tsebisa
Boto ea potoloho e hatisitsoeng (PCB) ke mokokotlo oa lisebelisoa tsa elektroniki, e fanang ka sethala sa ho hokahanya le ho ts'ehetsa likarolo tse fapaneng tsa elektroniki.Ho etsa PCB ho ka bonahala ho le boima, haholo ho ba qalang, empa ka tsebo e nepahetseng le katamelo, e ka ba ts'ebetso e thabisang le e khotsofatsang.Ho blog ena, re tla u tsamaisa ka mehato ea mantlha le mehopolo ea ho theha PCB ea hau ka katleho ho tloha qalong.
1. Utloisisa litlhoko tsa moralo
Pele o kena leetong la moralo oa PCB, ho bohlokoa ho hlalosa hantle litlhoko tsa projeke.Etsa qeto ea morero oa boto, tšebeliso e reriloeng, le likarolo tse khethehileng tseo e li hlokang ho haha.Tseba lintlha tsa motlakase, litšitiso tsa boholo bo hlokahalang, le likarolo life kapa life tse ikhethileng tse hlokahalang.
2. Sekeha le ho rera moralo
Ho theha moralo ke qalo ea moralo ofe kapa ofe oa PCB.U sebelisa lisebelisoa tsa software tse kang EAGLE, KiCAD kapa Altium, u ka fetola mehopolo ea hau hore e be litšoantšo tse schematic.Sena se kenyelletsa ho hokahanya likarolo tsa elektronike, ho tsamaisa tsela ea lipontšo tsa motlakase.
Ka mor'a moo, sebopeho sa 'mele sa PCB se tlameha ho reroa.Nahana ka lintlha tse kang ho beoa ha likaroloana, ho fetisoa ha lets'oao, ho beha phepelo ea motlakase, le lifofane tsa fatše.Etsa bonnete ba hore moralo o lumellana le melao ea moralo oa indasteri le mekhoa e metle ho qoba tšitiso ea matšoao kapa lerata.
3. Khetho ea likarolo le ho beha
Ho khetha likarolo tse nepahetseng bakeng sa PCB ho bohlokoa ts'ebetsong le ts'ebetsong ea eona.Nahana ka lintlha tse kang tekanyo ea motlakase, litlhoko tsa hona joale, le ho lumellana le likarolo tse ling.Batlisisa le ho fumana lisebelisoa tsa boleng bo holimo ho tsoa ho bafani ba thepa ba tsebahalang.
Ho beha likarolo hantle ho bohlokoa ho netefatsa moralo o hlophisitsoeng le o kopaneng oa PCB.Beha likarolo ka mokhoa o hlophisehileng ha u ntse u nahana ka phallo ea lets'oao, litlhoko tsa motlakase le lintlha tsa mocheso.Hape ke habohlokoa ho lumella tumello e lekaneng pakeng tsa likarolo ho qoba tšitiso leha e le efe nakong ea ho kopanya kapa ho kopanya boto.
4. Routing ea mesaletsa PCB
Trace routing e bolela mokhoa oa ho theha litsela tsa koporo tse hokahanyang likarolo tse fapaneng ho PCB.Lipontšo, matla le mesaletsa ea fatše li tlameha ho hlophisoa ka hloko.Latela sebopeho se nang le lera ho arola mats'oao a lebelo le phahameng ho tloha ho mats'oao a lerata kapa a matla a holimo.
Lintlha tse kang bophara ba trace, bolelele ba ho bapisa, le taolo ea impedance li phetha karolo ea bohlokoa ho botšepehi ba pontšo le ho tiea.Etsa bonnete ba hore u latela melao ea moralo le litataiso tse fanoeng ke lisebelisoa tsa software ho qoba mathata leha e le afe a ka bang teng nakong ea ts'ebetso ea tlhahiso.
5. Melao le Tlhophiso ea Moqapi
Ka mor'a hore mokhoa oa ho tsamaisa o phethe, ho bohlokoa ho netefatsa moralo pele o o phethela.Etsa tlhahlobo ea melao ea moralo (DRC) ho bona liphoso tse ka bang teng kapa tlolo ea molao.Mohato ona o tiisa hore moralo o lumellana le lithibelo tsa tlhahiso le litlhaloso.
6. Rekota le ho hlahisa litokomane tsa tlhahiso
Ho ngola ka nepo moralo oa PCB ho bohlokoa bakeng sa tšebeliso ea nako e tlang le ho lokisa liphoso.Hlahisa lifaele tse hlokahalang tsa tlhahiso, ho kenyelletsa lifaele tsa Gerber, lifaele tsa drill, le Bill of Materials (BOM).Lekola lifaele habeli ho etsa bonnete ba hore li emela moralo oa hau ka nepo.
ha re phethela
Ho iketsetsa PCB ea hau ho tloha qalong ho ka 'na ha bonahala e le mosebetsi o boima qalong, empa ka mamello, boikoetliso le mokhoa o nepahetseng, e ka fetoha phihlelo e monate.Ka ho utloisisa litlhoko tsa moralo, ho rera moralo ka hloko, ho khetha likarolo tse nepahetseng, ho tsamaisa ka nepo, le ho netefatsa netefatso ea moralo, o ka theha li-PCB tse sebetsang le tse tšepahalang.Joale ke hobane'ng ha u emetse?Ikakhele ka setotsoana lefatšeng la moralo oa PCB 'me u ntlafatse merero ea hau ea elektroniki!
