The roll-to-roll (R2R) lamination process is a promising technology for the fabrication of flexible electronic devices on large areas such as solar cells or organic light emitting diodes. In this study, mechanical factors in the R2R lamination process that affect the adhesion strength of laminated composite were studied by finite-element simulation based on a theoretical model. Moreover, the effect of mechanical factors on the attenuation of adhesion strength was evaluated by using a full factorial design of experiment. The results show that the adhesive strength of the laminated composite decreases as the operating tension and strain rate increase. However, the radius of the roller has the opposite tendency to the operating tension. Non-linear regression model was developed to express the adhesion strength according to the mechanical factors, followed by the determination of their ranges to minimize peel-off. The suggested analysis method, devices and non-linear regression model could be used as a guideline to pre-determine the operating conditions in the R2R lamination process before manufacturing laminated composites.
