Cov ntawv luam tawm Circuit Board tau siv dav hauv ntau yam khoom siv hluav taws xob thiab thev naus laus zis, ua rau lawv muaj txiaj ntsig zoo heev.Txawm hais tias nws yog lub xov tooj ntawm tes, lub computer lossis lub tshuab ua haujlwm, koj yuav pom tias pcb yog lub luag haujlwm rau kev ua haujlwm ntawm lub cuab yeej.Yog tias cov ntawv luam tawm Circuit Board muaj qhov tsis xws luag lossis teeb meem kev tsim khoom, nws yuav ua rau cov khoom kawg ua haujlwm tsis zoo thiab ua rau tsis yooj yim.Nyob rau hauv cov xwm txheej no, cov tuam txhab yuav tsum tau rov qab cov cuab yeej no thiab siv sijhawm ntau thiab cov peev txheej los kho qhov txhaum.
Qhov no yog ib qho ntawm cov laj thawj tseem ceeb vim li cas cov neeg tsim khoom feem ntau tig mus rau pcb tus tsim thiab cov chaw tsim khoom rau kev tsim khoom thiab kev sim.
Vim li cas thiaj yuav tsum tau kuaj pcb board?
Lub sijhawm kuaj ntawm PCB kev tsim khoom yog ib theem tseem ceeb tshaj plaws.Yog tias koj tsis kuaj koj lub rooj tsavxwm pcb, tej zaum yuav muaj qee qhov yuam kev thiab teeb meem uas tsis quav ntsej thaum lub sijhawm tsim khoom.Cov teeb meem no thaum kawg tuaj yeem ua rau kev ua tsis tiav thiab qhov tsis xws luag.Txhawm rau txo qhov tsis ua haujlwm thiab tswj cov neeg siv khoom txaus siab, nws yog ib qho tseem ceeb uas yuav tsum tau ua cov txheej txheem kuaj xyuas kom ntseeg tau tias cov ntawv luam tawm Circuit Board thiab cov khoom siv ua haujlwm tau zoo.Muaj cov txheej txheem kuaj thoob plaws hauv theem tsim khoom, uas tso cai rau koj txheeb xyuas qhov tsis raug thiab teeb meem ua ntej es tsis yog nyob rau theem kawg ntawm kev xeem.
Cov ntawv luam tawm Circuit Board tsim thiab cov tuam txhab tsim khoom feem ntau muaj cov txheej txheem kev sim thiab ua tib zoo xyuas kom ntseeg tau tias cov ntawv luam tawm zaum kawg yog qhov zoo tshaj plaws.
PCB Cheebtsam kuaj
Cov theem kev xeem feem ntau yog ib theem zoo thiab yuav tsum tau ua tib zoo saib xyuas kom meej.Lub pcb board yog tsim los ntawm ntau yam complex Cheebtsam.Cov no muaj xws li capacitors, resistors, transistors, diodes thiab fuses.Cov no yog cov khoom tseem ceeb uas yuav tsum tau kuaj xyuas txhua qhov cim qhia ntawm qhov tsis sib xws thiab ua haujlwm tsis zoo.
Capacitors-Capacitors yog cov khoom siv hluav taws xob me me uas khaws lub zog hauv daim ntawv ntawm electrostatic teb.Capacitors yog lub luag hauj lwm rau thaiv qhov ntws ntawm cov tam sim no ncaj qha thiab ua rau nws muaj peev xwm khaws cia tsis ncaj tam sim no thaum khaws cia lub zog.Txhawm rau kuaj cov capacitors, qhov voltage yog siv los ntsuas seb lawv puas ua haujlwm raws li qhov xav tau.Txwv tsis pub, cov txiaj ntsig sib txawv yuav tshwm sim, qhia txog luv luv Circuit Court, to, lossis capacitor tsis ua haujlwm.
Diode-A diode yog ib qho khoom siv hluav taws xob me me uas tuaj yeem hloov pauv tam sim no hauv ib qho kev taw qhia.Thaum nws kis tam sim no nyob rau hauv ib qho kev taw qhia, nws thaiv qhov rov qab tam sim no.Lub diode yog ib qho khoom siv rhiab heev, thiab kev sim nws yuav tsum tau saib xyuas.Nws raug nquahu kom sab laj nrog tus kws tshaj lij ua ntej kuaj cov khoom rhiab los tiv thaiv kev puas tsuaj
Resistor-Resistor yog ib qho ntawm cov khoom tseem ceeb ntawm pcb board.Cov khoom siv hluav taws xob me me no muaj ob lub terminals uas tsim hluav taws xob los ntawm qhov tam sim no.Txhawm rau kuaj cov kev tawm tsam no, koj tuaj yeem siv lub ohmmeter.Thaum qhov kev tawm tsam raug cais tawm, koj tuaj yeem siv lub tshuab digital multimeter thiab txuas cov coj mus rau qhov kev tawm tsam rau kev sim.Yog tias qhov kev nyeem ntawv siab dhau lawm, nws yuav yog vim qhov qhib resistor.
Txij li thaum lub rooj tsavxwm pcb yog tsim los ntawm ntau yam khoom siv hluav taws xob nyuaj, nws yog ib qho tseem ceeb heev uas yuav tsum tau kuaj seb lub pcb board puas muaj qhov yuam kev lossis qhov tsis zoo uas yuav ua rau lub rooj tsav xwm hauv Circuit Court malfunction.Txhua yam yuav tsum tau saib xyuas thiab sim ua kom lub luag haujlwm ntawm lub rooj tsav xwm luam tawm ntawm nws lub peev xwm
Fastline Circuits Co., Ltd.siv qhov saum toj no peb yam raws li cov ntsiab lus tawg, thiab cov neeg siv khoom tuaj yeem xaiv cov chaw tsim khoom zoo.Nyob rau tib lub sijhawm, peb yuav tsum xyuam xim rau kev sib txuas lus thiab kev sib pauv nrog cov neeg tsim khoom, kom ob tog tuaj yeem tsim lub xeev "kev sib raug zoo thiab yeej-yeej" lub xeev, thiab txhawb nqa cov khoom lag luam kev koom tes zoo dua.
