note = {The growing demand for smaller, more efficient electronic devices is
driving the need for innovative PCB joining techniques. Traditional
methods are limited in terms of mechanical reliability and thermal
stress. Friction riveting (FricRiveting) is emerging as a promising
solderfree alternative. This research project investigates the
feasibility of using FricRiveting for PCB assembly, with a focus on
optimizing process parameters and understanding joint performance.
Joints were produced using AA-2024-T351 rivets and FR4 laminate.
Various experimental techniques were employed to characterize the
joints, including optical microscopy, infrared thermography,
mechanical testing and advanced thermal analyses such as differential
scanning calorimetry (DSC) and thermogravimetric analysis (TGA). The
findings show that rivets can be effectively anchored within the FR4,
provided the process temperature is kept below 360°C. However,
excessive heat causes the epoxy resin to degrade, which has a negative
impact on the long-term integrity and reliability of the joint. The
study highlights rotational speed and friction force as crucial
parameters for joint quality. In conclusion, FricRiveting shows great
promise for PCB applications, offering a sustainable and robust
joining method. However, further optimization is essential to mitigate
the effects of thermal degradation and integrate the process into
high-volume automated manufacturing lines.},
