Note: The data are ud only for calculating out the required heater capacity and exhaust volume and have no relation with actual production speed nor product quality.
5)Coating quality and accuracy:
5.1The outboad edges of coating shall be of the same thickness as in the center part so that no ridges will develop on the rewind roll.
5.2Thickness consistency: ≤±2µm for single side and ≤±4µm double sided.
5.3The coating length and width: the coating length and width both for 1st and 2nd sides are measured parately by ruler to meet the tolerance range: <±1mm.
5.4First-to-cond side registration at the initiation and termination ≤±1mm.
5.5First-to-cond side alignment at outboard edges (Left and Right) ≤±1mm.
5.6Squareness of coating: The maximum distance between initiation or termination and the line (perpendicular to the foil edge) to be ≤±1mm.
5.7See attached drawing
