Haddii aad adigu samaynayso PCB layout, being prepared may just help you organize and remember important design details. Si kastaba ha ahaatee, haddii nashqadda loo diro qof kale si uu u qaabeeyo, diyaarin la’aantani waxay sababi kartaa dhibaatooyin waaweyn xagga dhammaystirka naqshada.

Aynu eegno waxyaabo ay tahay in laga fiirsado qorshaha si loo fududeeyo beddelka qaababka PCB.

Sida loo beddelo qaabeynta PCB? Xeerka lambarka koowaad: Dukumentiyo nadiif ah

Naqshadeynta wareegga ayaa laga yaabaa inay ka timaaddo qoraalo ku qoran warqadda, ama qaab -dhismeedyada si degdeg ah loogu sawiray sabuuradda, laakiin dabcan kuwani si fiican looma diiwaangeliyo. Many medical institutions are now forcing doctors to electronically file prescriptions instead of writing them down with pen and paper, so patients can read them easily.

Sida ay muhiim u tahay in si sax ah loo akhriyo dawooyinka la qoro, sidaas oo kale ayaa akhrinta macluumaad faahfaahsan iyo tilmaamaha laga helo shaxanka. Naftaada u roonow oo waqti qaado si aad u hubiso in qaab -dhismeedyadu ay yihiin kuwo la akhrin karo.

Waa kuwan talooyin ku saabsan sida saxda ah ee loo sameeyo:

U adeegso shabakadaha si aad isku waafajiso astaamaha, xarriiqiso, oo u habayso qoraalka.

Farta qoraalka iyo ballaca xariiqda waa in ay ahaataa mid weyn oo ku filan in la akhriyo, laakiin ma aha mid aad u weyn oo khalkhal gelinaysa qorshaha.

Don’t crowd symbols and text together; leave some space for them so they can be read accurately.

Ku qor hab -raacyo leh qulqul macquul ah oo macno samaynaya. Looma baahna in qaybo ay ku xayirmaan gobol; waa la xannibi karaa marba haddii aysan dhab ahaan halkaas ka tirsanayn.

Haddii aad abuuri karto dukumiintiyo badan oo la akhrin karo, uma baahnid inaad ka walwasho isticmaalka bogag kale oo ku jira qorshahaaga.

If you give yourself enough time to create easy-to-use documents, you’ll get a lot of benefit from that extra effort during the layout process.

Qaybaha maktabadda ayaa muhiim u ah beddelidda qaababka PCB

Qayb kale oo muhiim ah oo si guul leh loogu beddelo qaab -dhismeedyada qaababka PCB waa hubinta in qaybaha maktabaddu ay yihiin kuwo casri ah oo sax ah. What the symbol represents must be correct. Tan waxaa ka mid ah boodhadh, qoraal, qaabab, iyo sifooyin. Mararka qaarkood dadku waxay u adeegsadaan astaamo jira qaab -dhismeedyo si ay u dhisaan kuwo cusub, ka dibna iska indho -daraan ku -daridda, tirtiridda, ama wax -ka -beddelka qaybo ka mid ah farriintii asalka ahayd. Wanaagsan, waxaa jiri kara jahawareer badan marka nambarka qaybta ee sawirka sawirka uusan u dhigmin nambarka qaybta ee warbixinta lagu sheegay. The worst case scenario is that the symbolic information is completely wrong and leads to a connection error in the schematic or downstream tool, such as the emulator.

Markaad u dhisayso calaamad cusub naqshadayntaada, hubso inaad ku darto dhammaan macluumaadka qaybaha khuseeya sidoo kale. Tan waxaa ku jiri doona aaladda qaabeynta magaca raad -raaca jirka, lambarka qeybta shirkadda, nambarka qeybta alaab -qeybiyaha, macluumaadka qiimaha, iyo xogta jilitaanka. Shirkad kastaa waxay leedahay halbeegyo u gaar ah waxa ay tahay ama aan lagu darin qaybta maktabadda, laakiin haysashada xog aad u badan ayaa ka wanaagsan in aad wax yar haysato. Markaad dhammayso, hubso inaad ku buuxiso qaybta cusub maktabadda qaybaha ku habboon iyo in qaybaha ku jira qaab -dhismeedka la cusboonaysiiyay si loo tixraaco maktabadda saxda ah.

Macluumaadka qorshaynta oo faahfaahsan oo dhammaystiran waa muhiim

Sida aysan macluumaad badan ugu jirin qaybaha maktabadda, isla sidaas ayay u khuseysaa shaxanka. Be careful not to add so much data that the schematic becomes difficult to read, but add enough information to help downstream with layout, testing, and rework. Waa kuwan tusaalooyin ka mid ah macluumaadka khuseeya:

Aqoonsiga aagagga shaqada ee ku -meelgaarka ah (“korontada”, “xakamaynta marawaxadaha”, iwm.).

Tijaabi booska korontada, dhulka ama calaamadaha gaarka ah.

Meelaynta qaybaha go’an sida isku xirayaasha iyo bareesada.

Qaybaha waxaa loo soo ururiyaa si loo aqoonsado meelaha xawaaraha sare leh ama meelaynta xasaasiga ah.

Wareegyo xasaasi ah oo u baahan kara fiiro gaar ah, sida gaashaanka RF.

Meelaha kulul ee walaaca laga qabo.

Shuruudaha wareegga-xawaaraha sare, sida dhererka xarigga cabbirka ama xadhigga xakamaynta xakamaynta.

Lammaane kala duwan.

In addition to the functional information listed above, don’t forget to include all the general schematic document data. Tan waxaa ku jiri doona waxyaabaha ku jira baarka cinwaanka, sida magaca shirkadda, nambarka qaybta, dib -u -eegista, magaca guddiga, taariikhda, iyo macluumaadka xuquuqda daabacaadda. Adiga oo hubinaya inaad hayso xog kugu filan oo ku saabsan qorshaha iyo xogta ugu badan ee suurtogalka ah, laakiin aan ahayn mid aad u culus, waxay kaa caawineysaa inaad hubiso in si guul leh loogu beddelay qaab -dhismeedka qaab -dhismeedka PCB.
