HAST Chamber – Highly Accelerated Stress Test Chamber

● HAST Chamber, Accelerated testing is an approach for obtaining more information from a given test time than would normally be possible. It does this by using a test environment that is more severe than that experienced during normal equipment use. Highly Accelerated Stress Testing (HAST) is one method of accelerated testing. HAST chamber has gained in popularity as it can deliver results in typically 100 test hours.

● Highly Accelerated Stress Testing (HAST) was developed by Nihal Sinnadurai while working as a Research Engineer at British Telecommunications Research Laboratories in 1968 in order to perform highly accelerated reliability testing of electronics components that are likely to encounter humid environments during normal (ambient) operation. The test is sometimes referred to as the Pressure Cooker Test (PCT).

● Temperature Humidity Bias (THB) is a similar humidity and temperature testing process. THB is used to accelerate corrosion activities in metal and typically requires a test time of 1000 hours. Test samples at room temperature are placed in the hast chamber, any electrical connections being made. Humidifying water is also added. After the chamber has reached 100C air from within the chamber is released so that the atmosphere remaining in the chamber is water vapour.

HAST Chamber
1 Inner Dimension: 450×300 mm(φ×D) Testing Room Space
2 External Dimension: 1050×950×1550 mm(W×D×H)
3 Inner Material: SUS304# Stainless Steel Material
4 Body Material: SUS304# Stainless Steel Material
5 Temperature Range: 105℃ ~ 132℃can be set freely.
6 Humidity Range: 60%~100%RH saturated steam humidity can be set freely
7 Pressure Range: 0.5Kg/cm~2.00Kg/cm2
8 Safety Pressure Capacity: 2Kg/cm2 / G = 1ambient atmosphere pressure
9 Time Range: 0 ~ 9999 Hours
10 Temperature Difference: (+/-) 1.0℃
11 Heating Time: RT ~ 132℃within 65 min
12 Pressure Time: 0.0Kg/cm2 ~ 1.00Kg/cm2 about 35 min

● The vapour pressure inside the hast chamber is then raised to the test value where it is maintained for the designed test time. Test item functionality tests and parameter measurements can be performed within the test environment. At the end of the vapour pressure test the hast chamber and test item are cooled or allowed to cool naturally. Final examination and test of the item should be performed within twenty fours hours of cooling.

● Testing will only inform on the performance of products subjected to test parameters. When these results are used in a model to extrapolate performance at different levels of stimulus (moisture and pressure) or time interval the results will only be as good as the model employed. As with all models, They are only a model and not reality itself and therefore the limitations of the model must be understood if the modelling results are to usefully contribute to a product design or development.

● Within the discipline of Reliability, HAST Chambers can be used to reduce the time required to complete humidity and temperature testing of semiconductor and other electronic devices. Critical Assumption – The same failure mechanisms will be present at the higher stress levels and will act in the same manner as at normal stress levels.

Testing Standard IEC 60749 : Semiconductor devices Mechanical climatic test methods. 5C Damp heat, steady state highly accelerated.

● Unless fully protected – Hermetically Sealed, semiconductor devices and other components will be subjected to the effects of moisture in the air, Humidity. The use of desiccants and other moisture extraction systems can reduce the humidity that the devices are subjected to.

● Relative humidity is the term used to describe the amount of moisture in the air relative to the maximum amount of moisture that the air can hold at a given temperature and pressure. Therefore for a relative humidity of 50% the moisture in the air is half the amount of moisture that the air could hold. The chart below illustrates relative humidity for 100% and 50%. From the chart it can be seen that the amount of moisture that air can hold rises rapidly with temperature.

● The relative humidity (φ ) of an air water mixture is defined as the ratio of the partial pressure of water vapour (H2O) (ew) in the mixture to the saturated vapour pressure of water (e*w) at a prescribed temperature. Relative humidity is normally expressed as a percentage and is calculated by using the following equation:

HAST Chamber

● The processes used in HAST chambers are intended to accelerate moisture penetration into the internal parts of the item under test by raising the water vapour pressure using a test chamber. The level of penetration and the effects are then evaluated to determine the test item’s resistance to humidity. The use of vapour circulation fans, vapour heaters and condensation shields will improve test reproducibility. As condensation will form on the walls and ceiling of the chamber if a shield is not provide it can drip onto the test item affecting the test results.

