      pad size is .45mm X .45mm, pitch is 0.8X0.8mm, Minimum clearance is 0.2mm in this spec if we use above 18Mil annular ring and 8mil hole , getting clearance error wit adjacent pads

        You stated that minimum Clearance between the pads is 0.2mm. Is this information given in the datasheet?
        Could you please share the Part Number?
