I. Product Applications
Suitable for cold resistance testing of complete electrical/electronic products and components, as well as adaptability testing under rapid or gradual temperature changes. Particularly applicable for Environmental Stress Screening (ESS) testing of electrical/electronic products.
Utilizing temperature acceleration techniques (cyclic testing between upper/lower limit temperatures causing alternating expansion/contraction) to generate thermal stress/strain, accelerating latent defects in products (material flaws, process defects, workmanship issues). This prevents product failures during actual environmental stress exposure, significantly improving shipment quality and reducing repair frequency.
II. Product Features
