Pono ʻo PCB e pale i ke ahi a ʻaʻole hiki ke wela i kekahi mahana, e palupalu wale. ʻO ka helu wela i kēia manawa ua kapa ʻia ʻo ke aniani transition temperature (TG point), e pili ana i ka nui o ka paʻa o ka PCB.

He aha nā TG PCB kiʻekiʻe a me nā pono o ka hoʻohana ʻana i ka TG PCB kiʻekiʻe?

Ke piʻi ka mahana o ka PCB TG kiʻekiʻe i kekahi mau mea, e hoʻololi ka substrate mai ka "mokuʻāina aniani" a i "ka moku'āina rubber", a laila kapa ʻia ka mahana i kēia manawa ʻo ka vitrification temperature (TG) o ka papa. I nā huaʻōlelo ʻē aʻe, ʻo TG ka wela kiʻekiʻe loa e paʻa ai ka substrate.

He aha ke ʻano o ka papa PCB?

Hōʻike ka pae mai lalo a luna e like me lalo:

94HB － 94VO － 22F － CEM-1 － CEM-3 － FR-4

Penei nā kikoʻī:

94HB: pahu pahu maʻamau, ʻaʻole pale ahi (mea haʻahaʻa haʻahaʻa, make punching, ʻaʻole hiki ke hana ʻia i papa mana)

94V0: pahu pahu pale ahi (kuʻi make)

22F: papa aniani aniani ʻaoʻao hoʻokahi (ke kuʻi make)

CEM-1: papa fiberglass ʻaoʻao hoʻokahi (pono e hana ʻia ka wili ʻana i ka lolouila, ʻaʻole e make ke kuʻi)

CEM-3: papa fiberglass ʻaoʻao ʻelua (ka mea haʻahaʻa loa o ka papa ʻaoʻao ʻelua koe wale nō ka papa ʻaoʻao ʻelua, hiki ke hoʻohana ʻia kēia mea no nā panela pālua, ʻoi aku ka maikaʻi ma mua o FR4)

FR4: papa fiberglass ʻaoʻao ʻelua
