The dual-zone thermal shock chamber also complies with testing standards including IEC 61587-1, IEC 60601-1, IEC 60335-1, and IEC 60721.
Typical Application Industries
Structure and Working Flow
The two zone thermal shock test chamber designed to subject a Device Under Test (DUT) to severe thermal stress by rapidly transferring it between two independently controlled, extreme temperature zones (one hot, one cold) in an extremely short time.
- The Essence: The test evaluates the product's ability to withstand instantaneous changes in temperature.
- Physical Mechanism: When a product is rapidly moved from, for example, a high-temperature zone to a low-temperature zone, the different materials and components within it contract or expand at varying rates due to their unique Coefficients of Thermal Expansion (CTE). This discrepancy generates massive internal stress and shear forces at interfaces, solder joints, and material connections.
- Test Objective: To quickly expose latent defects arising from design, material selection, or manufacturing processes, such as:
- Solder joint fatigue and cracking
- Material delamination (layer separation)
- Component package cracking
- Structural or sealing failures
1
Hot Zone (Pre-heat Chamber)
The independent zone employs high-power heaters to maintain and stabilize the air temperature at the set maximum value (e.g., +150°C or +200°C).
2
Cold Zone (Pre-cool Chamber)
An independent zone that uses a Cascade Refrigeration System to maintain and stabilize the air temperature at the set minimum temperature. (e.g., −55 °C or −65 °C)
3
Specimen Carrier
Holds the DUT and is moved between the two zones by a dedicated transmission mechanism (pneumatic).
4
Quick Transfer Mechanism
Ensures the basket moves between the two extreme temperature zones for meeting the "shock" requirement.
5
Programmable Controller
Manages the entire test cycle, allowing users to set temperature limits, Soak Time (exposure duration), and the total number of cycles, while logging test data.
