Bipedal Robot Joint Sensor FPC
This FPC is designed for bipedal robot joint sensor assemblies. To address component failure due to salt mist corrosion, Hongyi Precision developed an optimized zoned surface finish solution: ENIG applied to critical pads for oxidation resistance, durability under repeated mating cycles, and stable solder joints; tin plating used on non-critical trace areas to reduce overall production cost. This zoned approach balances long-term reliability and cost, successfully passing robotic environmental reliability testing.
