Alter Technology TÜV NORD

Alter Technology provides comprehensive environmental stress testing and screening capabilities:

• HALT & HASS Testing: Highly Accelerated Life Testing (HALT) and Highly Accelerated Stress Screening (HASS) protocols combining extreme multi-axis vibration, rapid thermal transitions, and electrical stresses to identify latent design flaws and screening limits.
• Thermal Cycling & Shock: Controlled thermal cycling across extreme temperature margins to evaluate mechanical fatigue, solder joint cracking, CTE mismatch, and package integrity; thermal shock testing with rapid liquid-to-liquid or air-to-air transitions.
• Accelerated Stress Testing: High Accelerated Stress Test (HAST), High Temperature Operating Life (HTOL), and burn-in testing under electrical bias and elevated thermal environments.
• Environmental Simulations: Climatic chambers for humidity, salt spray, solar radiation simulation, altitude/low-pressure testing, and thermal vacuum cycling.
• Component Screening & DPA: Destructive Physical Analysis (DPA), internal visual inspection, acoustic microscopy (C-SAM), X-ray radiography, bond pull, and die shear testing in accordance with MIL-STD-883, MIL-STD-202, ECSS, and ESCC standards.
