A controlled oxygen content copper clad laminate product and process. In accordance with one aspect of the present invention, there is provided a laminate having a first layer of oxygen-free copper joined to a second layer of oxygen-rich copper by the steps of (i) cladding the first layer to the second layer at a relatively low speed to minimize rolling friction, (ii) finish rolling the laminate to substantially increase its thickness tolerance, (iii) slitting the laminate to increase its width tolerance, (iv) profiling a groove at a selected location in the laminate, (v) finish slitting a plurality of ribbons from the laminate, (vi) tension leveling the laminate to straighten and flatten its shape, (vii) stamping the laminate into sections each of a selected configuration, (viii) cleaning laminate surfaces, and (ix) direct bonding the laminate to a substrate material such that the first layer is annealed to the second.
