Impurity be deposited directly on lower guide roll, there are following several copper foil quality problems after lower guide roll in copper foil：(1) part is small
The impurity plating absorption of particle produces copper foil burr in copper foil surface.(2) the big impurity of particle causes copper under the extruding of pressure roller
Paper tinsel perforation produces copper foil load mould.(3) impurity of larger particles can make copper foil smooth surface have scratch scratch.Above quality problems cause copper
Paper tinsel is largely scrapped.Scrapped in place if not checked during jagged, load mould copper foil cutting, these copper foils are used to prepare wiring board,
The conductive open circuit of wiring board can be caused after pressing plate, so as to cause wiring board to be scrapped.The method for solving impurity deposition problems at present is general
It is that, by going manual cleaning to electrolytic bath bottom under plant operations personnel, because impurity is deposited on lower guide roll and bottom land, cleaning is needed
Shut down 2-3 hours, had a strong impact on the production efficiency of copper foil.
