style="text-indent:25px">SMT貼片加工價(jià)錢計(jì)算目前幾乎處于通明階段，幾錢一個(gè)點(diǎn)的算法很復(fù)雜。不過(guò)首先，需求明白“點(diǎn)”的概念，不同的公司采用的算法不同，但針對(duì)一塊PCB板來(lái)講，初的SMT貼片加工費(fèi)用總價(jià)是一樣的。 SMT貼片加工的次要目的是將貼片元器件貼裝到PCB的焊盤上，有的公司將一個(gè)焊盤計(jì)算為一個(gè)點(diǎn)，但也有將兩個(gè)焊點(diǎn)（例如一個(gè)0201的貼片電阻）計(jì)作一個(gè)點(diǎn)的情況。以焊盤計(jì)算為一個(gè)點(diǎn)為例。只需求計(jì)算PCB板上一切的焊盤數(shù)即可，但是遇到一些特殊的元器件，比如電感、大的電容、IC等。smt貼片機(jī)是SMT是表面組裝技術(shù)**設(shè)備又稱“貼裝機(jī)”、“表面貼裝系統(tǒng)”。北京無(wú)鉛SMT貼片生產(chǎn)廠家</p><p
