Application of benchtop temperature humidity cabinet

Electronic& Semiconductor Industry:

The inherent reliability of electronic components depends on 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.

Moreover, electronic components have very strict requirements on temperature and humidity conditions, and the influence is very huge. Therefore, the benchtop temperature and humidity chamber is often used in the electronics industry. For instance, Are the circuits can meet the required temperature? Because the ambient temperature increases by 10℃, the life of the electronic components is reduced by about 30%-50%, and at least 10%.

So it is necessary to take measures to test these electronic components with initial failure as much as possible before next assembly, and for this purpose, benchtop temperature humidity cabinet is one of the fundamental testing equipments in early quality control process:

1. High temperature storage of benchtop temperature humidity cabinet

High temperature screening is commonly used 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 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. Temperature circulation system of benchtop temperature humidity cabinet

Due to heat expansion and cold contraction principle, electronic devices will encounter different ambient temperature conditions during use, and components with poor thermal resistance are prone to failure, portable thermal chamber simulates temperature cycles between extreme high temperature and extreme low temperature, which can effectively eliminate products with thermal performance defects. The commonly used screening conditions for components are -55 to +125℃, and 5 to 10 cycles.

3. Temperature humidity cycling of benchtop temperature humidity cabinet

benchtop temperature humidity cabinet tests the adaptability of products in use or storage under different environment conditions, because it will directly or indirectly affect peformance of products, the chamber provides useful data for design, production and use, and also expose problems in product design, raw materials, and manufacturing processes.

Automobile Industry:

Under the conditions of low temperature, high temperature, temperature and humidity cycling, the benchtop temperature and humidity chamber conducts environmental simulation tests, to check the physical changes of the products , and judges whether the performance can still meet the predetermined requirements through testing, so as to provide product design, improvement, identification reference.

What temperature and humidity tests should be done for autoparts?

1) High temperature test: The high temperature environment produce thermal effects, which will cause softening, expansion and evaporation, gasification, cracking, melting and aging of automobile parts (such as airbag, windshield washer system, brake hose, plastic 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 auto parts 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.

LED lighting Manufacturing Industry:

Light Emitting Diode (LED) is mostly used for indicator lights, lighting, display panels in home appliances and industry, it has the advantages of high efficiency and long service life. However, a certain service life should be assessed in the early development stage, this can be obtained through the environmental reliability test, the common equipments are temperature humidity chamber, temperature chamber, thermal shock chamber, through setting the temperature,humidity and cycles to proceed lifespan test, such as 85℃ / 85%, 60℃/ 85%, 500 hours, to evaluate whether the performance meets the quality standards or not.

LED-related products, such as OLED display modules, need to follow below principles when using a temperature humidity chamber:

1. Considering the product life cycle, analyze the type of environment encountered during production, transportation and storage.

2. Analyze the environmental factors that have the greatest impact on product performance, and select it for testing.

3. Collect and analyze the extreme climatic conditions encountered in the whole life cycle.

4. Analyze the characteristics of the product, in order to accelerate the assessment of environmental impact, extreme climatic conditions can be selected, such as damp heat test.

5. The duration of the test is closely related to the product type, structure, weight, etc.

In the LED industry, it is necessary to use the temperature humidity chamber for testing. These tests are connected together. If the quality of the product itself is not good enough, it will not pass the environmental test in the next process, so the product will not pass.

Moreover, benchtop temperature humidity cabinet is also applied in wireless communication, Industrial computer, cloud products, industries, different testing requirments are carried out by simulating the natural and accelerated environment, benchtop temperature and humidity chamber is a common equipment for environmental reliability testing.

What is the refrigeration principle of benchtop temperature humidity cabinet ?

The refrigeration circulation adopts reverse Carnot cycle, it includes two isothermal processes and two adiabatic processes: the refrigerant is compressed to high pressure through adiabatic compression of compressor, and then the refrigerant conduct heat exchange with ambient medium and transfer heat to these mediums isothermally. After then, refrigerant works by adiabatic expansion through cut-off valve, and the temperature of refrigerant decline. Finally, refrigerant absorbs heat from objects of high temperature isothermally through evaporator to reduce the temperature of the objects to be cooled. This cycle shall repeat to realize temperature decrease.
