A semiconductor device has a substrate and a first conductive layer formed over the substrate. A second conductive layer is formed over the first conductive layer. The first conductive layer can be copper, and the second conductive layer can be nickel. A thickness of the second conductive layer is greater than a thickness of the first conductive layer. A flux material is deposited over the second conductive layer by a printing process. An electrical component is disposed over the flux material, and the flux material is reflowed to make electrical connection between the electrical component and second conductive layer.

An encapsulant is deposited over the electrical component.
