Kuthetha ntoni ukuPakisha kweCOB? Yeyiphi Umahluko kwiPackaging yesiNtu

Yintoni i-COB efakwe kwi-Cache kwiBhodi ) I-Bangbang ibekwe kwibhodi eprintiweyo. Njengoko ababoneleli be-IC banciphisa i-QFP (indlela yokufakwa kwe-encapsulation yeengxenye ze-SMT) ukupakishwa kulawulo lwe-LCD kunye nokuveliswa kweechips ezinxulumene nazo. Ke ngoko, indlela ye-SMT yemveli kwiimveliso ezizayo ithathelwa indawo ngokuthe ngcembe. Umahluko phakathi kwetekhnoloji yokupakisha yeCOB kunye nokupakishwa kwendabuko? Ukupakishwa kweCOB yiphakheji ebopha i-chip ye-LED ngqo kwibhodi ye-PCB. Nguwuphi umahluko phakathi kwale ndlela yokupakisha kunye ne-SMD yendabuko ye-LED kunye nezinye iindlela zokupakisha, kwaye yeyiphi engcono? Ukuthelekiswa kwezi ndlela zimbini zokupakisha? Kukho iindlela ezimbini eziphambili zeteknoloji ye-chip nude: enye iteknoloji yeCOB, kwaye enye iteknoloji ye-FLIP Chip (FLIP Chip). I-LED yokupakisha iteknoloji ye-COB ebizwa ngokuba yi-COB kukubambelela kwi-chip nude kunye ne-conductive okanye i-non-conductive adhesion kwi-substrate edibeneyo, kwaye emva koko yenza isitshixo esikhokelela ekufezekiseni uxhumano lwayo lombane. Ukuba i-chip ye-chip ibonakaliswe ngokuthe ngqo emoyeni, iyakwazi ukungcoliswa okanye umonakalo owenziweyo, uchaphazela okanye utshabalalise umsebenzi we-chip, ngoko i-chip kunye ne-key lead itywinwe ngeglue. Abantu bakwalubiza olu hlobo lokupakisha njengengxowa ethambileyo. Itshiphu enqunu efakwe kwitekhnoloji yeCOB ngumzimba ophambili wetshiphu kunye neetheminali ze-I/O ngaphezulu kwekristale. Ngexesha le-welding, i-chip ye-nude inamathele kwi-PCB kunye neglue eqhubayo / eshushu. Emva kokuqina ) Ngaphantsi kwesenzo se-ultrasound kunye noxinzelelo lwe-thermal, qhagamshela kwindawo ye-chip ye-I / O ye-terminal welding kunye neepads ezihambelanayo ze-PCB, ngokulandelanayo. Emva kokuba uvavanyo lugqithisiwe, i-resin glue itywinwe. Xa kuthelekiswa neteknoloji yokupakisha yendabuko, iteknoloji yeCOB ineenzuzo ezilandelayo: ixabiso eliphantsi; ukonga indawo; ubugcisa obuvuthiweyo. Itekhnoloji yokupakisha ye-LED COB nayo ayanelanga, oko kukuthi, umatshini wokuwelda owahlukileyo kunye nomatshini wokupakisha uyafuneka. Ngamanye amaxesha isantya asikwazi ukuhambisana neemfuno ezingqongqo ze-PCB zokusingqongileyo; ayinakugcinwa. I-COB, le teknoloji yokupakisha yendabuko iya kudlala indima ebalulekileyo ekupakishweni kweemveliso eziphathekayo. Iingxaki eziqhelekileyo zetekhnoloji yokupakisha ye-LED COB Q: Umthombo wokukhanya kwe-LED inkqubo yokupakisha i-COB yokupakisha Ingxaki yokunciphisa ubushushu bombala ophakathi. Xa ukupakishwa kweCOB kusetyenziswa kwipakethe yeCOB, isebenzisa inkqubo yokupakisha yamandla aphezulu. Emva kokubhaka, kufunyenwe ukuba ukushisa kombala kuhlala kukhulu kakhulu. , 5000K kwindawo yokuqala, kodwa i-glue powder yi-10000K emva kokuba i-grill ifakwe. Ngaba yingxaki yenkqubo yokubhaka ye-silicone okanye i-glue powder ayifanelekanga. Ncedani nonke! A: Iqondo lokushisa lokubhaka liphezulu kakhulu, kwaye umgama we-electrode usondele kakhulu. Lifutshane ixesha lokutshiza ukuya kwixesha lokubhaka. Umahluko wobushushu bombala kufuneka ubangelwe ngumgubo we-fluorescent. Ukuqina ngokukhawuleza ukuphepha umgubo we-fluorescence! Ukuphonononga ijika lokufudumeza kwebhokisi ye-Oven Q: Uthini umahluko phakathi kwe-LAMP ye-LED yokupakisha iteknoloji kunye nokupakishwa kwe-COB kwi-teknoloji yokupakisha ye-LED? Zombini zithe ngqo-zifakwe endaweni yokupakishwa kwepetshi. Yintoni umahluko? Yiyiphi imiba? Ngaba enye ifanelekile kumandla aphezulu, enye inamandla amancinci? A: Itekhnoloji ye-COB ngokuqhelekileyo isebenza ngakumbi kwi-substrate efanayo namanye amacandelo e-elektroniki. Ukuba i-COB ye-LED yenziwe kwiphakheji ye-encapsulation ngqo, kufuneka ibe yimodyuli enemisebenzi ekhethekileyo efana nomsebenzi we-flash okanye umlingiswa wedijithali, imodyuli yokulawula umbala, njl. Zombini amandla amakhulu kunye amancinci anokuba yiCOB okanye i-LAMP. Akukho mahluko kulo mba. Umbuzo: Ngaba ndingabuza ukupakishwa okuhlanganisiweyo kwe-COB njengomthombo wokukhanya kwenqwelomoya, ngaba iya kuthatha indawo yeemveliso zepatch zangoku? A: Akukho ukutshintshwa, zombini kuphuhliso lwexesha elizayo, kwaye zombini ziya kuhlala ixesha elide.
