Kusho Ukupakisha I-COB? Uyini Umehluko Kumaphakheji Wendabuko

Iyini i-COB encapsulated Cache on Board ) I-Bangbang isethwe ebhodini eliphrintiwe. Njengoba abahlinzeki be-IC behlisa i-QFP (indlela yokuhlanganisa izingxenye ze-SMT) ekulawuleni i-LCD kanye nokukhiqizwa kwama-chips ahlobene. Ngakho-ke, indlela ye-SMT yendabuko emikhiqizweni yesikhathi esizayo ishintshwa kancane kancane. Umehluko phakathi kobuchwepheshe bokupakisha be-COB nokupakishwa kwendabuko? Ukupakishwa kwe-COB yiphakheji elibopha i-chip ye-LED ngqo ebhodini le-PCB. Uyini umehluko phakathi kwale ndlela yokupakisha kanye ne-SMD LED yendabuko kanye namanye amasu okupakisha, futhi iyiphi engcono? Ukuqhathaniswa kwalezi zindlela ezimbili zokupakisha? Kunezinhlobo ezimbili eziyinhloko zobuchwepheshe be-chip nqunu: eyodwa ubuchwepheshe be-COB, kanti enye ubuchwepheshe be-FLIP Chip (FLIP Chip). Ubuchwepheshe bokupakisha be-LED COB Lokhu okubizwa nge-COB ukunamathela kwi-chip enqunu ene-conductive noma e-non-conductive adhesion ku-substrate exhumene, bese yenza ukhiye wokuhola ukuze kuzuzwe ukuxhumana kwayo kukagesi. Uma i-chip enqunu ivezwe ngokuqondile emoyeni, iyakwazi ukungcoliswa noma ukulimala okwenziwe, okuthinta noma ukucekela phansi umsebenzi we-chip, ngakho-ke i-chip kanye nokuhola okuyinhloko kuvalwe ngeglue. Abantu baphinde babize le ndlela yokupakisha ngokuthi isikhwama esithambile. I-chip enqunu embozwe ubuchwepheshe be-COB iwumzimba oyinhloko we-chip kanye namatheminali e-I/O ngaphezu kwekristalu. Ngesikhathi sokushisela, i-chip enqunu inamathela ku-PCB nge-conductive/thermal glue. Ngemva kokuqina ) Ngaphansi kwesenzo se-ultrasound nengcindezi yokushisa, xhuma endaweni yokushisela ye-chip ye-I/O kanye namaphedi ahambisanayo e-PCB, ngokulandelana. Ngemva kokuhlolwa, i-resin glue ivalwa. Uma kuqhathaniswa nobuchwepheshe bokupakisha bendabuko, ubuchwepheshe be-COB bunezinzuzo ezilandelayo: intengo ephansi; ukonga isikhala; ubuciko obuvuthiwe. Ubuchwepheshe bokupakisha be-LED COB nabo abanele, okungukuthi, umshini wokushisela ohlukile nomshini wokupakisha kuyadingeka. Kwesinye isikhathi isivinini asikwazi ukuhambisana nezidingo eziqinile ze-PCB zemvelo; ayinakugcinwa. I-COB, lobu buchwepheshe bokupakisha bendabuko buzodlala indima ebalulekile ekufakweni kwemikhiqizo ephathekayo. Izinkinga ezivamile zobuchwepheshe bokupakisha be-LED COB Q: Inqubo yokupakisha yomthombo wokukhanya we-LED ye-COB Inkinga yokunciphisa izinga lokushisa eliphakathi nombala. Lapho ukupakishwa kwe-COB kusetshenziswa ekufakweni kwe-COB, kusebenzisa inqubo yokupakisha yamandla aphezulu. Ngemuva kokubhaka, kutholakala ukuthi izinga lokushisa lombala lihlala likhulu kakhulu. , 5000K endaweni yokuqala, kodwa impushana yeglue ingu-10000K ngemva kokuba i-grill ishisiwe. Ingabe inkinga yenqubo yokubhaka ye-silicone noma i-glue powder ayifanelekile. Sicela wonke umuntu! A: Izinga lokushisa lokubhaka liphezulu kakhulu, futhi ibanga le-electrode liba seduze kakhulu. Nciphisa isikhathi sokufutha sibe yisikhathi sokubhaka. Umehluko wokushisa kombala kufanele udalwe yimpuphu ye-fluorescent. Ngokushesha ukuqina ukuze ugweme i-fluorescence powder! Buyekeza ijika lokushisisa lebhokisi le-Oven Q: Uyini umehluko phakathi kobuchwepheshe bokupakisha be-LAMP LED kanye nokupakishwa kwe-COB kubuchwepheshe bokupakisha be-LED? Zombili zifakwe ngqo esikhundleni sokupakishwa kwepheshi. Uyini umehluko? Yiziphi izici? Ingabe eyodwa ifanele amandla aphezulu, enye ifanele amandla amancane? A: Ubuchwepheshe be-COB ngokuvamile busebenza kakhulu ku-substrate efanayo nezinye izingxenye ze-elekthronikhi. Uma i-LED COB yenziwe iphakheji ye-encapsulation eqondile, kufanele ibe imojuli enemisebenzi ethile ekhethekile njengomsebenzi we-flash noma uhlamvu lwedijithali, imojula yokulawula umbala, njll. Kokubili amandla amakhulu namancane angaba yi-COB noma i-LAMP. Awukho umehluko kulesi sici. Q: Ngicela ukubuza ukupakishwa okuhlanganisiwe kwe-COB njengomthombo wokukhanya kwendiza, ingabe kuzongena esikhundleni semikhiqizo yamanje yesichibi? IMP: Akukho okushintshiwe, kokubili kusekuthuthukisweni okuzayo, futhi kokubili kuzohlala isikhathi eside.
