Kuhlelo lokukhiqiza lwe-semiconductor oludinga kakhulu, lapho ukuchaneka kwe-nanoscale, ukuzinza kwesakhiwo, kanye nokusebenza kahle kokushisa kuchaza isivuno sokukhiqiza kanye nobude besikhathi semishini, ukukhethwa kwezinto zokwakha kuba yisinqumo esibalulekile sobunjiniyela. I-aluminium alloy engu-7075 iyi-alloy yokuqina kwesistimu ye-Al-Zn-Mg-Cu enamandla aphezulu. Ivele njengento ekhethwayo yezingxenye zemishini ye-semiconductor esebenza kahle kakhulu, idlula amazinga e-aluminium ajwayelekile futhi incintisana nensimbi ekusetshenzisweni kokuthwala umthwalo. Idume ngesilinganiso sayo samandla esiyingqayizivele kuya kwesisindo, ukuzinza okuphezulu kobukhulu, kanye nokusebenza kahle kakhulu kwemishini, i-7075 yenzelwe ukuhlangabezana namazinga aqinile okuphatha i-wafer, amakamelo okucubungula, imishini yokuhlola, kanye nezinto zokulungisa ngokunemba. Njengomkhiqizo oyinhloko ovela enkampanini yethu, ogxile kuAmapuleti e-aluminium angu-7075, imigoqo, amashubhu, kanye nomshini wokulungisa ngokunemba okwenziwe ngokwezifiso, lokhu kwaziswa kunikeza ukusebenza okungenakuqhathaniswa kwezinhlelo zokusebenza ezibaluleke kakhulu ze-semiconductor.

Izinto Eziyisisekelo Nokwakheka Kwamakhemikhali

I-7075 iyingxenye yochungechunge lwe-7000 lwama-alloy e-aluminium aqiniswe ngamandla aphezulu, abonakala ngokwakhiwa kwawo kwamakhemikhali okwenzelwe ukuqina kwemvula ephezulu. Ukwakheka kwe-alloy okuyisisekelo kulawulwa ngokunembile ukuqinisekisa izakhiwo ezihambisanayo zemishini: I-Zinc (Zn) 5.1% ~ 6.1% njenge-ejenti yokuqinisa eyinhloko.

I-Magnesium (Mg) 2.1%~2.9% ukwakha isigaba esinamandla se-MgZn₂ intermetallic.

Ithusi (Cu) 1.2%~2.0% ukuthuthukisa amandla okubamba kanye nokumelana nokugqwala kokucindezeleka,.

I-Chromium (Cr) 0.18% ~ 0.28% ukulawula isakhiwo sezinhlamvu nokuvimbela ukwenziwa kabusha kwekristalu.

Le recipe enembile ye-metallurgical, ehlanganiswe nezinqubo eziqinile zokuncibilikisa nokukhipha (kufaka phakathi ukukhipha igesi nge-vacuum kanye ne-homogenization), iphumela esakhiweni esincane esinobukhulu obuncane, esinobuthi obuphansi esibalulekile ezintweni zezinga le-semiconductor. Ngokungafani ne-alloy ejwayelekile ye-6061, i-7075 ayiklanyelwe ukwakheka okuphezulu kodwa yenzelwe ukusebenza kahle kakhulu kwemishini, okwenza ifaneleke kakhulu ezingxenyeni ezikhiqizwe nge-CNC machining kunokugoba noma ukwakha.

Izakhiwo Ezibalulekile Zemishini Nezomzimba Zezicelo Ze-Semiconductor

Isici esichazayo se-aluminium engu-7075 ukusebenza kwayo okungavamile komshini, ikakhulukazi esimweni sokushisa se-T651, isimo esichazwe kakhulu sezingxenye ze-semiconductor. Lesi simo sokushisa sibonisa ukwelashwa kokushisa kwesisombululo, kulandelwa ukucima okulawulwayo, ukunciphisa ukucindezeleka ngokwelula, kanye nokuguga okwenziwe, okususa ukucindezeleka kwangaphakathi okusele futhi kunikeze ukuzinza okumangalisayo kobukhulu.

- Amandla Aphezulu Kakhulu:I-7075-T651 inamandla okudonsa okungenani angu-560 MPa kanye namandla okukhiqiza angu-495 MPa, cishe kabili kunalawo angu-6061-T6 futhi afana nezinsimbi ezisebenzisa i-alloy ephansi. Lokhu kuvumela abaklami bemishini ye-semiconductor ukuthi bakhe izingxenye zesakhiwo ezincane nezilula ezingamelana nemithwalo esindayo engaguquki, amandla aguqukayo, kanye nokucindezela kwe-vacuum ngaphandle kokuphambuka noma ukuguquguquka.

