Mu gawo la kupanga ma semiconductor, zida zowunikira zodziwikiratu (AOI) zimagwira ntchito yofunika kwambiri pakuwonetsetsa kuti ma chips ndi abwino. Ngakhale kusintha pang'ono pakulondola kwa kuzindikira kumatha kubweretsa kusintha kwakukulu kumakampani onse. Zida, monga gawo lofunikira, zimakhudza kwambiri kulondola kwa kuzindikira. M'zaka zaposachedwa, kusintha kwa zinthu zoyambira kwafalikira m'makampani onse. Granite, yokhala ndi magwiridwe antchito abwino kwambiri oletsa kugwedezeka, pang'onopang'ono yasintha zinthu zachikhalidwe zachitsulo chopangidwa ndi chitsulo ndipo yakhala chida chatsopano chomwe chimakonda kwambiri pazida zowunikira za AOI. Kugwira ntchito kwake koletsa kugwedezeka kwawonjezeka ndi 92% poyerekeza ndi chitsulo chopangidwa ndi chitsulo. Ndi kupita patsogolo kotani kwaukadaulo ndi kusintha kwa mafakitale komwe kuli kumbuyo kwa deta iyi?
Zofunikira zokhwima pakugwedezeka kwa zida zowunikira za AOI za semiconductor
Njira yopangira ma chips a semiconductor yalowa munthawi ya nanoscale. Pa nthawi yowunikira AOI, ngakhale kugwedezeka kochepa kwambiri kungayambitse kusintha kwa zotsatira za kuwunika. Mikwingwirima yaying'ono, ma voids ndi zolakwika zina pamwamba pa chip nthawi zambiri zimakhala pa mulingo wa micrometer kapena nanometer. Magalasi owoneka bwino a zida zowunikira amafunika kujambula tsatanetsatane uwu molondola kwambiri. Kugwedezeka kulikonse komwe kumaperekedwa ndi maziko kumayambitsa lens kusuntha kapena kugwedezeka, zomwe zimapangitsa kuti chithunzicho chisawonekere ndipo motero zimakhudza kulondola kwa kuzindikira zolakwika.
Zipangizo zachitsulo chopangidwa ndi chitsulo chopangidwa ndi chitsulo zinkagwiritsidwa ntchito kwambiri m'mabowo a zida zowunikira za AOI chifukwa zimakhala ndi mphamvu zinazake komanso magwiridwe antchito, ndipo mtengo wake ndi wotsika. Komabe, pankhani yoletsa kugwedezeka, chitsulo chopangidwa ndi chitsulo chopangidwa ndi chitsulo chili ndi zofooka zoonekeratu. Kapangidwe ka mkati mwa chitsulo chopangidwa ndi chitsulo chopangidwa ndi chitsulo chili ndi mapepala ambiri a graphite, omwe ndi ofanana ndi malo ang'onoang'ono mkati mwake ndipo amasokoneza kupitiriza kwa zinthuzo. Zipangizo zikagwira ntchito ndikupanga kugwedezeka, kapena kusokonezedwa ndi kugwedezeka kwa chilengedwe chakunja, mphamvu ya kugwedezeka singathe kuchepetsedwa bwino mu chitsulo chopangidwa ndi chitsulo chopangidwa ndi chitsulo koma nthawi zonse imawonetsedwa ndikuyikidwa pakati pa pepala la graphite ndi matrix, zomwe zimapangitsa kuti kugwedezeka kupitirire. Mayeso oyenerera akuwonetsa kuti maziko a chitsulo chopangidwa ndi ...
Chinsinsi cha kuwonjezeka kwa 92% kwa mphamvu yoletsa kugwedezeka kwa maziko a granite
Granite, monga mwala wachilengedwe, yapanga kapangidwe ka mkati kolimba kwambiri komanso kofanana kudzera munjira za geological kwa zaka mazana ambiri. Imapangidwa makamaka ndi makhiristo amchere monga quartz ndi feldspar ogwirizana kwambiri, ndipo maukonde a mankhwala pakati pa makhiristo ndi olimba komanso okhazikika. Kapangidwe kameneka kamapatsa granite mphamvu yabwino kwambiri yoletsa kugwedezeka. Pamene kugwedezeka kumatumizidwa ku maziko a granite, makhiristo amchere omwe ali mkati mwake amatha kusintha mphamvu yogwedezeka kukhala mphamvu yotentha ndikuyichotsa. Kafukufuku akuwonetsa kuti kunyowa kwa granite kumakhala kokwera kangapo kuposa kwa chitsulo chosungunula, zomwe zikutanthauza kuti imatha kuyamwa mphamvu yogwedezeka bwino, kuchepetsa kutalika ndi nthawi ya kugwedezeka. Pambuyo poyesa akatswiri, pansi pa mikhalidwe yofanana ya kugwedezeka, nthawi yochepetsera kugwedezeka kwa maziko a granite ndi 8% yokha ya chitsulo chosungunula, ndipo mphamvu yochepetsera kugwedezeka yawonjezeka ndi 92%.
Kulimba kwambiri ndi modulus yolimba kwambiri ya granite zimathandizanso kwambiri. Kulimba kwambiri kumatsimikizira kuti maziko satha kusokonekera akanyamula kulemera kwa zida ndi mphamvu zakunja, ndipo nthawi zonse amakhala ndi chithandizo chokhazikika. Modulus yolimba kwambiri imatsimikizira kuti maziko amatha kubwerera mwachangu ku mawonekedwe ake oyambirira akagwedezeka, zomwe zimachepetsa kuchuluka kwa kugwedezeka. Kuphatikiza apo, granite ili ndi kukhazikika kwabwino kwa kutentha ndipo sichikhudzidwa ndi kusintha kwa kutentha kwa chilengedwe, kupewa kukulitsa kutentha ndi kusintha kwa kupindika komwe kumachitika chifukwa cha kusinthasintha kwa kutentha, motero kuonetsetsa kuti magwiridwe antchito oletsa kugwedezeka ndi olimba.
Kusintha kwa Makampani ndi Ziyembekezo Zoyambitsidwa ndi maziko a granite
Zipangizo zowunikira za AOI zokhala ndi maziko a granite zasintha kwambiri kulondola kwake kozindikira. Zingathe kuzindikira zolakwika mu ma chips ang'onoang'ono, kuchepetsa chiwopsezo cholakwika kufika pa 1% ndikuwonjezera kwambiri kuchuluka kwa zokolola za ma chips. Pakadali pano, kukhazikika kwa zida kwawonjezeka, kuchepetsa kuchuluka kwa kutseka kokonza komwe kumachitika chifukwa cha mavuto ogwedezeka, kukulitsa nthawi yogwira ntchito ya zida, ndikuchepetsa ndalama zonse zogwirira ntchito.
