Abstract:
A method for forming a circuit pattern on a substrate may include the steps of: providing a substrate having an insulating surface including a pattern-forming region; printing only on a portion of the insulating surface, including the pattern-forming region, with an activation ink so as to form an activation layer on the portion of the insulating surface; forming a first metal layer on the activation layer by electroless plating; and isolating a patterned portion of the first metal layer, which is formed on the pattern-forming region, from a remaining portion of the first metal layer.
Abstract:
A non-deleterious method for producing a continuous conductive circuit upon a non-conductive substrate can begin with the application of a metallic base layer upon a surface of a non-conductive substrate. A circuit pattern can be created within the metallic base layer based upon a circuit design. The metallic base layer comprising the circuit pattern can be physically separated from the remainder of the metallic base layer on the non-conductive substrate. The region of the non-conductive substrate surface that encloses the circuit pattern can be called the plating region. The remainder of the non-conductive substrate surface can be called the non-plating region. A first metal layer can be added upon the metallic base layer. A second metal layer can be added upon the first metal layer of the plating region. The second metal layer can be electrically conductive and restricted from forming on the first metal layer of the non-plating region.
Abstract:
A conformal array antenna includes a substrate and a conductive circuit. The substrate has a non-conductive roughened curved surface formed with a plurality of hook-shaped structures that are formed by blasting a plurality of particles on the substrate. The non-conductive roughened curved surface defines a plurality of spaced-apart antenna pattern regions. The conductive circuit is located in the antenna pattern regions, and includes an activation layer formed on the roughened curved surface and containing an active metal, and a first metal layer formed on the activation layer.

A method for making a conformal array antenna includes: providing a substrate having a non-conductive curved surface; roughening the curved surface; forming an activation layer containing an active metal on the roughened curved surface; forming a first metal layer on the activation layer by chemical plating process; and defining a plurality of spaced-apart antenna pattern regions on the first metal layer, by forming a gap along an outer periphery of each of the antenna pattern regions to isolate the antenna pattern regions from a remainder of the first metal layer. The curved surface is roughened by blasting a plurality of particles thereonto, or the spaced-apart antenna pattern regions are substantially evenly distributed.

A method for fabricating a conductive trace structure includes the steps: forming a first metal layer on a non-conductive substrate; removing a part of the first metal layer to expose the non-conductive substrate so as to form the first metal layer into a plating region and a non-plating region, the plating region being divided into at least two trace-forming portions and at least one bridge portion; forming a second metal layer on the plating region by electroplating the plating region using one of the trace-forming portions and the bridge portion as an electrode; and removing the bridge portion and the second metal layer formed on the bridge portion.
