Los ntawm PCB World,

Ntau tus neeg siv cov xim ntawm PCB kom paub qhov txawv ntawm lub rooj tsavxwm.Qhov tseeb, xim ntawm lub motherboard tsis muaj dab tsi cuam tshuam nrog kev ua haujlwm ntawm PCB.

PCB board, tsis yog tias tus nqi siab dua, nws yooj yim dua rau siv.

Cov xim ntawm PCB nto yog cov xim ntawm cov solder resist.Lub solder tiv thaiv tuaj yeem tiv thaiv qhov tshwm sim ntawm qhov tsis ncaj ncees lawm ntawm cov khoom siv, thiab ncua kev pab cuam lub neej ntawm lub cuab yeej, thiab tiv thaiv oxidation thiab corrosion ntawm cov khoom siv hluav taws xob.

Yog tias koj nkag siab txog PCB boards ntawm cov tuam txhab loj xws li Huawei thiab ZTE, koj yuav pom tias cov xim feem ntau yog ntsuab.Qhov no yog vim hais tias cov tshuab ntsuab yog cov paub tab thiab yooj yim tshaj plaws.

Ntxiv nrog rau ntsuab, cov xim ntawm PCB tuaj yeem piav qhia tias yog "tswb thiab xuav": dawb, daj, liab, xiav, xim matte, thiab txawm chrysanthemum, ntshav, dub, ci ntsuab, thiab lwm yam. Lub hav zoov ntawm dawb, vim nws yog qhov tsim nyog los ua cov khoom siv teeb pom kev zoo Cov xim siv, thiab siv lwm cov xim, feem ntau yog rau cov ntawv sau cov khoom.Nyob rau hauv tag nrho cov theem ntawm lub tuam txhab los ntawm R & D mus rau cov khoom tsaws, nyob ntawm seb qhov sib txawv ntawm kev siv ntawm PCB, lub rooj tsavxwm kev sim tej zaum yuav liab doog, lub rooj tsavxwm tseem ceeb yuav liab, thiab lub sab hauv ntawm lub computer yuav dub, uas yog cim. los ntawm xim.

Lub rooj tsav xwm PCB feem ntau yog lub rooj tsavxwm ntsuab ntsuab, tseem hu ua roj ntsuab.Nws daim npog ntsej muag yog tus qub tshaj plaws, pheej yig tshaj thiab nrov tshaj plaws.Ntxiv nrog rau cov cuab yeej paub tab, cov roj ntsuab muaj ntau yam zoo:

Hauv kev ua PCB, kev tsim cov khoom siv hluav taws xob suav nrog kev tsim cov rooj tsavxwm thiab patching.Thaum lub sijhawm ua haujlwm, muaj ntau yam txheej txheem los ntawm chav teeb daj, thiab ntsuab PCB board muaj qhov pom kev zoo tshaj plaws hauv chav teeb daj;thib ob, hauv SMT thaj ua haujlwm, cov tin yog siv.Cov kauj ruam ntawm, patching thiab AOI calibration tag nrho yuav tsum tau optical positioning calibration, thiab ntsuab hauv qab phaj ntsuas yog ntau tus phooj ywg rau kev txheeb xyuas.

Ib feem ntawm cov txheej txheem tshuaj xyuas tso siab rau cov neeg ua haujlwm saib xyuas (tab sis tam sim no lawv feem ntau siv kev sojntsuam ya ya tsis siv phau ntawv), ntsia ntawm lub rooj tsavxwm hauv lub teeb muaj zog, ntsuab yog tus phooj ywg rau ob lub qhov muag.Green PCBs kuj yog ib puag ncig zoo dua qub, thiab yuav tsis tso cov pa roj carbon monoxide thaum lawv rov ua dua ntawm qhov kub thiab txias.

Lwm cov xim PCB, xws li xiav thiab dub, yog doped nrog cobalt thiab carbon, raws li lawv muaj zog hluav taws xob conductivity, thiab muaj kev pheej hmoo ntawm luv luv Circuit Court.

