The Hatina WLBI by Cosmic is a robust wafer-level Burn-In and HTOL (High-Temperature Operating Life) solution designed specifically for power devices on wafers. This compact test chamber (560Ã-560Ã-550 mm) plugs into standard wafer probers, enabling full-wafer Burn-In without major equipment overhauls. Its high parallel throughput supports up to 1,600 test sites simultaneously, each operating at up to 1.2 kV and 2 mA-ideal for lifecycle and reliability testing of power technologies. The WLBI seamlessly integrates functional burn-in, HTGB (High-Temperature Gate Bias), and HTRB (High-Temperature Reverse Bias) test setups, offering a flexible and cost-effective package. Compact and easy to handle, the WLBI is engineered for cleanroom use and aligns with Cosmic's ovenless Burn-In philosophy-embedding heaters directly at each DUT for precise, low-power thermal control. This design reduces energy use, lowers footprint, and simplifies automation compatibility. In summary, the Hatina WLBI is a high-density, wafer-level Burn-In platform that delivers full-wafer reliability testing for advanced power semiconductors, combining high voltage, tight temperature control, and multi-site scalability in a compact, integration-friendly format-perfect for enhancing manufacturing efficiency and device confidence.
