Embodiment Construction

[0044] Next, the technical solutions in the embodiments in the embodiments will be described in contemplation in conjunction with the drawings of the present invention.

[0045] See Figure 1 ~ 5 In the present invention, the pre-plastic MINI LED package substrate includes pad 1 and package line structure 2, and the pad 1 is formed by etching, and the gap of the package line structure 2 is filled with a polymer layer 3. The package line structure 2 is integrated with a plurality of pins 4, and the pad 1 is provided with a thermal post 5, and the spacing of adjacent pin 4 is less than 0.3 mm, and the package line structure 2 and the polymer layer 3 are coarse Treatment.

[0046] The flat packaging scheme is used to remove the traditional groove package design, which greatly widened the range of view, and the surface-roughened treatment process, the interface binding force of different materials is used by the specific surface area of ​​the roughness. Increased, enhanced binding powe...

Abstract

The invention discloses a pre-injection molding type MINI LED packaging substrate, which belongs to the field of packaging substrates, and is technically characterized in that the pre-injection molding type MINI LED packaging substrate comprises a bonding pad and a packaging circuit structure, the packaging circuit structure is formed on the bonding pad through etching, a gap of the packaging circuit structure is filled with a macromolecular layer through injection molding, a plurality of pins are integrally formed on the packaging circuit structure, the bonding pad is provided with a heat conducting column, and the distance between every two adjacent pins is smaller than 0.3 mm. The multi-layer etching technology is adopted, the lead distance and the line width can be reduced to 0.07-0.1 mm, the distance of pixel points can be reduced, the resolution ratio is improved, a flat plate type packaging scheme is adopted, a traditional groove type packaging design is removed, the visual angle range is greatly widened, the surface roughening treatment process is adopted, the bonding force between the structures is enhanced, the reliability of the packaging structure is improved, and the heat dissipation capability of the packaging structure can be improved by adding the heat conducting columns made of metal.

Description

Technical field [0001] The present invention relates to the field of encapsulation substrates, and more particularly to a pre-plastic MINI LED package substrate. Background technique [0002] LED screen has a wide range of applications in indoor outdoor. All basic packages are fabricated using a traditional DIP or SMD package structure. The RGB light source chip is packaged together into a pixel point. [0003] With DIP or SMD field, larger pixel points bring a decrease in resolution, and the view angle of the package structure is small, and the interface between different materials also brings a decrease in reliability. . [0004] The traditional stent molding process is used. The encapsulation leads are large (0.3mm), and the line width is also very wide (0.3mm). The pixel point pitch is large, resulting in low resolution, and the form of a cup in the form of a box limit. Width (less than 120 degrees). Inventive content [0005] For the problems present in the prior art, the o...