Siv lub board dub ua piv txwv.Hauv kev tsim khoom, lub rooj tsav xwm dub feem ntau yuav ua rau muaj xim sib txawv vim muaj teeb meem ntawm cov txheej txheem thiab cov khoom siv raw, uas ua rau muaj qhov tsis zoo ntawm PCB siab.Cov kab ntawm lub rooj tsav xwm dub tsis yooj yim rau kev paub qhov txawv, uas yuav ua rau muaj kev nyuaj siab rau tom qab kev kho thiab kev debugging.Ntau lub chaw tsim khoom PCB tsis siv cov PCBs dub.Txawm hais tias nyob rau hauv kev lag luam tub rog thiab kev tswj hwm kev lag luam, cov khoom lag luam uas xav tau zoo heev siv ntsuab PCB substrates.

Tom ntej no, cia peb tham txog cov nyhuv ntawm solder mask number case xim ntawm lub rooj tsavxwm?

Rau cov khoom tiav, cov nyhuv ntawm cov inks sib txawv ntawm lub rooj tsavxwm yog feem ntau pom nyob rau hauv cov tsos, uas yog, txawm tias nws zoo los tsis zoo.Piv txwv li, ntsuab muaj xws li lub hnub ntsuab, lub teeb ntsuab, tsaus ntsuab, matt ntsuab, thiab lwm yam., cov xim yog lub teeb dhau lawm, nws yog ib qho yooj yim mus saib lub plug Cov tsos ntawm lub rooj tsavxwm tom qab lub qhov txheej txheem tsis zoo, thiab ib co manufacturers ' inks tsis zoo, cov resin thiab dye ratio yog teeb meem, yuav muaj teeb meem xws li npuas, thiab me ntsis kev hloov ntawm cov xim kuj yuav kuaj tau;qhov cuam tshuam rau cov khoom lag luam semi-tiav yog qhov tseem ceeb hauv cov ntsiab lus ntawm qhov nyuaj ntawm kev tsim khoom, qhov teeb meem no yog qhov nyuaj me ntsis los piav qhia.Cov xim sib txawv muaj cov txheej txheem xim sib txawv, xws li electrostatic txau, txau, thiab tshuaj ntsuam luam ntawv.Tus number case ratio kuj txawv.Ib qho yuam kev me ntsis yuav ua rau cov xim tshwm sim.teeb meem.

Txawm hais tias cov xim ntawm tus number case tsis cuam tshuam rau PCB lub rooj tsavxwm, lub thickness ntawm tus number case muaj kev cuam tshuam zoo rau lub impedance, tshwj xeeb tshaj yog rau cov dej-kub board, uas muaj kev tswj nruj heev ntawm cov tuab ntawm tus number case;lub thickness thiab npuas ntawm tus number case liab yog ib qho yooj yim los tswj, thiab tus number case liab npog ntawm kab, qee qhov tsis xws luag tuaj yeem npog, thiab cov tsos zoo nkauj dua, tab sis qhov tsis zoo yog tias tus nqi kim dua.Thaum kuaj pom, qhov pom liab thiab daj yog qhov ruaj khov dua, thiab xim dawb yog qhov nyuaj tshaj plaws los tswj.

Txhawm rau ua kom tiav, cov xim tsis muaj kev cuam tshuam rau kev ua haujlwm ntawm lub rooj tsavxwm tiav, thiab muaj kev cuam tshuam me me rau ntawm PCB sib dhos thiab lwm yam txuas;hauv PCB tsim, txhua qhov kev nthuav dav hauv txhua qhov txuas yog tswj hwm nruj, thiab lub rooj tsavxwm PCB dhau los ua tus yuam sij rau lub rooj tsavxwm zoo.PCB motherboards ntawm cov xim sib txawv yog tsim rau cov khoom muag.Nws tsis pom zoo kom koj siv xim raws li qhov tseem ceeb hauv kev ua PCB.
