摘要:
In a film carrier with a conductive circuit formed, an opening is formed in a particular position relative to where the conductive path is to be formed. The opening is a through-hole, filled with a conductive material to form a conductive path. The conductive circuit has a concave face, provided according to certain formulae. The film carrier can cope with a fine-pitched and highly dense mounting, while prohibiting pulling out of the conductive path by an external force. The film carrier does not suffer from fallout of the conductive path, and has increased electrical connection reliability.

A manufacturing method of laser processed parts in which at least a pressure-sensitive adhesive layer is provided on a base material as a pressure-sensitive adhesive sheet for laser processing, using a material having specified physical properties. This method comprises adhering the pressure-sensitive adhesive sheet for laser processing to the laser beam exit side of the work by way of the pressure-sensitive adhesive layer, processing the work by irradiating the work with a laser beam of within 2 times of the irradiation intensity for forming a through-hole in the work, at higher than the irradiation intensity of threshold for inducing ablation of the work, and peeling the pressure-sensitive adhesive sheet for laser processing from the work after the machining. Therefore, contamination of the work surface by decomposition products can be effectively suppressed, and laser processed parts can be manufactured easily and at high production efficiency.

The present invention aims at providing a method of manufacturing a patterned resin sheet, capable of implementing efficient and highly precise patterning. The method includes: pressing a perimeter portion of a roller against a surface of a resin sheet with the perimeter portion heated with a laser beam, by using a patterning member that includes a roller rotatable around an axis and has a patterning portion patterned in a recessed and projected geometry on the perimeter portion of the roller, thereby forming on the surface of the resin sheet a pattern that is oriented inversely to the recessed and projected geometry of the patterning portion; and rotating the roller to bring a portion pressed by the perimeter portion into motion, such that the pattern is continuously formed on the surface of the resin sheet.

A method is disclosed for removing a decomposition residue and/or a processing residue, of a material of a resin layer, which is attached to the periphery and inside of holes formed in the resin layer of a printed board. The method provides shooting a laser beam having a wavelength for laser ablation at the holes to thereby remove the decomposition residue and/or the processing residue; reshaping the sectional shape perpendicular to the direction of advance of the laser beam by beam reshaping optics; and shooting the reshaped laser beam to shoot simultaneously all the holes formed in the resin layer and vicinity thereof, wherein the total irradiated area on the printed board is 200%-10,000% of the total sectional area of the holes formed in the printed board. Also disclosed is a method for producing a printed board having holes that provides for: forming holes in a resin layer of a printed board by laser processing and removing a decomposition residue and/or a processing residue, of a material of the resin layer, which is attached to the periphery and inside of the holes.
摘要:
In a mask imaging method (by shooting a laser beam) for forming holes in a resin layer of a printed board, a sectional shape is reshaped by beam reshaping optics. Light path holes corresponding to the holes to be formed in the resin layer are used. The reshaped laser beam shoots the light path holes formed in the mask individually at once. Simultaneous passage of the laser beam through the light path holes formed in the mask is allowed, to form the holes in the resin layer. Exposure of the periphery and inside of a hole to the laser beam results in removal of a decomposition residue and/or processing residue.
