I-Waht yi-SMD ye-LED ye-BT Substrate:

I-SMD ye-LED ye-BT Substrate ibhekisa kwi-PCB eyenziwe ngezixhobo ze-BT kwaye isetyenzisiwe kwiimveliso ze-SMD ze-LED.Ukuhluka kwi- PCB eqhelekileyo , izinto ze-BT zisetyenziswa kwi-MD LED BT Substrate, eyimveliso ikakhulu yiMistubishi Gas Chemical Co, Inc. Izinto ze-BT ezenziwe nge-B (Bismaleimide) kunye ne-T (Triazine) zinezibonelelo ze-TG ephezulu (255 ~ 330 ° C), ukumelana nobushushu (160 ~ 230 ° C), ukuxhathisa ukufuma, i-dielectric rhoqo (DK) kunye nokusasazeka okuphantsi into (Df). I-SMD ye-LED yindawo entsha ekhupha ukukhanya kwesixhobo sokukhupha ukukhanya, enekona encinci yokusasaza inkulu, ukufana ukukhanya, ukuthembeka okuphezulu, imibala ekhanyayo kubandakanya imibala emhlophe, isetyenziswa ngokubanzi kwiimveliso ezahlukeneyo zombane. Ibhodi ye-PCB yenye yezinto eziphambili ze-SMD ze-LED.

Umahluko b phakathi kwe-SMD kunye ne-COB ye-LED

I-SMD ibhekisa kwigama elithi "Izixhobo eziPhezulu eziPhezulu" ze-LED, ezizezona zibalaseleyo ze-LED kwintengiso. I-chip ye-LED ixutywe ngonaphakade kwibhodi yesekethe eprintiweyo (i-PCB), kwaye ithandwa ngokukodwa ngenxa yokuguquguquka kwayo. i-PCB yakhelwe kwinto emile eluxande, iflethi, yile nto sihlala siyibona njenge-SMD. Ukuba ujonga kwi-SMD ye-LED ngokusondeleyo, ungabona indawo encinci emnyama embindini weSMD; Leyo yi-chip ye-LED. Ungayifumana kwiibhalbhu ezikhanyayo kunye nezibane zefilament kunye nakwisibane sokukhanya kwifowuni yakho ephathekayo.

Olunye uphuhliso lwamva nje kumzi mveliso we-LED yi-COB okanye itekhnoloji ye- "Chip on Board" eyinyathelo eliya phambili ekusebenziseni amandla ngakumbi. Ifana ne-SMD, ii-chip ze-COB nazo zinee-diode ezininzi kwindawo efanayo. Kodwa umahluko phakathi kokukhanya kwe-COB kunye ne-SMD kukuba ii-COB ze-LED zinee-diode ezingaphezulu.

Izinto eziluncedo ze-SMD LED

1) I-SMD ibhetyebhetye ngakumbi, kwaye ukuboniswa kweetshipsi zayo kugqitywe ngokobume bebhodi yesekethe eprintiweyo, kwaye inokutshintshwa ukuhlangabezana nezisombululo ezahlukeneyo zobunjineli.

2) Umthombo wokukhanya kwe-SMD unekona enkulu yokukhanyisa efikelela kwi-120 & Phi; Iidigri eziyi-160, ubungakanani obuncinci kunye nobunzima bokukhanya kweemveliso ze-elektroniki, ukuxinana kwindibano ephezulu kunye nobukhulu kunye nobunzima bezinto zokugubungela zi-1/10 kuphela zezinto eziqhelekileyo zeplagi.

I-3) inokuthenjwa okuphezulu kunye namandla okulwa nokungcangcazela.

I-4) Iqondo eliphantsi lokuthengisa ngokudibeneyo kunye nokuphucula ukusebenza kwemveliso.
