From consumer electronics to electronic components for industrial applications to underhood components, thermal shock testing has become a life cycle durability testing requirement for many OEMs and end users. A thermal shock  chamber exposes parts to rapid cycling of hot and cold temperatures.  The breaking point in this process is called tensile strength.  The thermal shock process determines that breaking point and leads development engineers down a path of designing for greater robustness.

Various industry standards have been increasing the requirements for thermal shock due to a number of factors: 

  • Miniaturization of parts and equipment make them susceptible to heat 
  • Production processes such as reflow soldering inflict extreme heat
  • Demands for higher product precision cause greater heat stress during production
  • Far more electronic component use over mechanical, specifically in the automotive industry
  • Efforts within the automotive industry to make lighter yet stronger parts throughout the entire vehicle require the need to know how they will handle extreme temperature changes
  • Extreme/rapid temperature changes within engine compartments on components under the hood

Smithers' experts can work with your development team to understand the requirements for your product or material. They can then recommend standard test protocols or develop a custom testing program to ensure that you will receive the data needed to make critical product development decisions.
