Qaybaha Elektaroonigga ah ee Qaybaha Isku-dhafka ah ee Wareegga LM2904 ADS8341E/2K5 OPT3001IDNPRQ1 TPS79101DBVRG4Q1 ic chip

1.Waa maxay bonding (chip bonding and bonding)

isku xidhka waa hab of bonding in habka wax soo saarka chip, guud ahaan loo isticmaalo in lagu xidho circuitry gudaha chip in biinanka baakadda silig dahab ah ka hor baakadaha, iyo guud ahaan ka dib xidhitaanka (ie ka dib markii circuitry ku xiran biinanka) chip waa. oo lagu daboolay jel madow iyadoo la isticmaalayo tignoolajiyada sare ee baakadaha dibadda COB ( ChipOnBoard ), habkani waa in la tijaabiyay waferka epitaxial ee lagu dhex beeray guddiga wareegga gaarka ah, ka dibna wareegga wareegga epitaxial wuxuu ku xiran yahay guddiga wareegga oo leh silig dahab ah, ka dibna dhalaalay oo leh shaqo ilaalin gaar ah oo walxaha dabiiciga ah oo lagu daboolay wafers epitaxial si ay u dhammaystiraan xiritaanka ka dib ee chips-ka.

2.Waa maxay semiconductor?

Aan ku bilowno waxa uu yahay semiconductor.Marka laga eego dhinaca maaddada: semiconductor waa shay leh sifooyin wax-qabad oo u dhexeeya kuwa kaari iyo dahaye heerkulka qolka.Sida nolol maalmeedka, fiilooyinka naxaasta iyo aluminiumku waa kirishbooyada, halka caagga iyo wixii la mid ah ay yihiin kuwa dahsoon.Marka la eego korantada korantada: semiconductor waa shay leh korantada korantada, oo u dhexeysa insulator ilaa kirishbooyada.

Afarta guryaha ee semiconductors.

Helitaanka semiconductor-ka waxaa laga heli karaa ilaa 1833, markii Faraday, saynisyahankii Ingiriiska, iyo aabbihii elektiroonigga, uu ahaa qofkii ugu horreeyay ee ogaaday in caabbinta sulfide silver ay kala duwan tahay heerkul ka duwan kan biraha caadiga ah, kaas oo ahaa kii ugu horreeyay. daahfurka ifafaale semiconductor.

Laakin soo koobida guryaha semiconductors lama dhamaystirin ilaa December 1947 by Bell Laboratories.

Heerkulka ayaa kor u kaca, iska caabintuna hoos u dhacdo: caabbinta semiconductor ayaa hoos u dhacda marka heerkulku kordho, laakiin, guud ahaan, caabbinta birta waxay kordhisaa heerkulka.

Saamaynta sawir-qaadista: isgoysyada lagu sameeyay xidhiidhka u dhexeeya semiconductor iyo electrolyte waxay soo saartaa danab marka ay soo baxdo iftiinka.

Saamaynta sawir-qaadista: dhaqdhaqaaqa semiconductor wuxuu kordhiyaa joogitaanka iftiinka.

Saamaynta dib-u-habaynta: dhaqdhaqaaqa semiconductor waa jihada oo la xidhiidha jihada goobta korantada ee codsatay.Ku dar danab togan cidhifyada semiconductor waana korantada;haddii polarity danab dib loo rogo, ma aha mid waxtar leh.
