COB packaging is a kind of structure that directly installs several LED chips on the heat dissipating PCB substrate to conduct heat. COB packaging combines upstream chip technology, upstream packaging technology and downstream display technology, so COB packaging needs close cooperation among upstream, middle and downstream enterprises to promote large-scale application of COB LED display.
First, the theoretical advantages of COB packaging:
3. Engineering installation: From the application side, COB LED display module can provide more convenient and fast installation efficiency for LED display manufacturers.
2. COB encapsulated LED display has the following characteristics:
1. Ultra-light and thin: According to the actual needs of customers, PCB boards with thickness from 0.4 to 1.2 mm can be used to minimize the weight to 1/3 of the original traditional products, which can significantly reduce the cost of structure, transportation and engineering for customers.
2. Anti-collision and compression: COB products directly encapsulate the LED chip in the concave lamp position of PCB board, then encapsulate and solidify it with epoxy resin adhesive. The surface of the lamp spot is raised into spherical surface, smooth and hard, anti-collision and wear-resistant.
3. Large angle of view: the angle of view is greater than 175 degrees, close to 180 degrees, and has better optical diffuse dispersion and muddy light effect.
4. Strong heat dissipation ability: COB product is to encapsulate the lamp on the PCB board, through the copper foil on the PCB board to quickly transmit the heat of the lamp core, and the thickness of the copper foil on the PCB board has strict technological requirements, coupled with the gold deposition process, it will hardly cause serious light attenuation. So there are few dead lights, which greatly prolongs the life of the outdoor LED display.
COB packaging technology has many advantages, so that LED display manufacturers see the opportunity, many companies have invested in this field, and have finished products on the market.
