WERKWIJZE TER VERVAARDIGING VAN EEN KOPERFOELIE, ALSMEDE EEN LAMINAAT, DAT VAN EEN DERGELIJKE KOPERFOELIE IS VOORZIEN.

摘要

Copper foil is subjected to a plurality of copper layer treatments including a roughening treatment followed by a locking or gilding treatment so as to form a matte surface on the copper foil. The matte surface is then coated with a thin layer of zinc and heated to produce a brass layer which provides the copper foil with good bond strength with respect to a supporting substrate, and without laminate staining or discoloration. Other metals may also be used in lieu of zinc.
