The Osaka Type Thermal Stress Tester simulates thermal stresses that materials and components experience due to temperature fluctuations. It is designed to evaluate the reliability and lifespan of products by revealing defects such as cracking, delamination, solder fatigue, and material degradation. The instrument supports both thermal cycling and thermal shock tests, providing accelerated testing for quality assurance, R&D, and failure analysis.
