Umdwebo wohlelo lwe-PCB

Ngokusekelwe kuzidingo zakho zedizayini, masidale umdwebo wohlelo.

Iyini i-PCB Schematic Diagrams

Imidwebo eyisikimu isebenza njengepulani lokuklama nokukhiqiza amasekethe kagesi. I-PCB Schematic Diagram iwumfanekiso oyisithombe wesekethe ye-elekthronikhi, ebonisa ukuhlelwa kwezingxenye nokuxhumana. Banikeza umhlahlandlela obonakalayo wonjiniyela, okubavumela ukuthi baqonde futhi basebenze ngamasekethe ayinkimbinkimbi.

I-Schematic Diagram vs. PCB Isakhiwo

I-PCB-Schematic-Diagrams

Umdwebo weSchematic

Igxile ekuxhumaneni okunengqondo phakathi kwezingxenye.

PCB-Isakhiwo

Isakhiwo se-PCB

Isebenzisana nokuhlelwa kwezakhi ebhodini langempela.

Ngena ngokubaluleka kwemidwebo yohlelo:

Imidwebo eyisikimu isebenza njengokumelela okubonakalayo kwamasekhethi kagesi ayinkimbinkimbi. Benza kube lula ukuqonda ukusebenza kwesekethe, okwenza kube lula konjiniyela, abaklami, nochwepheshe ukubamba ukuxhumana phakathi kwezingxenye ezihlukahlukene.
Ngaphezu kwalokho, ama-schematics angamathuluzi ayigugu okuxilonga nokulungisa izinkinga kumasekhethi kagesi. Uma umjikelezo ungasebenzi kahle, onjiniyela bangabhekisa kuhlelo ukuze bakhombe umthombo wenkinga ngokushesha. Lokhu kusheshisa inqubo yokulungisa iphutha, kunciphisa isikhathi sokuphumula nezindleko.

Uwakha Kanjani Imidwebo Ehlelekile

Thola lesisho

Khetha Isofthiwe Elungile

Khetha isofthiwe yokuklama ye-PCB evumelana nezidingo zakho. Ezinye izinketho ezidumile zifaka uKhozi, umklami we-Altium, i-KiCad, i-OrCAD, ne-EasyEDA. Lawa mathuluzi anikezela ngamalabhulali ezingxenye nezici zokuthwebula isikimu.

Ingqungquthela Yokuqanjwa Kwekhasi

Misa umhlangano wokuqamba amagama ocacile wamakhasi akho esikimu ukuze ulondoloze ukuhleleka nokucaca. Isibonelo esilandelayo:
A_Block Umdwebo
I-B_Power Supply
C_MCU Interface
D_Memory Interface
E_Umlando Wokubuyekeza

Ukusetha Igridi

Lungiselela izilungiselelo zegridi kusofthiwe yakho yokuklama. Sebenzisa igridi eqondana nosayizi bezingxenye zakho kanye nesikhala sephini ukuze ubeke kahle.

Ukuvimbela Isihloko Sekhasi

Bandakanya ibhulokhi yesihloko ekhasini ngalinye lohlelo ngolwazi olubalulekile njengegama lephrojekthi, idethi, igama likanjiniyela, nenombolo yokubuyekeza.

Amanothi/Amazwana:

Engeza amazwana noma amanothi njengoba kudingeka ukuze uchaze izinqumo ezibucayi zedizayini, okucatshangwayo, noma ulwazi olubalulekile.

Umlando Wokubukeza

Gcina umlando wokubuyekeza emakhasini esikimu, obonisa izinguquko, izinsuku, nabantu abanomthwalo wemfanelo.

Umdwebo weBlock

Uma uhlelo lwakho lusebenzisa amakhasi amaningi, dala ithebula lokuqukethwe ukuze usize abasebenzisi bazulazule kudokhumenti kahle.

I-Hierarchical Schematic Design

Hlela isikimu sakho ngokohlelo uma umklamo uyinkimbinkimbi. Ihlukanise ibe izigaba ezilawulekayo noma amamojula ukuze kucace.

