mokhoa oa ho etsa pcb

Rea u amohela ho tataiso ea rona e felletseng ea ho etsa PCB (Boto ea Potoloho e Hatisitsoeng)!Ka poso ena ea blog, re tla u tsamaisa tšebetsong ea ho theha PCB ho tloha qalong, ho fana ka litaelo tsa mohato ka mohato le malebela a thusang tseleng.Hore na u motho ea ratang ho itlosa bolutu, seithuti, kapa motho ea chesehelang lisebelisoa tsa elektroniki, tataiso ena e etselitsoe ho u thusa ho rala le ho iketsetsa li-PCB tsa hau ka katleho.Kahoo, a re hlahlobeng ka botebo!

1. Utloisisa metheo ea moralo oa PCB:
Pele re kena ts'ebetsong ea tlhahiso, ho bohlokoa ho ba le kutloisiso e tiileng ea metheo ea moralo oa PCB.Itloaetse lisebelisoa tse hlokahalang tsa software, joalo ka software ea EDA (Electronic Design Automation), e u nolofalletsang ho theha le ho hlophisa meralo ea potoloho.

2. Moralo oa morero:
Qala ka ho nahana ka potoloho ea hau u sebelisa schematic.Mohato ona oa bohlokoa o u thusa ho rera hore na karolo ka 'ngoe e tla beoa boto hokae.Mokhahlelong ona kaofela, etsa bonnete ba hore moralo o latela mekhoa e metle bakeng sa boemeli bo hlakileng le bo khuts'oane.

3. Etsa moralo oa PCB:
Hang ha moralo o se o lokile, o fetisetsoa ho software ea moralo oa PCB.Likarolo li beoa boto pele, ho hlokomeloa ho li hlophisa hantle bakeng sa ho tsamaisa tsela e nepahetseng.Hopola ho nahana ka lintlha tse kang boholo ba motsoako, khokahanyo, le ho senyeha ha mocheso.

4. Tsela:
Ho tsamaisa ho kenyelletsa ho theha mesaletsa kapa litsela tse tsamaisang ho hokela likarolo tse fapaneng ho PCB.Etsa qeto ka hloko hore na tsela e 'ngoe le e 'ngoe e tsamaea joang, u nahanne ka lintlha tse kang botšepehi ba matšoao, kabo ea matla le lifofane tse fatše.Ela hloko haholo melao ea tumello 'me u netefatse hore meralo ea hau e kopana le mamello e tloaelehileng ea tlhahiso.

5. Netefatso ea moralo:
Moralo oa hau o tlameha ho netefatsoa ka botlalo pele o tsoela pele ka mokhoa oa ho etsa.Etsa Tlhahlobo ea Molao oa Moralo (DRC) 'me u hlahlobe sebopeho sa hau ho tsoa lehlakoreng le leng le le leng.Etsa bonnete ba hore mesaletsa e arohane hantle 'me ha ho na lifupi tse ka bang teng.

6. Mokhoa oa tlhahiso:
Hang ha o khotsofetse ke moralo oa hau oa PCB, ts'ebetso ea tlhahiso e ka qala.Qala ka ho fetisetsa moralo oa hau ho boto e apereng koporo o sebelisa PCB e koahetsoeng esale pele kapa mokhoa oa ho fetisa toner.Etch boto ho tlosa koporo e feteletseng, e siea feela mesaletsa le lipache tse hlokahalang.

7. Ho cheka le ho rala:
U sebelisa kotopo e nyane ea ho phunya, phunya masoba ka hloko libakeng tse khethiloeng ho PCB.Likoti tsena li sebelisetsoa ho kenya likarolo le ho etsa likhokahano tsa motlakase.Ka mor'a ho cheka, likoti li kenngoa ka lesela le tšesaane la lintho tse tsamaisang tse kang koporo ho ntlafatsa conductivity.

8. Likarolo tsa welding:
Joale ke nako ea ho bokella likarolo ho PCB.Solder karolo e 'ngoe le e' ngoe sebakeng sa eona, ho etsa bonnete ba ho tsamaisana hantle le manonyeletso a matle a solder.Ho kgothaletswa ho sebelisa tšepe ea soldering e nang le matla a nepahetseng le mocheso ho sireletsa likarolo le PCB.

9. Liteko le Tharollo ea Mathata:
Ka mor'a hore soldering e phethoe, ho bohlokoa ho hlahloba ts'ebetso ea PCB.Sebelisa multimeter kapa lisebelisoa tsa tlhahlobo tse nepahetseng ho lekola khokahano, maemo a motlakase le liphoso tse ka bang teng.Lokisa mathata leha e le afe a hlahang 'me u etse liphetoho tse hlokahalang kapa u fetole likarolo.

ha re phethela:

Kea u babatsa!U sa tsoa ithuta ho etsa PCB ho tloha qalong.Ka ho latela tataiso ena e felletseng, joale u ka rala, ua iketsetsa le ho kopanya liboto tsa potoloho tse hatisitsoeng.Ho etsa PCB ke ts'ebetso e khahlang empa e le phephetso e hlokang ho ela hloko lintlha, mamello le tsebo ea lisebelisoa tsa elektroniki.Hopola ho etsa liteko le ho amohela mokhoa oa ho ithuta.Ka ho itloaetsa, u tla ba le boitšepo 'me u khone ho theha meralo e rarahaneng ea PCB.Ho etsa PCB e monate!
