隨著電子科技不斷發(fā)展，PCB技術(shù)也隨之發(fā)生了巨大的變化，制造工藝也需要進(jìn)步。同時(shí)每個行業(yè)對PCB線路板的工藝要求也逐漸的提高了，就比如手機(jī)和電腦的電路板里，使用了金也使用了銅，導(dǎo)致電路板的優(yōu)劣也逐漸變得更容易分辨。現(xiàn)在仁遠(yuǎn)就帶大家了解PCB板的表面工藝，對比一下不同的PCB板表面處理工藝的優(yōu)缺點(diǎn)和適用場景。單純的從外表看，電路板的外層主要有三種顏色：金色、銀色、淺紅色。按照價(jià)格歸類：金色較貴，銀色次之，淺紅色的低價(jià)，從顏色上其實(shí)很容易判斷出硬件廠家是否存在偷工減料的行為。不過電路板內(nèi)部的線路主要是純銅，也就是裸銅板。優(yōu)缺點(diǎn)很明顯：優(yōu)點(diǎn)：成本低、表面平整，焊接性良好(在沒有被氧化的情況下)。缺點(diǎn)：容易受到酸及濕度影響，不能久放，拆封后需在2小時(shí)內(nèi)用完，因?yàn)殂~暴露在空氣中容易氧化;無法使用于雙面板，因?yàn)榻?jīng)過前列次回流焊后第二面就已經(jīng)氧化了。如果有測試點(diǎn)，必須加印錫膏以防止氧化，否則后續(xù)將無法與探針接觸良好。純銅如果暴露在空氣中很容易被氧化，外層必須要有上述保護(hù)層。而且有些人認(rèn)為金黃色的是銅，那是不對的想法，因?yàn)槟鞘倾~上面的保護(hù)層。所以就需要在電路板上大面積鍍金，也就是我之前帶大家了解過的沉金工藝。 </p><p>它能夠被全自動鍵入和解決。這使其特別適合迅速安全性的數(shù)據(jù)交換及其靠譜的自動化技術(shù)工作內(nèi)容。PCB生產(chǎn)制造信息中較繁雜的是圖型一部分的敘述，GerberRS-274X格式包括了pcb線路板各層圖象的詳細(xì)敘述，具備pcb線路板圖型顯像必須的全部原素，已不必須附加的外界文件。自然，Gerber格式也存有著不夠，針對PCB生產(chǎn)制造來講，除開精細(xì)敘述數(shù)據(jù)信號和平面設(shè)計(jì)圖層上銅形圖象信息，還必須附加特定例如板才，堆疊構(gòu)造信息，打孔數(shù)據(jù)信息（Gerber文件能夠界定打孔數(shù)據(jù)信息。殊不知由于歷史時(shí)間緣故，Excellon格式更常常被作為打孔格式），阻焊油墨色調(diào)，假如做主控芯片操縱，還必須附加特定必須做特性阻抗監(jiān)管的重要布線這些。針對這種填補(bǔ)信息GerberRS-274X并沒有界定有關(guān)的規(guī)范，因此大多數(shù)依據(jù)板廠出示的制版工藝規(guī)定word模版添充必需的制版工藝規(guī)定信息，轉(zhuǎn)化成PDF文檔與Gerber、打孔、網(wǎng)表等有關(guān)信息一并裝包發(fā)給板廠。盡管現(xiàn)在有例如ODB++、IPC-2581、GerberX2等新的數(shù)據(jù)標(biāo)準(zhǔn)來處理GerberRS-274X的缺點(diǎn)，比如GerberX2做為GerberRS-274X規(guī)范的拓展版本號，加上原先缺少的例如堆疊界定、焊層和焊盤特性、必須做特性阻抗操縱監(jiān)管的重要布線。用以檢測的網(wǎng)表，并往下完成適配。同樣是PCB設(shè)計(jì)、開發(fā)，居然差別這么大，快速打樣,精選材質(zhì)！別選錯了！</p><div
