COB LED display means that it directly adheres the chip to the PCB substrate to make electrical connections. The main purpose of its introduction is to solve the heat dissipation problem of LED displays. Compared with direct plug-in and SMD, it is characterized by saving money. Space, simplified packaging operations, and efficient thermal management. Currently, COB packaging is mainly used in some small-pitch products.

What are the advantages of COB packaging technology?
1.Ultra-light and thin:
According to the actual needs of customers, PCB boards with thicknesses ranging from 0.4-1.2mm can be used to reduce the weight to at least 1/3 of the original traditional products, which can significantly reduce structural, transportation and engineering costs for customers.
2.Anti-collision and compression resistance:
COB products directly encapsulate the LED chip in the concave position of the PCB board, and then encapsulate and solidify it with epoxy resin glue. The surface of the light spot is raised into a raised surface, which is smooth and hard, impact-resistant and wear-resistant.
3.Large viewing angle:
Maipu Guangcai COB package uses shallow well spherical luminescence, the viewing angle is greater than 175 degrees, close to 180 degrees, and has a better optical diffuse light effect.
4.Strong heat dissipation ability:
COB products encapsulate the lamp on the PCB board, and quickly transfer the heat of the wick through the copper foil on the PCB board. The thickness of the copper foil on the PCB board has strict process requirements, plus immersion gold. Craftsmanship, almost no serious light attenuation. Therefore, the lamp rarely dies, greatly extending the life of the lamp.
5.Wear-resistant and easy to clean:
The surface of the lamp point is raised into a spherical surface, which is smooth and hard, and is impact-resistant and wear-resistant. If there are bad pixels, they can be repaired point by point; there is no mask, and dust can be cleaned with water or cloth.
6.Excellent all-weather characteristics:
It adopts triple protection treatment, with outstanding waterproof, moisture, corrosion, dust, static electricity, oxidation, and ultraviolet effects; it meets all-weather working conditions and can still be used normally in a temperature difference environment of minus 30 degrees to plus 80 degrees.
