座(zuo)簧片(pian)老化而接(jie)(jie)觸不良。為了(le)提(ti)高對外(wai)連(lian)(lian)(lian)接(jie)(jie)的(de)(de)可靠性(xing)，常把同(tong)一條引出(chu)線通過線路(lu)板上同(tong)側(ce)或(huo)兩側(ce)的(de)(de)接(jie)(jie)點(dian)(dian)并聯引出(chu)。PCB插(cha)座(zuo)連(lian)(lian)(lian)接(jie)(jie)方(fang)(fang)式(shi)常用(yong)于(yu)多板結構的(de)(de)產(chan)品(pin)，插(cha)座(zuo)與PCB或(huo)底(di)板有簧片(pian)式(shi)和插(cha)針(zhen)(zhen)式(shi)兩種(zhong)。湖南電(dian)子PCB廠家印制(zhi)線路(lu)板由絕(jue)緣底(di)板、連(lian)(lian)(lian)接(jie)(jie)導線和裝(zhuang)配焊接(jie)(jie)電(dian)子元件的(de)(de)焊盤組(zu)成。

根(gen)據電路(lu)(lu)(lu)(lu)層(ceng)(ceng)(ceng)數分類(lei)：分為(wei)單面(mian)(mian)(mian)(mian)(mian)板(ban)(ban)、雙(shuang)(shuang)(shuang)(shuang)面(mian)(mian)(mian)(mian)(mian)板(ban)(ban)和多(duo)層(ceng)(ceng)(ceng)板(ban)(ban)。常(chang)見的(de)(de)(de)多(duo)層(ceng)(ceng)(ceng)板(ban)(ban)一(yi)(yi)般為(wei)4層(ceng)(ceng)(ceng)板(ban)(ban)或(huo)6層(ceng)(ceng)(ceng)板(ban)(ban)，復雜(za)的(de)(de)(de)多(duo)層(ceng)(ceng)(ceng)板(ban)(ban)可達幾十層(ceng)(ceng)(ceng)。單面(mian)(mian)(mian)(mian)(mian)板(ban)(ban)（Single-SidedBoards）在(zai)(zai)較基本的(de)(de)(de)PCB上(shang)(shang)，零件集中(zhong)(zhong)(zhong)在(zai)(zai)其(qi)中(zhong)(zhong)(zhong)一(yi)(yi)面(mian)(mian)(mian)(mian)(mian)，導(dao)線(xian)則集中(zhong)(zhong)(zhong)在(zai)(zai)另(ling)一(yi)(yi)面(mian)(mian)(mian)(mian)(mian)上(shang)(shang)（有(you)貼片元件時和導(dao)線(xian)為(wei)同一(yi)(yi)面(mian)(mian)(mian)(mian)(mian)，插件器(qi)件在(zai)(zai)另(ling)一(yi)(yi)面(mian)(mian)(mian)(mian)(mian)）。因(yin)為(wei)導(dao)線(xian)只出(chu)現在(zai)(zai)其(qi)中(zhong)(zhong)(zhong)一(yi)(yi)面(mian)(mian)(mian)(mian)(mian)，所以這種PCB叫作單面(mian)(mian)(mian)(mian)(mian)板(ban)(ban)（Single-sided）。因(yin)為(wei)單面(mian)(mian)(mian)(mian)(mian)板(ban)(ban)在(zai)(zai)設計(ji)線(xian)路(lu)(lu)(lu)(lu)上(shang)(shang)有(you)許多(duo)嚴格的(de)(de)(de)限制（因(yin)為(wei)只有(you)一(yi)(yi)面(mian)(mian)(mian)(mian)(mian)，布線(xian)間不能交叉而必須繞獨自的(de)(de)(de)路(lu)(lu)(lu)(lu)徑），所以只有(you)早期(qi)的(de)(de)(de)電路(lu)(lu)(lu)(lu)才使用這類(lei)的(de)(de)(de)板(ban)(ban)子。