Environmental Stress Screening Rapid Rate Chambers Climatic Test Machine
Reliability testing is necessary to ensure your products meet the standards and the expectations of consumers. Reliability testing gives you peace of mind knowing that your products look and perform well before they reach the market. It's a good way to earn customers' trust and avoid costly effects of quality and reliability issues.
Applications
Environmental stress screening (ESS) refers to the process of exposing a newly manufactured or repaired product or component (typically electronic) to stresses such as thermal cycling and vibration in order to force latent defects to manifest themselves by permanent or catastrophic failure during the screening process. The surviving population, upon completion of screening, can be assumed to have a higher reliability than a similar unscreened population.
ESS can be performed as part of the manufacturing process or it can be used in new product qualification testing.
Standards Implemented and met
GB10592-89 Technical requirements for high and low temperature test chamber
GB2423.1-1989 Low temperature test
GB2423.2-1989 High temperature test mode
Features
Rational Construction and fast cooling rate
Frequency conversion control of wind speed.
Adopts international brand of imported parts for cooling system to improve operation reliability
Touch screen controller, friendly Man-Machine interface and safety device to ensure simple operation and easy maintenance.
Features of Different Cooling Mode for thermal shock chambers:
Since the cold chamber need huge cooling capacity for shocking, the chamber's cooling mode is often designed as air-cooled or water-cooled.
Air-cooled type need installation environment:
The room must be equipped with exhauster and air conditioner to make sure heat dissipation timely.
It's applied to small power products and cool areas.
Water-cooled type need installation conditions:
The customer must prepare water pipe and water tower (located outside) accordingly.
The water must be pure, or it will block the pipes and result in some maintenance trouble with time going.
It's often applied to large system with the features of better heat dissipation, longer service time, low noise but slightly higher price if count the fee of water tower and water pipes.
