Highly Accelerated Thermal Shock Testing

Highly accelerated thermal shock testing evaluates the robustness of PCB and substrate interconnections through rapid, repeated temperature changes. It is particularly useful for investigating via structures and plated through-holes that may be stressed during assembly and subsequent operation.

Thermal cycling places repeated strain on interfaces between materials with different expansion behavior. Suitable test systems can monitor resistance during the exposure to detect changes in interconnection integrity. Coupon design, measurement connections and the chosen profile are central to obtaining useful evidence.

Before selecting equipment, define the structures to be evaluated and the thermal conditions they must experience. Consider sample capacity, monitoring channels and the required transition and dwell behavior. Comparing materials or process changes requires consistent sample preparation and a clear failure criterion. Results should be related to the specific test structure and procedure.