- Ukumelana Nokukhathala Okuphakeme:I-alloy ikhombisa ukumelana okuhle kakhulu nokusabalala kokuqhekeka kokukhathala ngaphansi komthwalo ojikelezayo, isici esibalulekile sezinhlelo zokuphatha i-wafer ezenzakalelayo, izingalo zerobhothi, kanye nezigaba ezijikelezayo ezisebenza ngokuqhubekayo amahora ayizinkulungwane. Lokhu kuqinisekisa impilo yenkonzo ende futhi kunciphisa ukulungiswa okungahleliwe ezindaweni ezihlanzekile.

- Ukuzinza Okumangalisayo Kobukhulu:Uma ukunemba kulinganiswa ngama-micron, ukuphambuka okuncane kokushisa okungu-7075 kanye nokumelana okuphezulu kokugoba kubaluleke kakhulu. I-coefficient yayo yokwanda kokushisa iyahambisana futhi iyabikezelwa, iqinisekisa ukuthi ukubekezelelana okuqinile kugcinwa kuzo zonke izinguquko zokushisa ezitholakala emakamelweni okucubungula ama-semiconductor (kusukela ku-cryogenic kuya ku-thermal cycle ephezulu).

- Ubuningi obuphansi kanye nokuqina okuphezulu okuqondile:Njengoba ubukhulu bayo bungu-2.81 g/cm³, cishe ingxenye eyodwa kwezintathu kunensimbi, i-7075 ivumela ukunciphisa isisindo semishini okuphawulekayo. Lokhu kunciphisa amandla angasebenzi kahle ezinhlelweni zokubeka isivinini esikhulu, kuthuthukisa amazinga okusheshisa, futhi kunciphisa ukusetshenziswa kwamandla izici ezibalulekile zokuhlola i-wafer ethuthukisiwe kanye namathuluzi e-lithography.

- Ukushisa Okuthuthukisiwe:Ukulinganisela amandla nokuphathwa kokushisa, i-7075 inikeza ukuqhutshwa kokushisa okungaba ngu-150 ~ 160 W/m·K, iqeda ngempumelelo ukushisa okukhiqizwa ngesikhathi sezinqubo ze-semiconductor ezinamandla aphezulu ngenkathi igcina ukuqina kwesakhiwo.

Ubuchwepheshe Bokwenza Izinto Ezinhle Nokwenza Izinto Ngokwezifiso

Inzuzo enkulu ye-aluminium engu-7075, ikakhulukazi esimweni se-T6, ukuthi iyakwazi ukusebenza kahle kakhulu ekusebenzeni kwe-CNC ngokunemba. Inkampani yethu igxile ekuguquleniAmapuleti, imigoqo, namapayipi angu-7075zibe izingxenye ze-semiconductor ezenziwe ngokwezifiso, kusetshenziswa izici zokusika ezinhle zezinto ukuze kufezwe ukunemba okungenakuqhathaniswa:

- Ukuqeda Okuphezulu Komphezulu:Imishini engu-7075 ifinyelela ekuqedeni okubushelelezi kakhulu kobuso (Ra ≤ 0.4 μm) uma usebenzisa amathuluzi abukhali e-carbide noma e-PCD, isusa isidingo sokupholisha okwesibili futhi iqinisekise ukuvalwa kwe-vacuum okuhle kakhulu kanye nokumelana nokungcola kwezinhlayiya ezindaweni ezihlanzekile.

- Ukubekezelelana Okunembe Kakhulu:Sihlala sibamba ukubekezelelana okuqinile kuze kufike ku-±0.002 mm ngezici ezibalulekile, ngokunemba kwejometri okuhlanganisa ukufana ≤ 0.005 mm kanye nokuba flat ≤ 0.003 mm, sihlangabezana nezidingo eziqinile zama-chuck e-semiconductor wafer, izibambi ze-electrode, kanye nama-chamber liner.

- Amajiyometri Ayinkimbinkimbi:Ingxube isabela kahle ekusetshenzisweni kwemishini okusheshayo, okuvumela ukukhiqizwa kwezingxenye eziyinkimbinkimbi, ezinodonga oluncane, nezinemininingwane eminingi ezinezingqimba eziyinkimbinkimbi, imigodi ejulile, kanye nezici ezincane ezibalulekile emishinini yesimanje ye-semiconductor.

- Ukuhambisana Ngemva Kokucubungula:I-7075 yamukela kalula uhla lwezindlela zokwelapha ubuso ezibalulekile ekusetshenzisweni kwe-semiconductor, okuhlanganisa i-hard anodizing, i-electroless nickel plating, kanye ne-passivation. Lezi zindlela zokwelapha zithuthukisa ukumelana nokugqwala, ubulukhuni bendawo (kufika ku-500 HV), kanye nokungaqhubi kahle, okuvikela amagesi enqubo yokugqwala kanye nezindawo zokugqwala nge-plasma.

Izicelo Eziqondiwe Embonini Yezikhombisi-ndlela
