Tg yana nufin Yanayin Canjin Gilashin. Kamar yadda flammability na bugu Circuit Board (PCB) ne V-0 (UL 94-V0), don haka idan zafin jiki ya zarce darajar Tg, hukumar za ta canza daga gilashin jihar zuwa roba jihar sa'an nan kuma aikin PCB zai shafi.
Idan zafin aiki na samfurin ku ya fi na al'ada (130-140C), to dole ne kuyi amfani da kayan PCB na High Tg wanda shine> 170C. kuma mashahurin babban darajar PCB shine 170C, 175C, da 180C. Yawanci ƙimar allon kewayawa na FR4 Tg yakamata ya zama aƙalla 10-20C sama da zafin aiki na samfur. Idan ku 130TG jirgin, aiki zafin jiki zai zama ƙasa da 110C; idan amfani da 170 high TG board, to, matsakaicin zafin aiki ya kamata ya zama ƙasa da 150C.
