COB Single color LED Strip

Product Description:

COB means Chips on Board, which means that the chips are directly encapsulated on the flexible PCB board, and the COB led strip is a strip of chips encapsulated on a flexible board. The chips are mostly flip-chips, which are linearly fixed on the PCB board, and then a layer of encapsulation glue mixed with phosphor is directly dropped on the surface of the chip. The light emitted from the chip is refracted, reflected, and interacts with the phosphor, and the glue emits different colors and color temperatures of light evenly.
So, COB LED strip light is also called continuous led strip light or dotless led strip lights.

Easton Technology Co., Ltd.'s COB LED Strip products include  320leds/m,336leds/M,480leds/M，504Leds/M，512leds/M. These products are available in12V & 24V specifications. They can also provide multiple protection levels such as IP20/IP65/IP67/IP68, and can be used in different application scenarios. Easton Technology can also provide power supplies, controllers, aluminum profiles and other related accessories. In addition, Easton Technology also provides customized services, including wire length, PCB width, LED QTY, connector specifications, logo, packaging, LED light strip length, etc.

COB LED Strip Features：

1.) High-density LED chips provide continuous, uniform light with virtually no graininess, creating a visual effect of "seeing light without seeing the lamp."
2.) Beam Angle: Typically up to 180 degrees, providing a wider illumination coverage area.
3.) Color Rendering Index (CRI): Generally high (CRI 90+), resulting in more realistic color reproduction.
4.) Stability: The circuit design ensures that a single chip failure will not affect overall operation, and the strip also offers enhanced anti-static and anti-sulfurization properties.
5.) Flexibility: The strip itself is flexible, making it easy to install on curved surfaces or in corners.
6.) Cuttability: Typically can be cut to specific lengths for easy customization.
7.) Heat Dissipation: Due to the dense chip density, the power per meter should be kept to a minimum (recommended ≤15W/m). Consider heat dissipation requirements.

The production process of COB led strip products of Easton Technology Co., Ltd. is:

1.) First coat the PCB pads with solder paste through an automatic solder paste machine. The coating uniformity and thickness of the solder paste determine the quality and flatness of the soldered chips, as well as the quality of the soldered chips; Apply solder paste

2.) Load the PCB board coated with solder paste on the carrier, input and set the die-bonding program of the chip through computer programming, adjust the direction and height of the die-bonding, and confirm the electrode direction of the chip;

3.) Do a small-batch die-bonding test first, and inspect the appearance quality of the solid-bonded PCB to determine the direction of the die-bonding, whether there is solder paste connected, and whether the position of the die-bonding is correct, and the inspected product will flow into the next process. ;

4.) Put the solid crystal PCB board and wafer into reflow soldering, set the temperature and speed of reflow soldering, solder the LED chip firmly in the reflow soldering, and conduct an electrical test after being released to test whether the LED chip emits normally. ;

5.) After testing the LED chip on the PCB board, carry out the powder mixing process of silica gel and phosphor powder, according to the photoelectric parameters such as color temperature and brightness specified by the customer, carry out different proportions of configuration, and carry out positive air defoaming of the prepared glue

6.) Fix the PCB board on the glue dispenser carrier for the glue dispensing process. The glue dispensing process is the most critical process for the success of the light strip. After dispensing, put the PCB board into the oven for baking. The glue from different manufacturers If the baking conditions are inconsistent, you must refer to the manufacturer's requirements for verification before setting the appropriate baking temperature.

7.) After the glue is dispensed, test the photoelectric parameters of the light strip to see if the test data meets the customer's requirements.

8.) After welding the 0.5-meter PCB board, connect it to the requirements ranging from 5-10 meters;

9.) Aging detection

10.) Pack the light strip with a reel after testing the adhesive;

11.) Check again after the reel, put it in an electrostatic bag, and pack it into a box
