Description
Technical field
The present invention relates to a kind of LED aluminium base panels.
Background technique
The structure in existing LED aluminum base plate face is usually that front end face is set as copper face, and rear end face is set as aluminium face, and copper face upper berth
Equipped with route, and need to etch away copper extra on copper face with alkaline medicinal liquid after completing route, but existing LED aluminum base plate face
Thickness there was only 0.15 μm, such thickness is the corrosion for being not enough to bear etching, causes existing LED aluminum base plate of poor quality
The problem of often occur.
Therefore, how to realize that a kind of anti-etch capabilities are strong, it is simple and reasonable, production process is enormously simplified, is effectively mentioned
High efficiency, the LED aluminium base panel for reducing production cost is technical problem urgently to be resolved in the industry.
Summary of the invention
The main object of the present invention is to provide a kind of LED aluminium base panel, it is intended to realize that a kind of anti-etch capabilities are strong, structure letter
It is single reasonable, facilitate heat dissipation effect, effectively improve production efficiency, reduces the LED aluminium base panel of production cost.
The present invention proposes a kind of LED aluminium base panel, and design feature is, the LED aluminum base plate by being bonded as one and
It is divided into the copper superficial layer of outer surface, the aluminium sheet base composition of the intermediate anti-corrosion flexible layer of insulation and inner surface, insulation from the outside to the core
Anti-corrosion flexible layer is equipped with spaced multiple mesh, after being etched on the outer surface of copper superficial layer by erosion copper liquid medicine and is laid with
There is the lamp bead route for connecting lamp bead.
The anti-corrosion flexible layer of insulation is made of polypropylene plastics, with a thickness of 20-40um.
It is densely covered with multiple mesh on the anti-corrosion flexible layer of the insulation, the aperture of mesh is 0.5-1cm, between the hole of adjoining cells
Away from for 1.2-2.5cm.
It is of the invention to be insulated anti-corrosion flexible layer by setting, good protection can be played to LED aluminum base plate face in etching
Effect, protection effect is excellent, moreover, and be provided with mesh, fully ensure that heat dissipation effect, three is bonded as one, and makes whole
Body has enough intensity, and anti-etch capabilities are strong, simple and reasonable, effectively improves production efficiency, reduces production cost,
It is strong that the present invention realizes a kind of anti-etch capabilities, simple and reasonable, guarantees heat dissipation effect, effectively improves production efficiency, reduces
The LED aluminium base panel of production cost.

Specific embodiment
It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, it is not intended to limit the present invention.
Referring to figs. 1 to Fig. 2, an a kind of embodiment of LED aluminium base panel of the invention is proposed, the LED aluminum base plate is by gluing
Became one and be divided into from the outside to the core the aluminium of the copper superficial layer 100 of outer surface, intermediate insulation anti-corrosion flexible layer 400 and inner surface
Plate base 200 forms, and the anti-corrosion flexible layer that insulate is equipped with spaced multiple mesh 401, leads on the outer surface of copper superficial layer
The lamp bead route 300 for connecting lamp bead is crossed after erosion copper liquid medicine etching and is equipped with, the firm blue electronics in Shanghai can be used in erosion copper liquid medicine
The EL-306 etching solution of Science and Technology Ltd.'s production.
In the present embodiment, it is equipped with route 300 on copper superficial layer 100 and needs to use alkaline medicinal liquid after completing route 300
Copper extra on copper face is etched away, the thickness of LED aluminium base panel is set as 0.35-0.45 μm, moreover, this LED aluminium base panel
Thickness be set as 0.35-0.45 μm, can further improve the etch resistant ability in LED aluminum base plate face 100, anti-etch capabilities are strong,
It is simple and reasonable, production process is enormously simplified, production efficiency is effectively improved, reduces production cost, the present invention realizes one
The anti-etch capabilities of kind are strong, simple and reasonable, enormously simplify production process, effectively improve production efficiency, reduce production cost
The LED aluminium base panel with oxide layer 201.
With reference to Fig. 1 and Fig. 2, the anti-corrosion flexible layer of insulation is made of polypropylene plastics, with a thickness of 20-40um, institute
It states and is densely covered with multiple mesh on the anti-corrosion flexible layer of insulation, the aperture of mesh is 0.5-1cm, and the pitch of holes of adjoining cells is 1.2-
2.5cm, above structure both ensure that the heat dissipation effect of substrate, be also prevented from aluminum substrate by etch damage.
The above description is only a preferred embodiment of the present invention, is not intended to limit the scope of the invention, all utilizations
Equivalent structure transformation made by description of the invention and accompanying drawing content is applied directly or indirectly in other relevant technology necks
