Abstract:
A method for manufacturing traces of a printed circuit board (PCB) comprises an application of the periodic pulse reverse (PPR) pattern plating process. In the first stage, walls and bottoms in drilled holes of the PCB are modified with reduced graphene oxide (rGO) so that the vias can be formed by filling with copper and a very thin copper layer can be formed on the substrate through the electroplating process. In the second stage, a pattern of very fine traces with width/space less than 30/30 μm is formed on the thin copper layer and then the traces are formed through the PPR pattern plating process. After removing unwanted copper layer, the traces with even thicknesses and square profiles are achieved and thus conform to requirements of the high density interconnection (HDI) technology.

Claim (Index 1):
A method for manufacturing traces of a PCB, comprising steps of:\n A. providing a substrate with a copper cladding layer and drilled holes and modifying walls and bottoms of the holes with reduced graphene oxide (rGO); B. filling the holes with copper and forming a thin flat copper layer over the copper cladding layer with a thickness of 1-20 \u03bcm at a variation of less than 10% through an electroplating process; C. forming a patterned anti-plating film on the thin flat copper layer to define an area of traces having widths of 3-50 \u03bcm and interval spaces of 3-50 \u03bcm; D. depositing copper on the area of traces with thicknesses of 5-50 \u03bcm at a variation of less than 15% through a periodic pulse reverse (PPR) plating process; E. removing the anti-plating film; and F. etching the thin flat copper layer and the copper cladding layer without copper deposited thereon.
