Cov ntawv luam tawm hluav taws xob tau siv dav hauv ntau cov khoom siv hluav taws xob thiab thev naus laus zis, ua rau lawv muaj txiaj ntsig zoo. Txawm hais tias nws yog lub xov tooj txawb, lub khoos phis tawj lossis lub tshuab nyuaj, koj yuav pom tias PCB yog lub luag haujlwm rau kev ua haujlwm ntawm lub cuab yeej. Yog hais tias cov ntawv luam tawm hluav taws xob muaj cov khoom siv tsis xws lossis tsim khoom, nws yuav ua rau cov khoom kawg rau kev ua tsis zoo thiab ua rau muaj kev tsis zoo. Nyob rau hauv cov xwm txheej no, cov tuam ntxhab yuav tsum rov qab siv cov cuab yeej thiab siv sijhawm ntau dua thiab cov khoom siv los kho qhov txhaum.
Qhov no yog ib qho tseem ceeb vim li cas feem ntau cov neeg tsim tawm tig mus rau PCB cov neeg tsim qauv thiab cov tuam ntxhab rau kev tsim qauv thiab kev kuaj mob.
Yog vim li cas PCB board?
Theem xeem ntawm PCB raug tsim yog yog ib ntu tseem ceeb tshaj plaws. Yog tias koj tsis kuaj koj lub rooj tsavxwm PCB, tej zaum yuav muaj qee qhov yuam kev thiab cov teeb meem uas tsis quav ntsej thaum lub sijhawm ua haujlwm ntau lawm. Cov teeb meem no tuaj yeem ua rau cov teb ua tsis tiav thiab tsis pom zoo. Txhawm rau kom txo tau lub sijhawm tsis ua tiav thiab tswj hwm cov neeg siv khoom txaus siab, nws yog ib qho tseem ceeb kom ua cov txheej txheem ntsuas hluav taws xob kom ntseeg tau tias cov ntawv luam tawm Circuit Court thiab cov khoom siv tau ua haujlwm tau tag nrho. Muaj ib tus txheej txheem xeem thoob plaws hauv theem ntau lawm, uas tso cai rau koj los txheeb xyuas qhov yuam kev thiab teeb meem ua ntej lawm ntau dua li qhov kawg xeem theem.
Cov ntawv luam tawm cov board tsim thiab tsim cov tuam txhab uas feem ntau ua tib zoo kuaj cov txheej txheem los xyuas kom meej tias cov ntawv luam tawm kawg yog qhov zoo tshaj plaws.
PCB Cheebtsam Kev Ntsuam Xyuas
Theem xeem ntu yog feem ntau yog ib theem kom txhij txhua thiab yuav tsum tau zoo rau kev nthuav dav. Tus PCB pawg thawj coj yog tsim ntawm ntau yam khoom siv nyuaj. Cov no suav nrog kev siv hluav taws xob, tiv taus, cov tendors, diodes thiab fuses. Cov no yog lub ntsiab nruab uas yuav tsum tau kuaj xyuas cov cim ntawm cov xwm txheej tsis xwm yeem thiab tsis zoo.
Peev xwm-muaj peev xwm hluav taws xob yog cov khoom siv hluav taws xob me me uas khaws lub zog hauv daim ntawv ntawm cov electrostatic teb. Peev lub peev xwm muaj lub luag haujlwm los thaiv qhov kev ntws ntawm ncaj qha tam sim no thiab ua rau nws muaj peev xwm khaws cia tam sim no thaum khaws lub zog. Txhawm rau kuaj cov contacitors cov cus paj, lub ntsuas hluav taws xob tau thov kom ntsuas seb lawv ua haujlwm li lawv ua haujlwm. Txwv tsis pub, cov txiaj ntsig sib txawv yuav tshwm sim, qhia luv luv ncig, topage, lossis capacitor tsis ua haujlwm.
Diode-a diode yog ib lub cuab yeej hluav taws xob me me uas tuaj yeem hloov tshiab hauv ib qho kev taw qhia. Thaum nws transmits tam sim no nyob rau hauv ib qho kev taw qhia, nws blocks rov qab tam sim no. Diode yog lub cuab yeej rhiab heev, thiab sim nws yuav tsum tau tu. Nws raug nquahu kom sab laj tus kws tshaj lij ua ntej xeem cov ntu rhiab heev los tiv thaiv kev puas tsuaj
Resistor-resistor yog ib qho ntawm lub ntsiab ntawm PCB board. Cov khoom siv hluav taws xob hauv cov khoom hluav taws xob muaj ob lo lus xaus uas tsim cov hluav taws xob los ntawm qhov tam sim no. Txhawm rau ntsuas cov kev tiv thaiv no, koj tuaj yeem siv Ohmmeter. Thaum cov tsis kam yog rho tawm, koj tuaj yeem siv cov digital motimeter thiab txuas cov ua rau kev tiv thaiv. Yog tias kev nyeem ntawv dhau lawm, nws yuav yog vim qhib lub resistor.
Txij li thaum tus PCB pawg thawj coj yog tsim cov hluav taws xob sib xyaw, nws yog qhov tseem ceeb heev los sim seb puas muaj cov kev ua txhaum lossis ua yuam kev uas yuav ua rau Circuit Court Board. Txhua tus tivthaiv yuav tsum tau saib xyuas thiab kuaj kom ua kom cov khoom lag luam luam tawm hluav taws xob ntawm nws lub peev xwm tag nrho
Fastline Circreet Co., Txwv.Siv peb cov ntsiab lus saum toj no raws li cov ntsiab lus tawg, thiab cov neeg siv khoom tuaj yeem xaiv cov chaw tsim khoom sab xis. Nyob rau tib lub sijhawm, peb yuav tsum them sai sai rau kev sib txuas lus thiab kev sib pauv nrog cov tuam txhab tsim, yog li ob sab thiab muaj txiaj ntsig zoo ", thiab zoo dua txhawb cov txiaj ntsig cov khoom tsim kev sib koom tes.
