Laboratory Constant Programmable Environmental Rapid Change Temperature Cycling Chamber
Rapid change temperature testing is a type of thermal cycling tests developed to improve the failure repeatability of thermal shock tests.
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 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).
AMBIENT ROOM CONDITIONS
The ambient condition of the room where the chamber will live is very important to make it running. Test chambers create a lot of heat, and with test cycling up and down the temperature spectrum, the chambers themselves require good air circulation.
Some units require 18-36 inches (or more) of clearance in all directions to work properly and to provide reliable data. Even more critical, is test chambers should operate in rooms with an average ambient temperature of 23°C (70°F).
The constant ambient room temperature will ensure that your test requirements only fluctuate when you want them to change. When the space housing the test chamber changes often, the chamber must work harder to regulate its own temperature to the programmed setting.
