  • Patent number: 11466379
    Abstract: A manufacturing method of copper foil and circuit board assembly for high frequency transmission are provided. Firstly, a raw copper foil having a predetermined surface is produced by an electrolyzing process. Subsequently, a roughened layer including a plurality of copper particles is formed on the predetermined surface by an arsenic-free electrolytic roughening treatment and an arsenic-free electrolytic surface protection treatment. Thereafter, a surface treatment layer is formed on the roughened layer, and the roughened layer is made of a material which includes at least one kind of non-copper metal elements and the concentration of the non-copper metal elements is smaller than 400 ppm. By controlling the concentration of the non-copper elements, the resistance of the copper foil can be reduced.

  • Patent number: 11316006
    Abstract: A porous region structure and a method of fabrication thereof are disclosed. The porous region structure is characterized by having a hard mask interface region with non-uniform pores sealed and thereby excluded functionally from the structure. The sealing of the hard mask interface region is done using a hard mask deposited on top of an anodization hard mask used to define the porous region of the structure. By excluding the hard mask interface region, the porosity ratio and the equivalent specific surface of the porous region structure can be controlled or quantified with higher accuracy. Corrosion due to exposure of an underlying metal layer of the structure is also significantly reduced by sealing the hard mask interface region.

  • Patent number: 9970080
    Abstract: Micro additions of certain elements such as zirconium or titanium are added to high strength aluminum alloys to counter discoloring effects of other micro-alloying elements when the high strength alloys are anodized. The other micro-alloying elements are added to increase the adhesion of an anodic film to the aluminum alloy substrate. However, these micro-alloying elements can also cause slight discoloration, such as a yellowing, of the anodic film. Such micro-alloying elements that can cause discoloration can include copper, manganese, iron and silver. The micro additions of additional elements, such as one or more of zirconium, tantalum, molybdenum, hafnium, tungsten, vanadium, niobium and tantalum, can dilute the discoloration of the micro-alloying elements. The resulting anodic films are substantially colorless.
