<p><span style="font-size: 16px; font-family: arial, helvetica, sans-serif;">SR-15 μm is designed for coarse lapping of silicon nitride ceramic substrates. It provides stable performance, high removal rate, and good surface quality, with surface roughness controlled at 0.2–0.5 μm. It effectively improves surface unevenness after ceramic substrate sintering, delivering excellent warp and TTV performance, as well as a shallow surface damage layer after lapping. Particle size can be customized upon request.</span></p><p><br/></p>
