ʻO Tg ke ʻano o ke aniani hoʻololi wela. No ka mea, ʻo V-0 (UL 94-V0) ka flammability o ka papa kaapuni i pai ʻia, no laila, inā ʻoi aku ka mahana ma mua o ka waiwai Tg i koho ʻia, e hoʻololi ʻia ka papa mai ka moku aniani a hiki i ke kūlana rubbery a laila pili ka hana o ka PCB.
Inā ʻoi aku ka kiʻekiʻe o ka mahana hana o kāu huahana ma mua o ka maʻamau (130-140C), a laila pono e hoʻohana i ka High Tg PCB mea.> 170C. a kaulana PCB waiwai nui he 170C, 175C, a me 180C. ʻO ka maʻamau, ʻoi aku ka nui o ka waiwai o ka papa kaapuni FR4 Tg ma kahi o 10-20C ma mua o ka wela hana o ka huahana. Inā ʻoe 130TG papa, e emi ka mahana hana ma mua o 110C; inā e hoʻohana i ka papa TG kiʻekiʻe 170, a laila e emi ka mahana hana kiʻekiʻe ma mua o 150C.
ʻO ka mea hoʻolako papa kaapuni paʻi ʻenehana maikaʻi loa, i hoʻokumu ʻia ma Iune 28, 2006, he hui i kākau inoa ʻia ma Hong Kong.
