Energy Saving Climatic Temperature Cycling Environmental Test
Chamber by PID Controlled
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.
