2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:28

Txhua lub sijhawm kuv tsim PCB Kuv xav thawb kuv qhov txwv me ntsis thiab sim qee yam uas kuv tsis tau sim ua ntej, lub sijhawm no kuv xav ntxiv qhov muaj peev xwm los ua haujlwm rau lub rooj tsavxwm no yam tsis muaj tus programmer sab nraud. Kuv pom qee qhov pheej yig USB rau UART hloov pauv hu ua CH340G, qhov teeb meem yog tias kuv tsis tau siv dua ua ntej thiab nws tsis zoo sau tseg hauv internet. Thaum kawg kuv tau txais nws ua haujlwm, Kuv xav tau ntxiv 3 lub capacitors xwb. Thiab kuv xav tias tsis txhob ua cov vis dis aus hais txog qhov haujlwm no, Kuv yuav ua cov vis dis aus hais txog qhov kuv daws teeb meem li cas. Qee cov lus qhia thiab kev dag rau koj cov teeb meem PCB.

Kauj Ruam 1: Tua Tag Nrho Cov Cheeb Tsam

Thawj kauj ruam yog txhawm rau ua kom tag nrho cov khoom siv, txhua yam ntawm lawv, tsis yog ob peb los kuaj PCB, txhua qhov khoom siv uas yuav tsum yog ntawm PCB kawg. Txwv tsis pub, koj yuav tsis ntsuam xyuas PCB tag. Nws tuaj yeem ua haujlwm tau zoo yam tsis muaj qee yam khoom siv tab sis thaum koj muab tshuaj txhuam tag nrho ntawm nws nws tuaj yeem nres ua haujlwm tag.

Kauj Ruam 2: Kuaj Koj Li PCB

Txhawm rau nrhiav seb puas muaj qhov yuam kev, sim koj li PCB. Yog tias muaj microcontroller, sau ib daim duab los ntsuas txhua qhov haujlwm ntawm koj li PCB. Txheeb xyuas txhua tus ntawm ib zaug lossis ib zaug. Yog tias txhua yam ua haujlwm tau zoo tsis txhob txhawj xeeb zoo siab tab sis yog tias muaj qee yam tsis raug, nyeem txuas ntxiv. Yog tias koj tsis muaj lub microcontroller tsuas yog sim koj lub Circuit nrog lub multimeter lossis lub zog nws thiab ntsuas yog tias nws ua haujlwm raws li nws yuav tsum tau ua.

Kauj Ruam 3: Txheeb Xyuas Kev Sib Txuas

Yog tias koj pom tias koj li PCB tsis ua haujlwm raws li nws yuav tsum tau ua thawj zaug yog los tshuaj xyuas txhua qhov kev sib txuas nrog lub ntsuas cua. Txheeb kom luv lossis qhib cov kab hluav taws xob. Teem multimeter rau ntsuas ohms lossis rau hom buzzer thiab txheeb xyuas txhua qhov kev sib txuas, kom yooj yim siv koj cov txheej txheem thiab txheej txheem PCB.

Yog tias koj muaj kev nkag mus rau lub tshuab tsom me me txawm tias ib qho yooj yim thiab xav tau los daws teeb meem ntawm cov khoom siv SMD, tej zaum qhov no yog kev daws teeb meem zoo rau koj. Kuv tab tom siv lub tshuab tsom iav qee zaum los tshuaj xyuas yog tias muaj luv lossis tsuas yog txhawm rau txheeb xyuas yog tias kuv tau siv qee yam kom raug. Zuag qhia tag nrho nws tsis muaj txiaj ntsig zoo hauv khw hluav taws xob, thiab qhov no tsis yog yam uas koj yuav tsum muaj tab sis thaum koj ua haujlwm nrog cov khoom me me nws zoo rau muaj.

Kauj Ruam 4: Txheeb Xyuas Koj Cov Qauv thiab PCB Layout

Yog tias txhua yam ntawm PCB zoo li ua haujlwm tau zoo, saib cov txheej txheem thiab txheej txheem PCB, tej zaum nug tus phooj ywg los tshuaj xyuas nws nrog saib tshiab. Sim nrhiav seb yam twg yuav ua rau muaj teeb meem. Qhov no yog cov kauj ruam pom tseeb tab sis qee zaum siv sijhawm ib hnub thiab saib cov txheej txheem hnub tom ntej muab rau koj qhov kev pom tshiab, nws yog txoj hauv kev yooj yim kom pom qhov ua yuam kev (zoo li VCC txuas nrog ob sab ntawm LED), Ua kom pom tseeb yog qhov tseem ceeb nyob ntawd, yog tias koj muaj cov phiaj xwm meej nws zoo dua rau koj thiab nws zoo dua rau lwm tus.

