1. Xaiv qhov SCH lossis PCB cov ntaub ntawv npe (ua lus Askiv thiab tus lej) thiab ntxiv lub npe txuas ntxiv.
2. Schematic daim duab ua ntej tsim qhov loj me ntawm daim phiaj, qhov loj ntawm daim duab, xaiv cov txheej txheem ntsuas, ntxiv cov tsev qiv ntawv zoo. Kos cov kab kos, cov khoom siv, thiab kab raws li cov txheej txheem ua haujlwm ntawm Circuit hauv txoj hauv kev uas nws yooj yim pom lub hauv paus ntsiab lus. Kom deb li deb tau zoo ib yam, zoo nkauj, tsis txhob taug txoj hlua hlau sab hauv, tiv thaiv kom tsis txhob taug kev hlau nyob nruab nrab ntawm tus pin, vim qhov no tsis muaj hluav taws xob txuas. Nws yog qhov zoo tshaj plaws kom tsis txhob cia ob lub ntsej muag txuas ncaj qha, tom qab kos duab tuaj yeem suav tus lej (tshwj xeeb qhov tshwj xeeb tshwj xeeb), thiab tom qab ntawd ntxiv qhov sib piv tus nqi sib xws, nws yog qhov zoo tshaj los hloov tus nqi nominal rau liab, siab tawv, yog li tuaj yeem ua tau cais los ntawm daim ntawv lo. Tau zoo dua tso daim ntawv lo thiab tus nqi nom tswv hauv txoj haujlwm tsim nyog, sab laug dav yog daim ntawv lo, sab xis yog tus nqi nom tswv, lossis siab dua yog daim ntawv lo, tsis muaj tus nqi qis dua hauv qab no. Cov txheej txheem ntawm kev txuag txuag! Ua ntej, xyuas kom tseeb tias daim duab qhia chaw yog qhov raug, ERC kuaj xyuas qhov ua yuam kev, thiab tom qab ntawd luam daim tshev. Qhov thib ob, nws yog qhov zoo tshaj los xam cov txheej txheem hauv Circuit Court, rau qhov siab thiab qis voltage; Me me tam sim no; Analog, digital; Qhov loj me teeb liab; Qhov loj ntawm lub zog hauv cov thaiv kom yooj yim teeb tsa nyob tom qab.
3. PCB cov tsev qiv ntawv rau cov tsev qiv ntawv txheem thiab lawv cov tsev qiv ntawv ib puag ncig tsis muaj cov ntim khoom ntim khoom, yuav tsum ua tib zoo saib cov duab sab saud, xyuam xim rau qhov loj me, ncoo me me, txoj hauj lwm, tus lej, qhov loj me, kev qhia, (luam ntawv txoj kev zoo ). Lub npe ua lus Askiv, yooj yim pom qhov zoo tshaj plaws, nws yog qhov zoo dua los qhia qhov loj me sib xws, yog li ntawd lub sijhawm tom ntej kom pom (tuaj yeem siv lub npe thiab qhov loj me ntawm daim ntawv teev tseg). Rau cov diode ntau, triode yuav tsum tau them sai sai rau qhov qhia tawm ntawm daim ntawv lo, nws yog qhov zoo tshaj kom muaj cov kab sib txawv ntawm cov diode, pob triode hauv lawv tus kheej lub tsev qiv ntawv, xws li 9011-9018, 1815, D880, thiab lwm yam .. Lub teeb-emitting diode (LED), RAD0.1, Rb.1 /.2, thiab lwm yam khoom siv uas tsis nyob hauv lub tsev qiv ntawv txheem yuav tsum tau ntim rau hauv lawv lub tsev qiv ntawv. Paub nrog daim ntawv foob ntawm cov khoom siv sib xws (resistors, capacitors, diodes, triodes).

4. Tsim cov rooj sib tham hauv cov kab kos duab sab hauv ntxiv pob, txuag, ERC tshawb xyuas, tsim cov npe tshuaj xyuas. Tsim cov ntxhuav network.
