Maitiro ekushandura dhayagiramu yedunhu kuita inoshanda yakadhindwa yedunhu bhodhi (PCB) marongero anogona kuve basa rakaoma, kunyanya kune vanotanga mune zvemagetsi.Nekudaro, neruzivo rwakakwana uye maturusi, kugadzira PCB dhizaini kubva kune schematic inogona kuve inonakidza uye inopa mubayiro chiitiko.Mune ino blog, isu tichaongorora matanho anobatanidzwa mukugadzira PCB dhizaini kubva kudhiyagiramu yedunhu, ichikupa iwe ruzivo rwakakosha kuti ugone hunyanzvi hwePCB dhizaini.
Danho 1: Ziva Dhiyagiramu Yedunhu
Kunyatsonzwisisa kwedhiyagiramu yedunhu kwakakosha usati wanyura muPCB dhizaini dhizaini.Ziva zvikamu, zvibatanidzo zvazvo, uye chero chakananga chinodiwa padhizaini.Izvi zvinokugonesa kuronga uye kuita marongero nemazvo.
Danho 2: Kutapurirana Circuit Diagram
Kuti utange dhizaini yedhizaini, unofanirwa kuendesa schematic kune yako PCB dhizaini software.Kune akasiyana siyana esoftware sarudzo pamusika, zvese zvemahara uye zvakabhadharwa, zvine madhigirii akasiyana ehunyoro.Sarudza iyo inokodzera zvaunoda uye hunyanzvi.
Danho 3: Component Placement
Nhanho inotevera ndeyekuisa zvikamu paPCB marongerwo.Zvinhu zvakati wandei zvinotariswa kana uchiisa kunze zvikamu, senge nzira dzechiratidzo, kubatanidza magetsi, uye zvipingaidzo zvemuviri.Ronga dhizaini yako nenzira inovimbisa kukanganisa kushoma uye kuita kwakaringana.

Mushure mekuisa zvikamu, nhanho inotevera yakakosha ndeye nzira.Maronda inzira dzemhangura dzinobatanidza zvikamu paPCB.Rongedza masaini akakosha kutanga, senge yakakwira frequency kana mitsetse inonzwisa tsitsi.Shandisa maitiro ekugadzira akakodzera, akadai sekudzivirira makona akapinza uye kuyambuka nhanho, kuderedza crosstalk uye kukanganisa.
Nhanho 5: Ground uye Power Planes
Batanidza yakakodzera pasi uye ndege dzemagetsi muPCB dhizaini dhizaini.Iyo ndege yepasi inopa yakaderera-inopikisa kudzoka nzira yemazuva ano, inoderedza ruzha uye inovandudza chiratidzo chekuvimbika.Saizvozvo, ndege dzemagetsi dzinobatsira kugovera simba zvakaenzana pabhodhi, kuderedza kudonha kwevoltage uye kuwedzera kushanda zvakanaka.
Nhanho 6: Dhizaini Rule Tarisa (DRC)
Mushure mekugadzirisa kwapera, Dhizaini Rule Cheki (DRC) inofanira kuitwa.DRC inotarisa dhizaini yako ichipesana nemirau yakafanotaurwa uye zvakatemwa, kuve nechokwadi chekuti dhizaini inosangana nezvinodiwa.Iva neruzivo rwekucheneswa, kuteedzera upamhi, uye mamwe magadzirirwo maparamita panguva iyi.
Danho rechinomwe: Gadzira Manufacturing Files
Mushure mekubudirira kupfuudza DRC, mafaira ekugadzira anogona kugadzirwa.Aya mafaira anosanganisira mafaira eGerber uye Bill of Materials (BOM), iyo ine data inodiwa pakugadzirwa kwePCB, inonyora zvinhu zvose zvinodiwa pamusangano wegungano.Ita shuwa kuti zvinyorwa zvekugadzira ndezvechokwadi uye zvinoenderana nezvinodiwa nemugadziri.
mukupedzisa:
Kugadzira dhizaini yePCB kubva pachirongwa kunosanganisira nzira yakarongeka kubva pakunzwisisa dunhu kusvika pakugadzira zvinyorwa zvekugadzira.Nhanho yega yega mukuita inoda kutarisisa kune zvakadzama uye kuronga kwakaringana.Nekutevera matanho aya uye kutora mukana wezvishandiso uye software iripo, unogona kugona hunyanzvi hwePCB dhizaini dhizaini uye kuunza schematics yako kuhupenyu.Saka simudza maoko ako uye rega hunyanzvi hwako uye hunyanzvi hwehunyanzvi hufambe munyika yePCB dhizaini!
