　　A brief introduction to COB packaging (chip on board packaging, COB)To get brand praise, rental led display It is necessary to have the spirit of constantly improving the quality of products, but also to have a bunch of eternal heart fire. https://szyhfled.com/

　　1. What is COB:

　　COB, or Chip-on-Board, is a cutting-edge packaging method that differs from traditional SMD (Surface-Mount Device) technology. In COB packaging, bare chips are attached directly to the PCB using conductive or non-conductive adhesive. Electrical connections are established through wire bonding, after which the chip and bonding wires are encapsulated with a protective coating. Contrary to the belief that COB eliminates the need for packaging, this method actually streamlines the production process by integrating tasks typically performed by upstream and downstream companies. This means that everything, from packaging to the creation of LED display unit modules or complete display screens, is accomplished within a single facility. This integration simplifies production management, allows for smaller pixel pitches, enhances reliability, and significantly reduces costs, making high-quality LED displays more accessible.

　　The COB (Chip-on-Board) light source is an advanced high-efficiency integrated surface light technology where LED chips are directly mounted onto a highly reflective mirror metal substrate. This approach eliminates the need for traditional support structures, electroplating, reflow soldering, and patch processes, effectively reducing the production process by nearly one-third and cutting costs by the same margin.

　　Essentially, the COB light source is a high-power integrated surface light, with its light-emitting area and dimensions customizable to fit the design and structure of the product it is used in.

　　2. Advantages of COB packaging:

　　1. Ultra-light and thin: Tailored to meet customer requirements, PCB boards with thicknesses ranging from 0.4 to 1.2mm can be used, reducing the weight by up to one-third compared to traditional products. This significant reduction in weight helps lower structural, transportation, and engineering costs for customers.

　　2. Anti-collision and pressure-resistant: In COB products, the LED chip is encapsulated directly into the recessed lamp position on the PCB board, followed by encapsulation and solidification with epoxy resin. This process results in a smooth, hard, and slightly raised spherical surface at the lamp point, making it resistant to collisions and wear.

　　3. Wide viewing angle: COB packaging utilizes shallow, well-spherical lighting, offering a viewing angle of over 175 degrees, nearly reaching 180 degrees. This design provides superior optical diffusion and a more uniform light effect.

　　4. Bendable: Bendability is a distinct advantage of COB packaging. The PCB’s flexibility ensures that bending does not damage the encapsulated LED chip. This makes COB modules ideal for creating LED curved, round, or wavy screens, perfect for personalized displays in bars and nightclubs. The modules allow for seamless splicing, and simple construction, and are more cost-effective compared to traditional display modules and flexible circuit board-based LED special-shaped screens.

　　5. Superior heat dissipation: COB products efficiently dissipate heat by encapsulating the LED directly onto the PCB board. The copper foil on the PCB board rapidly conducts the heat from the LED chip, while the thick copper foil and stringent gold plating processes prevent significant light attenuation. This results in minimal dead pixels and greatly extends the lifespan of the LEDs.

　　6. Wear-resistant and easy to clean: The lamp surface is convex, forming a smooth, hard, and wear-resistant spherical surface. If a pixel fails, it can be repaired individually. Without a mask, the surface can be easily cleaned with water or a cloth, making maintenance straightforward.

　　7. All-weather durability: With triple protection, COB products excel in resisting water, moisture, corrosion, dust, static electricity, oxidation, and UV light. They are built to perform under extreme weather conditions, from -30＜C to +80＜C, ensuring reliable operation year-round.

　　From the plastic restriction order to the plastic ban order, people’s environmental awareness is constantly improving. However, plastic bags are indispensable in supermarkets and homes, so more and more consumers are beginning to pay attention to biodegradable t-shirt bags and fully compostable t-shirt bags. So what are the characteristics of these bags, how do they degrade, and why is there such a significant difference in price?We have every reason to believe. recycle trash bags It will become the mainstream of the industry and will gradually affect more and more people. https://biodegradable-gd.com

　　Different materials

　　Ordinary plastic bags: The main raw material is polyethylene.

　　Biodegradable t-shirt bags: Synthesized by adding a certain proportion of starch, cellulose, photosensitizer, biodegradation agent and other raw materials to non-biodegradable polymer materials.

　　Fully biodegradable bags: PBAT and PLA (polylactic acid, a bio-based degradable material synthesized by fermenting corn into lactic acid and then polymerizing) and starch.

　　Degradation time is different. It takes 200 years for ordinary non-degradable plastic bags to degrade. The various eco-friendly t-shirt bags on the market all refer to those containing plastic components plus specific degradation masterbatch or degradation bacteria. Their form is disintegrated plastic, and there are still plastic molecular structures remaining in the soil and water. Under composting and landfilling conditions, fully eco-friendly t-shirt bags are completely degraded by microorganisms into carbon dioxide, inorganic salts and water within 180 days, directly entering the soil and being absorbed by plants; they can also be degraded in general environments and will not pollute the environment.

　　After understanding the differences between these plastic bags, do you have a new understanding? Now let’s take a look at the advantages of fully biodegradable bags! Using fully biodegradable bags can greatly reduce white pollution; they can also be degraded under composting and landfilling conditions and serve as nutrients for plants. The bag is soft to the touch and uses special process film blowing technology, which has strong toughness and tensile strength; the degradation ability is better than other materials, the life is longer than paper bags, and the cost is lower than paper bags. In addition to the different ingredients, fully compostable t-shirt bags and ordinary plastic bags have the same functions. They can be beautifully printed, of moderate size, and can be packaged for many products. Fully compostable t-shirt bags are soft, wear-resistant, foldable, and have good texture. They can be recycled or composted.
