Akụkụ seramiiki alumina nke ESD-Chekwa maka njikwa Wafer na-adịghị agbanwe agbanwe
A na-emepụta akụkụ seramiiki alumina dị nchebe nke St.Cera's ESD (electrostatic discharge) site na 99.8% dị ọcha nke Al₂O₃ nwere nguzogide elu ahaziri nke 10⁶–10⁹ Ω/sq, nke a na-enweta site na usoro doping ma ọ bụ mkpuchi nkeonwe. Akụkụ ndị a na-ewepụ chajị kwụ ọtọ nke ọma, na-egbochi mmebi electrostatic na wafers na ngwaọrụ semiconductor dị nro. Ihe ndabere ahụ na-ejigide ike flexural dị elu ya (361 MPa), ike (16 GPa), na ike dielectric (15×10⁶ V/m). Akụkụ seramiiki nchekwa ESD gụnyere ihe ndị na-eme ihe njedebe, pin elu, rail nduzi, na ihe ndozi ahaziri maka akpaaka FAB.
Nkọwapụta(dabere na 99.8% Al₂O₃ yana ọgwụgwọ ESD):
| Akụ na ụba | Uru |
| Ihe Ntọala | 99.8% alumina |
| Nguzogide Elu (ESD) | 10⁶–10⁹ Ω/sq |
| Njupụta | 3.93 g/cm³ |
| Ike nke Flexural | 361 MPa |
| Ike Vickers | 16 GPA |
| Modulu nke Young | 380 GPA |
| Mgbasawanye Okpomọkụ (25-1000°C) | 7.2 × 10⁻⁶/℃ |
| Oke okpomọkụ ọrụ kachasị | 800°C |
| Ike Dielectric (nnukwu) | 15 × 10⁶ V/m |
Rịba ama: E tinyeghị ihe mgbochi elu ESD na tebụl ihe onwunwe enyere. Usoro dị n'elu bụ ọkọlọtọ ụlọ ọrụ maka seramiiki na-agbasa. Biko kpọtụrụ anyị maka akụkọ nnwale.
Ngwa:
● Ihe ndị na-eme ka ESD dị nchebe maka nnyefe wafer
● Ntụtụ ala na ihe ndozi ESD na akụrụngwa FAB
● Nwalee oghere maka ngwaọrụ ndị nwere mmetụta na-anaghị agbanwe agbanwe
● Ngwaọrụ nhicha ụlọ ebe njikwa kwụ ọtọ dị oke mkpa
Mmepụta na Ogo:
Nhazi alumina nkịtị + ọgwụgwọ elu ESD → iguzogide elu nke a tụrụ dịka ANSI/ESD STM11.11 si dị. A na-anwale akụkụ ọ bụla 100% site na iji electrode mgbanaka concentric.
Uru:
● Na-egbochi mfu mkpụrụ metụtara ESD
● Na-ejigide ike mekaniki nke seramiiki na iguzogide kemịkalụ
● Enweghị mmepụta ihe sitere na mwepụ na-agbanwe agbanwe
