Abstract
Printed circuit boards have circuit layers with one or more via filled holes with copper wraps and methods of manufacturing the same. An embodiment of the present invention provides a method to enhance the consistency of the wraparound plating of through-hole vias of printed circuit boards with (requiring) via filling to provide extra reliability to the printed circuit boards and enables the designers and/or manufacturers of printed circuit boards to design and manufacture boards with relatively fine features and/or tight geometries.
