Nyiaj hli yog SMD LED BT Substrate:

SMD LED BT Substrate yog hais txog qib PCB uas tsim nrog BT Cov Khoom Siv thiab siv rau SMD LED cov khoom lag luam.Qhov zoo los ntawm PCB ib txwm , Cov Khoom Siv BT tau thov rau hauv MD LED BT Substrate, uas yog cov khoom lag luam feem ntau ntawm Mistubishi Gas Chemical Co., Inc. Cov ntaub ntawv BT ua los ntawm B (Bismaleimide) thiab T (Triazine) cov khoom yas muaj qhov zoo ntawm TG siab (255 ~ 330 ° C), kub tsis kam (160 ~ 230 ° C), noo noo tsis kam, qis dielectric tas mus li (DK) thiab tsis tshua muaj dissipation yam (Df). SMD LED yog lub nplaim hluav taws xob tshiab sab nruab nrab lub tshuab hluav taws xob, cov khoom siv hluav taws xob me me sib txawv, nrog lub kaum sab xis me me yog qhov loj, lub teeb sib xws, kev ntseeg siab, lub teeb xim suav nrog cov xim dawb, nws tau siv dav hauv ntau yam khoom siv hluav taws xob. PCB lub rooj tsavxwm yog ib qho tseem ceeb ntawm kev tsim hluav taws xob SMD LED khoom.

Txawv b etween SMD thiab COB LED

SMD hais txog lub sij hawm "Nto Mounted Ntaus" LEDs, uas yog kev sib koom ua ke ntawm LED nyob rau hauv kev ua lag luam. Cov LED nti tau txuas mus ib txhis rau daim ntawv luam tawm Circuit Board (PCB), thiab nws yog qhov tshwj xeeb tshaj yog vim nws txoj kev ua ntau yam. nws PCB tau ua rau ntawm pob-voos-tiaj, tiaj tus yam, uas yog yam peb pom zoo li SMD. Yog tias koj saib mus rau hauv SMD LED ze, koj tuaj yeem pom ib qho dub me me txoj cai hauv nruab nrab ntawm SMD; uas yog LED nti. Koj tuaj yeem pom nws hauv cov ntaws hluav taws xob thiab cov teeb pom kev zoo thiab txawm tias hauv lub teeb ceeb toom ntawm koj lub xov tooj ntawm tes.

Ib qho ntawm cov kev tsim kho tshiab hauv kev lag luam LED yog COB lossis "Chip ntawm Board" technology uas yog cov kauj ruam tom ntej rau kev siv hluav taws xob ntau. Zoo ib yam li SMD, COB chips heev muaj ntau lub diodes ntawm tib qhov chaw. Tab sis qhov sib txawv ntawm LED teeb COB thiab SMD yog tias COB LED muaj ntau dua diodes.

Qhov zoo ntawm SMD LED

1) SMD yog hloov tau ntau dua, thiab cov zaub ntawm nws cov ntawv txiav txim siab txiav txim siab raws li cov ntawv luam tawm Circuit Circuit teeb, thiab nws tuaj yeem hloov kho kom tau raws li cov kev ua haujlwm sib txawv engineering.

2) SMD hom teeb ci loj tau ua rau lub teeb pom kev loj dua txog li 120 & Phi; 160 degrees, qhov loj me thiab qhov hnyav ntawm cov khoom siv hluav taws xob, qhov siab sib dhos thiab qhov loj thiab qhov hnyav ntawm cov npog cov khoom tsuas yog li 1/10 ntawm qhov ntawm cov pa ntawm cov khoom siv.

3) Nws muaj txoj kev ntseeg siab thiab muaj zog tiv thaiv kev co.

4) Tsawg solder qev yuam tus nqi thiab txhim kho kev ua hauj lwm zoo.
