I loko o ka ʻōnaehana hana semiconductor ultra-koi, kahi e wehewehe ai ka pololei nanoscale, ke kūpaʻa kūkulu, a me ka pono thermal i ka hua hana a me ka lōʻihi o nā lako, lilo ke koho ʻana o nā mea kūkulu i mea hoʻoholo koʻikoʻi ʻenekinia. ʻO ka 7075 alumini alloy he Al-Zn-Mg-Cu system precipitation hardening alloy ikaika kiʻekiʻe. ua puka mai ʻo ia ma ke ʻano he mea koho no nā ʻāpana lako semiconductor hana kiʻekiʻe, e ʻoi aku ana ma mua o nā papa alumini maʻamau a hoʻokūkū pū me ke kila i nā noi lawe ukana. Kaulana no kona lakio ikaika-a-kaumaha kūikawā, ke kūpaʻa dimensional kiʻekiʻe, a me ka mīkini maikaʻi loa, ua hana ʻia ʻo 7075 e hoʻokō i nā kūlana koʻikoʻi o ka lawelawe wafer, nā keʻena hana, nā mīkini nānā, a me nā mea paʻa pololei. Ma ke ʻano he huahana koʻikoʻi mai kā mākou hui, loea i7075 mau papa alumini, nā kaola, nā paipu, a me ka mīkini kikoʻī maʻamau, hāʻawi kēia mea i ka hana kūpono ʻole no nā noi semiconductor koʻikoʻi loa.

Nā Kumu Mea a me ka Hoʻohui Kemika

No ka moʻo 7000 o nā mea hoʻohuihui alumini ikaika kiʻekiʻe ka 7075, i hōʻailona ʻia e kona ʻano kemika i hoʻomaikaʻi ʻia no ka paʻakikī ʻana o ka ua nui loa. Hoʻomalu pololei ʻia ka ʻano kumu o ka mea hoʻohuihui e hōʻoia i nā waiwai mechanical kūlike: Zinc (Zn) 5.1% ~ 6.1% ma ke ʻano he mea hoʻoikaika mua.

Magnesium (Mg) 2.1%~2.9% e hana i ka pae intermetallic MgZn₂ ikaika.

Keleawe (Cu) 1.2%~2.0% e hoʻoikaika i ka ikaika tensile a me ke kūpaʻa i ka corrosion stress.

Chromium (Cr) 0.18%~0.28% e kāohi i ke ʻano o ka palaoa a kāohi i ka recrystallization.

ʻO kēia ʻano hana metallurgical pololei, i hui pū ʻia me nā kaʻina hana hoʻoheheʻe a me ka hoʻolei ʻana (me ka vacuum degassing a me ka homogenization), e hopena i kahi microstructure grained maikaʻi, haʻahaʻa-porosity e pono ai no nā mea semiconductor grade. ʻAʻole e like me ka alloy 6061 maʻamau, ʻaʻole i hoʻolālā ʻia ʻo 7075 no ke ʻano kiʻekiʻe akā ua hana ʻia no ka hana mechanical kiʻekiʻe, e kūpono ana no nā ʻāpana i hana ʻia ma o ka CNC machining ma mua o ke kulou ʻana a i ʻole ke kūkulu ʻana.

Nā Waiwai Mekanika a me ke Kino Koʻikoʻi no nā Noi Semiconductor

ʻO ke ʻano hoʻākāka o ka alumini 7075 ʻo ia kāna hana mechanical kupaianaha, ʻoi aku hoʻi i ka mahana T651, ke kūlana kikoʻī loa no nā ʻāpana semiconductor. Hōʻike kēia mahana i kahi mālama wela hopena, ukali ʻia e ka quenching i kāohi ʻia, ka hoʻomaha ʻana i ke kaumaha ma o ka hoʻolōʻihi ʻana, a me ka ʻelemakule artificial, kahi e hoʻopau ai i nā kaumaha kūloko i koe a hāʻawi i ke kūpaʻa dimensional kūikawā.

