Kashi na biyu: Ƙa'idar Aiki Substrate Aluminum
Na'urorin wuta suna saman saman da'ira.Zafin da na'urorin ke samarwa yayin aiki ana yin su da sauri ta hanyar rufin da ke rufewa zuwa layin tushe na karfe, wanda daga nan ya watsar da zafi, yana samun zafi ga na'urorin.
Idan aka kwatanta da FR-4 na al'ada, kayan aikin aluminum na iya rage juriya na thermal, yana mai da su kyakkyawan jagoranci na zafi.Idan aka kwatanta da da'irorin yumbu na fim mai kauri, kuma suna da ingantattun kaddarorin inji.
Bugu da ƙari, aluminium substrates suna da fa'idodi na musamman masu zuwa:
- Yarda da buƙatun RoHs
- Kyakkyawan daidaitawa ga hanyoyin SMT
- Ingantacciyar kulawar watsawar thermal a cikin ƙirar kewaye don rage yawan zafin jiki na aiki, tsawaita rayuwa, haɓaka ƙarfin ƙarfi da aminci.
- Ragewa a cikin haɗar magudanar zafi da sauran kayan aiki, gami da kayan masarufi na thermal, wanda ke haifar da ƙaramin samfurin ƙarami da ƙarancin kayan masarufi da ƙimar taro, da mafi kyawun haɗin wutar lantarki da da'irori masu sarrafawa.
- Maye gurbin yumbura mai rauni don ingantacciyar ƙarfin injina
