Babban Tsarkakken Alumina Ceramic Core don Semiconductor Fixtures
An samar da tsakiyar yumbu na St.Cera daga tsarkin Al₂O₃ mai ƙarfi 99.8%, yana ba da ƙarfin dielectric na musamman (15×10⁶ V/m), kwanciyar hankali na zafi har zuwa 1600°C, da juriya ga rarrafe a ƙarƙashin kaya. Ana amfani da waɗannan tsakiya a matsayin abubuwan gini a cikin kayan aiki masu zafi, tushen hita, layin ɗakin plasma, da masu hana wutar lantarki. Babban taurin kayan (16 GPa) da ƙarancin shan ruwa (0%) suna tabbatar da aminci na dogon lokaci a cikin mawuyacin yanayi.

Aikace-aikace:
- · Tushen dumama don masu karɓar wutar lantarki na epitaxial
- · Layin ɗakin plasma da faranti na murfin
- · Masu hana wutar lantarki mai ƙarfin lantarki
- · Tushen kayan aiki don robots ɗin sarrafa wafer
Masana'antu:
Matsi na Isostatic → injin kore → sintering a 1600°C → Niƙa CNC zuwa girman ƙarshe (±0.01 mm haƙuri). Ana duba kowane core ta hanyar CMM da gano lahani na ultrasonic.
Tabbatar da Inganci:
An tabbatar da ingancin ISO 9001: 2015. Gwajin shigar da rini don fasa saman; gwajin ƙarfin dielectric bisa ga ASTM D149.
Afa'idodi akan sauran tukwane:
- · Ƙarfin dielectric mafi girma fiye da zirconia (15 vs <10×10⁶ V/m)
- · Ƙananan farashi fiye da SiC don aikace-aikacen da ba na plasma ba
- · Kyakkyawan juriya ga halogens (banda HF)
Siffofi na Musamman:
Silinda, sandunan murabba'i, faranti, ko siffofi masu rikitarwa. Mafi ƙarancin girman fasali 0.5 mm.
Tuntube mu don ƙirar asali na musamman da tallafin kwaikwayon zafi.
