Litšebeletso tsa Tlhahiso ea Boto ea Potoloho ea Boleng bo Phahameng ba PCB

PCB e thata le PCB e tenyetsehang ke eng?

Sebakeng sa li-PCB, ho na le mefuta e 'meli ea mantlha: li-PCB tse thata le li-PCB tse tenyetsehang, e' ngoe le e 'ngoe e na le litšobotsi le lits'ebetso tse ikhethang. Ho utloisisa phapang pakeng tsa mefuta ena e 'meli ea PCBs ho ka thusa ho fumana khetho e nepahetseng ka ho fetisisa bakeng sa morero o itseng oa elektronike.

Li-PCB tse thata ke mofuta o tloaelehileng oa PCB, o nang le substrate e thata eo hangata e entsoeng ka thepa e kang fiberglass. Li entsoe ka melao e itseng mabapi le boholo ba masoba, bophara ba trace, sebaka ho ea mathōkong a boto, le botenya ka kakaretso. Li-PCB tse thata li etsoa ka mekhoa e kang ho cheka, ho plating, ho etsa litšoantšo, ho fata le ho pata solder. Li-PCB tsena li loketse lisebelisoa tse kholo tsa elektroniki moo boto e tiileng, e sa tenyetseheng e hlokahalang ho tšehetsa likarolo le ho fana ka khanyetso ea mocheso.

Likarolo tsa li-PCB tse thata

Li-PCB tse thata, likarolo tsa bohlokoa tsa elektroniki, li ithorisa ka likarolo tse 'maloa tsa bohlokoa tse li etsang hore e be tsa bohlokoa lits'ebetsong tse fapaneng:

• Mathata: Li-PCB tse thata li thata ka tlhaho, haholo-holo ka lebaka la tšebeliso ea lisebelisoa tse matlafatsang joaloka FR4. Ho thatafala hona ho tiisa botšepehi ba sebopeho sa boto, ho thibela ho khumama kapa ho phunya.
• Thermal botsitso: E 'ngoe ea melemo ea bohlokoa ea li-PCB tse thata ke botsitso ba tsona bo phahameng ba mocheso. Li ka sebetsa ka botšepehi tlas'a maemo a mangata a mocheso ntle le ho senya ts'ebetso kapa botšepehi.
• Botsitso ba Dimensional: Li-PCB tse thata li boloka boholo ba tsona ha nako e ntse e ea, e leng ntho ea bohlokoa bakeng sa ho netefatsa hore likaroloana li lumellana hantle le hore boto e sebetsa kamoo e reretsoeng bophelo bohle ba eona.
• Thepa ea Motlakase ea Insulation: Li-PCB tse thata li fana ka thepa e ntle ea ho kenya motlakase. Sekhahla sena se thibela ho kena-kenana le motlakase ho sa batleheng, ho netefatsa botšepehi le ho tšepahala ha potoloho.
• Mefuta e mengata: Li-PCB tse thata li ka etsoa ka mekhahlelo e mengata, e lumellang meralo e rarahaneng ea potoloho. Kaho ena e nang le mekato e mengata e nolofalletsa ho kopanngoa ha likarolo tse rarahaneng tsa elektronike le mesebetsi ho boto e le 'ngoe.
• Matla a Phahameng a Matla le Ts'ebetso ea Hona Joale: Li-PCB tse thata li khona ho sebetsana le motlakase o phahameng le oa hona joale, ho etsa hore li tšoanelehe bakeng sa mefuta e mengata ea lisebelisoa moo ho hlokahalang ts'ebetso e matla ea motlakase.

Ka kakaretso, motsoako oa ho satalla, botsitso ba mocheso, botsitso ba sebopeho, thepa ea ho kenya motlakase, likhetho tsa meralo e mengata, le matla a holimo a motlakase / a hajoale a ho sebetsana le li-PCB tse thata ho fetoha karolo ea bohlokoa ho lisebelisoa tsa elektroniki tsa sejoale-joale.

Highleap Electronic: Moetsi oa hau oa PCB ea Tšepahalang

Highleap Electronic e eme e le pula-maliboho le moetapele oa lefats'e tlhahisong ea PCB , e fana ka li-PCB tsa boleng bo holimo le tse tšoarellang. Lihlahisoa tsa rona li kenyelletsa li-PCB tse Tiileng, li-PCB tse Fetohang ka Mokhoa o Motle, le li-PCB tse Tiileng, tsohle li entsoe ka ho nepahala le boleng bo holimo. Ka setaele sa rona sa theknoloji e tsoetseng pele, re netefatsa khotsofalo ea bareki.

Lintlha tse thata tsa moralo oa PCB

Ho theha PCB ho kenyelletsa ho nahanisisa ka hloko ha lintlha tse fapaneng ho netefatsa ts'ebetso e nepahetseng, ts'epahalo, le ho etsoa. E 'ngoe ea lintlha tsa bohlokoa ke khetho ea thepa ea motheo, le FR-4 e le khetho e tloaelehileng ka lebaka la ho hanyetsa mocheso o babatsehang le matla a mochine. Lisebelisoa tse ling, joalo ka likoahelo le likarolo tsa mask a solder, le tsona li ka sebelisoa ho ipapisitse le litlhaloso tsa projeke. Ho phaella moo, botenya ba lera la koporo ke taba ea bohlokoa, kaha likarolo tse teteaneng tsa koporo li fana ka ts'ebetso e ntlafetseng empa li theko e boima ebile li thata ho sebetsa.

Karolo e 'ngoe ea bohlokoa ea moralo oa PCB ke khetho ea qetello ea bokaholimo, e amang ho khona ho sotheloa le ho tšepahala ha nako e telele. Liphetho tse tloaelehileng tsa bokaholimo li kenyelletsa HASL, ENIG, OSP, HASL e se nang loto, tin ea ho qoelisoa, le menoana ea khauta e thata. Bophara ba trace le sebaka le tsona ke lintlha tsa bohlokoa, kaha li ama ts'ebetso ea potoloho 'me li tlameha ho etsoa ho latela litlhoko tsa potoloho. Ho feta moo, lintlha tsa mechini tse kang boholo ba boto, masoba a ho kenya, le ho lumellana le moralo oa sekoahelo li lokela ho nahanoa.

Tsamaiso ea mocheso ke karolo e 'ngoe ea bohlokoa ea moralo oa PCB, haholo-holo bakeng sa likarolo tse matla a phahameng. Ho rala PCB ho qhala mocheso hantle ho ka thusa ho netefatsa ho ts'epahala ha eona nako e telele.
