High Tg board

Lokacin da yawan zafin jiki na babban kwamiti na Tg ya tashi zuwa wani yanki, zahirin zai canza daga "yanayin gilashi" zuwa "jihar roba", kuma ana kiran yanayin zafin a wannan lokacin gilashin canjin gilashi (Tg) na farantin. A wasu kalmomin, Tg shine mafi girman zafin jiki (℃) wanda ƙarancin ya kasance mai tsauri. Wato, kayan PCB na zamani a yanayin zafin jiki ba wai kawai yana haifar da laushi, nakasawa, narkewa da sauran abubuwan mamaki ba, amma kuma yana nuna raguwar kayan masarufi da na lantarki (bana tsammanin kuna son ganin samfuransu sun bayyana a wannan yanayin ).

Janar Tg faranti sun wuce digiri 130, babban Tg gabaɗaya ya fi digiri 170, kuma matsakaiciyar Tg kusan fiye da digiri 150.

Yawancin lokaci, PCB tare da Tg≥170 ℃ ana kiransa babban kwamitin kewaye da Tg.

Tg na substrate yana ƙaruwa, kuma ƙarfin juriya, ƙwarin danshi, juriya na sinadarai, juriya ta kwanciyar hankali da sauran halaye na hukumar kewaye za'a inganta su kuma inganta. Mafi girman ƙimar TG shine, mafi kyawun aikin ƙarfin zafin jiki na farantin zai kasance. Musamman a cikin aikin ba tare da gubar ba, ana amfani da babban TG sau da yawa.
