The insertion and removal lifespan of a SIM card connector is primarily determined by the elasticity of the contact material and the thickness of the surface plating.
Standard consumer-grade SIM card connectors are typically designed for around 5,000 mating cycles,
while industrial-grade versions can exceed 10,000 cycles.
During mating cycle tests, when the gold plating thickness is below 0.3 μm,
contact surface wear accelerates significantly, leading to a noticeable increase in contact resistance.
To address this, MOARCONN adopts a thickened gold plating design in its high-durability models,
ensuring electrical performance remains stable and within industry-accepted limits even after
up to 10,000 insertion cycles.
