Fast Switch Thyristor (usoro YC ọkọlọtọ dị elu)

Nkọwa

Ọkọlọtọ n'ichepụta GE na teknụzụ nhazi bụ nke RUNAU Electronics webatara wee were ya n'ọrụ kemgbe 1980s.Ọnọdụ nrụpụta na nnwale zuru oke dabara na ihe achọrọ nke ahịa ahịa US.Dị ka a ọsụ ụzọ nke n'ichepụta thyristor na China, RUNAU Electronics enyela nka nke ala ike ngwá electronic na USA, European mba na zuru ụwa ọnụ ọrụ.Ọ tozuru oke yana nyocha site n'aka ndị ahịa yana nnukwu mmeri na uru ka emepụtara maka ndị mmekọ.

1. Chip

Chip thyristor nke RUNAU Eletrọnịkị rụpụtara bụ teknụzụ alloying gbanyere mkpọrọgwụ n'ọrụ.Emebere silicon na molybdenum wafer maka alloy site na aluminom dị ọcha (99.999%) n'okpuru oghere dị elu na gburugburu okpomọkụ dị elu.Nlekọta nke njirimara sintering bụ isi ihe na-emetụta ogo thyristor.The mara-how nke RUNAU Electronics na mgbakwunye na jikwaa alloy junction omimi, elu flatness, alloy oghere nakwa zuru mgbasa nkà, mgbanaka okirikiri ụkpụrụ, pụrụ iche ọnụ ụzọ Ọdịdị.Ọzọkwa a na-arụ ọrụ nhazi pụrụ iche iji belata ndụ onye na-ebu ngwaọrụ ahụ, nke mere na ngwa ngwa recombination nke dị n'ime ya na-eme ka ọ dịkwuo ngwa ngwa, a na-ebelata ụgwọ mgbake nke ngwaọrụ ahụ, na mgbanwe mgbanwe na-eme ka ọ dịkwuo mma.A na-etinye nha ndị dị otú ahụ iji kwalite njirimara mgbanwe ngwa ngwa, njirimara steeti, yana ihe onwunwe dị ugbu a.Arụ ọrụ na njikwa ọrụ nke thyristor bụ nke a pụrụ ịdabere na ya na nke ọma.

2. Encapsulation

Site n'iji nlezianya na-achịkwa ịdị larịị na myirịta nke molybdenum wafer na ngwugwu mpụga, mgbawa na molybdenum wafer ga-ejikọta ya na ngwugwu mpụga nke ọma na kpamkpam.Ndị dị otú ahụ ga-ebuli nguzogide nke ịwa ahụ ugbu a na elu mkpụmkpụ sekit ugbu a.A na-eji teknụzụ evaporation elektrọn rụọ ọrụ iji mepụta ihe nkiri alumini siri ike na elu silicon wafer, na ruthenium oyi akwa kpuchie na molybdenum n'elu ga-eme ka ike ọgwụgwụ ọkụ dịkwuo elu, oge ndụ ọrụ nke ngwa ngwa thyristor ga-abawanye nke ukwuu.
