The TestEQ mixed gas corrosion test chamber exposes electronic components, contacts and assemblies to a controlled flowing mixture of corrosive gases, reproducing the corrosive atmospheres that cause contact and interconnection failures in service. The test is intended for the IEC 60068-2-60 flowing mixed gas method.
Applications
- Electronic components, connectors and contacts
- PCB assemblies, plated through-holes and interconnects
- Equipment used in industrial, automotive and telecommunication environments
- Reliability and qualification testing for corrosion resistance
Configuration and features
- Flowing mixed gas method for IEC 60068-2-60 corrosion testing.
- Gas concentration adjustable from 0.1 ppm to 25 ppm (range varies by gas type).
- Controlled gas mixture, temperature and humidity for repeatable exposure conditions.
- Supports simultaneous dosing of up to four gases (H₂S, SO₂, Cl₂ with N₂ carrier gas; NO₂ with synthetic air) for multi-pollutant interaction studies.
- Acrylic (PMMA) viewing window for real-time monitoring of specimens.
- Pressure monitoring system and gas sampling port for operator safety.
- Integrated air exchange module for consistent gas distribution.
- Programmable test profiles for batch or continuous exposure.
- The equipment can be evolved into a sulfur dioxide corrosion test chamber and a hydrogen sulfide corrosion test chamber.
