Amfanin High Tg PCB
Gabaɗaya, PCB FR4-Tg na yau da kullun shine digiri 130-140, matsakaici Tg ya fi digiri 150-160, kuma babban Tg ya fi digiri 170, Babban FR4-Tg zai sami mafi kyawun injina da juriya na sinadarai ga zafi da danshi fiye da daidaitaccen FR4, ga wasu fa'idodin babban Tg PCB don bita:
1. Mafi girman kwanciyar hankali: Zai inganta juriya na zafi ta atomatik, juriya na sinadarai, juriyar danshi, da kwanciyar hankali na na'urar idan ƙara Tg na PCB substrate.
2. Yi tsayayya da ƙirar ƙira mai ƙarfi: Idan na'urar tana da ƙarfin ƙarfin ƙarfi da ƙimar calorific mai ƙima, to babban Tg PCB zai zama kyakkyawan bayani don sarrafa zafi.
3. Ana iya amfani da allunan da'irar da'ira mafi girma don canza ƙira da buƙatun ƙarfin kayan aiki yayin rage haɓakar zafi na allunan talakawa, kuma ana iya amfani da babban Tg PCBS.
4. Zaɓin zaɓi na Multi-Layer da HDI PCB: Saboda Multi-Layer da HDI PCB sun fi ƙanƙanta da yawa da kewaye, zai haifar da babban matakin zubar da zafi. Sabili da haka, ana amfani da manyan TG PCBs a cikin Multi-Layer da HDI PCBs don tabbatar da amincin masana'antar PCB.