Ireferensi Yengxenye

Nikeza amareferensi ahlukile engxenyeni ngayinye (isb, i-U1 yama-IC, i-R1 yezinto eziphikisayo) futhi ngokuqhubekayo uzilebule kuhlelo.

Isizukulwane Sophawu

Dala noma sebenzisa izimpawu ezichazwe ngaphambilini zezingxenye. Qinisekisa ukuthi izimpawu zimelela ngokunembile izingxenye zangempela ekwakhiweni.

Net Connections

Dweba imigqa (amanetha) amaphinikhodi axhumayo amele ukuxhumana kukagesi. Sebenzisa imibala engaguquki noma izitayela zezinhlobo zamasignali ezihlukene.

Hlola I-DRC (Ukuhlola Umthetho Womklamo)

Yenza ukuhlola kwe-DRC ukuze uhlonze futhi ulungise ukwephulwa kwemithetho yedizayini, njengokusula okungafanele noma amanethi angaxhumekile.

Ungayiguqula kanjani i-PCB ibe Umdwebo weSchematic

Onjiniyela bavame ukubhekana nezinselele uma kuziwa ekutholeni imidwebo edingekayo yokulungisa imikhiqizo emidala ye-elekthronikhi. Ukudweba imidwebo yesekethe kuba semqoka ekuhlaziyeni nasekuthuthukisweni komkhiqizo, futhi le nqubo ibandakanya izinyathelo ezibalulekile ezimbalwa:

1

Ukukhetha Izingxenye Ezibalulekile

Qala ngokukhetha ngokucophelela amasekhethi ahlanganisiwe, ama-transformer, ama-transistors, nezinye izinto ezibalulekile zikagesi, ikakhulukazi lezo ezinamaphinikhodi amaningi, njengoba zidlala indima ebalulekile kule nqubo.

2

Ukukhetha Izingxenye Ezibalulekile

Uma i-PCB inezinombolo ze-elementi ezimakiwe, lezi zinombolo ezilandelanayo zilandela imithetho ethile. Sebenzisa lolu hlelo lwezinombolo njengendawo eyinkomba lapho udweba isakhiwo se-PCB.

3

Ukufaka izinombolo mathupha

Ezimweni lapho izinombolo ze-serial zingekho ebhodini eliphrintiwe, kuba kudingekile ukunikeza izinombolo ngesandla. Lokhu kusiza imisebenzi yokuhlola nokuhlela.

4

Izinhlobo Zezintambo Ezihlukanisayo

Hlukanisa kahle izintambo eziphansi, amandla, nezimpawu ebhodini eliphrintiwe.

5

I-Interleaved Wiring

Ukuze ugweme ukuminyana, izintambo zomdwebo wesifunda zivame ukuhlukana, okuholela ekubukeni okuyinkimbinkimbi. Ungakwenza lokhu kube lula ngokusebenzisa amamaki wetheminali kanye nezimpawu zokubeka phansi ukuze uthole ugesi kanye nezintambo eziphansi. Kumasekhethi anezingxenye eziningi, cabanga ngokudweba amasekhethi amayunithi ngokwehlukana bese uwahlanganisa.

6

Amathuluzi Okudweba

Lapho udweba, khetha iphepha lokulandela elikhanyayo namapeni ombala ukuze kucace. Hlukanisa izingxenye ezinemibala (isb., izintambo eziphansi, izintambo zikagesi, izintambo zesignali) ukuze uthole ukubonwa okubonakalayo okulula nokuhlaziywa kwesekethe ngokushesha.

7

Mastering Unit Circuits

Abaklami kufanele babe nobungcweti bezakhi zesekethe yeyunithi kanye namasu okudweba akudala, njengamabhuloho alungisa kabusha, amasekhethi okuqinisa amandla kagesi, ama-amplifiers okusebenza, namasekhethi adidiyelwe edijithali.

8

Imidwebo Yesekhethi eyinkomba

Lapho udweba umdwebo wesifunda, funa imidwebo yesifunda emikhiqizweni efanayo ukuze uthole ireferensi. Lo mkhuba ungahlehlisa kakhulu inqubo yokudweba, iyenze isebenze kahle.
