I-Waht yi-SMD LED BT Substrate:

I-SMD LED BT Substrate ibhekisa ku-PCB eyenziwe ngezinto ze-BT futhi isetshenziselwe imikhiqizo ye-SMD ye-LED.Okuhlukile ku- PCB ejwayelekile , i-BT Materials isetshenziswa ku-MD LED BT Substrate, ikakhulukazi eyumkhiqizo weMistubishi Gas Chemical Co., Inc. Izinto ze-BT ezenziwe nge-resin ye-B (Bismaleimide) ne-T (Triazine) inezinzuzo ze-TG ephezulu (255 ~ 330 ° C), ukumelana nokushisa (160 ~ 230 ° C), ukumelana nomswakama, i-dielectric engapheli (DK) nokushabalalisa okuphansi isici (Df). I-SMD LED iyinsimbi entsha ekhipha ukukhanya kwe-semiconductor, ene-engela encane yokusabalalisa inkulu, ifana ngokukhanya, inokwethenjelwa okuphezulu, imibala ekhanyayo efaka imibala emhlophe, isetshenziswa kakhulu emikhiqizweni ehlukahlukene kagesi. PCB ibhodi ingenye yezinto ezinkulu yokukhiqiza SMD LED impahla.

Umehluko b phakathi kwe-SMD ne-COB LED

I-SMD ibhekisela ethempelini elithi “Surface Mounted Device” LEDs, okungama-LED abiwa kakhulu emakethe. I-chip ye-LED ihlanganiswe ingunaphakade kubhodi yesifunda ephrintiwe (i-PCB), futhi ithandwa kakhulu ngenxa yokusebenza kwayo okuhlukahlukene. i-PCB yakhelwe entweni emise okonxande, eyisicaba, nokuyinto esivame ukuyibona njenge-SMD. Uma ubhekisisa i-SMD LED eduze, ungabona iphuzu elincane elimnyama maphakathi ngqo ne-SMD; leyo yi-chip ye-LED. Ungayithola kuma-light bulbs nakuma-filament lights ngisho nasokhanyeni lesaziso kufoni yakho ephathekayo.

Enye intuthuko yakamuva embonini ye-LED ubuchwepheshe be-COB noma i- “Chip on Board” okuyisinyathelo esidlulela phambili ekusebenziseni amandla ngendlela ephumelelayo. Ngokufana ne-SMD, ama-chips we-COB nawo anama-diode amaningi endaweni efanayo. Kepha umehluko phakathi kwe-LED light COB ne-SMD ukuthi ama-COB LED anama-diode amaningi.

Izinzuzo ze-SMD LED

1) I-SMD iguquguquka kalula, futhi ukuboniswa kwamachips ayo kunqunywa ngokuya ngesakhiwo sebhodi lesifunda esiphrintiwe, futhi kungashintshwa ukuhlangabezana nezixazululo ezahlukahlukene zobunjiniyela.

2) Umthombo wokukhanya we-SMD une-engeli enkulu yokukhanyisa efinyelela ku-120 & Phi; Ama-degree angama-160, usayizi omncane kanye nesisindo esincane semikhiqizo ye-elekthronikhi, ukuminyana okuphezulu kobukhulu nosayizi nesisindo sezinto zekhava cishe kungu-1/10 walokho kwezakhi ezivamile zokuxhuma.

I-3) Inokwethenjelwa okuphezulu namandla wokulwa nokudlidliza.

4) solder okuphansi ngokuhlanganyela ukukhubazeka isilinganiso futhi ngcono ukukhiqizwa kahle.
