Loaʻa nā mea PCB FR4 ma waena o TG (medium glass transition temperature) a me TG kiʻekiʻe (high glass transition temperature).
ʻO TG e pili ana i ka mahana hoʻololi aniani, ʻo ia hoʻi, ma kēia mahana, e hoʻololi ʻia ka pepa FR4, e hopena i nā loli i nā waiwai kino o ka mea.ʻO ka mahana hoʻololi aniani o nā lau TG maʻamau ma kahi o 130-140 degere Celsius, aʻo ka mahana hoʻololi aniani o nā lau TG kiʻekiʻe ma luna o 150 degere Celsius.ʻOi aku ka maikaʻi o ke kūpaʻa wela a me ke kūpaʻa wela kiʻekiʻe, a kūpono i nā noi e pono ai ke kū i nā wahi wela kiʻekiʻe, e like me ka uila uila, ka mana ʻoihana, aerospace a me nā kahua ʻē aʻe.ʻOi aku ka maikaʻi o nā pepa TG Medium no nā huahana uila maʻamau a me nā lako kamaʻilio a me nā kula ʻē aʻe.
ʻO ke koho ʻana i ke ʻano panel kūpono e pili ana i nā koi a me nā kūlana kaiapuni i ka noi kikoʻī.
