Ibikoresho bya elegitoronike Utanga isoko Yuzuzanya Yuzuzanya LM2904 ADS8341E / 2K5 OPT3001IDNPRQ1 TPS79101DBVRG4Q1 ic chip

1.Guhuza ni iki (guhuza chip no guhuza)

guhuza nuburyo bwo guhuza mugikorwa cyo gukora chip, mubisanzwe bikoreshwa muguhuza uruziga rwimbere rwa chip kumapaki yamapaki hamwe ninsinga ya zahabu mbere yo gupakira, kandi mubisanzwe nyuma yo guhuza (nukuvuga nyuma yumuzunguruko uhujwe na pin) chip ni igizwe na gel yumukara mugihe ukoresheje tekinoroji yo hanze yo gupakira hanze ya COB (ChipOnBoard), iyi nzira ni ukugerageza wafer epitaxial wafer yatewe mukibaho cyihariye cyumuzunguruko, hanyuma epitaxial wafer umuzenguruko uhuza ikibaho cyumuzunguruko hamwe ninsinga za zahabu, hanyuma ugashonga hamwe numurimo udasanzwe wo kurinda ibikoresho kama bitwikiriwe na epitaxial wafers kugirango urangize nyuma ya encapsulation ya chip.

2.Igice cya kabiri ni iki?

Reka duhere kubyo semiconductor ari.Duhereye kubintu bifatika: igice cya kabiri ni ibikoresho bifite imiterere yimyitwarire hagati yuwuyobora na insuliranteri mubushyuhe bwicyumba.Nko mubuzima bwa buri munsi, insinga z'umuringa na aluminium ni kiyobora, mugihe reberi nibindi bisa na insulator.Kubijyanye no gukwirakwiza amashanyarazi: igice cya kabiri ni ibikoresho bifite amashanyarazi agenzurwa, kuva kuri insulator kugeza kiyobora.

Ibintu bine bya semiconductor.

Ivumburwa rya semiconductor rishobora guhera mu 1833, igihe Faraday, umuhanga w’Ubwongereza, akaba na se wa elegitoroniki, ni we wa mbere wavumbuye ko kurwanya sulfide ya silver bitandukanye n’ubushyuhe butandukanye n’ubwa metero zisanzwe, bwari ubwa mbere kuvumbura icyerekezo cya semiconductor.

Ariko incamake yumutungo wa semiconductor ntabwo yujujwe kugeza Ukuboza 1947 na Laboratoire ya Bell.

Ubushyuhe burazamuka, kandi ubukana buragabanuka: guhangana na semiconductor bigabanuka uko ubushyuhe buzamuka, ariko, muri rusange, kurwanya icyuma byiyongera hamwe nubushyuhe.

Ingaruka ya Photovoltaque: ihuriro ryakozwe no guhuza hagati ya semiconductor na electrolyte itanga voltage iyo ihuye numucyo.

Ingaruka ya Photoconductive: imiyoboro ya semiconductor yiyongera imbere yumucyo.

Ingaruka yo gukosora: ubwikorezi bwa semiconductor ni icyerekezo kandi kijyanye nicyerekezo cyumuriro wamashanyarazi washyizweho.Ongeraho voltage nziza kumpera ya semiconductor kandi irayobora;niba voltage polarite ihinduwe, ntabwo byoroshye.
