1. Siv txoj hauv kev zoo hauv av (Source: Electronic Enthusiast Network)

Xyuas kom meej tias tus tsim muaj txaus bypass capacitors thiab cov dav hlau hauv av. Thaum siv ib qho kev sib xyaw ua ke, nco ntsoov siv lub tshuab hluav taws xob tsim nyog nyob ze ntawm lub tshuab hluav taws xob rau hauv av (zoo dua lub dav hlau hauv av). Lub peev xwm tsim nyog ntawm lub capacitor yog nyob ntawm daim ntawv thov tshwj xeeb, capacitor technology thiab kev khiav hauj lwm zaus. Thaum lub bypass capacitor muab tso rau nruab nrab ntawm lub hwj chim thiab hauv av pins thiab muab tso ze rau qhov tseeb IC tus pin, lub electromagnetic compatibility thiab susceptibility ntawm lub Circuit Court yuav optimized.

2. faib cov khoom ntim khoom siv virtual

Sau ib daim nqi ntawm cov ntaub ntawv (bom) los xyuas cov khoom siv virtual. Cov khoom siv virtual tsis muaj kev cuam tshuam nrog ntim thiab yuav tsis raug xa mus rau theem layout. Tsim ib daim nqi ntawm cov ntaub ntawv, thiab tom qab ntawd saib tag nrho cov khoom siv virtual hauv kev tsim. Cov khoom nkaus xwb yuav tsum yog lub zog thiab cov teeb liab hauv av, vim tias lawv suav tias yog cov khoom siv virtual, uas tsuas yog ua tiav hauv qhov chaw schematic thiab yuav tsis raug xa mus rau qhov tsim qauv. Tshwj tsis yog siv rau lub hom phiaj simulation, cov khoom siv tso tawm hauv qhov virtual yuav tsum tau hloov nrog cov khoom siv encapsulated.

3. Nco ntsoov tias koj muaj cov ntaub ntawv teev cov ntaub ntawv tiav

Xyuas seb puas muaj cov ntaub ntawv txaus nyob rau hauv daim ntawv tshaj tawm cov ntaub ntawv. Tom qab tsim daim ntawv tshaj tawm cov ntaub ntawv, nws yuav tsum ua tib zoo xyuas thiab ua kom tiav cov khoom tsis tiav, tus neeg muag khoom lossis cov chaw tsim khoom cov ntaub ntawv hauv txhua qhov khoom nkag.

4. Cais raws li daim ntawv lo

Txhawm rau ua kom yooj yim rau kev txheeb xyuas thiab saib ntawm daim nqi ntawm cov ntaub ntawv, xyuas kom meej tias cov khoom siv sib txuas ua ke.

5. Tshawb xyuas lub rooj vag ntau dhau

Feem ntau hais lus, cov khoom nkag ntawm txhua lub rooj vag rov qab yuav tsum muaj cov teeb liab sib txuas kom tsis txhob ntab cov khoom siv nkag. Xyuas kom tseeb tias koj tau kuaj xyuas tag nrho cov kev rov ua dua lossis ploj ntawm lub rooj vag circuits, thiab tag nrho cov inputs tsis siv neeg txuas tag nrho. Qee zaum, yog tias lub davhlau ya nyob twg nkag tau raug tshem tawm, tag nrho lub kaw lus tsis tuaj yeem ua haujlwm raug. Siv lub dual op amp uas feem ntau siv hauv kev tsim. Yog tias tsuas yog ib qho ntawm op amps siv nyob rau hauv lub dual op amp IC Cheebtsam, nws raug nquahu kom siv lwm qhov op amp, lossis hauv av cov tswv yim ntawm op amp uas tsis siv, thiab siv cov kev sib koom ua ke tsim nyog (lossis lwm qhov nce) ) Cov lus tawm tswv yim los xyuas kom meej tias tag nrho cov khoom tuaj yeem ua haujlwm ib txwm.

Qee zaum, ICs nrog cov pins ntab yuav tsis ua haujlwm zoo nyob rau hauv qhov kev qhia tshwj xeeb. Feem ntau tsuas yog thaum lub cuab yeej IC lossis lwm lub rooj vag hauv tib lub cuab yeej tsis ua haujlwm hauv lub xeev saturated-thaum cov tswv yim lossis cov zis nyob ze los yog hauv lub zog hluav taws xob ntawm cov khoom siv, IC no tuaj yeem ua tau raws li cov lus qhia thaum nws ua haujlwm. Kev simulation feem ntau tsis tuaj yeem ntes qhov xwm txheej no, vim hais tias tus qauv simulation feem ntau tsis txuas ntau qhov chaw ntawm IC ua ke los ua qauv kev sib txuas ntab ntab.

6. Xav txog kev xaiv cov khoom ntim khoom

Nyob rau hauv tag nrho cov schematic daim duab theem, cov khoom ntim khoom thiab cov qauv av txiav txim siab uas yuav tsum tau ua nyob rau hauv lub layout theem yuav tsum xav txog. Nov yog qee cov lus qhia los xav txog thaum xaiv cov khoom raws li kev ntim khoom.

Nco ntsoov, lub pob suav nrog cov khoom siv hluav taws xob sib txuas thiab cov khoom siv qhov ntev (x, y, thiab z) ntawm cov khoom, uas yog, cov duab ntawm lub cev tivthaiv thiab cov pins uas txuas rau PCB. Thaum xaiv cov khoom, koj yuav tsum xav txog tej yam mounting lossis ntim txwv uas yuav muaj nyob rau saum thiab hauv qab txheej ntawm lub PCB kawg. Qee cov khoom siv (xws li polar capacitors) yuav muaj kev txwv siab hauv lub taub hau, uas yuav tsum tau xav txog hauv cov txheej txheem xaiv cov khoom. Thaum pib ntawm kev tsim, koj tuaj yeem ua ntej kos ib qho yooj yim Circuit Court board thav duab duab, thiab tom qab ntawd muab qee qhov loj lossis cov khoom tseem ceeb (xws li cov khoom sib txuas) uas koj npaj yuav siv. Nyob rau hauv txoj kev no, kev pom kev pom ntawm lub rooj tsav xwm hauv Circuit Court (tsis muaj xov) tuaj yeem pom qhov xav tau thiab nrawm, thiab qhov chaw txheeb ze thiab qhov siab ntawm lub rooj tsav xwm Circuit Court thiab cov khoom tuaj yeem muab qhov tseeb. Qhov no yuav pab xyuas kom meej tias cov khoom tuaj yeem muab tso rau hauv cov ntim khoom zoo (cov khoom yas, chassis, chassis, thiab lwm yam) tom qab lub PCB sib dhos. Hu rau 3D saib ua ntej hom los ntawm cov ntawv qhia zaub mov kom xauj tag nrho lub rooj tsavxwm
