Al'ada karfe-core buga kewaye allon (MCPCBs) da high thermal juriya saboda da ake bukata polymer rufi Layer tsakanin karfe da kewaye yadudduka, sa su ƙara m saduwa da zafi dissipation bukatun na high-iko da kuma matsananci-high-power LEDs. Sabanin haka,yumbu substrateshaɗa rufin rufi da haɓakar zafin jiki, kawar da juriyar yanayin zafi na tsaka-tsakin fuska da zama yanayin da ba za a iya kaucewa ba a cikin juyin halittar masana'antu.

1. Alumina (Al2O3)

Alumina  yumbura a halin yanzu shine mafi inganci kuma mafi yawan kayan da ake amfani da su. Yana nuna daidaitattun yanayin zafi na 25-30 W / m.K, ƙarfin injiniya mai kyau, da kyawawan halaye na dielectric.

Amfani:

• Balagagge fasaha

• Babban ƙarfin injiniya

• Kyakkyawan rufi

• Farashin farashi mai yawa

Aikace-aikace: An yi amfani da shi sosai a cikin hasken gabaɗaya, hasken baya na kayan lantarki na mabukaci, da na'urori masu ɗaukar matsakaicin ƙarfi.

2. Aluminum Nitride (AlN)

Don babban ƙarfin COB da hasken wutar lantarki mai daraja ta mota, AlN  ya yi fice saboda tsananin zafinsa.

Amfani:

• Ƙarfin wutar lantarki ya kai 170-230 W/m.K, kusan sau takwas na alumina

• Matsakaicin haɓakar haɓakar thermal yana dacewa sosai tare da kayan semiconductor kamar silicon da silicon carbide, yana haɓaka kwanciyar hankali na na'urori a cikin yanayin kekuna na thermal.

Aikace-aikace: Fitilolin mota, na'urori masu ƙarfi na masana'antu, da UVC zurfin ultraviolet kayan aikin tsarkakewa.

3. Silicon Nitride (Si3N4)

Silicon nitride yana magance ƙalubalen fasaha na ɓarna na asali na yumbu na al'ada, yana da tsananin ƙarfi da ƙarfi.

Amfani:

• Mai jurewa tasiri

• Mai jurewa jijjiga

• Kyakkyawan halayen thermal

Aikace-aikace: Fitilar matakin soja, kayan aikin optoelectronic sararin samaniya, da na'urorin LED masu daraja na masana'antu suna buƙatar babban dogaro.