● Simplistically, the HAST chamber is a pressure vessel able to withstand the planned temperatures and pressures required for the test. The chamber contains water and a heater in order to produce the required humidity and gauges to measure the conditions within the chamber. More complex test systems consist of two chambers that allows for the creation of saturated or unsaturated levels of humidity.

Keystroke Life Tester

Keystroke life testers are devices used to determine the durability and reliability of computer keyboards. They simulate the repeated keystrokes that a keyboard would experience during normal use and measure the impact of these keystrokes on the keyboard’s performance. In this article, we will provide an overview of keystroke life testers, how they work, and their importance in the manufacturing industry.

Keystroke life testers use a mechanical arm to simulate keystrokes on a keyboard. They can be programmed to apply pressure and force on specific keys, allowing manufacturers to test the durability and performance of different areas of the keyboard. The mechanical arm hits the keys repeatedly, mimicking the repeated use that a keyboard would undergo during normal use. The total number of keystrokes, also known as the keyboard’s endurance, is monitored and recorded to measure the keyboard’s lifespan.

Keystroke Life Test Equipment, The three axis (XYZ) servo-control automatic key loading-curve tester which we simply named keystroke life tester used for various of tensile pressure test. It can set the coordinates, the machine automatically displacement test, and record the test value. Use the Windows Chinese Windows menu. All data can be stored (test conditions, load – stroke curve, life curve, inspection reports, etc.)

Keystroke Life Tester

The application for keystroke lift tester : 1, General product multi-point strength test automatically. 2, Key (keyboard) curve test (multi-point automatic displacement). 3, LCD resistance to stress testing (multi-point automatic displacement). 4, Pressure life test (multi-point automatic displacement). For more details check, Please send us a mail. I am waiting for you there ! Thank you.

Keystroke life testers play a crucial role in ensuring the quality and reliability of computer keyboards. By simulating the repeated keystrokes of normal use, these devices can identify potential defects and help manufacturers ensure that their products meet user expectations. As technology advances, we can expect keystroke life system to become even more sophisticated, further improving the durability and reliability of computer keyboards.

The importance of keystroke life testers lies in their ability to identify keyboard defects before they reach the market. Defective keyboards can cause frustration for users, and can also lead to expensive returns and repairs for manufacturers. By testing the durability and reliability of keyboards before they are released, manufacturers can ensure that their products are of high quality and meet user expectations.

Keystroke Life Tester
Test Load Range: 0 ~ 100N
Minimum Display Load: 0.01 mm
Z-axis Tests the Height and Stroke: Height 450mm;Moving 150mm
Z-axis Display Distance : 0.01、0.001mm (Option)

One of the most important aspects of keystroke life testing is the measurement of keystroke force. Different keys on the keyboard require different levels of force to be pressed. Keystroke life testers can be programmed to measure the amount of force required for each key and record it for later analysis. This data can be crucial in identifying potential defects in the keyboard, such as keys that are too difficult or too easy to press, or keys that get stuck.

In addition to measuring the endurance and force required for keystrokes, some keystroke life test machine can also measure other factors such as the speed at which the keys are pressed and released, the frequency of keystrokes, and the duration of keystrokes. This data can provide valuable insights into how users interact with keyboards and can help manufacturers make data-driven decisions about product design and development.

Features for the three axis (XYZ) servo-control automatic key loading-curve tester :
Can be arbitrary input X, Y axis coordinates, the machine automatically moves the position test.
Can enter the maximum test stroke and load, the computer automatically controls and tests.

Wewon Xenon Test Chamber’s Technical Questions and Answers

Wewon xenon test chambers are high-quality, reliable, and efficient pieces of testing equipment that are suitable for various applications across different industries. They come equipped with a powerful xenon lamp that can produce a spectrum of light that is similar to that of natural sunlight. The chambers come with advanced control systems that enable easy programming and monitoring of test cycles, as well as data logging and analysis.

