“…Table 4 shows that joints C3 and C4 reached process temperatures of 331 ºC and 341 ºC, respectively, which are lower than those of C1 owing to the lower RS and FF values used. However, the observed temperatures are higher than those in C2, which suggests that a higher DaF (4 mm) increased the contact area, thus increasing the heat generation, as also observed by De Proença et al [11]. C3 and C4 exhibited similar joint rivet penetration and deformation, primarily at the PCB surface.…”

The Friction Riveting process has shown promising feasibility for a variety of material combinations and applications in the transportation industry. Recent research has explored the potential application of this technique in electronics, specifically for the assembly of printed circuit boards (PCBs), using AA-2024-T3 rivets on thin glass-fiber-reinforced epoxy substrates. Considering these promising results, this study focuses on the effects of reducing the diameter of the rivets used in Friction Riveting because of the need for downscaling when joining assemblies on a smaller scale. Therefore, the joint formation of joints produced with PCBs was investigated in terms of process temperature evolution, microstructural changes, and mechanical properties. Joints were obtained at process temperatures ranging from 285 ºC to 368 ºC. Notably, the use of 4 mm rivets resulted in extensive delamination, weak joint mechanisms, and cracking. These issues were impaired by the different coefficients of thermal expansion of the materials involved. However, reducing the rivet diameter to 3 mm significantly improved the joint quality. Although a further reduction to 2.5 mm rivet diameter minimized delamination, it led to insufficient anchorage and cracking. Overall, joints produced with a 3 mm rivet diameter achieved the highest ultimate tensile force (UTF) of 276 N. This study lays the foundation for applying the Friction Riveting process to practical PCB assemblies. It demonstrates that it is possible to achieve a balance between sufficient rivet anchoring, minimized delamination, and reduced cracking by optimizing the process parameters to the diameter-to-thickness ratio. Further joint optimization can be deduced from this study by potentially using rivets with lower plasticizing temperatures and selecting PCBs with improved heat resistance. In summary, this research highlights the prospect of Friction Riveting as an innovative method for PCB assembly, demonstrating the critical role of temperature control and rivet diameter in ensuring robust joint formation and performance.

This paper presents experimental investigations on the solid-state joint of 3 mm sheets of AlMg3 alloy with X2CrNiMo17-12-2 stainless steel. The study presents a dissimilar joint that was made in a solid state using a modified milling cutter. The study highlights the possibility of using this type of joint in a naval field. The paper presents all the steps of the joining process, from the technological parameters to the examination and numerical validation of the obtained specimens. A numerical model was defined in Abaqus, considering a Static analysis, and the results demonstrated a good similarity with a small discrepancy observed in the elastic range of the specimen behaviour. In the conclusions, this study will provide some recommendations for the optimisation of this joint and proposals for future studies; the idea for this study started from the dissimilar joints used in the naval field. The article also briefly presents some dissimilar joints made on the same milling machine and in the same laboratory.

Hybrid joints of short glass fiber‐reinforced polyamide 6 and 6056‐T6 aluminum alloy (PA6‐30GF/AA6056‐T6) are produced by friction riveting under different processing conditions. A comprehensive study of the effects of the processing parameters on the temperature evolution, anchoring efficiency, degradation of the polymer composite, and tensile strength (pullout test) of the joints is performed. With higher values for the rotational speed, spindle displacement, and joining force, the heat input is increased and this results in greater deformation of the rivet tip and thus higher anchoring efficiency. Based on this finding, high‐strength joints with tensile strength (pullout test) of up to 93% of the metal rivet are obtained and failure occurred through the ductile fracture of the metal rivet outside the composite plate region. Process‐related degradation of the polymer composite is identified, with the formation of voids in the polymer thermo‐mechanically affected zone (PTMAZ) as well as PA6 chain scission and glass fiber breakage in the rubbing volume around the rivet. The recrystallization of the PA6 matrix in the PTMAZ is not affected by the processing. Degradation of the composite at the polymer‐metal interface does not reduce the quasi‐static tensile strength (pullout test), although it may affect the long‐term mechanical properties of the joint.
