Abstract：To address the issue of edge refinement of copper plated wires in flexible cathode electrochemical machining，the influence of additive particle size and dispersion on copper plating quality was studied. The grinding time of additive particles and the slurry stirring method were adjusted，and laser activation was combined with electroless copper plating processes to prepare conductive wires and their morphology was analyzed. The results demonstrated that grinding time significantly influenced the particle size，which stabilized at 1.445 （20 μm after 48 hours of grinding，with improved dispersibility and reduced agglomeration. After stirring for 5mi 二 nutes using a high-speed disperser，the particle area fraction in polyurethane decreased by 11.9% compared to traditional stirring.The refinement and uniformly dispersed additive particles improved the uniformityof laser activated catalytic centers.Under the optimal conditions （48 hours grinding and 5 minutes high-speed stirring），the copper plated wires exhibited sharp and wel-defined edges，uniform distribution，and aconsistent wire width of approximately 85.1μm
