Guangmai LED is professional in making the Chips on Board COB LED 10 Watt.

What is Chips on Board LED?

The COB light source means that the chip is directly bonded and packaged on the entire substrate, that is, N chips are inherited and integrated on the inner substrate for packaging. It is mainly used to solve the problem of low-power chip manufacturing high-power LED lights, which can disperse the heat dissipation of the chip, improve the light efficiency, and improve the glare effect of the LED lights. COB has high luminous flux density, less glare and soft light, and it emits a uniformly distributed light surface.

COB light source is a high-efficiency integrated surface light source technology in which the LED chip is directly attached to a high-reflectivity mirror metal substrate. This technology eliminates the concept of brackets, no electroplating, no reflow soldering, and no placement process, so the process is reduced by nearly three points For one, the cost has also been saved by a third.

The COB light source can be simply understood as a high-power integrated surface light source, and the light emitting area and shape size of the light source can be designed according to the product shape and structure.

Company Introduction

Shenzhen Guangmai Technology Co., Ltd., as the creator of green lighting sources, has 16 years of experience in SMD LED R&D and production, adhering to the concept of perfect quality, striving for perfection, using high-end raw materials in the packaging process, strictly controlling the control process, and strengthening the implementation of reliability. , All aspects simulate the customer's use conditions for experiments, and strive to make quality at the same price.

COB LED advantages:

1. Manufacturing efficiency advantage

The production process of COB packaging is basically the same as the traditional SMD production process. The efficiency of die bonding and wire bonding is basically the same as that of SMD packaging. However, the efficiency of COB packaging is better than that of SMD in terms of dispensing, separation, spectroscopy, and packaging. The product is much higher. Traditional SMD packaging labor and manufacturing costs account for about 15% of the material cost, and COB packaging labor and manufacturing costs account for about 10% of the material cost. With COB packaging, labor and manufacturing costs can be saved by 5%.

2. Low thermal resistance advantage

The system thermal resistance of traditional SMD packaging applications is: chip-die bond-solder joints-solder paste-copper foil-insulating layer-aluminum. The thermal resistance of the COB package system is: chip-bonding glue-aluminum. The system thermal resistance of the COB package is much lower than that of the traditional SMD package, which greatly improves the life of the LED.

3. Light quality advantage

In traditional SMD packaging, multiple discrete devices are pasted on a PCB board to form a light source assembly for LED applications in the form of patches. This approach has the problems of spot light, glare, and ghosting. Since the COB package is an integrated package and a surface light source, the viewing angle is large and easy to adjust, reducing the loss of light refraction. It is also possible to effectively improve the color rendering of the light source without significantly reducing the efficiency and life of the light source by adding an appropriate combination of red chips.
