The TestEQ ETH²-series HALT / HASS test chamber is an integrated environmental and multi-axis vibration test system. It accelerates failure discovery during product development and controlled production screening by combining rapid temperature transitions with multi-axis repetitive shock vibration, helping reliability engineers identify design weaknesses, determine operating and destruct limits, and evaluate robustness under combined stress.
Applications
- Design-margin discovery (HALT) and production screening (HASS)
- Electronics, PCB assemblies and interconnects
- Automotive and EV power electronics
- Aerospace, defense and communication equipment
- Components and modules where latent defects must be exposed early
Configuration and features
- Capacity 215 to 1100 L (customizable).
- Temperature range -100 °C to +200 °C.
- Rapid temperature transition: up to 100 °C/min (standard support from 30 °C/min to 70 °C/min as an option).
- Cooling method: liquid nitrogen (LN₂).
- Vibration system: 6-DOF pneumatic repetitive shock.
- Vibration frequency range 5 to 10,000 Hz.
- Vibration acceleration ≥ 100 g under no-load condition.
- Vibration range 5 to 100 GRMS; vibration overshoot ≤ 2 GRMS.
- Consistency ≤ 20 %.
- Multi-axis vibration is integrated with the thermal system; the DUT can be monitored for functional degradation, intermittent failures and structural weaknesses.
- Extended vibration range available up to 70 Grms.
- Power supply AC 380 V, 3-phase, 5-wire, 50/60 Hz.
- Patent number CN201520670413.0.

Model designations include the ETH² series (for example ETH²-460, ETH²-610, ETH²-762, ETH²-910 and ETH²-1213). Temperature ramp rate and vibration performance should be evaluated under the intended DUT load and fixture configuration; unloaded maximum specifications may not represent actual test performance.
Standards
HALT and HASS are reliability engineering methodologies rather than a single compliance test defined by one universal standard. Commonly related standards and guidelines include IEC 60068 series (IEC 60068-2-14, IEC 60068-2-6, IEC 60068-2-27), MIL-STD-810, MIL-STD-883, MIL-STD-202, RTCA DO-160, ISO 16750, SAE J1211, JEDEC JESD22, IEC 60749, IPC reliability requirements, and ISO and NASA reliability guidance.
