Thyristor Mana Māmā (Ke ʻano Alloying)

wehewehe:

ʻO Thyristor, i ʻike ʻia ʻo Silicon Control Rectifier (SCR), he mana semiconductor mana kiʻekiʻe i loaʻa i ʻekolu mau hale PN.Ma ke ʻano o ka hana, ʻaʻole wale ka unidirectional conductivity ka thyristor, akā ʻoi aku ka maikaʻi o ka controllability ma mua o ka mea hoʻoponopono silicon, ʻelua wale nō mau mokuʻāina o ka conduction a me ka mokuʻāina, e kāohi i ka mana nui me ka mana liʻiliʻi, hoʻonui i ka mana a hiki i nā haneli a i ʻole. mau tausani manawa.He wikiwiki loa ka pane ʻana, e hoʻā a hoʻopau i nā kekona micro.ʻAʻole pili ka hana, ʻaʻohe ʻulaʻula, ʻaʻohe walaʻau, ʻoiai ke kiʻekiʻe o ka pono a me ke kumukūʻai haʻahaʻa.No laila, ʻoi loa i ka ʻōnaehana lako mana kiʻekiʻe, ua hoʻohana nui ʻia ka thyristor i ka rectifier circuit, static bypass switch, contact-free output switch and other circuits.

Ua hoʻokomo ʻia ka ʻenehana hana thyristor a me ka ʻenehana hana o RUNAU Electronics mai USA mai ka makahiki 1980, ma ke ʻano he paionia o ka hana ʻana i ka thyristor ma Kina, ua loaʻa i ka hui ʻenehana o RUNAU ka ʻike ʻoki a me ka ʻike hana nui no nā makahiki he 30.Ma ke kumu o ke kaʻina hana kuʻuna, ua hoʻomohala nā ʻenehana loea o RUNAU Electronics i ka ʻenehana loea i ka hana ʻana i ka thyristor me nā hiʻohiʻona maikaʻi o nā huahana ʻEulopa, ua hoʻomaikaʻi maikaʻi ʻia ka maikaʻi a me ka hana, ʻoi aku ka nui o nā lanakila i loaʻa i ka hoʻohana ʻana i ka uila uila. kahua, a ʻoi aku ka waiwai i hana ʻia no nā hoa.

Hoʻolauna:

1. Chip

ʻO ka puʻupuʻu thyristor i hana ʻia e RUNAU Electronics ua hoʻohana ʻia ka ʻenehana alloying sintered.ʻO ka silicon a me ka molybdenum wafer i hoʻopaʻa ʻia no ka hoʻohui ʻia ʻana e ka alumini maʻemaʻe (99.999%) ma lalo o ke kiʻekiʻe kiʻekiʻe a me ka wela wela.ʻO ka hoʻokele o nā ʻano sintering ka mea nui e hoʻopilikia i ka maikaʻi o thyristor.ʻO ka ʻike o ka RUNAU Electronics i hoʻohui ʻia i ka hoʻokele ʻana i ka hohonu o ka hui pū ʻana, ka palahalaha o ka ʻili, ka lua alloy a me ke akamai diffusion piha, ka ʻīpuka waena, ke ʻano pōʻai apo i hoʻohana ʻia e hiki ai i ka hana conduction pono a kiʻekiʻe o thyristor, i mea e hōʻoia i ka hana kiʻekiʻe.

2. Hoʻopili

Ma ke kaohi ʻana i ka palahalaha a me ka like o ka molybdenum wafer a me ka ʻeke waho, e hoʻopili ʻia ka chip a me ka wafer molybdenum me ka ʻeke waho paʻa a piha loa.ʻO ia ka mea e hoʻonui ai i ke kū'ē ʻana o ke au o ka piʻi ʻana a me ke kaapuni pōkole kiʻekiʻe.A ua hoʻohana ʻia ke ana o ka ʻenehana evaporation electron e hana i kahi kiʻi ʻoniʻoni alumini mānoanoa ma luna o ka ʻili wafer silika, a ʻo ka papa ruthenium i hoʻopaʻa ʻia ma ka ʻili molybdenum e hoʻonui nui i ka pale ʻana i ka wela, e hoʻonui nui ʻia ka manawa hana o thyristor.