Wewon xenon test chambers are a popular choice for conducting accelerated weathering and material degradation studies. In fact, They are the specialized environmental testing chamber used to simulate the effect of sunlight and weather on products. As with any complex piece of laboratory equipment, there may be technical questions and concerns that arise during use. Below are some common questions and answers about Wewon xenon test chambers:

Q1. How is the radiometer calibrated for Wewon Xenon Test Chamber ?
A: We have 2 ways to do the rediometer calibrate. Way 1 is, We have a measurement tool which can calculate the data automatically; Way 2 is, We have 1 unit standard parts and stock here, When we need the rediometer calibrate, We use this standard unit for calibration.
Q2. Is the radiometer single band such as 340nm or over the range 300-400 nm ?
A: Normally the Xenon lamp’s spectrum is 280–800 nm, If there has a special requet, We can filter out a part of band/ waveband. In Wewon, We have some manners to estimate the 280–800nm lamp’s strength. For example, Choose the UVA340 to do the estimation, or we can choose 300–400 nm band to estimate the lamp’s strength, But frankly to say, they have a same essence.
Q3. I assume there is a radiometer in Wewon xenon test chamber which measures the radiation intensity and user can adjust the radiation energy through that. My question is that how does this work ? Does it measure single band or measure the full spectrum 300-400 nm ? Besides is it portable or is it built-in in the chamber? can we move it in the chamber space to see whether the radiation is uniform ?
A: Principle: There is a measuring probe in Wewon’s xenon test chamber, The measuring probe do measurement for xenon lamps during it working. And transfer the testing data to the controller. The controller according with the setting value, and calculate controlled variable based on PID algorithm, and send to control device, In this way to control the Xenon Lamp’s output power.
The measuring probe will measurement the fully waveband, It fix inside the Wewon’s xenon test chamber and without move. If you want test the uniform of radiation, We can equip 2 or 3 pcs measuring probe inside, Then it works !
Q4. In Wewon xenon test chamber’s software manual I could not see the choice for exposure time and spraying time cycles and number of cycles. How can we do that ?
A: There has a procedure in Wewon xenon test chambers, So you can setting the exposure time, sprayting time, and cycles by yourself freely. We will make a short movie and teach you how to process the programme for exposure time, spray ting time, and cycles. It’s easier way to our both parties !
Q5. I need extra lamps and accessories since our lab is going to use the chamber non-stop.
A: OK, No problem, We can supply you continuously. Because we are the manufacurer, and sometimes we have the stock there.
Q6. How BST and BPT are selected ?
A: The Wewon xenon test chamber support both BST and BPT mode. BST normally used for testing the inner quality of samples, and BPT mainly doing the sample’s surface testing.
Q7. What is the radiation energy in kW/m2 for 300-400 nm range ? What is the maximum radiation energy for 300-400 nm ?
A: The intensity of the radiation depends primarily on the how many xenon lamps used and the power of lamps, The normally range is 60–110W/m2; But we can choose a 180W/m2 as well. We need apply the more strongly xenon lamps and more quantity xenon lamps to make it to be 180W/m2.
Q8. Can we remove filters to receive 300-800 nm energy band ?
A: It’s not means remove the filters, the inner/ outer filter, Try to choose borosilicate and we can get a 300-800 nm energy. In another words, The Wewon’s xenon test chamber can make it to 300-800 nm energy band.
Q9. Is that possible to use a higher power lamp such as 7.5kW or 12 kW to achieve higher radiation energy as possible ?
A: For this moment, The Wewon’s xenon lamp has a 6.5KW, and can get a MAX power which support 7.5KW, For the 12KW, We have not developed this type, Now we are working and developing for it.
Q10. Is the refrigeration system necessary? Let’s say we use the chamber 40-80 degree C.
A: Refrigeration system is necessary, Because the xenon lamps has quantity of heat, If we don’t use the refrigeration system, the fully xenon test chamber and parts will be limited, Because of heat, It’s not a smart idea for customer to reduce the refrigeration system
Q11. According to the data provided for the 60s time step for recording, the recording time will be 60 days, But somewhere you have mentioned the maximum recording time is 180 days. I need recording time up to 180 days and if it is no considered I suggest to delete 1 sec time step for recording and add 240 sec.
A: This is no problem for Wewon’s xenon test chamber. The customer better declare their request clearly during order, And we can meet this requirement.
Q12. Is it possible to put two 6.5 Kw lamps in the chamber ?
A: For sure, If we can equip 2 pcs 6.5KW, We will mentioned it in our data sheet. In fact, Even the ATLAS, Q-LAB, SUGA, still can not equip 2 pcs xenon lamp in a same chamber ! If you want a good and exactingly/ exactly radiation intensity, Better choose the ATLAS xenon test chamber or Wewon’s Xenon Test Chamber can meet your requirement.
Meanwhile, The Chinese supplier they equip 2 pcs even 3 pcs xenon lamps in the xenon test chamber with an air cooling way, They are doing a poor car way, In this solution they can not get an exactingly/ exactly radiation intensity. In fact, They are doing a false work without exactly testing data, The main problem is the poor solution what they have choosed.

