1. Yini iphakethe elithambile le-cob
I-Netizens Ngokucophelela ingathola ukuthi kunento emnyama kwamanye amabhodi wesifunda, ngakho-ke yini le nto? Kungani kubhodi yesekethe? Uyini umphumela? Eqinisweni, lolu uhlobo lwephakeji. Sivame ukuyibiza ngokuthi "iphakethe elithambile". Kuthiwa iphakethe elithambile empeleni lithi "kanzima", futhi impahla yayo ye-epoxy resin. , Sivame ukubona ukuthi indawo etholayo yekhanda elamukelayo nayo yale ndaba, kanti i-IC IC ingaphakathi kwalo. Le nqubo ibizwa ngokuthi "isibopho", futhi sivame ukuyibiza ngokuthi "ukubopha".
Le yinqubo yokubopha isibopho socingo kwinqubo yokukhiqiza ye-Chip. Igama laso lesiNgisi liyi-cob (chip ebhodini), okungukuthi, chip ekuphaketheni ebhodini. Lokhu kungenye yezobuchwepheshe obandayo be-chip. I-chip inamathiselwe nge-epoxy resin. Ifakwe ebhodini lesekethe ye-PCB ephrintiwe, pho kungani amanye amabhodi wesifunda angenalo lolu hlobo lwephakeji, futhi yini izici zalolu hlobo lwephakeji?
2. Izici zephakheji ethambile ye-COB
Lolu hlobo lobuchwepheshe obuthambile bokupaka buvame ukuthola izindleko. Njengoba kuncipha okulula kakhulu kwe-chip, ukuze kuvikeleke i-IC yangaphakathi kusuka kumonakalo, lolu hlobo lokupakisha ngokuvamile ludinga ukubumba kwesikhathi esisodwa, okuvame ukubekwa phezu kwe-foil foil yebhodi le-Copper. Kuyindilinga futhi umbala umnyama. Lolubuchwepheshe bokupakisha lunezinzuzo zezindleko eziphansi, ukonga isikhala, ukukhanya nokuncane, umphumela omuhle wokuyeka ukushisa, kanye nendlela elula yokupakisha. Imibuthano eminingi ehlanganisiwe, ikakhulukazi amasekethe abiza kakhulu, adinga ukuhlanganiswa kule ndlela. I-Chip yesekethe iholwa ngezintambo zensimbi eziningi, bese inikezela kumenzi ukubeka i-chip kwibhodi yesekethe, ulithengisiswe ngomshini, bese ufaka i-glue ukuze uqinise futhi uqinise.
3. Izikhathi zohlelo lokusebenza
Ngoba lolu hlobo lwephakheji lunezici zalo ezihlukile, lubuye lusetshenziswe emibukeni yesekethe ye-elekthronikhi, njengabadlali be-mp3, amakhamera we-elekthronikhi, amakhamera edijithali, amakhamera abiza kakhulu.
Eqinisweni, ukufakwa okuthambile kwe-COB akugcini kuphela kuma-chip, kusetshenziswa kabanzi kuma-LED, anjenge-COB Light Source, okungukuthi ubuchwepheshe obuhlanganisiwe bokukhanya obukhanyayo obunamathiselwe ngqo kwi-mirror yensimbi yensimbi.
