Thaum nws los txog rau cov khoom siv hluav taws xob, cov ntawv luam tawm Circuit Board (PCBs) yog ib feem tseem ceeb ntawm kev tsim thiab tsim cov txheej txheem.Yooj yim muab, PCB yog ib lub rooj tsavxwm ua los ntawm cov khoom siv tsis zoo nrog cov kab hluav taws xob lossis cov kab txuas txuas ntau yam khoom siv hluav taws xob xws li resistors, capacitors thiab transistors.
Kev tsim PCB suav nrog kev tsim cov txheej txheem ntawm kev sib txuas thiab cov khoom sib txuas ntawm lub rooj tsav xwm hauv Circuit Court, uas yog qhov tseem ceeb rau kev ua haujlwm kom zoo thiab kev ntseeg siab ntawm cov khoom.Raws li kev siv thev naus laus zis txuas ntxiv mus, qhov kev xav tau ntawm kev tsim PCB zoo thiab kev tsim kho txuas ntxiv nce ntxiv.
Cov txiaj ntsig ntawm PCB Design
PCB tsim muaj ntau qhov zoo dua li cov kab hluav taws xob thiab kev tsim kho ntawm cov hluav taws xob hluav taws xob.Cov no suav nrog:
1. Kev txuag chaw: PCBs tshem tawm qhov kev xav tau ntawm cov xov hlau loj, yog li cov khoom siv hluav taws xob me me tuaj yeem tsim tau.
2. Durability: Vim hais tias PCBs yog tsim los ntawm cov ntaub ntawv uas muaj zog thiab muaj zog mechanical kev sib txuas, lawv tuaj yeem tiv taus qhov kub thiab txias, av noo, thiab kev co.
3. Kev sib raug zoo: PCBs yog tsim thiab sib sau ua ke raws li kev tswj xyuas nruj, yog li muab kev ua haujlwm zoo ib yam.
4. Flexibility: Cov qauv tsim ntawm PCB tuaj yeem hloov kho kom tau raws li cov kev xav tau tshwj xeeb, suav nrog qhov loj, cov duab thiab cov txheej txheem ntau lawm.
5. Tus nqi tsim nyog: PCBs txo cov nqi tsim khoom ntawm cov khoom siv hluav taws xob vim tias lawv tau nrawm dua thiab yooj yim rau kev tsim dua li cov txheej txheem kev sib txuas.
Dab tsi yog koom nrog hauv PCB tsim?
PCB tsim muaj ntau theem thiab cov txheej txheem yuav txawv nyob ntawm qhov nyuaj ntawm qhov project.Txawm li cas los xij, qee cov kauj ruam uas koom nrog suav nrog:
1. Schematic capture: Qhov no suav nrog kev kos duab kos duab ntawm lub tshuab hluav taws xob, suav nrog kev sib txuas thiab qhov tseem ceeb ntawm txhua qhov khoom.
2. PCB Layout: Qhov no yog qhov chaw tsim khoom xa mus rau lub rooj tsav xwm lub cev lossis "canvas" thiab cov khoom siv thiab cov khoom raug muab tso rau kom zoo.
3. PCB fabrication: Tom qab kev teeb tsa tiav lawm, lub rooj tsav xwm hauv Circuit Court yuav dhau los ntawm ntau lub tshuab ua haujlwm nrog rau kev sib tsoo, drilling, soldering thiab kuaj.
4. Kev sib dhos: Qhov no yog qhov uas cov khoom siv hluav taws xob txuas nrog rau saum npoo ntawm lub rooj tsavxwm los ntawm cov txheej txheem hu ua Surface Mount Technology (SMT).
5. Kev Ntsuas thiab Kev Ntsuas: Ib zaug sib sau ua ke, lub rooj tsavxwm yuav raug rau ntau yam kev ntsuam xyuas thiab kev txheeb xyuas kom ntseeg tau tias txhua qhov kev sib txuas yog qhov tseeb thiab cov qauv tsim ua haujlwm zoo.
nyob rau hauv xaus
PCB tsim yog ib qho tseem ceeb ntawm kev tsim khoom siv hluav taws xob.Nrog lawv cov txiaj ntsig ntau, nws tsis yog qhov xav tsis thoob tias PCBs yog qhov kev xaiv nrov ntawm cov kws tsim hluav taws xob thiab cov tuam ntxhab thoob ntiaj teb.Raws li kev siv thev naus laus zis txuas ntxiv mus, PCB tsim yuav yog qhov tseem ceeb rau cov kws tshaj lij hauv kev ua haujlwm.Nrog rau kev cob qhia thiab cov peev txheej tsim nyog, txhua tus tuaj yeem dhau los ua tus kws tsim qauv PCB uas tuaj yeem tsim cov khoom siv hluav taws xob zoo tshaj plaws raws li cov kev xav tau tshwj xeeb thiab cov kev xav tau.
