Ibhodi le-PCB (i-Printedcircuitboard) iyindikimba esekelayo yezingxenye ze-elekthronikhi kanye nomhlinzeki woxhumano phakathi kwezinto zikagesi nezinto zikagesi.Cishe ingqalasizinda yawo wonke amadivaysi ahlakaniphile.Ngaphezu kwemisebenzi eyisisekelo yokulungisa izakhi ezihlukahlukene ze-elekthronikhi, umsebenzi obaluleke kakhulu ukuhlinzeka ngoxhumano lwezingxenye ze-elekthronikhi ezingenhla.
Yiziphi izingxenye zebhodi le-PCB?
Ibhodi lesifunda le-PCB lakhiwe ngokuyinhloko nge-welding pad, ngokusebenzisa imbobo, imbobo yokufaka, ucingo, izingxenye, izixhumi, ukugcwalisa, umngcele kagesi nokunye.
(1) Iphedi: imbobo yensimbi esetshenziselwa ukushisela izikhonkwane zezingxenye.
(2) Ngezimbobo: kukhona insimbi ngokusebenzisa izimbobo kanye non-metal ngokusebenzisa izimbobo, lapho insimbi ngokusebenzisa izimbobo kusetshenziswa ukuxhuma izikhonkwane izingxenye phakathi ungqimba ngalunye.
(3) Imbobo yokufaka: esetshenziselwa ukulungisa ibhodi lesifunda.
(4) I-Conductor: ifilimu yethusi yenethiwekhi kagesi esetshenziselwa ukuxhuma izikhonkwane zezingxenye.
(5) Izixhumi: izingxenye ezisetshenziselwa ukuxhuma amabhodi wesifunda.
(6) Ukugcwalisa: isicelo sethusi senethiwekhi yocingo lomhlabathi singanciphisa ngempumelelo i-impedance.
(7) Umngcele kagesi: osetshenziselwa ukunquma ubukhulu bebhodi lesifunda, izingxenye zebhodi azikwazi ukudlula umngcele.
Ibhodi lesifunda le-PCB ngokwesakhiwo lingahlukaniswa libe iphaneli elilodwa le-PCB, iphaneli ye-PCB ephindwe kabili, ibhodi le-multilayer le-PCB;Ibhodi le-multilayer evamile ine, ibhodi lesendlalelo eziyisithupha, ibhodi le-multilayer pcb eliyinkimbinkimbi lingafinyelela izingqimba ezingaphezu kweshumi.
Izingqimba ezengeziwe zamabhodi e-PCB, ukusebenza kukagesi kuzinzile futhi kuthembekile, futhi kuyanda izindleko.Umehluko wezindleko zamaphaneli angashadile nakabili awumkhulu.Uma kungekho sidingo esikhethekile, zonke izimboni zizokhetha ngokukhetha amaphaneli aphindwe kabili.Phela, ukusebenza nokuzinza kwephaneli ekabili kungcono kunephaneli eyodwa.
Ngo PCB multilayer ibhodi, manje imboni esetshenziswa kakhulu noma ezine, ibhodi ungqimba eziyisithupha, umthengi electronics imboni nge ephakeme ibhodi pcb ibhodi ingaphezulu.Nakuba amaphaneli ezendlalelo eziningi anezinzuzo eziningi kunamaphaneli akabili ekusebenzeni, ukuzinza, umsindo nezinye izici, amabhizinisi amaningi nonjiniyela basancamela amaphaneli akabili ukuze kucatshangelwe izindleko.
Njengoba amadivaysi ahlakaniphile eba nzima nakakhulu, izinsiza ezengeziwe ziyadingeka, okuholela ekuhlanganiseni kwesekhethi kanye nezinsiza ezengeziwe ku-PCB.Ngesikhathi esifanayo, izidingo zekhwalithi zezixhumi eziphezulu zamanje zebhodi le-PCB nazo ziyathuthukiswa.Ibhodi elincane le-PCB alikwazi ukunciphisa izindleko kuphela, kodwa futhi lingenza kube lula ukuklama kwebhodi le-PCB, ukuze ukulahlekelwa kwesignali yokudlulisa wesifunda kuncane.
I-Amass high-current PCB board connector ingusayizi wequpha kuphela, futhi umqhubi wokuxhumana uyisiliva egcwele ithusi elibomvu, okuthuthukisa kakhulu ukusebenza kwamanje kokuthwala kwesixhumi.Ngisho nosayizi omncane ungaba nokuthwala okuphezulu kwamanje, ukuqinisekisa ukuthi isifunda sisebenza kahle, futhi izindlela zokufaka ezihlukene zingahlangabezana nezidingo zokufaka zamakhasimende ahlukene ebhodi le-PCB.
I-Amass inobude obuhlukene bezixhumi zamabhodi esekethe e-PCB anogqinsi oluhlukahlukene, oluhambisana nezinga lemboni logqinsi lwephaneli eveziwe engu-1.0-1.6mm ukuze kuqinisekiswe ukusetshenziswa okuvamile kwemishini!
