單面板就是在最基本的PCB上，零件集中在其中一面，導線則集中在另一面上。因為導線只出現在其中一面，所以我們就稱這種PCB叫作單面板(Single-sided)。因為單面板在設計線路上有許多嚴格的限制(因為只有一面，布線間不能交叉而必須繞獨自的路徑)，所以只有早期的電路才使用這類的板子。

　　PCB單面板與雙面板有的區別

　　單面(mian)板的布(bu)線圖以網路印(yin)刷(Screen Printing)為主，亦即在(zai)銅表面(mian)印(yin)上(shang)(shang)阻(zu)劑(ji)，經蝕刻后(hou)(hou)再以防焊阻(zu)印(yin)上(shang)(shang)記號，最后(hou)(hou)再以沖孔加工(gong)方(fang)式完(wan)成零件導孔及外(wai)形。此外(wai)，部份少量(liang)多(duo)樣(yang)生產(chan)的產(chan)品，則采用感光(guang)阻(zu)劑(ji)形成圖樣(yang)的照(zhao)相法。

　　雙面板(Double-Sided Boards)的兩面都有布(bu)線(xian)。不過要(yao)用上兩面的導(dao)線(xian)，必須要(yao)在兩面間有適當的電路連接(jie)才行。這種電路間的「橋梁」叫做導(dao)孔(via)。導(dao)孔是在PCB上，充滿或涂上金屬的小洞，它(ta)(ta)可(ke)以(yi)與(yu)兩面的導(dao)線(xian)相(xiang)連接(jie)。因為雙面板的面積比(bi)單(dan)面板大了一倍，而且因為布(bu)線(xian)可(ke)以(yi)互相(xiang)交錯(可(ke)以(yi)繞到(dao)另一面)，它(ta)(ta)更適合用在比(bi)單(dan)面板更復雜的電路上。

　　嚴格意義上來說雙(shuang)(shuang)(shuang)面(mian)(mian)(mian)(mian)板(ban)(ban)(ban)(ban)(ban)(ban)是(shi)(shi)電(dian)路(lu)板(ban)(ban)(ban)(ban)(ban)(ban)中(zhong)很(hen)重要的(de)(de)(de)一種PCB板(ban)(ban)(ban)(ban)(ban)(ban)，他(ta)的(de)(de)(de)用途是(shi)(shi)很(hen)大(da)的(de)(de)(de)，看(kan)一板(ban)(ban)(ban)(ban)(ban)(ban)PCB板(ban)(ban)(ban)(ban)(ban)(ban)是(shi)(shi)不(bu)是(shi)(shi)雙(shuang)(shuang)(shuang)面(mian)(mian)(mian)(mian)板(ban)(ban)(ban)(ban)(ban)(ban)也很(hen)簡單(dan)，相(xiang)信朋友們對單(dan)面(mian)(mian)(mian)(mian)板(ban)(ban)(ban)(ban)(ban)(ban)的(de)(de)(de)認識是(shi)(shi)完全可以把握的(de)(de)(de)了(le)(le)，雙(shuang)(shuang)(shuang)面(mian)(mian)(mian)(mian)板(ban)(ban)(ban)(ban)(ban)(ban)就是(shi)(shi)單(dan)面(mian)(mian)(mian)(mian)板(ban)(ban)(ban)(ban)(ban)(ban)的(de)(de)(de)延伸，意思是(shi)(shi)單(dan)面(mian)(mian)(mian)(mian)板(ban)(ban)(ban)(ban)(ban)(ban)的(de)(de)(de)線(xian)(xian)路(lu)不(bu)夠(gou)用從而轉(zhuan)到反(fan)面(mian)(mian)(mian)(mian)的(de)(de)(de)，雙(shuang)(shuang)(shuang)面(mian)(mian)(mian)(mian)板(ban)(ban)(ban)(ban)(ban)(ban)還(huan)有重要的(de)(de)(de)特征就是(shi)(shi)有導(dao)通孔。簡單(dan)點(dian)說就是(shi)(shi)雙(shuang)(shuang)(shuang)面(mian)(mian)(mian)(mian)走(zou)(zou)線(xian)(xian)，正反(fan)兩面(mian)(mian)(mian)(mian)都有線(xian)(xian)路(lu)!一句概括就是(shi)(shi)：雙(shuang)(shuang)(shuang)面(mian)(mian)(mian)(mian)走(zou)(zou)線(xian)(xian)的(de)(de)(de)板(ban)(ban)(ban)(ban)(ban)(ban)就是(shi)(shi)雙(shuang)(shuang)(shuang)面(mian)(mian)(mian)(mian)板(ban)(ban)(ban)(ban)(ban)(ban)!有的(de)(de)(de)朋友就要問了(le)(le)比如一塊板(ban)(ban)(ban)(ban)(ban)(ban)雙(shuang)(shuang)(shuang)面(mian)(mian)(mian)(mian)走(zou)(zou)線(xian)(xian)，但是(shi)(shi)只有一面(mian)(mian)(mian)(mian)有電(dian)子零件(jian)，這樣(yang)的(de)(de)(de)板(ban)(ban)(ban)(ban)(ban)(ban)到底是(shi)(shi)雙(shuang)(shuang)(shuang)面(mian)(mian)(mian)(mian)板(ban)(ban)(ban)(ban)(ban)(ban)還(huan)是(shi)(shi)單(dan)面(mian)(mian)(mian)(mian)板(ban)(ban)(ban)(ban)(ban)(ban)呢?答案是(shi)(shi)明(ming)顯的(de)(de)(de)，這樣(yang)的(de)(de)(de)板(ban)(ban)(ban)(ban)(ban)(ban)就是(shi)(shi)雙(shuang)(shuang)(shuang)面(mian)(mian)(mian)(mian)板(ban)(ban)(ban)(ban)(ban)(ban)，只是(shi)(shi)在雙(shuang)(shuang)(shuang)面(mian)(mian)(mian)(mian)板(ban)(ban)(ban)(ban)(ban)(ban)的(de)(de)(de)板(ban)(ban)(ban)(ban)(ban)(ban)材上裝上了(le)(le)零件(jian)而已。
