Product Overview and 2025 Market Relevance

Industrial burn-in and reliability test platforms purpose-built for silicon carbide (SiC) power modules are critical to deliver dependable performance in Pakistan’s textile, cement, steel, and emerging industrial sectors. These platforms execute high-temperature reverse bias (HTRB), high-temperature gate bias (HTGB), and power cycling with precise thermal and electrical stress control, ensuring that SiC modules achieve long lifetimes under harsh heat, dust, and vibration.

In 2025, plants in Punjab and Sindh are accelerating upgrades to SiC-based rectifiers, inverters, DC drives, and furnace converters. To validate long-term reliability and reduce warranty risk, quality assurance workflows require standardized screening and life testing aligned with IEC and JEDEC practices. SiC reliability platforms help manufacturers and integrators screen out infant mortality, characterize wear-out mechanisms, and certify modules with junction temperatures up to 175°C, power densities >8 kW/L, and thermal resistance <0.2°C/W. The result is >50% failure-rate reduction in the field, >98% conversion efficiency maintained over life, and service intervals extended to once every two years—directly supporting 2–3 year ROI models and ISO 50001/14001 objectives.

These platforms are engineered for high throughput and data integrity, with automated test scheduling, environmental enclosures, and integration to LIMS/MES systems. Detailed reports support IEC 62477-1 (safety of power electronic equipment), IEC 61000 (EMC test environments), and IEC 60747 (semiconductor devices) documentation requirements for local acceptance.
