style="text-indent:25px">PCB表面處理工藝不同造成價格的多樣性，常見的有：OSP（抗氧化）、有鉛噴錫、無鉛噴錫（環(huán)保）、鍍金、沉金還有一些組合工藝等等，以上工藝價格越往后越貴。PCB本身難度不同造成的價格多樣性，兩種線路板上都有1000個孔，一塊板孔徑大于0.2mm與另一塊板孔徑小于0.2mm就會形成不同的鉆孔成本；如兩種線路板其他相同，但線寬線距不同，一種均大于4mil，一種均小于4mil，也會造成不同的生產(chǎn)成本；其次還有一些不走普通板工藝流程的設(shè)計也是加收錢的，比如半孔、埋盲孔、盤中孔、按鍵板印碳油。進口消費電子PCB電話PCB的價格是很多采購者一直很困惑的事情。</p><div

Boards）在極基本的PCB上零件集中在其中一面，導(dǎo)線則集中在另一面上（有貼片元件時和導(dǎo)線為同一面，插件器件再另一面）。因為導(dǎo)線只出現(xiàn)在其中一面，所以這種PCB叫作單面板（Single-sided）。因為單面板在設(shè)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。分為剛性電路板和柔性電路板、軟硬結(jié)合板。PCB的直觀上區(qū)別是柔性PCB是可以彎曲的。</p><p

(也即PowerPCB)、Altium designer (也即Protel)、FreePCB、CAM350等。PCB板按照線路板層數(shù)可分為單面板、雙面板、四層板、六層板以及其他多層線路板。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

mask）的顏色。是絕緣的防護層，可以保護銅線，也可以防止零件被焊到不正確的地方。在阻焊層上還會印刷上一層絲網(wǎng)印刷面（silk screen）。通常在這上面會印上文字與符號（大多是白色的），以標示出各零件在板子上的位置。絲網(wǎng)印刷面也被稱作圖標面（legend）。PCB板就是印制電路板，又稱印刷電路板，是電子元器件電氣連接的提供者。PCB中間膜是半透明的薄膜，由聚乙烯醇縮丁醛樹脂經(jīng)增塑劑塑化擠壓成型的一種高分子材料。PCB串擾是兩條信號線之間的耦合。天津醫(yī)療PCB廠家</p><p
