Copper rivet 5.5*4 (tube length) is a micro hollow rivet, which can be regarded as a
Mini screw in the riveting field. With an outer diameter of 5.5 mm, a tube length of 4 mm, and a total length of 6.5 mm, it is made of highly conductive C2680 copper strip by cold heading, and the surface is tinned to have both anti-oxidation and solderability. Its cavity design allows wires or optical fibers to pass through the core, realizing electrical-signal integrated fixation, and is an alternative to
Micro Screws commonly found in micro sensors and wearable modules.
As a positioning element at the level of Precision screw, the wall thickness of the rivet body is only 0.25 mm, the coaxiality of the inner hole is ≤0.02 mm, and a single press riveting can form a permanent interference fit with the substrate, with a tensile strength of ≥250 N and a torque attenuation of <2%. The automatic feeding system can complete feeding-pressing-cutting within 0.6 s, meeting the high-speed SMT line beat.
In aerospace electrical equipment, this copper rivet is certified by ASTM F1684 and can be used as a lightweight option for
Aerospace Micro Screws: it weighs 0.04 g, but has passed 30 g vibration and −55 °C~+150 °C thermal cycle tests, providing reliable riveting with low thermal resistance and high conductivity for satellite power modules and drone avionics boxes, helping to reduce the weight of the entire machine by 20%.