- Ikaika Loa Loa:Hoʻohanohano ka 7075-T651 i ka ikaika tensile hope loa o 560 MPa a me ka ikaika yield o 495 MPa, kokoke i ka pālua o ka 6061-T6 a hoʻohālikelike ʻia me nā kila haʻahaʻa-alloy. ʻAe kēia i nā mea hoʻolālā lako semiconductor e hana i nā ʻāpana kūkulu lahilahi a māmā e hiki ke kū i nā ukana static kaumaha, nā ikaika dynamic, a me nā kaomi vacuum me ka ʻole o ka deflection a i ʻole deformation.

- Ke kūpaʻa luhi kiʻekiʻe:Hōʻike ka hui hao i ke kūpaʻa maikaʻi loa i ka laha ʻana o ka māwae luhi ma lalo o ka hoʻouka cyclic, kahi ʻano koʻikoʻi no nā ʻōnaehana lawelawe wafer automated, nā lima robotic, a me nā pae wili e hana mau ana no nā tausani hola. Hōʻoia kēia i ke ola lawelawe lōʻihi a hoʻemi i ka mālama pono ʻole ʻia ma nā wahi lumi maʻemaʻe.

- Paʻa Ana Kūikawā:Ke ana ʻia ka pololei ma nā microns, he mea waiwai nui ka hoʻololi wela liʻiliʻi o 7075 a me ke kū'ē kiʻekiʻe i ka warping. He kūlike a wānana ʻia kona coefficient o ka hoʻonui wela, e hōʻoia ana e mālama ʻia nā hoʻomanawanui paʻa ma waena o nā loli wela ākea i loko o nā keʻena hana semiconductor (mai ka cryogenic a i ka hoʻonui ʻia ʻana o ka thermal cycling).

- Haʻahaʻa ka Density a me ke Kiʻekiʻe o ka ʻOʻoleʻa:Me ka nui o 2.81 g/cm³, ma kahi o hoʻokahi hapakolu o ke kila, hiki i ka 7075 ke hōʻemi nui i ke kaumaha o nā lako. Hoʻemi kēia i nā ikaika inertial i nā ʻōnaehana hoʻonohonoho wikiwiki, hoʻomaikaʻi i nā wikiwiki wikiwiki, a hoʻohaʻahaʻa i ka hoʻohana ʻana i ka ikehu i nā mea koʻikoʻi no ka nānā ʻana i nā wafer holomua a me nā mea hana lithography.

- Hoʻonui ʻia ka Conductivity Thermal:Ke kaulike nei i ka ikaika a me ka hoʻokele wela, hāʻawi ʻo 7075 i kahi conductivity thermal ma kahi o 150 ~ 160 W / m · K, e hoʻokuʻu pono ana i ka wela i hana ʻia i ka wā o nā kaʻina hana semiconductor mana kiʻekiʻe me ka mālama ʻana i ka paʻakikī o ke kūkulu ʻana.

Ka Hana Machining Excellence & Nā Hiki Hoʻopilikino

ʻO kahi pōmaikaʻi nui o ka alumini 7075, ʻoi aku hoʻi i ka mahana T6, ʻo ia kona machinability maikaʻi loa no nā hana CNC kikoʻī. He loea kā mākou hui i ka hoʻololi ʻana7075 mau pā, nā kaola, a me nā paipui loko o nā ʻāpana semiconductor i hana ʻia me nā mīkini maʻamau, e hoʻohana ana i nā ʻano ʻoki maikaʻi o ka mea e hoʻokō ai i ka pololei kūlike ʻole:

- Hoʻopau ʻili kiʻekiʻe loa:7075 mau mīkini i nā hoʻopau ʻili laumania loa (Ra ≤ 0.4 μm) i ka wā e hoʻohana ai i nā mea hana carbide ʻoi a i ʻole PCD, e hoʻopau ana i ka pono no ka polishing lua a me ka hōʻoia ʻana i ka sila vacuum maikaʻi loa a me ke kūʻē ʻana i ka haumia o nā ʻāpana i nā wahi lumi maʻemaʻe.

- Nā hoʻomanawanui pololei loa:Hoʻopaʻa mau mākou i nā ʻae ʻana o ka dimensional a hiki i ±0.002 mm no nā hiʻohiʻona koʻikoʻi, me ka pololei geometric e pili ana i ka parallelism ≤ 0.005 mm a me ka flatness ≤ 0.003 mm, e hoʻokō ana i nā koi koʻikoʻi loa no nā semiconductor wafer chucks, nā mea paʻa electrode, a me nā liner chamber.

