Process for coating at least one surface of a polyimide sheet with copper |
摘要 |
At least one surface of a polyimide sheet surface is coated with copper in the absence of an adhesive. The polyimide surface is treated with a one phase aqueous solution comprising an alkylene diamine; an alkali metal hydroxide and a water miscible alcohol to render the surface uniformly and substantially completely textured. The treated surface then is treated with a catalyst, coated with cobalt or nickel and then coated with copper. The laminate produced passes the IPC tests for peel strength and solder float.
