  • Publication number: 20090017309
    Abstract: The present invention is directed to non-lithographic patterning by laser (or similar-type energy beam) ablation, where the ablation system ultimately results in circuitry features that are relative free from debris induced over-plating defects (debris relating to the ablation process) and fully additive plating induced over-plating defects. Compositions of the invention include a circuit board precursor having an insulating substrate and a cover layer. The insulating substrate is made from a dielectric material and also a metal oxide activatable filler. The cover layer can be sacrificial or non-sacrificial and is used to remediate unwanted debris arising from the ablation process.
