ʻO ka mea hoʻopau hopena keramika Alumina me nā kahawai Vacuum i hoʻohui ʻia
Hoʻohui ka mea hoʻoheheʻe hopena alumina a St.Cera i nā kahawai vacuum i hana pololei ʻia a me nā lua omo pololei i loko o ke kino alumina maʻemaʻe 99.8%. Hoʻopau kēia hoʻolālā i nā pads vacuum waho, e hiki ai ke kiʻi pololei i ka wafer me ka ikaika paʻa like. ʻO ka ikaika flexural kiʻekiʻe o ka mea (361 MPa) a me ka paʻakikī (16 GPa) e hōʻoia i ka paʻa lōʻihi o ka dimensional ma lalo o nā pōʻaiapuni vacuum i hana hou ʻia. Mālama ʻia ka pālahalaha ma ka ʻāpana pad i loko o 10 μm, e pale ana i ke kaumaha wafer a me ka haki ʻana. Aia nā awa vacuum ma ka flange hoʻopaʻa hope no ka hoʻohui maʻalahi me nā lima robot OEM.
Nā kikoʻī(ma muli o 99.8% Al₂O₃):
| Waiwai | Waiwai |
| Mea Hana | 99.8% Alumina (ʻAiwi ʻelepani) |
| Ka nui o ka paʻa | 3.93 g/cm³ |
| Ikaika Flexural | 361 MPa |
| Paʻakikī Vickers | 16 GPa |
| Modulus o Young | 380 GPa |
| Hoʻonui Wela | 7.2×10⁻⁶/℃ |
| Ka pālahalaha o ka pā | ≤10 μm |
| Ka laulā o ke kahawai Vacuum | 0.5–2.0 mm |
| Mahana Hana Loa | 800°C |
Nā noi:
● ʻOhi ʻana i nā wafers lahilahi a i ʻole nā wafers i ʻōwili ʻia me ka vacuum
● Ka lawelawe pololei ʻana i ka wafer me ka ʻole o ka paʻa ʻana i ka lihi
● Hoʻoili ʻana o ke kelepona lā a me ka substrate LED
Hana ʻana:
ʻO ka alumina sintered blank → ʻEli CNC 5-axis o nā kahawai vacuum a me nā lua → lapping ʻili → hoʻomaʻemaʻe ultrasonic → hoʻāʻo leaka helium. Hoʻāʻo ʻia kēlā me kēia effector 100% no ke ʻano like o ka vacuum.
Nā Pōmaikaʻi:
● ʻAʻohe pale hoʻomaʻemaʻe waho (hoʻemi i nā kumu ʻāpana)
● Pale ke kaomi paʻa like i ka māka wafer
● ʻAʻohe kemika a kūlike me ka lumi maʻemaʻe
