A component carrier includes a carrier body formed of a plurality of electrically conductive layer structures and/or electrically insulating layer structures, a metal surface structure coupled to the layer structures and a metal body directly on the metal surface structure formed by additive manufacturing.

A manufacturing apparatus that includes a conveyance device that moves a stage, where an electronic device shaped by multiple layers is placed, in X-axis and Y-axis directions. A first shaping unit, a second shaping unit, and a component mounting unit are arranged within a range in which the stage can move. The manufacturing apparatus performs additive manufacturing of the electronic device on the stage by performing a sequential movement of the stage to respective working positions of different units. As a result, in this manufacturing apparatus, a workpiece on the stage does not have to be removed and repositioned during each work process such as shaping by a first shaping unit, shaping by a second shaping unit, and electronic component mounting by a component mounting unit.

Electronic device having at least one main antenna (1) where such antenna is formed as a conductive layer on walls of a housing (10) of the electronic device through a laser direct structuring process and has a first portion (2, 3) on an internal part of the housing, a second portion (4) forming a junction area on an edge between an interior part and an exterior part of the housing and a third portion (5) on an outer part of the housing in electrical continuity with the first portion through the junction area.

A method for manufacturing a semiconductor package structure is provided. The method includes: (a) providing a semiconductor structure including a first device and a second device; (b) irradiating the first device by a first energy-beam with a first irradiation area; and (c) irradiating the first device and the second device by a second energy-beam with a second irradiation area greater than the first irradiation area of the first energy-beam.

A metal foil has a cathode surface on which no linear indentations exist when viewed microscopically, a production method for the same, and a processing method for an electrodeposition drum used for the same. A surface of the electrodeposition drum for producing the metal foil is irradiated with a laser to process this surface into a pattern of repeated curved shapes including a plurality of dot-shaped dents or the like. With this, the pattern of repeated curved shapes is formed on the surface of the electrodeposition drum. The electrodeposition drum thus processed is used as a cathode, supply of electricity is provided between the electrodeposition drum and an anode plate that are soaked in an electrolytic solution to electrodeposit metal on the surface of the drum with an electrolytic reaction, and thereafter, the metal is peeled off from the electrodeposition drum, thereby yielding the metal foil. The metal foil thus obtained has a pattern corresponding to the pattern of repeated curved shapes including a plurality of dot-shaped bumps or the like on the cathode surface thereof.

A method for circuit fabrication includes defining a solder bump, including a specified solder material and having a specified bump volume, to be formed at a target location on an acceptor substrate. A transparent donor substrate, having a donor film including the specified solder material, is positioned such that the donor film is in proximity to the target location on the acceptor substrate. A sequence of pulses of laser radiation is directed to pass through the first surface of the donor substrate and impinge on the donor film so as to induce ejection from the donor film onto the target location on the acceptor substrate of a number of molten droplets of the solder material such that the droplets deposited at the target location cumulatively reach the specified bump volume. The target location is heated so the deposited droplets melt and reflow to form the solder bump.

A hot wind is blown to a land and a lead from the underside of a printed board, to perform preheating. At the start of preheating or after start of preheating, a laser beam is applied to a soldering point, and meanwhile, wire solder is fed to a position contacting with the soldering point. The fed wire solder is melted by the laser beam. After soldering is finished, feeding of the wire solder is stopped. Application of the laser beam is stopped, to solidify the melted solder.

The present invention relates to a method for manufacturing an electronic or electrical system, the method comprising the layer-free production of at least one physical structure (101, 102) which is designed to guide electromagnetic waves, using at least one additively operating apparatus, wherein the layer-free production of the spatial, layer-free structure comprises the simultaneous or sequential application and/or removal of one or more materials in the spatial arrangement, as a result of which the electronic or electrical system is partially or completely formed. The invention further relates to a system which is manufactured in accordance with the method.

Discussed is a battery pack including a battery cell that can include a pair of electrode leads including a positive electrode lead and a negative electrode lead, a pack housing configured to receive the battery cell therein, and a protection circuit module (PCM) having a protection circuit formed on a printed circuit board (PCB), the protection circuit being configured to control operation of the battery cell, wherein the pair of electrode leads may be directly bonded to a surface copper foil layer of the PCB. The pair of electrode leads may be directly bonded to the surface copper foil layer of the PCB by a laser welding.

A process for making a circuit board modifies a catalytic laminate having a resin rich surface with catalytic particles dispersed below a surface exclusion depth. The catalytic laminate is subjected to a drilling and resin-rich surface removal operation to expose the catalytic particles, followed by an electroless plating operation which deposits a thin layer of conductive material on the surface. A photo-masking step follows to define circuit traces, after which an electro-plating deposition occurs, followed by a resist strip operation and a quick etch to remove electroless copper which was previously covered by photoresist.
