Abstract
The invention relates to a method for the manufacture of an electrically conductive metallic strip for the production of plug contact elements. A starting strip of copper or a copper alloy having an initial thickness which is greater than its final thickness is tin-plated. Subsequently, the tin-plated copper strip is deformed by rolling. This rolling process reduces both the thickness of the layer of tin and the thickness of the underlying copper strip.
Claims5
A method for manufacturing an electrically conductive metallic strip for use in the production of plug contact elements in which a starting strip is made of copper or a copper alloy and has an initial thickness which is greater than its final thickness, comprising the steps of:
- subjecting the starting strip to a heat treatment at a temperature between 200° C. and 650° C.;
- coating the starting strip with a coating of tin or a tin alloy after the starting strip has been subjected to the heat treatment;
- subsequently rollingly deforming the coated starting strip so as to reduce its thickness to a production thickness;
- and
- heating said strip to an elevated temperature which is above room temperature and performing a heat treatment at said elevated temperature after the final production thickness is reached.
