Rau cov khoom siv hluav taws xob niaj hnub no, cov ntawv luam tawm Circuit Board (PCBs) tau dhau los ua ib feem tseem ceeb ntawm cov txheej txheem tsim.Cov kab hluav taws xob ntsuab me me no yog lub luag haujlwm txuas rau txhua qhov sib txawv ntawm cov khoom siv hluav taws xob ua ke thiab ua lub luag haujlwm tseem ceeb hauv nws txoj haujlwm tag nrho.
Raws li lub npe qhia, PCB yog qhov tseem ceeb ntawm lub rooj tsav xwm nrog cov ntawv luam tawm.Nws muaj cov khaubncaws sab nraud povtseg ntawm tooj liab thiab lwm yam ntaub ntawv conductive sandwiched ntawm cov khaubncaws sab nraud povtseg ntawm cov ntaub ntawv uas tsis yog-conductive xws li fiberglass.Cov khaubncaws sab nraud povtseg yog tom qab ntawd etched rau hauv cov qauv tshwj xeeb uas tso cai rau hluav taws xob tam sim no dhau los ntawm lub rooj tsavxwm.
Ib qho txiaj ntsig tseem ceeb ntawm kev siv PCBs yog tias lawv muab cov qib sib xws thiab qhov tseeb tsis sib xws los ntawm lwm txoj kev xaim.Txij li thaum cov circuits tau luam tawm mus rau lub rooj tsavxwm nrog qhov tseeb heev, muaj ntau qhov chaw tsawg dua rau kev ua yuam kev ntawm cov khoom siv hluav taws xob sib txuas.
Tsis tas li ntawd, PCBs yog qhov hloov tau zoo kawg thiab tuaj yeem tsim kom haum yuav luag txhua yam duab lossis qhov loj me, uas yog qhov tseem ceeb rau cov khoom siv hluav taws xob niaj hnub uas tau dhau los ua compact thiab portable.Qhov kev hloov pauv no txhais tau tias PCBs tuaj yeem siv rau hauv txhua yam ntawm cov cuab yeej hauv tsev ntse mus rau cov khoom siv kho mob.
Tau kawg, zoo li lwm qhov ntawm cov khoom siv hluav taws xob, PCB xav tau kev saib xyuas thiab tu kom zoo.Sij hawm dhau mus, lawv tuaj yeem ua puas los yog corrode, ua rau lub cuab yeej ua haujlwm tsis zoo lossis tsis ua haujlwm tag nrho.Qhov no yog vim li cas nws yog ib qho tseem ceeb rau cov tib neeg thiab cov lag luam los nqis peev hauv PCBs zoo thiab tshuaj xyuas lawv tsis tu ncua thiab hloov lawv raws li xav tau.
Zuag qhia tag nrho, nws yog qhov tseeb tias PCBs ua lub luag haujlwm tseem ceeb hauv kev tsim thiab kev ua haujlwm ntawm cov khoom siv hluav taws xob niaj hnub no.Los ntawm kev sib txuas cov khoom siv kom ntseeg tau tias muaj hluav taws xob zoo ib yam, lawv yog ib feem tseem ceeb ntawm kev siv tshuab thoob plaws peb.Raws li thev naus laus zis txuas ntxiv mus, nws yuav nthuav kom pom tias PCBs hloov zuj zus thiab hloov pauv li cas kom tau raws li qhov hloov pauv ntawm kev lag luam.
Hauv cov ntsiab lus, PCBs yog ib feem tseem ceeb ntawm cov khoom siv hluav taws xob niaj hnub no.Lawv muab precision thiab sib xws tsis sib xws los ntawm lwm txoj kev xaim thiab zoo tagnrho rau ntau yam khoom siv thiab kev siv.Thaum lawv xav tau kev saib xyuas thiab kev saib xyuas kom raug, PCBs yuav tsis muaj qhov xav tau txuas ntxiv mus ua lub luag haujlwm tseem ceeb hauv kev tsim cov thev naus laus zis yav tom ntej.
