Abstract:
Exemplary embodiments of methods and apparatuses to provide an electro-optical alignment are described. An electrical connector is formed on a printed circuit board substrate that extends onto a side surface of the substrate to form an electrical turn. An optoelectronic die is placed onto the printed circuit board substrate. The optoelectronic die on the printed circuit board substrate is erected over a mounting board to provide optical coupling substantially parallel to the mounting board.
Abstract:
Standardized photon building blocks are used to make both discrete light emitters as well as array products. Each photon building block has one or more LED chips mounted on a substrate. No electrical conductors pass between the top and bottom surfaces of the substrate. The photon building blocks are supported by an interconnect structure that is attached to a heat sink. Landing pads on the top surface of the substrate of each photon building block are attached to contact pads disposed on the underside of a lip of the interconnect structure. In a solder reflow process, the photon building blocks self- align within the interconnect structure. Conductors on the interconnect structure are electrically coupled to the LED dice in the photon building blocks through the contact pads and landing pads. The bottom surface of the interconnect structure is coplanar with the bottom surfaces of the substrates of the photon building blocks.
Abstract:
A wiring board (10) includes an insulating substrate (1) having a side surface (1c) including a protrusion portion (1a) or a recess portion (1b) and a lower surface (1d) having a metal member (4) bonded thereto; a wiring conductor (2) embedded in the insulating substrate (1) and having an exposed portion (3) partially exposed above the protrusion portion (1a) or the recess portion (1b) from the side surface (1c) of the insulating substrate (1); and a metal member (4) bonded to the lower surface of the insulating substrate (1). It is possible to suppress occurrence of ion migration between the wiring conductor (2) and the metal member (4) by increasing a distance between the exposed portion (3) and the metal member (4) without increasing a thickness of the wiring board (10).

Abstract:
A method of manufacturing a multi-layer circuit board assembly from a plurality of printed circuit boards is described. Circuits on layers of at least two printed circuit boards are electrically connected by plated via holes drilled through the joined printed circuit board assembly. RF matching pads provided on at least one of the circuits are used to provide the desired insertion loss and impedance characteristics over the desired RF operating frequency band. The need to perform back-drill and back-fill operations can be eliminated by the method described.
Abstract:
In the field of opto-electronic technology, a three-dimensional (3D) light-emitting diode (LED) light-emitting plate is described. The 3D LED light-emitting plate includes an aluminum substrate (1). The aluminum substrate (1) is vertically disposed. Notches (2) are formed on an upper side of the aluminum substrate (1) in a thickness direction. LED chips are mounted in the notches. A flexible circuit layer (6) is disposed on a surface of the aluminum substrate (1). Each LED chip (3) is connected to a circuit of the flexible circuit layer by a gold wire (4). A fluorescent colloid light-emitting shell (5) is disposed outside each LED chip (3) correspondingly. A cavity is formed between the LED chip and the fluorescent colloid light-emitting shell. A lower portion of the fluorescent colloid light-emitting shell is fixed on the aluminum substrate. The 3D LED light-emitting plate effectively improves the luminous brightness and efficiency of an LED and enlarges an effective light-emitting angle, and alleviates the problem of non-uniform light pattern and light color, such that an LED white light lamp can achieve the luminous effect of a tungsten lamp. The fluorescent colloid light-emitting shell wraps the LED chip, which not only protects the LED chip from dust and produces white light, but is also suitable for use in a severe environment. Moreover, the production cost is reduced due to the simple structure.
