    Abstract: A high temperature circuit board made by flame spraying a high temperature resistant metal film, such as aluminum, zinc or silver solder braze alloy, onto a high temperature resistant insulative substrate in which in one embodiment a reverse circuit image resist is layed on the board surface and the metal is flame sprayed onto the board surface and the reverse image resist screen is then removed leaving the circuit without etching. In the other embodiment aluminum is flame sprayed onto the substrate and then a silver solder braze alloy or copper or nickel is flame sprayed onto the aluminum film, and then resist and etching stops are applied to remove unwanted metal to the substrate and the resist is stripped providing the high temperature printed circuit board.

    Abstract: A printed circuit board for mounting integrated circuit and resistor network packages commonly referred to as flatpack components and a process for fabricating the circuit board. The printed circuit board has a conductive pattern of electrical connection pads for connecting to electrical leads from flatpack components and electrical conductors for connecting the pads to circuitry external to the board. A channel for receiving and aligning each electrical lead from a flatpack component is formed by printed circuit techniques. The surface layer of each channel is formed of solder which simplifies the process of electrically connecting flatpack leads and reduces errors occuring in the soldering process.

    Abstract: A wiring board includes: a substrate; a first seed layer provided on the substrate; a first conductive layer provided on the first seed layer; a first insulating layer provided on the first conductive layer; a second seed layer provided on the first insulating layer; and a second conductive layer provided on the second seed layer. An area of the first insulating layer is smaller than an area of the first conductive layer. An area of the second conductive layer is smaller than the area of the first insulating layer. A region of the first insulating layer not overlapping the second conductive layer includes a first region surrounding the second conductive layer and a second region outside the first region. A surface roughness of the second region is larger than a surface roughness of the first region.

    Abstract: A wiring substrate includes a first wiring layer, an insulation layer covering a side surface of the first wiring layer and exposing part of the first wiring layer, and a second wiring layer formed on the first wiring layer exposed from the insulation layer. The insulation layer includes a resin and a filler. The insulation layer includes an upper surface having a structure in which the filler is exposed from the resin. The second wiring layer includes a first metal film, covering the upper surface of the insulation layer and the wiring layer exposed from the insulation layer, and a metal layer, formed above the first metal film. The first metal film is formed from a CuNiTi alloy and has a Ni content rate of 5 wt % or greater and 30 wt % or less and a Ti content rate of 5 wt % or greater and 15 wt % or less.
