Printed litz line
An apparatus includes a substrate and an electronic circuit comprising a plurality of conductive tracts forming a printed litz line on the substrate for distributing a signal therebetween in order to increase effective conductance relative to a single conductive line not divided into tracts. The plurality of conductive tracts may be formed by printing a pattern on the substrate and removing portions of the pattern to leave the plurality of conductive tracts. The removing portions of the pattern may be performed by a removal process such as laser cutting, milling, etching, or masking. For example, the removal may be performed by applying ultrashort laser pulses. The printing may be performed by a jetting process, a spray process, an extrusion process, a dispensing process, and/or other types of processes for applying materials.
Method for making partially metallized precision synthetic thread square mesh fabrics for aesthetic or marking applications
A method for making, by a laser etching, a partially metallized single thread fabric material for aesthetic or marking applications, does not use polymers, inks, pastes and additives. The inventive method comprises a pre-metallizing step or a partial metallizing on the fabric and a following metal removal step, being performed by a quick and localized evaporation thereof, performed either on one or both the surfaces simultaneously, by a specifically designed laser.
Method of implementing stub-less PCB vias
A method and structure are provided for implementing stub-less printed circuit board (PCB) vias and custom interconnect through laser-excitation conductive track structures. Stub-less printed PCB vias are formed which terminate at desired signal layers by controlled laser excitation without stubs or the need to back-drill to remove such stubs.
Patterning and removal of circuit board material using ultrafast lasers
A method for fabricating a printed circuit, comprising: darkening a surface location of a conductive material with one or more ultrafast pulses of laser radiation and ablating the conductive material at the surface location with one or more longer duration pulses of laser radiation to produce traces or micro via patterns on the surface of a PCB. A hole for a blind micro via is produced by ablating the conductive material at the darkened surface location with one or more longer duration pulses of laser radiation and cleaning a second conductive material under the substrate with one or more further longer duration pulses of laser radiation.
Component carrier comprising a photo-imageable dielectric and method of manufacturing the same
A method of manufacturing a component carrier is disclosed. The method includes forming a stack having at least one electrically conductive layer structure and/or at least one electrically insulating layer structure; patterning a front side of the stack using a first photo-imageable dielectric; and patterning a back side of the stack. A component carrier is also disclosed.
Application specific electronics packaging systems, methods and devices
Depicted embodiments are directed to an Application Specific Electronics Packaging (ASEP) system, which enables the manufacture of additional products using reel to reel (68a, 68b) manufacturing processes as opposed to the batch processes used to currently manufacture electronic products and MIDs. Through certain ASEP embodiments, it is possible to integrate connectors, sensors, LEDs, thermal management, antennas, RFID devices, microprocessors, memory, impedance control, and multi-layer functionality directly into a product.
LIGHT SOURCE DEVICE INCLUDING DISCHARGE LAMP, IRRADIATION DEVICE AND DISTINGUISHING METHOD FOR DISCHARGE LAMP
It is intended to provide an irradiation device that can achieve good starting performance even without encapsulating a starting performance promoting substance into the internal space of a luminous tube in a discharge lamp, and simultaneously, can distinguish whether the discharge lamp is a genuine product or not. An irradiation device (50) is composed of a discharge lamp (110) provided as a light source and an ultraviolet light source (200) irradiating ultraviolet light to the discharge lamp (110) to detect whether the discharge lamp (110) is a genuine product or not in activation of the discharge lamp (110).

A touch panel includes a substrate having a display area and a peripheral area. A peripheral circuit is disposed in the peripheral area. The peripheral circuit comprises at least one bonding pad made of a metal layer. A plurality of touch sensing electrodes is disposed in the display area. The plurality of touch sensing electrodes is made of a metal nanowire layer, a film layer disposed on the metal nanowire layer, and a negative-type photosensitive layer disposed on the film layer. The plurality of touch sensing electrodes is electrically connected to the peripheral circuit.
PRINTED CIRCUIT BOARD STRUCTURE INCLUDING A CLOSED CAVITY
A printed circuit board can include a substrate layer, a first metal layer disposed over the substrate layer, a core layer disposed over the first metal layer, and a second metal layer disposed over the core layer, where the core layer defines a closed cavity between the first and second metal layers. Optionally, the cavity is filled with air and operates as an antenna.
