Abstract:
A method of and device for continuously fabricating a printed circuit laminate or electrically insulating laminate. The method comprises the steps of continuously conveying sheet-like substrates (6) impregnated with a thermosetting resin liquid which produces almost no by-products such as gas, liquid, etc. during the hardening reaction process, laminating the substrates (6), applying coatings (11) to both sides of the laminated substrates at the same time as the laminating step or thereafter, and then allowing the resin to set without the application of pressure.
Abstract:
Provided are: a resin-containing sheet in which not only the mechanical strength of a cellulose nanofiber nonwoven fabric but also the flexural resistance of a substrate are improved; and a structure and a wiring board which include the same. The resin-containing sheet includes: a specific cellulose nanofiber nonwoven fabric (11); a fixing agent (2) which fixes together fibers (1) in the cellulose nanofiber nonwoven fabric (11); and a resin (3) which is in contact with the cellulose nanofiber nonwoven fabric (11) and the fixing agent (2), wherein the storage modulus of the fixing agent (2) is higher than that of the resin (3). The structure is obtained by tightly adhering the resin-containing sheet to a substrate. The wiring board includes this structure.
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:
Provided is a thermoplastic resin molded article excellent in bending strength, flexural modulus and Charpy impact strength, on which the plated layer may be formed in a successful manner. THe thermoplastic resin composition for laser direct structuring comprising, per 100 parts by weight of the thermoplastic resin, 10 to 150 parts by weight of an inorganic fiber and 1 to 30 parts by weight of a laser direct structuring additive, the laser direct structuring additive containing at least one of copper, antimony and tin, and having a Mohs hardness 1.5 or more smaller than the Mohs hardness of the inorganic fiber.
Abstract:
Disclosed are composite build-up materials for the manufacture of printed circuit boards, IC substrates, chip packages and the like. The composite build-up materials are suitable for embedding circuitry such as microvias, trenches and pads. The composite build-up materials comprise a carrier layer (1), a reasin layer without reinforcement (2), and a resin layer with reinforcement (3). The circuitry (9) is embedded into the resin layer without reinforcement (2).
Abstract:
A hot-press cushioning material comprises a non-woven fabric made of a fiber web (4). The fiber web (4) comprises a first fiber (4a) containing a first component having a relatively low softening temperature as a main constituent, and a second fiber (4b) containing a second component having a relatively high softening temperature as a main constituent. The non-woven fabric is compressed at a temperature which is not lower than the softening temperature of the first component but lower than the softening temperature of the second component.
Abstract:
An inorganic material-based article comprising inorganic material-based ultra-fine long fibers having an average fiber diameter of 2 µm or less, and composed mainly of an inorganic component, wherein the inorganic material-based ultra-fine long fibers are collected and contacting surfaces of the inorganic material-based ultra-fine long fibers are bonded to each other not via an adhesive is disclosed.
Abstract:
Thermotropic liquid crystalline polymers are readily ground to smaller particle sizes by using a two or more stage grinding process. The particles produced usually are relatively short, but still, fibers. The ground LCP is useful for rotational molding, powder coating, and forming nonwoven structures.
