Thermal Shock Device TSA Series

Thermal Shock Device TSA Series

A thermal shock device with stationary samples that switches between low and high temperatures in the same chamber using a damper.

- Complies with standard tests such as IEC60068-2-14Na and MIL-883L. - Two-zone and three-zone methods through damper switching. - There is no vibration stress on the sample due to movement, ensuring more accurate test results. - 1000 cycles of continuous operation. Defrost-free function (optional). - Continuous cycle testing for 500 hours is possible without interruption due to defrosting during the test. Continuous operation for 500 hours can be achieved without interruptions for defrosting. Under the 15-minute exposure test conditions, continuous testing for 1000 cycles can be performed without interruption, reducing defrost time and defrost power during the cycle test. - Achieves both power consumption reduction and shortening of test time simultaneously.

Highly Accelerated Life Testing Device (HALT)

Highly Accelerated Life Testing Device (HALT)

Detect product weaknesses in a short period during the initial stage of the productization process, which is development/design! "Towards shortening product development lead time and further improving reliability."

This is a testing tool designed to quickly detect product weaknesses and eliminate potential defects in the manufacturing process during product development. By repeatedly detecting and improving weaknesses and adding evaluations, the reliability of the product is further enhanced. 【Features】 ■ Wide temperature range: -100℃ to +250℃ ■ Rapid temperature change: 60℃/min or more ■ Random vibration with 6 degrees of freedom due to repeated shocks 【Main effects expected from HALT testing】 ■ Improved product robustness By applying "strong stress" (rapid temperature changes and 6 degrees of freedom vibrations) that exceeds product specifications, design weaknesses are made apparent. Improving the failure points enhances the robustness of the product. ■ Shortened development cycle By discovering and improving potential defects during the development phase, risks and rework that occur in later processes are reduced. Reliability comparisons during changes in parts or with existing models can also be confirmed in a short period through testing under "strong stress." As a result, the development cycle can be shortened further. ■ Reduction of warranty costs, etc. By addressing latent defects that are difficult to detect with conventional testing, troubles after market release can be prevented, thereby reducing total costs, including warranty expenses associated with the product.
