APPLICATION: It is used to get rid of unnecessary resin jack, reduce copper foil thickness, remove residual copper dust, nodule and etc after electro-plating of HDI.
FEATURES: The grinding surface is well-distributed, which will not block holes , either scratching orifice.The sand is not easy to peel off which achieves good performance of brushing surface.
