- Ibhodi Lesifunda Eliphrintiwe |Okubalulekile, FR4
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...
- Ukuhlolwa Kokulawulwa Kwe-Impedans kwebhodi le-PCB
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) ...
- Ibhodi Lesifunda Eliphrintiwe|Nge-VS Pad
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...
- Impilo yeshelufu ye-PCB?Isikhathi sokubhaka nezinga lokushisa?
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...
- Isingeniso sokucutshungulwa kwe-plasma kumabhodi e-PCB
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...
- Ungalithola kanjani ibhodi le-PCB elihle?
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 ...
