Galden® PFPE Thermal Shock Testing
Thermal Shock: The Test
Thermal shock testing is conducted to assess the resistance of electronic equipment to extreme temperature variations. The test involves alternately immersing the device into two liquid baths maintained at different temperatures. For military applications, thermal shock testing must comply with the requirements outlined in MIL-STD-883 Method 1011 or MIL-STD-202 Method 107.Dual-Fluid or Single-Fluid?
Dual-Fluid System
Traditionally, two different fluids can be used in the hot and cold baths. However, this approach presents several disadvantages:
- High fluid loss in the cold bath
- Cross-contamination between hot and cold fluids
- Equipment downtime
- Need for two separate fluid inventories
Single-Fluid System
Galden® PFPE fluids and their use in single-fluid systems offer a beneficial alternative to dual-fluid solutions.Galden® D02TS and D03 are single fluids that can effectively replace dual-fluid systems.
- Galden® D02TS is recommended for all military applications; it complies with MIL-STD-883 and MIL-STD-202.
- Galden® D03 is suitable for all non-military applications.
Using the same fluid in both baths significantly reduces operational costs by:
• Lowering fluid consumption
• Reducing equipment downtime
• Eliminating cross-contamination
• Simplifying inventory management with a single product
