Analysis of advantages of COB packaging
The application of COB packaging has been applied in the field of lighting for many years, and there are many advantages in all aspects, so it has been favored by many lighting companies, then COB packaging technology is applied to the display screen, and what kind of spark will be rubbed out? Will there also be some levels of acclimatization phenomenon? Let's analyze the advantages and disadvantages of COB packaging. It is understood that the application of COB packaging technology in the display screen has incomparable advantages over traditional packaging technology.
1.Ultra-thin and light: according to the actual needs of customers, the thickness of the PCB board from 0.4-1.2mm thickness is used, so that the weight is reduced to at least 1/3 of the original traditional products, which can significantly reduce the structure, transportation and engineering costs for customers.
2. Anti-collision and anti-pressure: COB products directly package the LED chip in the concave lamp position of the PCB board, and then package and cure with epoxy resin adhesive, the surface of the lamp point is raised into a sphere, smooth and hard, crash-resistant and wear-resistant.
3. Large Angle of view: COB package uses shallow well spherical light, the Angle of view is greater than 175 degrees, close to 180 degrees, and has a better optical diffuse color muddy light effect.
4. Bendability: bendability is the unique characteristic of COB package, PCB bending will not cause damage to the packaged LED chip, so the use of COB module can easily make LED curved screen, circular screen, wave screen. It is the ideal base material for personalized modeling screen in bars and nightclubs. It can be seamless splicing, the production structure is simple, and the price is far lower than the LED shaped screen made by the flexible circuit board and the traditional display module.
5. Strong heat dissipation: COB products are the lamp package on the PCB board, through the copper foil on the PCB board quickly wick heat out, and the copper foil thickness of the PCB board has strict process requirements, coupled with the gold sinking process, almost will not cause serious light attenuation. So very few dead lights, greatly extended the life.
6. Wear-resistant and easy to clean: the surface of the lamp is convex into a sphere, smooth and hard, crash-resistant and wear-resistant; There are bad points, can be repaired point by point; No mask, dust can be cleaned with water or cloth.
7, all-weather excellent features: triple protection treatment, waterproof, tide, rot, dust, electrostatic, oxidation, UV effect is outstanding; Meet the all-weather working conditions, the temperature difference between minus 30 degrees to 80 degrees can still be used normally.
