• Thermal Shock Cycle Parameters
  • The chamber can be programmed to perform a highly customizable number of thermal shock cycles, ranging from a few dozen to several thousand, depending on the specific military component's requirements and expected service life. The dwell time in each temperature zone can be adjusted from milliseconds to hours, enabling the simulation of a vast array of mission profiles. For instance, a sensor used in a surveillance drone may need to withstand short, intense thermal shock cycles during rapid altitude changes, while a communication chip in a military base station might experience longer, more gradual temperature changes over an extended period.
• Testing Volume and Payload Capacity
  • The chamber offers a flexible testing volume, usually ranging from 1 m³ to 5 m³, to accommodate a significant number of microelectronic components. The payload capacity is designed to handle small but highly valuable and sensitive items, with a maximum capacity of up to several kilograms. This allows for the testing of individual components or small batches of components in a controlled and precise environment.
• Data Sampling Frequency and Resolution
  • The data acquisition system samples data at a high frequency of up to 1200 Hz. The temperature data has a resolution of 0.05°C, providing an unprecedented level of detail in monitoring temperature changes. This high-resolution and frequent sampling enable the detection of even the most minute temperature fluctuations and trends, allowing for a comprehensive understanding of the component's behavior during thermal shock testing and facilitating the identification of potential failure modes.
