Abstract:
A method for patterning a plastic surface (1 ), in which the surface is provided with an area different from the material of the surface by the following measures: - a coating (2) is formed onto a plastic surface (1 ) of themoplastic polymer using thermoplastic polymer dissolved or dispersed in water, by applying the water solution or dispersion onto the plastic surface (1 ) and by evaporating the water, - an activating beam (3) is directed to the plastic surface (1 ), and the surface and the activating beam are moved in relation to each other so that at the point of action (P) of the beam, a component in the plastic surface or in the coating absorbs electromagnetic radiation of the beam (3), causing the heating and fusing and mixing of the thermoplastic polymers of the plastic surface (1 ) and the coating (2) at the interface of the coating and the plastic surface to each other so that a permanent bond (4) of the polymer of the plastic surface (1 ) and the polymer of the coating (2) is formed in the range of action of the beam, and - removing the coating (2) from the area left outside the range of action of the beam, by a treatment which leaves the coating (2) more firmly attached to the surface in the range of action of the beam, on the surface.

Abstract:
The aim of the invention is to provide positioning and mounting options with improved handling characteristics even at places that are difficult to access or in other difficult conditions. Said aim is achieved by using functional elements comprising at least one area that can be foamed by supplying energy. At least one of said areas is used as a positioning element for positioning an object or for stiffening flexible or easily bendable materials in a shape-stabilizing manner.
Abstract:
A method of ablating a polymeric substrate by laser means, wherein the laser means emits a laser having a selected wavelength dependant upon the polymeric substrate, and wherein at least 70 % of the incident power from the laser means absorbs within 0.001 inches of the polymeric substrate.
Abstract:
A curable composition which comprises an insulating resin such as an alicyclic olefin polymer or aromatic polyether polymer, a nitrogenous hardener such as 1,3-diallyl-5-glycidyl isocyanurate, and an ultraviolet absorber such as 2-[2-hydroxy-3,5-bis( alpha , alpha ,-dimethylbenzyl)phenyl]benzotriazole is formed into a film by solution casting. This film is superposed on an inner-layer substrate and then cured. Thus, a multilayered circuit substrate is obtained.
Abstract:
The invention discloses methods and apparatus (1) for laser drilling of one or more holes in one or more materials (9) using a laser radiation source (2) emitting radiation having a wavelength or wavelengths, where at least some of the materials (9) have been treated to change their absorption depths at the wavelength or wavelengths of the radiation. The material or materials (9) may be treated by adding one or more dopants thereto. The material or materials (9) may comprise dielectric materials, and may be used in the construction of electrical interconnection packages such as printed circuit or wiring boards, ball grid arrays or multichip modules. The quality of the holes produced is superior so that produced when drilling undoped material with the same laser radiation source.
