The Screening Systems, Inc. QRS-410T is a combined vibration and thermal environmental stress screening (ESS) system for Highly Accelerated Life Testing (HALT) and Highly Accelerated Stress Screening (HASS). It identifies latent defects in materials, designs, and production processes through accelerated stress application, reducing field failures and associated warranty costs. The system accommodates printed circuit boards, small subassemblies, and complete systems within its payload constraints.
