Abstract
The utility model lies in providing an LED backlight source circuit board, which comprises an aluminum substrate, an insulating layer and a circuit layer, wherein the aluminum substrate is located at the bottom layer and acts as the basis of the overall circuit board, the insulating layer is adhered to the aluminum substrate, the circuit layer (a copper coil) is pressed on the insulating layer, and a printed circuit is formed through etching, thereby being used for realizing assembly and connection of devices. The LED backlight source circuit board is characterized in that the upper surface of the circuit layer is coated by a photosensitive white soldering-resistant ink layer, an LED backlight source is enabled to have the advantages of high reflectivity and reflection uniformity through coating the photosensitive white soldering-resistant ink layer on the circuit layer, and the circuit board is enabled to be high temperature resistant and non-discoloring. The LED backlight source circuit board meets requirements of high temperature resistance, high reflectivity and reflection uniformity for the circuit board of a straight-down LED television or a display because a large amount of LED crystals are installed on the circuit board, and image colors are more uniform, more stable and bright white, thereby being conforming to higher visual enjoyment of consumers.
Description
Technical field
The utility model relates to wiring board technical field, relates in particular to a kind of LED-backlit source wiring board.
Background technology
Straight-down negative be LED uniform crystal particles be configured in liquid crystal panel rear be used as light emitting source, make backlightly can evenly be communicated to whole screen, picture detail is finer and smoother true to nature.Near the favor that the straight-down negative LED TV that is changed to LED crystal grain of CCFL conventional light source crystal grain " flush system " is subject to more high-order consumers.The large scale liquid crystal TV of a direct-light type LED backlight need to be used thousands of LEDs crystal grain, high temperature resistant and reflective the having relatively high expectations of the wiring board to installation LED.In prior art, direct LED backlight wiring board adopts conventional aluminium base circuit board more, and reflectivity is low and reflective inhomogeneous.
Summary of the invention
For the deficiencies in the prior art, the utility model is to provide a kind of LED-backlit source high reflectance and reflective uniform wiring board.
For achieving the above object, the utility model is achieved by following technical proposals:
A kind of LED-backlit source wiring board comprises, aluminium base, insulating barrier, line layer, aluminium base is positioned at the bottom, be the basis of whole wiring board, insulating barrier is bonded on aluminium base, and line layer (Copper Foil) is pressed together on insulating barrier, form printed circuit through etching, for realizing assembling and the connection of device, it is characterized in that, described line layer upper surface is coated with a sensitization white welding resistance ink layer.
Described a kind of LED-backlit source wiring board, preferably: described insulating barrier is the anodic oxidation insulating layer with microcellular structure.
Described a kind of LED-backlit source wiring board, preferably: described line layer comprises basilar memebrane, conducting film and welding film.
Described a kind of LED-backlit source wiring board, preferably: described line layer is provided with prepackage LED pad.
The beneficial effects of the utility model are: make LED-backlit source have high reflectance and the inhomogeneity advantage of reflection by be coated with sensitization white welding resistance ink layer on line layer, and make the high temperature resistant nondiscolouring of wiring board.Met straight-down negative LED TV or display and installed and in the circuit board wiring board is proposed to high temperature resistant high reflectance and reflect uniform requirement because of a large amount of LED crystal, image quality is more uniform and stable, and brilliant white meets the visual enjoyment of consumer Geng Gao.
