Nyob rau hauv daim teb ntawm electronics, multure-multure pcb (printered Circuit Court Board) ua si yog ib lub luag haujlwm tseem ceeb. Nws tsim qauv thiab chaw tsim khoom muaj qhov cuam tshuam muaj txiaj ntsig ntawm kev ua tau zoo thiab kev ntseeg tau ntawm cov khoom siv hluav taws xob niaj hnub no. Kab lus no yuav delve rau hauv nws cov ntsiab lus tseem ceeb, kev txiav txim siab tsim, thiab cov chaw thov kom muab cov kev pom dav dav. Los ntawm kev txheeb xyuas nws, peb tuaj yeem nkag siab zoo nws qhov tseem ceeb hauv cov tshuab hluav taws xob.
1, tus tsim ntawm cov-txheej pcb board tsis yog ib pawg yooj yim ntawm ntau-txheej cov laug cam, tab sis kev sib raug zoo sib txawv. Hauv cov theem tsim, thawj qhov uas yuav tsum xav txog yog qhov nyuaj thiab ntom ntawm Circuit Court. Nrog kev ua haujlwm txuas ntxiv ntawm kev ua haujlwm hauv cov khoom siv hluav taws xob niaj hnub, yog li nws tus qauv xav tau kom tau raws li qhov yuav tsum tau ua kom muaj qhov sib luag thiab ntau txoj haujlwm. Nyob rau tib lub sijhawm, cov kev ua tau zoo xav tau cov khoom siv hluav taws xob kuj nce ntxiv, thiab lawv cov qauv xav tau kom ntseeg tau tias qhov kev ruaj ntseg thiab kev ntseeg tau ntawm kev sib kis teeb liab.
2, Kev tsim qauv tsim ntawm cov txheej txheem pcb tseem yog qhov tseem ceeb. Hauv kev tsim theem tsim, cov txheej txheem siab tshaj plaws thiab thev naus laus zis yog qhov tseem ceeb heev. Los ntawm kev siv cov lus Lamination siab dua, qhov zoo ntawm interlayer kev twb kev txuas tuaj yeem txhim kho kom muaj kev ruaj khov ntawm kev sib kis tau pom. Ib qho ntxiv, kev xaiv tsim nyog xaiv kuj yog ib qho uas tsis tuaj yeem tsis quav ntsej hauv cov txheej txheem tsim khoom, yog li nws yog qhov tsim nyog los yuav tsum muaj cov khoom siv tsim nyog raws li cov xwm txheej tshwj xeeb hauv kev tsim khoom.
3, multure-pcb board muaj ntau cov kev siv hauv teb ntawm cov khoom siv hluav taws xob. Ua ntej tshaj plaws, nws plays lub luag haujlwm tseem ceeb hauv cov khoom siv hluav taws xob siab, xws li cov khoom sib txuas lus, kho tshuab computer thiab lwm yam. Nws lub siab ntom ntom thiab ruaj khov tso cai rau cov khoom siv no kom tau zoo dua ua tau zoo dua li cov neeg yuav tsum tau ua. Qhov thib ob, hauv kev thaj chaw ntawm cov khoom siv hluav taws xob hauv tsheb, nws tseem siv tau hauv lub tsheb hluav taws xob tshuab, xws li kev lom zem, lom ze thiab lwm yam. Vim yog lub siab ntseeg tau thiab cov kev xav tau ntawm cov peev txheej automanics, multure-multi-pcb cov laug cam tau dhau los ua qhov tsis tseem ceeb. Tsis tas li ntawd, nws kuj tau pom nws qhov zoo tshwj xeeb hauv kev ua liaj ua teb cov cuab yeej siv kho mob, kev tswj hwm thiab lwm yam.
Ua ntej, cia peb tsom rau kev tsim khoom ntawm PCB ob-txheej cov laug cam. Niaj hnub nimno pcb tsim feem ntau siv dhau los ntawm cov qauv hluav taws xob los ntawm cov qauv ntawm tooj liab thiab tom qab ntawd siv tshuaj lom neeg rau corrode. Cov txheej txheem no yuav tsum tsis tsuas muaj cov khoom siv siab-precision, tab sis kuj ua nruj kev tswj cov txheej txheem kom ntseeg tau tias qhov zoo thiab ruaj khov ntawm lub rooj tsavxwm. Nyob rau hauv kev tsim qauv txuas ntxiv ntawm PCB kev tsim qauv, cov txheej txheem tshiab thiab cov ntaub ntawv txuas ntxiv tawm, muab kev txhawb nqa zoo rau nws txoj kev txhim kho zoo.
Hauv daim teb ntawm daim ntawv thov, PCB ob-txheej pawg thawj coj ob chav tau siv dav hauv txhua hom khoom siv hluav taws xob. Los ntawm cov neeg siv khoom siv hluav taws xob rau kev tswj hwm kev lag luam, los ntawm cov cuab yeej kho mob los rau kev sib txuas lus, nws ua lub luag haujlwm tseem ceeb. Nws qhov kev ua tau zoo sib luag thiab kev ntseeg tau zoo ua nws tsis tseem ceeb ntawm cov khoom lag luam hauv niaj hnub no. Nyob rau tib lub sijhawm, nws tsim kev tsim tawm kuj tseem muab ntau ntxiv rau cov ntawv thov, kom tau raws li cov kev xav tau ntawm txawv teb rau pawg thawj coj.
