ESS Rapid-Rate Temperature Change Test Chamber

The chamber is built to create faster temperature transitions than standard temperature chambers. Rapid temperature cycling helps accelerate expansion and contraction stress in components and assemblies.

Key advantages: selectable temperature change rates from 5℃ to 25℃/min, repeatable thermal stress cycles, stable test control, efficient defect screening, suitable for production reliability checks, and practical use in ESS programs.

The selectable ramp-rate design helps users match screening intensity to product type, sample heat load, reliability target, and test procedure.

For an ESS chamber, temperature range alone is not enough. The temperature change rate, load condition, airflow, recovery performance, and sample heat capacity all affect real test results.

Key factors: temperature range, required ramp rate, heating rate, cooling rate, chamber volume, sample load, airflow uniformity, recovery time, dwell time, cycle count, product temperature monitoring, cable ports, and data recording.

Selection should be based on the actual sample load, not only empty-chamber performance.

Rapid temperature change testing is useful for products that need early defect detection, process screening, or reliability improvement before shipment.

Typical applications: PCBs, semiconductors, sensors, connectors, relays, control modules, automotive electronics, communication equipment, aerospace electronics, power modules, industrial controllers, and small assemblies.

Failure risks evaluated: solder joint weakness, connector instability, PCB micro-cracks, material fatigue, coating defects, insulation problems, intermittent electrical failure, and assembly stress caused by repeated temperature cycling.

The chamber uses programmable control for temperature profiles, dwell time, cycle count, alarms, and optional data recording. Strong airflow and refrigeration capacity are important for achieving repeatable rapid temperature changes under real sample load.

SANWOOD adopts advanced cooling balance technology and coolant flow rate control technology to improve refrigeration efficiency. Energy saving can reach more than 30% depending on chamber configuration, test profile, ambient conditions, and operating mode.

System features: programmable touchscreen controller, rapid heating and cooling control, multi-step cycling profiles, optimized airflow, high-performance refrigeration system, cooling balance control, coolant flow rate control, optional RS232 / RS485 / Ethernet communication, optional PC monitoring, optional data logging, and alarm protection for abnormal operation.

Final configuration should be confirmed according to sample size, load, target ramp rate, temperature range, airflow requirement, energy-saving target, and test duration.

The chamber can be configured to support test conditions related to ESS and temperature cycling methods, including IEC 60068-2-14 change of temperature, JESD22-A104 temperature cycling, MIL-STD-810 environmental methods, and customer-specific reliability screening procedures.

Final compliance depends on the complete test method, sample type, sensor setup, calibration status, temperature change rate, dwell time, operating procedure, and third-party assessment.

Customization options: temperature range, temperature change rate configuration, chamber volume, sample rack, cable ports, product temperature monitoring, communication and data recording, refrigeration system configuration, energy-saving control configuration, and power supply by destination country.

SANWOOD Technology can provide model selection support, customization guidance, installation assistance, maintenance, repair, and technical service according to project requirements.
