Abstract:
A manufacturing method for a component incorporated substrate according to the present invention includes positioning an electronic component with reference to a mark formed on a copper layer, the mark consisting of a material less easily etched than copper by a copper etching agent used for etching of copper, after mounting the electronic component on the copper layer with an adhesive layer interposed therebetween, embedding the electronic component and the mark in an insulating substrate, thereafter, etching and removing a part of the copper layer to form a window for exposing the mark, forming an LVH reaching a terminal of the electronic component with reference to the exposed mark, electrically connecting the terminal and the copper layer via a conduction via formed by applying copper plating to the LVH, and, thereafter, forming the copper layer into a wiring pattern.

A thermoplastic resin composition comprising: per (A) 100 parts by weight of a crystalline thermoplastic resin having a melting point, measured by differential scanning calorimetry (DSC) at a heating rate of 10° C./min, of 250° C. or above; (B) 10 to 80 parts by weight of a glass filler; (C) 1 to 30 parts by weight of a laser direct structuring additive having a reflectance at 450 nm of 25% or above; and (D) 20 to 150 parts by weight of titanium oxide.
Abstract:
A method and an arrangement are disclosed for producing an electrically conductive pattern on a surface. Electrically conductive solid particles are transferred onto an area of predetermined form on a surface of a substrate. The electrically conductive solid particles are heated to a temperature that is higher than a characteristic melting point of the electrically conductive solid particles, thus creating a melt. The melt is pressed against the substrate in a nip, wherein a surface temperature of a portion of the nip that comes against the melt is lower than said characteristic melting point.
Abstract:
A dielectric substrate comprises a resin composition impregnated with non-woven fibrous mat material having a thickness of 5 mils (127 micrometers), wherein the fibrous mat material comprises fibers, having a diameter of 1 nm to 10 μm, that have been extruded through one or more openings to produce fibers that have been collected in the form of a fibrous non-woven mat, and wherein the fibers exhibit a multi-directional orientation in the non-woven mat material. The dielectric substrate is useful in circuit materials, circuits, and multi-layer circuits, economical to make, and has excellent electrical and mechanical properties.