雙(shuang)(shuang)(shuang)(shuang)面(mian)(mian)(mian)(mian)(mian)板(ban)(ban)（Double-SidedBoards）這種電路(lu)(lu)(lu)(lu)板(ban)(ban)的(de)(de)(de)兩(liang)面(mian)(mian)(mian)(mian)(mian)都有(you)布線(xian)，不過(guo)要(yao)用上(shang)(shang)兩(liang)面(mian)(mian)(mian)(mian)(mian)的(de)(de)(de)導(dao)線(xian)，必須要(yao)在(zai)(zai)兩(liang)面(mian)(mian)(mian)(mian)(mian)間有(you)適當的(de)(de)(de)電路(lu)(lu)(lu)(lu)連接才行。這種電路(lu)(lu)(lu)(lu)間的(de)(de)(de)“橋梁”叫做導(dao)孔(kong)（via）。導(dao)孔(kong)是在(zai)(zai)PCB上(shang)(shang)，充滿或(huo)涂上(shang)(shang)金屬的(de)(de)(de)小洞(dong)，它可以與兩(liang)面(mian)(mian)(mian)(mian)(mian)的(de)(de)(de)導(dao)線(xian)相(xiang)連接。因(yin)為(wei)雙(shuang)(shuang)(shuang)(shuang)面(mian)(mian)(mian)(mian)(mian)板(ban)(ban)的(de)(de)(de)面(mian)(mian)(mian)(mian)(mian)積比單面(mian)(mian)(mian)(mian)(mian)板(ban)(ban)大了(le)一(yi)(yi)倍，雙(shuang)(shuang)(shuang)(shuang)面(mian)(mian)(mian)(mian)(mian)板(ban)(ban)解決了(le)單面(mian)(mian)(mian)(mian)(mian)板(ban)(ban)中(zhong)(zhong)(zhong)因(yin)為(wei)布線(xian)交錯的(de)(de)(de)難點(dian)（可以通(tong)過(guo)孔(kong)導(dao)通(tong)到另(ling)一(yi)(yi)面(mian)(mian)(mian)(mian)(mian)），它更(geng)適合用在(zai)(zai)比單面(mian)(mian)(mian)(mian)(mian)板(ban)(ban)更(geng)復雜(za)的(de)(de)(de)電路(lu)(lu)(lu)(lu)上(shang)(shang)。

隨著電(dian)氣時(shi)代的發展，人(ren)類生活環境中各種電(dian)磁(ci)(ci)波源越來(lai)越多，例如無(wu)線(xian)電(dian)廣播、電(dian)視、微波通(tong)信、家庭(ting)用的電(dian)器(qi)、輸(shu)電(dian)線(xian)路(lu)的工頻(pin)(pin)電(dian)磁(ci)(ci)場(chang)、高頻(pin)(pin)電(dian)磁(ci)(ci)場(chang)等。 當(dang)這些電(dian)磁(ci)(ci)場(chang)的場(chang)強(qiang)超過(guo)一定限度、作(zuo)用時(shi)間足(zu)夠長時(shi)，就(jiu)可(ke)能(neng)危及人(ren)體健康；同時(shi)還(huan)會干(gan)擾其他電(dian)子(zi)(zi)設備和通(tong)信。對此，都需(xu)要(yao)進行防(fang)護。對電(dian)子(zi)(zi)產品(pin)開發，生產、使用過(guo)程(cheng)中常(chang)常(chang)提(ti)出電(dian)磁(ci)(ci)干(gan)擾、屏(ping)蔽(bi)等概(gai)念。電(dian)子(zi)(zi)產品(pin)正常(chang)運行時(shi)其中心是PCB板及其安(an)裝在(zai)上面的元器(qi)件(jian)(jian)、零(ling)部件(jian)(jian)等之間的一個協調工作(zuo)過(guo)程(cheng)。要(yao)提(ti)高電(dian)子(zi)(zi)產品(pin)的性能(neng)指(zhi)標(biao)減少電(dian)磁(ci)(ci)干(gan)擾的影響(xiang)是非(fei)常(chang)重(zhong)要(yao)的。通(tong)常(chang)，由于(yu)基材有限的抗熱性，柔性印(yin)制電(dian)路(lu)中的焊接就(jiu)顯得(de)更為重(zhong)要(yao)。
