It delivers stable performance, high removal rate, and excellent surface quality, with surface roughness controlled at 0.03–0.05 μm. After lapping, it achieves excellent warp and TTV performance, together with a shallow surface damage layer. Particle size can be customized upon request.</span></span></p><p><br/></p>
