Customer Reviews
Thanks a lot for the professional service of Q1-Test team, we are happy to have the temperature test chamber, and it works well until now.

—— Tonny Cruise

Salt spray test chamber was installed last week according to your guide, it is working well now, thank you. we will recommend it to my friends.

—— Robert Antonio

Our 1000L temperature test chamber QTH-1000C works very well after installed and set by Q1-test service guy. Our staff can operate it fluently. Thanks

Lab Alternative High and Low Cycling Temperature Climatic Test Chamber with Microprocessor

 

Choosing Chamber Size:

Choosing a correct chamber size depends on the application and your available floor space. The suggested ratio is about 1:3 between product volume and the working volume of the chamber.

 

⅓ product to ⅔ empty space around the product ensures adequate airflow to the test sample and makes sure your test is conducted properly. Items that allow for airflow (such as a computer chassis with plenty of air vents) can take up a larger percentage of the test volume.

 

Externally, consider that these machines create a lot of heat, and with test cycling up and down the temperature spectrum, the chambers themselves require good air circulation. Some units will require up to three feet (or more) of clearance in all directions to work properly.

 

Depending on whether the test product is a live load, a larger chamber may be needed to dissipate heat produced by the test subject, adversely affecting the chamber’s pull down times or humidity system.

 

Sand, dust, and high altitude chambers do not need a 1:3 ratio of product volume and empty space. The air speed inside the chamber is already very high for the products and makes a 1:3 ratio unnecessary.

These chambers should be just slightly bigger than your test product.

 

Brief Introduction:

Rapid change temperature testing specifies a test sample temperature variation rate of 15°C/minute or less, which is the biggest difference between this method and thermal shock testing. Since rapid change temperature testing achieves highly repeatable test results, it is used for compliance testing for standards such as JEDEC (JESD 22-A104B).

 

With the ongoing rise in issues affecting the reliability of electronic devices and circuit boards, a better-suited evaluation testing method is needed to respond to issues such as higher device operation temperatures resulting from greater semiconductor integration, changes in device mounting methods such as BGA and CSP, and the use of lead-free solder.

 

Rapid change temperature testing is a type of thermal cycling tests developed to improve the failure repeatability of thermal shock tests.
