Pressure Paper Testing: Process Verification, PSA Activation, and Operator Training

Pressure paper testing is a non-destructive method to evaluate contact pressure distribution between mating surfaces in precision manufacturing. This paper presents a detailed methodology including pressure-sensitive adhesive (PSA) activation, manual process verification, and structured operator training to ensure consistent, repeatable, and validated results. The study includes detailed tables, procedural steps, and example data illustrating pressure distribution assessment and operator qualification, providing a practical framework for process validation in medical device, electronics, and automotive manufacturing.
