Abstract:
An epoxy resin composition containing as a latent hardener a diaminotriazine-modified imidazole compound and dicyandiamide is improved in the usable life of a solder resist ink composition and can give a solder resist also excellent in resistance to an electroless plating bath.
Abstract:
Als Ausgangsmaterial für elektrische Leiterplatten, das eine möglichst niedrige Dielektrizitätskonstante aufweist und dessen Herstellung einfach und dessen Verarbeitungsparameter problemlos in engen Grenzen konstant gehalten werden können, dienen Glasgewebelagen, die abwechselnd mit mehreren Folien aus vernetzbarem Polyethylen verpreßt werden.

Abstract:
The invention relates to a process for producing insulating laminates and metal clad laminates for electric use by laminating a plurality of reinforcements impregnated with a curable resin, which is characterized by impregnating each of said reinforcements with a liquid curable resin without using a solvent and applying the same liquid curable resin to the surface of the impregnated reinforcements or impregnating each of said reinforcements with excessive liquid curable resin; forming a piled body of said reinforcements; passing said piled body through a slit device to control the quantity of resin existing between the layers of reinforcements; and curing the laminate; thereby providing a laminate comprising layers of cured resin existing between and extending substantially over the reinforcements.

Abstract:
Provided is a process for creating vias for a circuit assembly including the steps of (a) applying a curable coating composition to a substrate, some or all of which is electrically conductive, to form an uncured coating thereon; (b) applying a resist over the uncured coating; (c) imaging the resist in predetermined locations; (d) developing the resist to expose predetermined areas of the uncured coating; (e) removing the exposed areas of the uncured coating; and (f) heating the coated substrate of step (e) to a temperature and for a time sufficient to cure the coating. Also disclosed is a process of fabricating a circuit assembly.
Abstract:
A circuitized substrate (11) comprised of at least one dielectric material (13) having an electrically conductive pattern thereon. At least part of the pattern is used as the first layer of an organic memory device (35) which further includes at least a second dielectric layer over the pattern and a second pattern aligned with respect to the lower part for achieving several points of contact to thus form the device. The substrate (11) is preferably combined with other dielectric-circuit layered assemblies to form a multilayered substrate on which can be positioned discrete electronic components (e.g., a logic chip) coupled to the internal memory device to work in combination therewith. An electrical assembly (71) capable of using the substrate is also provided, as is an information handling system (101) adapted for using one or more such electrical assemblies as part thereof.