What’s the purpsoe of a xenon test chamber ? A xenon test chamber is used to simulate the effects of sunlight, temperature, and moisture on materials and products. It is especially useful for testing the durability of materials that are exposed to outdoor conditions, such as plastics, coatings, and textiles. The chamber exposes the test specimens to xenon light, which simulates the UV spectrum of sunlight, and cycles the temperature and humidity to simulate different weather conditions.

By subjecting the materials to these conditions over a period of time, the xenon test chamber can determine how well they will hold up in real-world applications. This information is important for manufacturers, as it can help them improve their products and ensure that they meet industry standards and customer expectations. This allows engineers and researchers to evaluate the durability, performance, and reliability of products and materials in a controlled, accelerated manner, and make informed decisions about their design and manufacturing processes.

THE UL Certification for Magnetic Contactor used in Wewon’s Environmetnal Chambers

Wewon UL Certification, Most of the parts which used for environmental chambers, We prefer choose a famous brand. For example : Schneider, Gavazzi, Omron, Danfoss, Sporlan, Emerson, Unitè Hermetique, Bitzer and so on. The magnetic contactor which used in Wewon environmental chambers has got a UL certification as well. Confirm the Wewon UL CERTIFICATION for magnetic contactors, Please click here, The related document which supplied by Wewon’s magnetic contactor supplier|

● Magnetic contactor is common used in automation industry for motor control application.It is function basically like “relay”. The power source into the coil of winding,it like the solenoid operation. It can delivery a big ampere to the loads and very long lasting and high durability.


● When the power is “on”, it energized the coil and make plunger move and the switch contact is change from normally open to closed position. It allowed the current move from input terminal to output terminal. Then if we connected to the 3 phase motor, it will running.

● A magnetic contactor is part of an electromagnetic-operated switch that starts and stops a large-load electric motor through a control circuit that connects contact devices to the magnetic motor starter coil. The magnetic contactor is usually paired with an overload relay in a magnetic starter to flick the switch when the motor load exceeds its capacity.

● A magnetic contactor may be present in a magnetic starter as either stationary or moving, together with a solenoid coil, pressure springs, an electromagnet that is kept in place, magnetic shading coils and a mobile armature.

● If the motor has not been started yet, the magnetic starter does not receive current. As soon as the start button is activated, the electromagnet is powered up. The switch then engages the contactor and directs the current to the motor. When the stop button is pressed, the circuit is broken, which removes the energy from the electromagnet and current to the motor.

● The electromagnet automatically disengages the contactor when the motor power fails. This is possible through the use of momentary switches to call the functions on and off. A magnetic contactor coupled with an electromagnet is similar to ordinary latching mechanisms such as a light switch, although the latter does not disengage when power to the motor fails.

Identify Product Flaws Through Temperature Test Chambers !

Temperature test chambers are known for subjecting a test specimen to different temperature test and humidity test conditions. They are being used in several industries for the purpose of meeting intensive testing requirements. The objective of such testing is basically to determine the after effects of the virtual environmental conditions on the tested specimen. Generally this testing is conducted by manufacturers before the shipment of the finished products for the conduct of other types of testing such as mechanical or package performance testing.

The sample is exposed to a full range of potentially harmful temperature and humidity levels to bring out the faulty areas in it. The faulty areas are then addressed to increase the durability and reliability of products. The environmental chambers where this testing is conducted are specifically designed to maintain tight controls over temperature and humidity. You are given the facility to change the rates as per your testing need.

You must be wondering what the need of this intensive testing is. Actually, there is a huge possibility that the final product has to encounter similar kinds of conditions during an extreme distribution cycle, for example, if they are stored in a warehouse for an extended period of time. Also, it is important for the manufacturers to trace all the product flaws before their product actually reaches the market.
