Copper foil is a key conductive material for making printed circuit board, which can be divided into electrolytic copper foil and rolled copper foil according to different manufacturing process
(1) the Rolled Copper Foil is the original Foil (also called wool Foil) made from the repeated rollers of the Copper plate, and roughened it according to the requirements.
Due to the limitation of the copper foil processing technology, the width of the copper foil is difficult to meet the requirement of rigid copper plate, so the copper foil is used very rarely on the rigid coated foil.
Because the compressibility and elastic coefficient of the copper foil is greater than that of electrolyte copper foil, it is suitable for the flexible coating of copper foil.
&©|160;
(2) electrolytic copper foil (a) is to dissolve the copper before it is dissolved into a solution, and then, in a special electrolytic device, the copper sulfate electrolyte can be deposited into the original foil under the action of direct current.
Surface treatment, heat resistance layer treatment and oxidation treatment of the original foil are then required.
The electrolytic copper foil is different from the rolling copper foil, which is different from the two surfaces of the copper foil, and the side of the cathode roller is smooth, which is called the smooth surface.
The other side presents the structure of the crystallographic structure of concave convex shape, which is relatively rough, called the hairy surface.
There are some differences in the surface treatment of electrolytic copper foil and rolled copper foil.
Due to the structure of the structure of the column of electrolytic copper foil, the properties of strength and toughness are inferior to that of rolling copper foil, so the electrolytic copper foil is used for the production of rigid copperplate, which can then be made into a rigid printing plate. |
