Zida za ESD-Safe Alumina Ceramic Zothandizira Kusamalira Wafer Mosasinthasintha
Ziwalo za St.Cera's ESD (electrostatic discharge) safe alumina ceramic zimapangidwa kuchokera ku 99.8% high-purity Al₂O₃ yokhala ndi resistivity yapamwamba ya 10⁶–10⁹ Ω/sq, yomwe imapezeka kudzera mu njira yopangira doping kapena coating. Ziwalozi zimachotsa bwino mphamvu yokhazikika, kuteteza kuwonongeka kwa magetsi ku ma wafers ndi zida zina za semiconductor. Chipangizo choyambira chimasunga mphamvu yake yopindika (361 MPa), kuuma (16 GPa), ndi mphamvu ya dielectric (15×10⁶ V/m). Ziwalo za ceramic zotetezeka za ESD zimaphatikizapo ma end effectors, ma lift pini, ma guide rails, ndi zida zapadera za FAB automation.
Mafotokozedwe(kutengera 99.8% Al₂O₃ ndi chithandizo cha ESD):
| Katundu | Mtengo |
| Zinthu Zoyambira | 99.8% Aluminiyamu |
| Kusakhazikika Pamwamba (ESD) | 10⁶–10⁹ Ω/sikweya |
| Kuchulukana | 3.93 g/cm³ |
| Mphamvu Yosinthasintha | 361 MPa |
| Kuuma kwa Vickers | 16 GPa |
| Modulus ya Achinyamata | 380 GPa |
| Kuwonjezeka kwa Kutentha (25-1000°C) | 7.2×10⁻⁶/℃ |
| Kutentha Kwambiri Kogwira Ntchito | 800°C |
| Mphamvu ya Dielectric (yambiri) | 15×10⁶ V/m |
Dziwani: Kukana kwa ESD pamwamba sikuperekedwa m'matebulo azinthu zomwe zaperekedwa. Mtundu womwe uli pamwambapa ndi muyezo wamakampani opanga zinthu zosakaniza zadothi. Chonde titumizireni malipoti oyesa.
Mapulogalamu:
● Zothandizira zotetezera za ESD pakusamutsa wafer
● Mapini oyambira pansi ndi zida za ESD mu zida za FAB
● Yesani masoketi a zipangizo zomwe sizimasinthasintha
● Zipangizo zoyeretsera m'chipinda chotsukira komwe kulamulira kosasinthasintha ndikofunikira kwambiri
Kupanga ndi Ubwino:
Kukonza alumina wamba + ESD surface treatment → surface resistivity imayesedwa pa ANSI/ESD STM11.11. Gawo lililonse limayesedwa 100% ndi concentric ring electrode.
Ubwino:
● Zimaletsa kutayika kwa zokolola zokhudzana ndi ESD
● Imasunga mphamvu ya makina a ceramic komanso kukana mankhwala
● Palibe kupanga tinthu kuchokera ku kutulutsa kosasinthika
