Abstract:
A method for manufacturing a chip-mounting substrate includes a pre-coating step of forming a precoat on a substrate including a plurality of conductive portions and an insulating portion interposed between the conductive portions, an etching step of etching at least a portion of the precoat through a laser to form a pattern, and a step of forming a metal layer on the substrate. The pattern is disposed on at least one of the conductive portions, and the metal layer is formed in the pattern.
Abstract:
A chip substrate includes at least one insulation portion interposed between conductive portions. A cavity formed in a recessed shape from a region of an upper surface of the chip substrate exposes a top surface of a part of the at least one insulation portion. An insulation layer is coated on the upper surface of the chip substrate excluding the region of the cavity. A bump may be formed at a predetermined height within the cavity.
Abstract:
Disclosed is a chip-mounting substrate. The chip-mounting substrate includes a plurality of conductive portions configured to apply voltages to at least two or more chips to be mounted, a plurality of insulation portions formed between the conductive portions and configured to electrically isolate the conductive portions, and a cavity formed in a region which includes at least three or more of the conductive portions and at least two or more of the insulation portions and depressed inward to form a space in which the chips are mounted.
Abstract:
A light engine for a light emitting element includes an element substrate on which a plurality of light emitting elements is mounted, a plurality of circuit substrates connected to one another in an insulated state in order to apply a drive voltage to the light emitting elements and connected to the element substrate in an insulated state, and a plurality of protection substrates configured to surround the element substrate and the circuit substrates and to make contact with the element substrate and the circuit substrates in an insulated state.
Abstract:
A chip substrate includes: a conductive layer being stacked in one direction and constituting a chip substrate; an insulator being alternately stacked with the conductive layer and electrically separating the conductive layer; and a lens insert having: a depression reaching down to a predetermined depth from a specified area of an upper surface of the chip substrate overlapping with the insulator; and a predetermined number of sides on the upper surface wherein arcs are formed at regions where the sides are met with each other. Since the space for inserting a lens can be formed to have a shape comprising straight lines, and a lens to be inserted can also be manufactured in a shape comprising straight lines, therefore the manufacturing process for a lens to be inserted into the chip substrate can be further simplified.
