Debonding or pull-off: identify the cause and validate performance with adhesion tests

Debonding or pull-off highlights insufficient adhesion performance, with a direct impact on quality, scrap and returns.
The root cause may come from the surface condition, insufficient surface preparation, material variability or a process setting. Without measurement and testing, corrective actions often remain approximate.

STTS supports this phase with a fact-based approach: defect observation, selection of the most relevant adhesion test, then performance validation.
Depending on the case, STTS uses a cross-hatch test (for coatings) or a pull-off test (for bonding/assembly) to obtain clear, comparable results.

The goal is to move quickly from observation to an action plan: confirm the cause, validate a correction, and secure production restart.
