Waxyeelaha Dhamaadka Dhoobada ee Silicon Carbide (SiC) - Adkayn Sare oo loogu talagalay Maareynta Wafer Heerkulka Sare
Qalabka wax soo saarka dhammaadka dhoobada ee St.Cera's SiC waxaa laga sameeyay carbide silicon saafi ah (SiC content 99.72%, Si bilaash ah 0.05%) iyadoo la adeegsanayo walxaha dufcadda S1111. Waxay bixisaa sifooyin farsamo oo heer sare ah: xoogga dabacsanaanta 449 MPa (la cabbiray), modulus dabacsanaan 457 GPa (la cabbiray), iyo adkaanta Vickers 25-28 GPa (caadiga ah). Cufnaanta hoose (3.10-3.15 g/cm³, caadiga ah) waxay bixisaa adkaansho gaar ah oo sare, oo ku habboon robotyada wareejinta wafer-ka xawaaraha sare leh. Iyada oo leh hab-dhaqan kuleyl oo ah 120-150 W/m·K (caadiga ah) iyo isku-darka ballaarinta kulaylka ee 4.0-4.5 × 10⁻⁶/℃ (caadiga ah), qalabkan dhammaadka ah si wax ku ool ah ayuu u kala firdhiyaa kulaylka wuxuuna ilaaliyaa xasilloonida cabbirka inta lagu jiro maaraynta heerkulka sare (ilaa 1600-1700°C, ma jiro culays). Midabka madow/cawlan iyo nuugista biyaha eber waxay hubinayaan iswaafajinta qolka nadiifka ah.
Tilmaamaha(iyadoo lagu saleynayo warbixinta tijaabada SiC S1111 ee la bixiyay iyo qiimayaasha caadiga ah)):
| Hantida | Qiimaha |
| Alaab | SiC (99.72% SiC, 0.05% Si Bilaash ah) |
| Midab | Madow/Cagaar |
| Cufnaanta | 3.10–3.15 g/cm³ |
| Nuugista Biyaha | 0% |
| Xoogga Dabacsanaan | 449 MPa (celcelis ahaan) |
| Adkaanta Jabka | 3.12 MPa·m¹/² (celcelis) |
| Modulus Laablaaban | 457 GPA |
| Adkaanshaha Vickers | 25–28 GPA |
| Qaboojinta Kulaylka (25°C) | 120–150 W/m·K |
| CTE (25–1000°C) | 4.0–4.5 × 10⁻⁶/℃ |
| Heerkulka ugu badan ee Isticmaalka (ma jiro culays) | 1600–1700°C |
Codsiyada:
● Maareynta wafer-ka heerkulka sare leh (ka dib-anneal, RTP, epitaxy)
● Qolalka balaasmaha ee u baahan iska caabinta nabaad-guurka oo sarreeya
● Robot-yada xawaarahooda sare leh (fudud, qallafsanaan sare)
Wax soo saarka:
Sintering budada SiC → shiididda saxda ah ee CNC ee astaanta gacanta iyo sifooyinka rakibidda → duubista dusha sare → nadiifinta ultrasonic. 100% kormeerka cabbirka iyo tijaabada daadinta helium ee codsiyada faaruqinta.
Xakamaynta Tayada:
● Kormeerka CMM ee dhererka, ballaca, iyo fidsanaanta
● Tijaabada xoogga dabacsanaanta dufcaddiiba (heerka warbixinta tijaabada)
● Kormeer muuqaal ah oo lagu sameeyay mikroskoob si loo ogaado cilladaha dusha sare
Faa'iidooyinka ka badan Alumina ama Birta:
● 2× modules-ka dabacsan ee sare (457 vs ~380 GPa ee alumina) - leexasho yar
● 3× koronto-qaadis heer sare ah - kuleyl dhaqso badan oo kala firdhisan
● Waxay u adkaysataa >1600°C marka loo eego 800°C ee alumina hawada
● Cufnaanta ka hooseysa birta - 40% dhimista miisaanka
Habayn:
Dhererka 150–450 mm, qaababka caarada (qabashada geeska, Bernoulli, fidsan), qaababka flange-ka ee lagu rakibayo sawirka OEM.
*Dhammaan xogta farsamada ee kor ku xusan waxay ka timid warbixinta tijaabada ee la bixiyay (dufcaddii S1111). Qiimaha kulaylka iyo adkaanta ayaa caadi u ah darajadan SiC; fadlan nala soo xiriir si aad u hesho shahaado gaar ah.*
