style="text-indent:25px">通常PCB是絕緣的防護(hù)層，可以保護(hù)銅線，也防止波焊時(shí)造成的短路，并節(jié)省焊錫之用量。在阻焊層上還會(huì)印刷上一層絲網(wǎng)印刷面(silk screen)。通常在這上面會(huì)印上文字與符號(hào)(大多是白色的)，以標(biāo)示出各零件在板子上的位置。絲網(wǎng)印刷面也被稱作圖標(biāo)面(legend)。采用印制板的主要優(yōu)點(diǎn)是:由于圖形具有重復(fù)性(再現(xiàn)性)和一致性，減少了布線和裝配的差錯(cuò)，節(jié)省了設(shè)備的維修、調(diào)試和檢查時(shí)間;設(shè)計(jì)上可以標(biāo)準(zhǔn)化，利于互換;布線密度高，體積小，重量輕，利于電子設(shè)備的小型化;利于機(jī)械化、自動(dòng)化生產(chǎn)，提高了勞動(dòng)生產(chǎn)率并降低了電子設(shè)備的造價(jià)。印制板的制造方法可分為減去法(減成法)和添加法(加成法)兩個(gè)大類。目前，大規(guī)模工業(yè)生產(chǎn)還是以減去法中的腐蝕銅箔法為主。</p><p
