What is thermal cycling?

Thermal cycling is commonly used to evaluate product reliability performance, a high level thermal cycle chamber ensure performance, functionality, and safety of your products.

Simply speaking, thermal cycling, also called as thermocycling, determines the durability and breaking points of products, new materials, or components under alternating high and low temperatures environment, these continuous temperature changes simulate the normal use conditions that products may encounter in the real life, thermal cycling is used to catch early-stage defects, such as breaking, cracking, short-circuit, and warping phenomena.

Thermal cycling is similar to thermal shock test. The main difference between the two is found in how rapid those temperature changes take place. Thermal shock test exposes products in extreme high temperatures, then transfer to extreme low tempoeratures very quickly while temperature cycling is more gradual.

How does a Environmental Temperature Chamber work?

Environmental Temperature Chamber or temperature cycling chamber, adopts forced air convection inside the testing zone to perform heating and cooling tests, the purpose is to evaluate the reliability of a product under extreme temperatures.

To realize temperature control, the test chamber should be able to carry out two functions: heating and cooling, uniform temperature also must be evenly distributed inside the testing area, Climatest Symor® makes it possible to achieve a high degree of temperature uniformity in the whole testing area.

Environmental Temperature Chamber adopts mechanical cooling system and mechanical heating system to conduct testings on products:

Mechanical heating system consists of electric heating elements positioned near the ventilation system, so that the heated hot air is delivered into the testing zone from air inlet, then come out from air outlet, meanwhile, there are centrifugal fans located at the back of the air inlet, so as to blast the hot air to reach better uniformity.

Mechanical cooling system consists of a closed circuit system, with the following main components:

·Control valve

·Condensor

·Evaporator

·Compressor

The refrigeration system in a thermal test chamber is classified to be single stage and double stage, the single stage is adopted with temperature -40℃ and above, and double stage (also called cascade system) is with temperature below 40℃.

Application:

Environmental Temperature Chamber is widely applied in below industries:

Electronic& Semiconductor Industry:

The inherent reliability of electronic components is decided by the reliability design scheme. During the manufacturing process, due to fluctuations in human factors or raw materials, process parameters, and equipment conditions, the final product cannot all achieve the expected reliability. In each batch of finished products, there are always hidden defects, which manifest as early failure under certain stress conditions.

Therefore, it is necessary to take measures to screen these electronic components with initial failure as much as possible before they are installed on the machine, and for this purpose, Environmental Temperature Chamber is one of the screening equipments in early quality control process:

1. High temperature test of Environmental Temperature Chamber

High temperature screening is commonly applied on semiconductor devices, which are stored at high temperature for 24 to 168 hours. Most of the failures of electronic components are caused by surface contamination, poor bonding, and defective oxide layers, which are closely related to high temperature.

The thermal stress and screening duration of various electronic components should be appropriately selected to avoid new failure mechanisms. High-temperature screening is simple, inexpensive, and can be implemented on many components.

2. Low temperature test of Environmental Temperature Chamber

How often do electronic components fail at low temperature? Most electronic components have a working temperature range, beyond this range, they will fail or performance declines, the change of temperature has a great influence on the conductivity, voltage, and current of the semiconductor devices. Nowdays, a chip often contains millions of transistors and other components,the accumulation of every small deviation have a huge impact on their final performance, thermal test chamber simulates low temperature testing condition, and help manufacturers collect data for reference in all above situation.

3. Temperature cycling test of Environmental Temperature Chamber

Due to heat expansion and cold contraction principle, electronic devices will encounter different ambient temperature conditions during use, and those with poor thermal resistance are prone to failure, Environmental Temperature Chamber simulates temperature cyclings between extreme high and low temperatures, which can effectively eliminate products with thermal performance defects.

Automobile Industry:

Environmental Temperature Chamber is one of the most crucial environment simulation equipments in automobile industry, products are experiencing a "torture" through environmental testing, automobile parts are tested rigorously, problems are explored and initial product design plans are repeatedly revised, so as to continuously improve quality.

1) High temperature test: The high temperature environment causes thermal effects, which will bring softening, expansion and evaporation, gasification, cracking, melting and aging of automobile parts, then automobiles will have mechanical breakdown, dealing failures, poor insulation of circuit systems, and more.

2) Low temperature test: The low temperature environment causes physical contraction, oil solidification, mechanical strength reduction, material brittlement, loss of elasticity and ice and more, then the automobile will appear cracking, mechanical failure, wear increase, sealing failure and insulation faults of circuit system.

3) Damp heat test: The ambient humidity causes corrosion on the metal surface, leading to material deterioration, electrical strength and insulation resistance reduction.

Plastics Industry:

Plastic products are everywhere in our daily life, involving in home appliances, bottles and containers, automobile parts, etc. For example, plastic bottles/bags have the advantages of simple process, material saving, and less space in the circulation process, and have been widely used in product packaging, especially food and beverage packaging.

However, changes in temperature and humidity affect the performance of plastic bottles/bags, they become soft at high temperatures, and hard/brittle at low temperatures; high relative humidity can weaken organic materials, and moisture can condense inside the package, causing corrosion or other damage, plastic bottles/bags have weak resistance to unfavorable factors such as temperature and humidity during circulation. To improve quality and strengthen competitiveness, plastic products manufacturers now pay much attention to the reliability testing of their products in the R&D stage.

Environmental Temperature Chamber provides an economical solution for a variety of testing requirements, which helps companies to find potential defects of their products in a short time, and provides a good data reference for the improvement of their product quality.

Moreover, temperature test cabinet is also applied in Communication, Pharmaceutical, Aerosapce, Military, Packaging industries, different tests are carried out according to customers’ specific requirement.

Packaging & shipment of Environmental Temperature Chamber

First step: Wrap thin film onto the whole Environmental Temperature Chamber for waterproof and dustproof purpose.

Second step: Bind bubble foam on Environmental Temperature Chamber tightly, and then cover the machine with a big plastic bag.

Third step: Put Environmental Temperature Chamber into a reinforced polywood case with pallet at bottom.

The packaging is sturdy enough to withstand bumpy sea and rail transport and ensure the product is delivered safely to the customers.

Environmental Temperature Chambers are commonly shipped by Sea, Road and Railway, Climatest Symor® helps to make vessel booking for customers, and fully asist customers’ specific shipping requirements, different incoterms are available, like EXW, FOB, CIF, DDU and DDP.
