Waht ndi SMD LED BT gawo:

SMD LED BT Substrate amatanthauza THE PCB yomwe imapangidwa ndi BT Zida ndipo imagwiritsidwa ntchito pazinthu za SMD LED.Posiyana ndi PCB wamba , BT Zida zimagwiritsidwa ntchito mu MD LED BT Substrate, yomwe imagwiritsidwa ntchito kwambiri ndi Mistubishi Gas Chemical Co, Inc. Zipangizo za BT zopangidwa ndi B (Bismaleimide) ndi T (Triazine) utomoni uli ndi maubwino apamwamba a TG (255 ~ 330 ° C), kutentha kwamphamvu (160 ~ 230 ° C), kulimbikira kwa chinyezi, kusinthasintha kwa dielectric (DK) komanso kutaya pang'ono chinthu (Df). SMD LED ndi chida chatsopano chotulutsa kuwala kwa semiconductor, chobalalika pang'ono, chachikulu, chofanana, chodalirika kwambiri, mitundu yowala kuphatikiza mitundu yoyera, imagwiritsidwa ntchito kwambiri pazinthu zamagetsi zosiyanasiyana. PCB board ndi imodzi mwazinthu zazikulu zopanga SMD LED.

 Kusiyana b pakati pa SMD ndi COB LED

SMD imatanthawuza mawu akuti "Chipangizo Chokwera Pamwamba" ma LED, omwe ndi ma LED omwe amagawidwa kwambiri pamsika. Chip cha LED chimasakanizidwa kwamuyaya ndi board board (PCB), ndipo chimadziwika kwambiri chifukwa chogwiritsa ntchito zinthu zosiyanasiyana. iye PCB yamangidwa pachinthu chokhala ngati makona anayi, chopanda kanthu, chomwe ndi chomwe timakonda kuwona ngati SMD. Mukayang'ana mu SMD LED mwatcheru, mutha kuwona kakang'ono kakuda pakati pa SMD; ndicho chip cha LED. Mutha kuzipeza mu mababu owala ndi nyali zamagetsi komanso muzowunikira pafoni yanu.

Chimodzi mwazomwe zachitika posachedwa pamakampani a LED ndi ukadaulo wa COB kapena "Chip on Board" womwe ndi gawo lothandizira kugwiritsa ntchito mphamvu moyenera. Mofananamo ndi SMD, tchipisi cha COB timakhalanso ndi ma diode angapo pamtunda womwewo. Koma kusiyana pakati pa kuwala kwa COB ndi SMD ndikuti ma COB a LED ali ndi ma diode ambiri.

Ubwino wa SMD LED

1) SMD imasinthasintha, ndikuwonetsedwa kwa tchipisi chake kumasankhidwa malinga ndi kusanja kwa board board, ndipo imatha kusinthidwa kuti ikwaniritse njira zosiyanasiyana zaukadaulo.

2) Gwero lowala la SMD limakhala ndi chiwonetsero chokulirapo mpaka 120 & Phi; Madigiri a 160, kukula pang'ono ndi kulemera kopepuka kwa zinthu zamagetsi, kuchuluka kwa msonkhano waukulu ndi kukula ndi kulemera kwa zinthu zokutira zili pafupifupi 1/10 yokha yazinthu zodziwika bwino za plug-in.

3) Ili ndi kudalirika kwakukulu komanso kuthekera kwamphamvu kotsutsana ndi kugwedera.

4) Low solder olowa mlingo wopunduka ndi kusintha kupanga dzuwa.
