Shenzhen Chengyuan Industrial Automation Equipment Co., Ltd. muab cov kev daws teeb meem thiab cov khoom siv automation rau SMT ntse Hoobkas ntau lawm kab.
SMT mounter, lead-free reflow soldering, lead-free yoj soldering, PCB conformal xim txheej tshuab, tshuab luam ntawv, kho qhov cub.
Tsis muaj qhov tsis ntseeg tias cov ntawv luam tawm Circuit Board (PCB) yog cov cuab yeej tseem ceeb hauv tib neeg thev naus laus zis.
PCBs tau dhau los ua ib txoj hauv kev los txhim kho cov txheej txheem tsim khoom ntawm cov khoom siv hluav taws xob.Yav dhau los, cov khoom siv tes ua hluav taws xob no yuav tsum tau hloov los ntawm cov ntawv luam tawm Circuit Board.Qhov no yog vim tias ntau lub luag haujlwm yuav raug muab tso rau hauv lub rooj tsavxwm.
Sib piv lub rooj tsav xwm Circuit Court ntawm lub tshuab xam zauv xyoo 1968 nrog lub motherboard ntawm lub computer niaj hnub.
1. Xim.
Txawm hais tias qee tus neeg tsis paub tias PCB yog dab tsi, lawv feem ntau paub tias PCB zoo li cas.Yam tsawg kawg lawv zoo li lawv muaj ib txwm style, uas yog ntsuab.Qhov ntsuab no yog cov xim pob tshab ntawm lub ntsej muag lub ntsej muag iav xim.Txawm hais tias lub npe ntawm lub npog ntsej muag yog lub npog ntsej muag, nws lub luag haujlwm tseem ceeb yog los tiv thaiv lub voj voog ntawm cov dej noo thiab hmoov av.
Raws li yog vim li cas lub npog ntsej muag yog ntsuab, lub ntsiab yog vim li cas ntsuab yog tus qauv kev tiv thaiv tub rog.Thawj thawj zaug, PCBs hauv cov cuab yeej siv tub rog tau siv lub qhov ncauj qhov ntswg hauv thaj teb los tiv thaiv kev ntseeg tau ntawm lub voj voog.
Cov qhov ncauj qhov ntswg tam sim no muaj ntau yam xim, suav nrog dub, liab, daj, thiab ntau dua.Tom qab tag nrho, ntsuab tsis yog tus qauv kev lag luam.
2. Leej twg tsim lub PCB?
Cov ntawv luam tawm ntxov tshaj plaws tuaj yeem taug qab mus rau Austrian engineer Charles Ducas hauv xyoo 1920, uas tau npaj lub tswv yim ntawm kev ua hluav taws xob nrog tus cwj mem ( luam ntawv tooj dag nyob rau hauv qab phaj).Nws siv tshuab electroplating los ua cov xov hlau ncaj qha rau ntawm qhov chaw ntawm lub insulator thiab ua ib qho qauv PCB.
Cov hlau xaim ntawm lub rooj tsav xwm hauv Circuit Court yog tooj dag, ib qho hlau ntawm tooj liab thiab zinc.Qhov kev tsim tawm cuam tshuam no tshem tawm cov txheej txheem sib txuas ntawm cov khoom siv hluav taws xob, ua kom muaj kev ntseeg siab ntawm kev ua haujlwm hauv Circuit Court.Cov txheej txheem no tsis tau nkag mus rau theem kev thov kom txog thaum kawg ntawm Ntiaj Teb Tsov Rog II.
3. Mark.
Muaj ntau cov cim dawb ntawm lub rooj tsav xwm ntsuab.Tau ntau xyoo, tib neeg tsis nkag siab tias vim li cas cov ntawv dawb no hu ua "silkscreen layers".Lawv feem ntau yog siv los txheeb xyuas cov ntaub ntawv tiv thaiv ntawm lub rooj tsav xwm hauv Circuit Court thiab lwm cov ntsiab lus ntsig txog lub rooj tsav xwm hauv Circuit Court.Cov ntaub ntawv no tuaj yeem pab cov kws tsim hluav taws xob hauv hluav taws xob tshawb xyuas lub rooj tsavxwm rau qhov tsis raug.
