Environmental Stress Screening (ESS)
BIA Climatic ESS Chamber
Fast Temperature Ramp for Accelerated Environmental Stress Screening
Environmental Stress Screening (ESS) is a controlled testing process used to identify latent defects and potential weaknesses before products reach the field. By applying repeated and accelerated thermal stresses, ESS can help reveal weaknesses in components, solder joints, materials and assemblies.
With fast temperature ramp rates up to 25 K/min, the BIA Climatic ESS Chamber enables rapid temperature transitions, helping accelerate thermal cycling and improve screening efficiency.
Fast Ramp Rate & Wide Environmental Range
The chamber provides a wide operating range for demanding reliability applications:
- Temperature: -70°C to +180°C
- Humidity: 10–98% RH
- Chamber Volume: 300 L, 450 L, 650 L, 1,000 L, 1,500 L and 2,000 L
- Ramp Rate: 5 K/min | 10 K/min | 15 K/min | 20 K/min | 25 K/min
Energy-Efficient Refrigerant Control
Fast temperature changes do not have to mean excessive energy consumption. BIA Climatic’s advanced refrigerant control system intelligently manages refrigerant flow and cooling capacity according to operating conditions.
This helps maintain fast ramp performance and stable temperature control while reducing unnecessary compressor operation and energy consumption, supporting lower operating costs over the chamber’s service life.
Key Features
- Energy-efficient refrigerant control
