如何(he)選(xuan)擇上好的(de)的(de)SMT貼片(pian)加(jia)工(gong)廠(chang)？我們要(yao)選(xuan)擇貼片(pian)加(jia)工(gong)廠(chang)廠(chang)，首先要(yao)知(zhi)道(dao)smt貼片(pian)廠(chang)的(de)種類(lei)：一(yi)是(shi)(shi)(shi)定制(zhi)加(jia)工(gong)廠(chang)，只(zhi)(zhi)為某(mou)行業(ye)或(huo)某(mou)產(chan)品(pin)(pin)(pin)(pin)生(sheng)產(chan)。例如，只(zhi)(zhi)有手機主板(ban)、平(ping)板(ban)電(dian)(dian)(dian)腦(nao)、汽車電(dian)(dian)(dian)子、FPC軟件板(ban)、LED燈、LED顯示屏等。他們所有的(de)機器、輔助設(she)備(bei)、人(ren)(ren)(ren)(ren)才(cai)配套(tao)、檢測工(gong)具，都(dou)是(shi)(shi)(shi)按這種產(chan)品(pin)(pin)(pin)(pin)配套(tao)的(de)。雖(sui)然只(zhi)(zhi)做一(yi)個產(chan)品(pin)(pin)(pin)(pin)，但對外也(ye)稱為來料加(jia)工(gong)。二是(shi)(shi)(shi)規模型加(jia)工(gong)廠(chang)，是(shi)(shi)(shi)比較大型的(de)，機械生(sheng)產(chan)線多，生(sheng)產(chan)能(neng)力(li)高。具體分(fen)為取(qu)得品(pin)(pin)(pin)(pin)質的(de)類(lei)型和(he)低端取(qu)得廉價(jia)的(de)類(lei)型兩種。這兩種生(sheng)產(chan)方式，從字面上看可以(yi)理解如果你的(de)產(chan)品(pin)(pin)(pin)(pin)簡單，量大，就找(zhao)(zhao)低端的(de)。那樣的(de)話，價(jia)格當然會便宜。相反(fan)，你的(de)板(ban)子附加(jia)值(zhi)高，板(ban)子復(fu)雜，精度高，需要(yao)仔(zi)細找(zhao)(zhao)找(zhao)(zhao)，找(zhao)(zhao)出它(ta)的(de)質量型。基(ji)本上采購人(ren)(ren)(ren)(ren)員(yuan)及業(ye)務人(ren)(ren)(ren)(ren)員(yuan)著重(zhong)(zhong)在(zai)產(chan)品(pin)(pin)(pin)(pin)的(de)價(jia)格與交期(qi)上面；而工(gong)程(cheng)人(ren)(ren)(ren)(ren)員(yuan)則著重(zhong)(zhong)在(zai)技術、制(zhi)程(cheng)能(neng)力(li)與設(she)備(bei)上面；品(pin)(pin)(pin)(pin)管人(ren)(ren)(ren)(ren)員(yuan)則著重(zhong)(zhong)在(zai)產(chan)品(pin)(pin)(pin)(pin)的(de)質量管控；剩下的(de)則是(shi)(shi)(shi)大家都(dou)要(yao)重(zhong)(zhong)視的(de)。制(zhi)程(cheng)能(neng)力(li)評估：修補能(neng)力(li)、零件的(de)焊接(jie)及修補能(neng)力(li)、執行能(neng)力(li)、完整性、異形件如何(he)作(zuo)業(ye)、包(bao)裝如何(he)作(zuo)業(ye)、盤包(bao)裝如何(he)作(zuo)業(ye)、如何(he)避免(mian)打錯料、是(shi)(shi)(shi)否(fou)有電(dian)(dian)(dian)路(lu)板(ban)設(she)計給客戶參考、有沒有提供電(dian)(dian)(dian)路(lu)板(ban)設(she)計的(de)能(neng)力(li)。錫膏回溫、拆封、保(bao)存期(qi)限能(neng)力(li)。浙江電(dian)(dian)(dian)路(lu)板(ban)SMT貼片(pian)專業(ye)加(jia)工(gong)廠(chang)SMT生(sheng)產(chan)中有哪幾點不(bu)理想的(de)地(di)方?
