Waht shine SMD LED BT Substrate:

SMD LED BT Substrate yana nufin PCB wanda aka ƙera shi da kayan BT kuma ana amfani dashi akan samfuran SMD LED.Daban banbanci daga PCB na al'ada , ana amfani da kayan BT a cikin MD LED BT Substrate, wanda galibi samfurin Mistubishi Gas Chemical Co., Inc. Abubuwan BT da aka yi da B (Bismaleimide) da resin T (Triazine) suna da fa'idodi na babban TG (255 ~ 330 ° C), juriya mai zafi (160 ~ 230 ° C), ƙarfin juriya, ƙarancin wutar lantarki mai ƙarfi (DK) da ƙananan yaduwa factor (Df). SMD LED wani sabon abu ne wanda ke haskaka wutar lantarki, tare da karamin watsawa yana da girma, daidaitaccen haske, dogaro mai girma, launuka masu haske gami da fararen launuka, ana amfani dashi sosai a cikin kayayyakin lantarki da dama. Kwamitin PCB shine ɗayan manyan masana'antar SMD LED abu.

Bambanci b tsakanin SMD da COB LED

SMD tana nufin kalmar "faceariyar Dutsen Na'ura" LEDs, waɗanda sune matattarar LED da aka raba a kasuwa. Fushin LED yana hade har abada zuwa allon zagaye (PCB), kuma sanannen sanannen abu ne saboda iyawarsa. an gina PCB ne a kan abu mai fasalin rectangular, mai lebur, wanda muke yawanci gani kamar SMD. Idan kun duba cikin SMD LED a hankali, zaku iya ganin ƙaramin ma'anar baƙar fata dama a tsakiyar SMD; wancan shine chip din LED. Kuna iya samun sa a cikin kwararan wuta da fitilun filament har ma da hasken sanarwa akan wayarku ta hannu.

Ofaya daga cikin abubuwan da suka faru a cikin masana'antar LED shine fasaha ta COB ko "Chip on Board" wanda shine ci gaba don ingantaccen amfani da makamashi. Mai kama da SMD, kwakwalwan COB suma suna da diodes da yawa akan farfajiyar. Amma bambanci tsakanin LED light COB da SMD shine cewa COB LEDs suna da ƙarin diodes.

Fa'idodi na SMD LED

1) SMD ya fi sassauƙa, kuma ana nuna nunin kwakwalwan sa gwargwadon yadda aka tsara layin kwamitin kewaye, kuma ana iya canza shi don haɗuwa da hanyoyin injiniyan daban-daban.

2) Tushen hasken SMD yana da kusurwar haskakawa mai girma har zuwa 120 & Phi; Darajoji 160, karami da nauyin haske na kayayyakin lantarki, yawan haduwar taro da girma da nauyin kayan aikin murfin sune kusan 1/10 na na kayan hada-hada na al'ada.

3) Yana da babban abin dogaro da ƙarfin anti-vibration iyawa.

4) Low solder hadin gwiwa aibi kudi da kuma inganta samar yadda ya dace.
