Copper rivet 5.5*4 (tube length)

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…