- Nā ʻAno Hoʻohālikelike Paʻakikī:Hoʻopane maikaʻi ka metala i ka mīkini wikiwiki, e ʻae ana i ka hana ʻana o nā ʻāpana paʻakikī, paia lahilahi, a kikoʻī loa me nā contours paʻakikī, nā lua hohonu, a me nā micro-features pono no nā lako semiconductor hou.

- Hoʻohālikelike ma hope o ka hana ʻana:ʻAe koke ʻo 7075 i nā ʻano hana ʻili like ʻole e koʻikoʻi no nā noi semiconductor, me ka anodizing paʻakikī, ka electroless nickel plating, a me ka passivation. Hoʻonui kēia mau hana i ke kūpaʻa ʻana i ka palaho, ka paʻakikī o ka ʻili (a hiki i ka 500 HV), a me ka non-conductivity, e pale ana i nā kinoea hana corrosive a me nā wahi etching plasma.

Nā Noi Pahuhopu ma ka ʻOihana Semiconductor

Ua hoʻolaha pono ʻia ka alumini 7075 ma ke kaulahao hana semiconductor, kahi i hiki ʻole ke kūkākūkā ʻia ka hana a me ka hilinaʻi:

1. Nā ʻāpana hana a me ka lawelawe ʻana o ka wafer:ʻO nā mea hoʻopau hopena kikoʻī, nā mea paʻa robot, nā mea lawe wafer, a me nā lima hoʻoili e pono ai ka ikaika kiʻekiʻe, ka inertia haʻahaʻa, a me ka hana ʻole o nā particulate.

2. Nā ʻAno Hana o ke Keʻena:ʻO nā paia o ke keʻena hakahaka kiʻekiʻe, nā papa hoʻolaha kinoea, a me nā kākoʻo kūloko e koi ana i ka paʻakikī o ke kūkulu ʻana ma lalo o ka hakahaka, ka conductivity thermal maikaʻi loa, a me ke kūpaʻa i ka pala.

No ke aha e koho ai i kā mākou huahana alumini 7075?

Ua hoʻolaʻa ʻia kā mākou ʻoihana i ka hoʻolako ʻana i ka semiconductor-grade7075 alumini ma nā ʻano pā, pā, a me nā paipu,i hoʻokō ʻia e kā mākou lawelawe mīkini kikoʻī i loko o ka hale. Hoʻopili mākou i nā kūlana honua e pili ana iā AMS 4167, AMS 4168, a me ISO 6362, e hōʻoiaʻiʻo ana ua noa kā mākou mau mea mai nā inclusions, porosity, a me nā koena stress. Hoʻomaʻamaʻa ʻia kēlā me kēia huahana i ka hoʻāʻo maikaʻi koʻikoʻi, me ka nānā ʻana o ka ultrasonic, ka hoʻāʻo paʻakikī, a me ka hōʻoia tensile e hōʻoia i ka hoʻokō ʻana me nā kūlana SEMI no nā mea semiconductor.

Ma ke koho ʻana i kā mākou mau hoʻonā alumini 7075, loaʻa i nā mea hana lako semiconductor kahi hoa hilinaʻi e hāʻawi ana i ke kūlike o nā mea, ka pololei o ka mīkini, a me ka ʻike loea. Hoʻomaopopo mākou ʻaʻole he koho ka hemahema o nā mea i loko o ka ʻoihana semiconductor, pili pololei ia i ka hua hana, ka manawa hana o nā lako, a ma ka hopena, ka hopena. Hōʻike ka alumini 7075 i ka piko o ka hoʻomohala ʻana i ka hui alumini, a ʻo ko mākou akamai i kēia mea, mai ka waihona maka a hiki i nā ʻāpana mīkini i hoʻopau ʻia, hoʻonoho iā mākou ma ke ʻano he mea hoʻolako hilinaʻi no nā lole semiconductor alakaʻi o ka honua a me nā OEM lako.

ʻO ke kūʻai ʻana i ka alumini 7075 he kūʻai ʻana ia i ka hana lōʻihi, ka hilinaʻi, a me ka pono. No nā noi semiconductor e koi ana i ka mea maikaʻi loa i nā mea kūkulu, ʻaʻole wale ka 7075 he koho, ʻo ia ke kūlana o ka ʻoihana.