5. Teeb tsa PCB, xaiv cov txheej txheem ntsuas, ntes thiab pom qhov loj ntawm daim phiaj, tsim txheej sab nrauv raws li qhov yuav tsum tau ua (qhia lossis kos los ntawm koj tus kheej), thiab tom qab ntawd tso txoj haujlwm ntawm qhov kho qhov, qhov loj me ( 3.0mm ntsia hlau tuaj yeem siv 3.5mm sab hauv lub ncoo, 2.5 ntsia hlau tuaj yeem siv 3 lub qhov sab hauv), ntug ntawm lub ncoo, qhov loj me, qhov chaw ruaj khov.
Ntxiv cov tsev qiv ntawv koj xav tau.
6. Layout hu rau lub rooj sib tham, hu rau hauv cov khoom, hloov kho ib feem ntawm qhov loj me ntawm lub ncoo, teeb tsa txoj cai thaiv, tuaj yeem hloov qhov loj ntawm daim ntawv lo, tuab, zais tus nqi nominal. Tom qab ntawd tso thiab xauv cov khoom uas xav tau txoj haujlwm tshwj xeeb ua ntej. Tom qab ntawd raws li cov txheej txheem teeb tsa kev ua haujlwm, (SCH tuaj yeem siv rau hauv kev xaiv hloov pauv mus rau PCB xaiv), feem ntau tsis siv X, Y rau kev thim rov qab tivthaiv, tabsis nrog kev hloov chaw, lossis L qhov tseem ceeb, (vim qee yam tsis tuaj yeem ua tau yuav thim rov qab, xws li kev sib koom ua ke, sib txuas, thiab lwm yam). Rau qhov ua haujlwm tau zoo tso thawj qhov chaw nruab nrab, lossis cov khoom siv, thiab tom qab ntawd muab tso rau sab ntawm cov khoom me me, (xws li kev sib xyaw ua ke tau muab tso ua ntej, thiab tom qab ntawd tso ncaj qha thiab sib xyaw thaiv ob tus pin ncaj qha txuas cov khoom sib txuas, muab tso ua ke thiab thaiv tus pin txuas cov khoom sib txuas, thiab cov khoom sib xws ua ke, kom deb li deb tau zoo nkauj dua kuj xav txiav txim siab qhov yooj yim ntawm tom qab qhov txuas). Tau kawg, qee qhov tshwj xeeb yuav tsum tau muab tso ua ntej, xws li qee lub lim dej lim dej thiab siv lead ua oscillators yuav tsum tau muab tso ze rau qee yam khoom ua ntej. Thiab cov khoom uas cuam tshuam nrog txhua yam thiab nyob deb ntawm nws. Cov qauv hluav taws xob siab thiab qis yuav tsum raug cais los ntawm ntau dua 6.4mm. Ua tib zoo saib xyuas qhov chaw tso cua sov, cov khoom sib txuas thiab kho qhov muag. FILL tuaj yeem siv tau rau hauv qhov chaw uas tsis tuaj yeem ua haujlwm txuas. Kuj xav txog cov cua sov, cov khoom siv cua sov.

Resistor thiab diode kev tso kawm: muab faib ua kab rov tav thiab ntsug:
1) Tiaj tiaj: thaum cov naj npawb ntawm cov khoom siv hluav taws xob tsis ntau, thiab qhov loj ntawm lub rooj tsav xwm hauv Circuit Court loj, feem ntau nws zoo dua los siv tiaj; Rau kev tiv thaiv qis dua 1/4W tiaj tus, qhov nrug nruab nrab ntawm ob lub pawm no feem ntau yog 4/10 ntiv tes, thiab rau kev tiv thaiv ntawm 1/2W tiaj tus, qhov nrug nruab nrab ntawm ob lub pawm no feem ntau yog 5/10 ntiv tes; Diode tiaj tus, 1N400X series rectifier, feem ntau siv 3/10 nti; 1N540X series rectifier raj, feem ntau siv 4 ~ 5/10 ntiv tes.
2) ntsug: thaum cov naj npawb ntawm cov khoom siv hluav taws xob ntau dua, thiab qhov loj ntawm lub rooj tsav xwm hauv Circuit Court tsis loj, kev siv dav dav, ntsug thaum qhov nrug nruab nrab ntawm ob lub pawm feem ntau siv li 1 txog 2/10 ntiv tes.
