Advantages of COB packaging
Release time:
2026-01-21
1. Ultra-light and ultra-thin: Depending on the customer’s specific requirements, PCB boards with thicknesses ranging from 0.4 to 1.2 mm can be used, reducing the weight to as little as one-third of that of conventional products, thereby significantly lowering customers’ costs in terms of structure, transportation, and engineering. 2. Impact-resistant and compression-resistant: COB products directly encapsulate LED chips within recessed light slots on the PCB board, then seal and cure them with epoxy resin. The surface of the light points is raised into a spherical shape, smooth yet highly durable, offering excellent resistance to impact and wear. 3. Wide viewing angle: COB packaging utilizes shallow-well spherical light emission, providing a viewing angle greater than 175 degrees—approaching 180 degrees—and delivering superior optical diffusion and color blending effects. 4. Bendable: The bendability is a unique feature of COB packaging. Bending the PCB does not damage the encapsulated LED chips; thus, COB modules can easily be used to create curved LED screens, circular screens, and wave-shaped screens. They are ideal substrates for personalized display screens in bars and nightclubs. Seamless splicing is achievable, the construction is simple, and the cost is significantly lower than that of flexible circuit boards or traditional display module-based irregular-shaped LED screens. 5. Excellent heat dissipation: In COB products, the LEDs are encapsulated directly onto the PCB board. The copper foil on the PCB board efficiently conducts heat away from the LED chips. Moreover, the thickness of the PCB’s copper foil is strictly controlled by precise manufacturing processes, and combined with the immersion gold plating process, the product virtually eliminates severe light decay. As a result, dead lights are rare, greatly extending the lifespan of the product. 6. Wear-resistant and easy to clean: The surface of the light points is raised into a spherical shape, smooth and hard, making it resistant to impact and wear. If a single point fails, it can be repaired individually. Without a protective mask, dust can be easily removed using water or a cloth. 7. Superior all-weather performance: Employing triple-layer protection, the product exhibits outstanding resistance to water, humidity, corrosion, dust, static electricity, oxidation, and ultraviolet radiation. It meets the demands of all-weather operation and can function normally even under temperature variations ranging from -30°C to +80°C.
1. Ultra-light and ultra-thin: We can tailor PCB boards with thicknesses ranging from 0.4 to 1.2 mm according to the customer’s specific requirements, reducing the weight to as little as one-third of that of conventional products. This significantly helps customers lower their structural, transportation, and engineering costs.
2. Impact and Compression Resistance: COB products directly encapsulate LED chips within recessed light slots on the PCB board, then seal and cure them with epoxy resin. The surface of the light points protrudes into a spherical shape, making it smooth, hard, and highly resistant to impact and abrasion.
3. Wide Viewing Angle: COB packaging utilizes shallow-well spherical light emission, offering a viewing angle greater than 175 degrees—approaching 180 degrees—and delivering superior optical diffusion and soft-light effects.
4. Flexibility: The ability to bend is a unique feature of COB packaging. Bending the PCB will not damage the encapsulated LED chips; therefore, using COB modules makes it easy to create LED curved screens, circular screens, and wave-shaped screens. This makes COB modules an ideal substrate for personalized display screens in bars and nightclubs. They allow for seamless splicing, have a simple construction, and are significantly cheaper than flexible circuit boards or traditionally manufactured LED special-shaped displays.
5. Strong heat dissipation capability: COB products encapsulate the LED chips directly onto a PCB board. The copper foil on the PCB board efficiently conducts heat away from the LED chips. Moreover, the thickness of the copper foil on the PCB board is subject to strict manufacturing specifications. Combined with the gold-plating process, these products virtually eliminate significant light degradation. As a result, lamp failures are extremely rare, greatly extending the product’s lifespan.
6. Wear-resistant and easy to clean: The surface of the light points is raised into a spherical shape, making it smooth, hard, and resistant to impacts and wear. If any individual point becomes damaged, it can be repaired one by one. Without a protective cover, dust can be easily removed with water or a cloth.
7. Excellent All-Weather Performance: Featuring triple protective treatment, this product demonstrates outstanding resistance to water, moisture, corrosion, dust, static electricity, oxidation, and ultraviolet radiation. It is designed to meet all-weather operational requirements and can function normally in temperature ranges from -30°C to +80°C.
