Ibhodi lesifunda eliphrintiwe lakhiwe ngezingqimba zamasekethe e-foil yethusi, futhi ukuxhumana phakathi kwezingqimba ezihlukene zesekethe kuncike kulezi "vias".Lokhu kungenxa yokuthi ukukhiqizwa kwebhodi lesifunda lanamuhla lisebenzisa izimbobo ezibhoboziwe ukuxhuma amasekhethi ahlukene.Phakathi kwezingqimba zesifunda, kufana nesiteshi sokuxhuma somzila wamanzi ongaphansi komhlaba onezingqimba eziningi.Abangane abadlale ividyo ethi "Brother Mary"...
Esivame ukubhekisela kukho ukuthi "FR-4 Fiber Class Material PCB Board" igama lekhodi lebanga lezinto ezingashi.Imele ukucaciswa kwezinto ezibonakalayo okumele i-resin ikwazi ukuzicisha ngokwayo ngemva kokushiswa.Akulona igama eliphathekayo, kodwa uhlobo lwezinto ezibonakalayo.Ibanga lezinto ezibonakalayo, ngakho-ke kunezinhlobo eziningi zezinto zebanga le-FR-4 ezisetshenziswa kumabhodi wesifunda ajwayelekile njengamanje, kodwa...
Ukuhlola kwe-TDR okwamanje kusetshenziswa kakhulu kubakhiqizi bebhodi lesekhethi yebhethri ye-PCB (amabhodi esekethe ephrintiwe) imigqa yesignali nokuhlolwa kokuvinjwa kwedivayisi.Kunezizathu eziningi ezithinta ukunemba kokuhlolwa kwe-TDR, ikakhulukazi ukubonisa, ukulinganisa, ukukhetha ukufunda, njll. Ukuzindla kuzodala ukuphambuka okukhulu kunani lokuhlola lomugqa wesignali we-PCB omfushane, ikakhulukazi uma kusetshenziswa i-TIP (probe) ...
I-Vias ebhodini lesekethe ibizwa ngokuthi i-vias, ehlukaniswe ngemigodi, imigodi eyimpumputhe kanye nezimbobo ezigqitshiwe (i-HDI Circuit Board).Ngokuyinhloko zisetshenziselwa ukuxhuma izintambo ezingqimbeni ezihlukene zenethiwekhi efanayo futhi ngokuvamile azisetshenziswa njengezingxenye ze-soldering;Amaphedi ebhodini lesifunda abizwa ngokuthi ama-pads, ahlukaniswe abe ama-pin pads kanye nama-surface mount pads;amaphinikhodi anezimbobo ze-solder, okuyi...
Isikhathi sokugcina se-PCB, kanye nezinga lokushisa nesikhathi sokusebenzisa ihhavini yezimboni ukubhaka i-PCB konke kulawulwa yimboni.Ithini impilo yeshelufu ye-PCB?Futhi indlela yokunquma isikhathi sokubhaka kanye nezinga lokushisa?1. Ukucaciswa kokulawula kwe-PCB 1. Ukukhumula nokugcinwa kwe-PCB (1) Ibhodi le-PCB lingasetshenziswa ngokuqondile ku-inthanethi phakathi nezinyanga ezi-2 zosuku lokukhiqiza lwebhodi le-PCB elivalwe futhi elingavuliwe...
Ngokufika kweminyaka yolwazi lwedijithali, izimfuneko zokuxhumana okufika phezulu, ukudluliswa kwesivinini esikhulu, kanye nokuba yimfihlo okuphezulu kwezokuxhumana ziya ngokuya ziba phezulu.Njengomkhiqizo osekelayo obalulekile embonini yobuchwepheshe bolwazi lwe-elekthronikhi, i-PCB idinga i-substrate ukuthi ihlangabezane nokusebenza kwe-dielectric engaguquki, into ephansi yokulahlekelwa kwemidiya, izinga lokushisa eliphezulu...
Ukuthuthukiswa okusheshayo kwezimboni zamaselula, ze-electronics, nezokuxhumana kukhuthaze ukukhula okuqhubekayo kanye nokukhula ngokushesha kwemboni yebhodi lesifunda le-PCB.Abantu banezidingo ezengeziwe zenani lezendlalelo, isisindo, ukunemba, izinto zokwakha, imibala, nokuthembeka kwezingxenye.Kodwa-ke, ngenxa yokuncintisana kwentengo yemakethe, izindleko zezinto zebhodi le-PCB nazo zikhuphuka kakhulu ...
Okokuqala, njengebhodi lesifunda eliphrintiwe, i-PCB ihlinzeka ngokuxhumana phakathi kwezingxenye ze-elekthronikhi.Abukho ubuhlobo obuqondile phakathi kombala nokusebenza, futhi umehluko we-pigments akuphazamisi izakhiwo zikagesi.Ukusebenza kwebhodi le-PCB kunqunywa izinto ezifana nezinto ezisetshenzisiwe (inani eliphezulu le-Q), ukwakheka kwezintambo, kanye nezingqimba ezimbalwa ze-t...
Ibhodi lesifunda elinembayo eliphakeme libhekisela ekusetshenzisweni kobubanzi/isikhala somugqa ocolekile, izimbobo ezincane, ububanzi obuncane bendandatho (noma ukungabi nobubanzi bendandatho), kanye nezimbobo ezigqitshiwe nezingaboni ukuze kuzuzwe ukuminyana okuphezulu.Futhi ukunemba okuphezulu kusho ukuthi umphumela "womncane, omncane, omncane, omncane" uzoletha izidingo zokunemba okuphezulu nakanjani, thatha ububanzi bomugqa njengesibonelo: O. 20mm ububanzi bomugqa, ngokuvumelana nemithethonqubo yokukhiqiza i-O. 16...