Kauj Ruam 5: Sim Nrhiav Tshuaj Online:

Yog tias muaj qee qhov khoom siv uas tsis ua haujlwm, sim google lawv thiab nrhiav lwm tus tib neeg cov txuj ci uas siv koj ib feem, txheeb xyuas seb lawv txuas nws li cas rau lwm qhov ntawm lawv txoj haujlwm thiab nrhiav qhov sib txawv ntawm cov lej thiab koj li cas. Tau kawg nco ntsoov tias tsis yog txhua yam uas koj pom hauv is taws nem yog qhov tseeb, tab sis yog tias ib feem tau txuas nrog tib txoj hauv kev ntawm ntau qhov kev qhia peb tuaj yeem xav tias qhov no yog yuav ua li cas.

Kauj Ruam 6: Thov Kev Pab ntawm Lub Rooj Sib Tham:

Kuv tsis nyiam qhov no tej zaum vim yog cov khoom siv hluav taws xob hauv zej zog hauv tebchaws Poland, tab sis yog tias koj tsis tuaj yeem nrhiav kev daws teeb meem rau koj, sim thov kev pab ntawm lub rooj sab laj. Muaj ntau cov khoom siv hluav taws xob uas yuav zoo siab tshaj los pab koj, Ua zoo, tshaj tawm koj cov phiaj xwm thiab piav qhia koj cov teeb meem kom ntxaws li koj tuaj yeem ua tau. Vam tias nyob hauv ib hnub lossis ob tus kws tshaj lij hluav taws xob yuav pab daws koj cov teeb meem.

Kauj ruam 7: Kho nws

Thaum koj pom tag nrho cov teeb meem sim kho lawv, tej zaum yuav siv cov kab hluav taws xob, lub tshuab hluav taws xob lossis txiav kab nrog kuv riam ib yam li kuv tau ua. Txhawm rau txuag qee cov nyiaj sim kho teeb meem ntawm PCB uas koj twb muaj lawm, tom qab ntawd hloov koj lub tswv yim thiab rov ua dua koj li PCB.

Thiab ntawm no yog cov lus qhia yooj yim kom tsis txhob ua yuam kev ntawm koj li PCB nws hu ua kev tsim qauv. Ua ntej xaj PCB lossis txawm tias ua ntej yuav kos duab, ua qauv koj lub tswv yim ntawm lub khob cij los yog daim npav tiv thaiv yog tias txhua yam ua haujlwm raws li nws yuav tsum tau thiab tom qab ntawd tsim cov phiaj xwm tawm ntawm qhov ntawd. Qhov ntawd yog txoj hauv kev yooj yim tshaj plaws kom tsis txhob ua yuam kev tab sis qee zaum nws nyuaj rau cov qauv vim tias cov khoom me me uas tau teeb tsa saum npoo.

Kuv siv los ua qauv txhua qhov ntawm kuv cov phiaj xwm tab sis vim tias kuv tab tom siv cov khoom me me thiab me dua, thiab vim tias kuv tsis muaj sijhawm ntau vim qhov nyiaj ntau ntawm cov phiaj xwm uas kuv tab tom ua kuv tsis ua qauv yuav luag txhua ntawm kuv cov phiaj xwm.

Kauj Ruam 8: Xaus

Tsis txhob liam koj tus kheej rau qhov ua yuam kev ntawd, txhua tus neeg ua yuam kev, ua yuam kev yog muaj los kawm tawm ntawm lawv, qhov ntawd yog qhov zoo. Tsuas yog tsis txhob rov ua koj qhov yuam kev. Sim ua kom zoo dua txhua lub sijhawm!

Kuv vam tias qhov no tau pab rau koj, yog tias koj muaj lus qhia ntxiv tso rau hauv cov lus hauv qab no!

Zoo siab ua!