7. Cov xov hlau: xub teeb tsa cov ntsiab lus hauv cov cai, VCC, GND lub zog thiab lwm cov kab loj tam sim no tuaj yeem teeb tsa qhov dav (0.5mm-1.5mm), feem ntau 1mm tuaj yeem hla 1A tam sim no. Rau cov kab hluav taws xob loj sib nrug tuaj yeem teeb tsa mus rau qhov loj, feem ntau 1 hli yog 1000V. Teeb, thawj daim ntaub VCC, GND thiab lwm yam kab tseem ceeb. Nco ntsoov qhov sib txawv ntawm cov qauv. Nws yog qhov zoo tshaj los ntxiv qee kab rau hauv ib lub vaj huam sib luag. Lub qhov yuav tsis yog kab rov tav lossis ntsug. Feem ntau, tsis muaj xov hlau ntawm cov kab laug sab laug ntawm cov khoom sib txuas. Cov xov hlau dav uas muaj qhov siab tam sim no tuaj yeem kos rau ntawm txheej txheej kom cov tin tuaj yeem ntxiv tom qab. Siv lub kaum sab xis 45 degree rau txuas.
8. Hloov kho kab ntawv tus kheej: hloov kho qhov dav ntawm qee txoj kab, kaum, rhuav thaj lossis txuas vuam (ib lub vaj huam sib luag yuav tsum tau ua), tso tooj liab, cuam tshuam nrog xaim av.
9. Txheeb xyuas DRC, EMC, thiab lwm yam, thiab tom qab ntawd koj tuaj yeem luam daim tshev, sib piv cov lus sib tham hauv network. Txheeb xyuas daim ntawv teev npe.
10. Ntxiv cov qauv (feem ntau hauv qhov screen rau hauv).
11. Feem ntau lub zog ntsuas hluav taws xob tau hloov kho raws lub moos kom nce (qhov hluav taws xob, tam sim no, thiab lwm yam).
12. Cov zaus ntau (> 20MHz) feem ntau yog sib npaug hauv av. <10MHz lossis <1MHz ib qho taw tes hauv av. Hauv nruab nrab yog sib xyaw av.
13. Raws li qhov xav tau, tsis yog txhua lub cuab yeej yuav tsum tau ntim rau hauv cov txheej txheem, uas tuaj yeem sib txuas lossis txuas ncaj qha.
14. Thaum txuas lub pawg thawj coj saib luam tawm, txoj haujlwm ntawm cov khoom siv ntawm lub rooj tsavxwm yuav tsum txiav txim siab ua ntej, thiab tom qab ntawd cov xaim av thiab kab hluav taws xob yuav tsum tau tso. Thaum npaj cov kab hluav taws xob ceev cov kab hluav taws xob, nws yog qhov zoo tshaj los txiav txim siab cov kab hluav taws xob qis. Txoj haujlwm ntawm cov khoom siv tau muab faib ua pawg raws li lub zog siv hluav taws xob, simulation digital, nrawm, tam sim no thiab lwm yam. Hauv qhov xwm txheej nyab xeeb, lub hwj huam qaum yuav tsum nyob ze rau hauv av kom ntau li ntau tau. Txo thaj tsam ntawm qhov sib txawv ntawm hluav taws xob kuj tseem pab txo kev cuam tshuam ntawm Circuit Court. Thaum nrawm, nruab nrab thiab qis qis logic circuits yuav tsum tau muab tso rau ntawm lub rooj sib tham hauv Circuit Court, qhov kev kub ceev logic circuits yuav tsum tau muab tso ze rau ntawm ntug ntawm qhov txuas, thiab qhov qis qis logic thiab nco circuits yuav tsum muab tso kom deb ntawm qhov txuas. Qhov no muaj txiaj ntsig zoo rau kev txo qis ntawm kev sib txuas tsis sib xws, hluav taws xob thiab cuam tshuam. Av yog qhov tseem ceeb tshaj plaws. Txog lub sijhawm kom muaj thaub qab, lossis qee cov kauj ruam yooj yim kom tsoo, cov ntaub ntawv puas rau thaub qab.
