Productoverzicht en relevantie voor de markt in 2025

Silicon carbide (SiC) device burn-in and automated test equipment (ATE) provide the high-temperature, high-voltage stress environments required to screen early-life failures and verify lifetime under harsh conditions. Compared with traditional silicon, SiC’s higher electric field strength and elevated junction temperatures demand specialized ovens, power stress fixtures, parametric measurement units, and safety-compliant automation. Sicarb Tech’s burn-in/ATE platforms qualify SiC MOSFETs, Schottky diodes, power modules, and integrated power stages at 175–200°C, simulating real-world stress in Pakistan’s textile, cement, staal, and data-critical sectors.

Why it matters for Pakistan in 2025:

• Facilities experience ambient temperatures up to 45°C and frequent voltage sags/swells; devices must be screened for robustness before deployment.
• UPS, VFDs, PV inverters, and BESS require predictable reliability to lower OPEX and avoid unplanned outages.
• Localized qualification capacity reduces lead times and import dependency, supporting faster rollouts for industrial modernization and the digital economy.
• ESG and energy-efficiency targets amplify the need for long-lived, high-efficiency SiC platforms proven through rigorous burn-in and automated reliability testing.

Sicarb Tech offers turnkey burn-in systems—HTRB, HTGB, power cycling, dynamic switching stress—and automated parametric ATE with data logging and analytics. Systems are adaptable to RBSiC/SSiC-based packaging, ensuring realistic thermal paths during stress.

Belangrijkste voordelen en bewezen voordelen

• Early-life failure screening: HTRB/HTGB and HTOL protocols capture infant mortality before shipment, lowering field RMAs and downtime.
• Lifetime acceleration with data: Power cycling and switching stress map mission profiles to accurate lifetime predictions under 45°C ambient and dusty conditions.
• Faster time-to-market: Automated recipes and fixtures reduce engineering cycles; local testing shortens qualification lead times for Pakistani projects.
• Production-grade safety: HV interlocks and arc detection ensure operator safety and audit-ready processes.
• Actionable analytics: Parametric drift, leakage trends, and Zth changes trigger corrective actions in packaging, assembly, or supplier lots.