Txawm li cas los xij, nrog kev hloov kho lub nriab nruam thiab muaj kev sib txawv ntawm cov khoom hluav taws xob, qhov yuav tsum tau siv rau PCB ob-txheej cam-txheej muaj nce ntxiv. Nyob rau yav tom ntej, peb tuaj yeem tos ntsoov rau qhov muaj peev xwm nce ntom thiab siab dua PCB ob--txheej ua kom tau raws li cov kev xav tau ntawm cov khoom siv hluav taws xob tshiab. Kev ua haujlwm txuas ntxiv ntawm cov khoom siv kev tsim khoom siv yuav txhawb nws txoj kev txhim kho ntawm thinner thiab kev ua haujlwm tshiab rau kev tsim kho tshiab hauv cov khoom hluav taws xob.
1. Cia peb muaj kev nkag siab tob ntawm cov qauv tshwj xeeb ntawm 4-txheej PCB Board.
Ib pawg thawj coj feem ntau muaj ob txheej ntawm tus neeg kos npe sab hauv thiab ob txheej ntawm sab nraud substrate. Tus ciav hlau sab hauv yog lub luag haujlwm rau kev sib txuas rau ntau cov hluav taws xob los ua cov txheej txheem, thaum cov txheej txheej sab nraud ua raws li kev txhawb nqa thiab rwb thaiv tsev. Cov qauv tsim no tso cai rau cov kws tsim hluav taws xob los npaj Circuit Court ntau yooj yim, txhim kho kev sib koom ua ke thiab kev ua tau zoo ntawm Circuit Court.
2, cov txheej txheem kom tau zoo ntawm 4-txheej PCB Board yog nws cov teeb liab kev sib cais zoo.
Lub puab txheej txheem ntsia hlau tau sib cais los ntawm hluav taws xob rwb thaiv tsev cov khoom siv, ua rau muaj kev sib cais ntawm cov teeb liab sib txawv. Qhov kev teeb tsa teeb liab no yog qhov tseem ceeb rau cov khoom siv hluav taws xob nyuaj thiab cov txheej txheem loj thiab muaj kev cuam tshuam loj hauv cov cim hauv cov cim, thiab ua kom muaj kev ntseeg tau ntawm cov khoom siv.
3, 4 Txheej PCB Board qauv qauv tsim kuj tseem muaj peev xwm ua rau kub dissipation.
Cov khoom siv hluav taws xob ua kom muaj cua sov ntau zog ua kom muaj cua sov ntau ntau thaum lub sijhawm ua haujlwm, thiab ua kom sov sov dissipation yog qhov tseem ceeb rau kev ua haujlwm ib txwm ntawm cov cuab yeej. Lub 4-txheej PCB Board kuj tseem nce cov thermal conductivity channel los ntawm kev nce sab hauv txheej sab hauv txheej, uas pab hloov pauv thiab ua kom sov. Qhov no tso cai rau cov khoom siv hluav taws xob kom zoo dua qub lub sijhawm ua haujlwm ruaj khov thaum lub sijhawm ua haujlwm siab, txuas ntxiv kev pabcuam lub neej.
4, 4-txheej pcb board tseem ua tau zoo nyob rau hauv cov nqe lus ntawm xaim.
Lub puab txheej txheem Ciaj uas tau tso cai rau cov qauv txuas ntxiv thiab cov qauv hlau hluav taws xob ntxiv, txo qhov chaw hauv qhov chaw ntawm Circuitfail. Qhov no yog qhov tseem ceeb rau lub teeb yuag thiab miniaturized Electronic ntaus ntawv tsim. Nyob rau tib lub sijhawm, cov wiring wiring kuj muab tau rau kev koom ua ke ntawm cov khoom siv hluav taws xob sib txawv, kom cov khoom siv hluav taws xob tuaj yeem tswj tau muaj zog ua haujlwm thaum ua me me.
Lub 4-txheej Pcb Board qauv ua haujlwm tseem ceeb hauv kev tsim kho tshiab, thiab kub dissipation rau cov khoom siv hluav taws xob, ua rau cov khoom siv hluav taws xob, ua kom zoo rau ntau yam kev siv. Nrog kev txhim kho kev kawm txuas ntxiv ntawm kev tshawb fawb thiab thev naus laus zis, peb tuaj yeem cia siab 4-txheej pcb cov laug cam los qhia cov kev hloov tshiab ntau ntxiv, nqa cov kev hloov pauv ntau dua thiab tawg mus rau kev siv hluav taws xob.
Noj ua ke, ntau-txheej pcb board li ib qho tseem ceeb hauv tshuab hluav taws xob niaj hnub no, nws tsim qauv thiab kev tsim khoom yog qhov tseem ceeb heev. Nyob rau hauv Circuit Court tsim theem, qhov nyuaj thiab ceev ntawm Circuit Court yuav tsum tau txiav txim siab. Hauv kev tsim khoom theem, nws yog qhov tsim nyog yuav tsum tau siv cov txheej txheem siab thiab thev naus laus zis thiab xaiv cov ntaub ntawv zoo. Nws cov kev siv ntau ntawm cov ntawv thov tau sib txuas lus xws li kev sib txuas lus, khoos phis tawm, thiab lub hauv paus tsim nyog rau kev ua tau zoo thiab kev ntseeg tau ntawm ntau yam khoom siv hluav taws xob. Nyob rau hauv lub neej yav tom ntej, nrog kev tsim kho cov tshuab hluav taws xob, nws cov qauv thiab kev tsim khoom yuav txuas ntxiv rau qhov chaw tshiab, tab sis nws tseem yuav muab qhov chaw dav dav rau kev txhim kho cov khoom siv hluav taws xob.
