　　A brief introduction to COB packaging (chip on board packaging, COB)period rental led display Many adjustments have also been made, and the direction of product research and development has been reversed, in order to better meet the market demand. 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.

　　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.

　　Recently, a sales partner encountered a difficult problem. The optical module received by the customer could not be used. After much research, the reason was found. It turned out that the customer purchased an optical module with a heat sink, which did not match the existing network card slot. What is the difference between the flat top and the heat sink top of the optical module? How to choose when using it? Let’s follow the editor to take a look!To get brand praise, 400g qsfp-dd 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://www.3coptics.com/

　　1. The difference between the flat top and the heat sink top of the optical module

　　The flat top and heat sink top in the optical module usually refer to two different structures in the optoelectronic device:

　　Flat-top: Flat-top structure usually refers to the flat top structure of the laser or optical transmitter in the optical module. This design allows light to propagate and focus more easily, which is conducive to more efficient transmission of optical signals in optical fibers or other transmission media. The flat-top design can improve the coupling efficiency and transmission efficiency of light, and is more common in some high-performance optical communications or optical sensors.

　　Heatsink-top: Heatsink-top structure usually refers to the top design of laser or optoelectronic device with heat sink. These heat sinks are usually used to effectively dissipate heat to keep the device operating temperature within a safe range. In high-power or high-density applications, the device may generate a lot of heat, which needs to be transferred to the surrounding environment through the heat sink to prevent the device from overheating and damage. Therefore, the heat sink design is crucial for the long-term stable operation of the optical module.

　　2. How to choose the flat top and heat sink top of the optical module

　　With the increase of transmission rate, the size of the optical module is gradually miniaturized, and the requirements for internal optical devices are getting higher and higher. It is very necessary to solve the heat dissipation problem. The flat top and heat sink top of the optical module each have their advantages. Which one is better depends mainly on the transmission rate, interface type, packaging method and specific application scenarios and requirements.

　　Transmission distance and rate requirements: If your application requires long-distance high-speed transmission, the flat-top structure may be more suitable because it is conducive to improving the coupling efficiency and transmission efficiency of light. For short-distance or low-speed transmission, the heat sink top structure can be considered more.

　　Thermal management requirements: If the laser or optoelectronic device in your application needs to handle a lot of power or high-density energy, the heat sink top structure may be more important because it is conducive to effective heat dissipation, thereby maintaining the stable operation of the module and preventing overheating from causing performance degradation or damage. Especially in applications such as high-power optical communications or lidar, good thermal management is essential.

　　Cost and complexity: The flat-top version of the optical module has a simple design and no additional heat sink structure, because it focuses on the light transmission efficiency, while the heat sink top structure may require a more complex design and manufacturing process to ensure good heat dissipation performance. Therefore, you need to weigh these two options when considering cost and complexity.

　　Environmental conditions: Consider the environmental conditions in which your application will operate. If the ambient temperature is high or there may be other heat sources, good heat dissipation may be more important.

　　Reliability and stability requirements: If your application has high requirements for long-term stable operation of the device, it may be more appropriate to choose a heat sink top structure that can provide good thermal management.

　　Identifying the quality of LED electronic screens requires more than just looking at the main components like LEDs and ICs. While these components are crucial, they are not the only factors determining the screen’s overall performance and longevity. Here¨s a refined guide to help you make informed decisions when choosing an LED electronic screen:With the expanding influence of the industry, rental led display Our business is also constantly spreading, and the development of the market is also gradually advancing. https://szyhfled.com/

　　led screen quality

　　Common Misconception

　　Many people believe that the lifespan of LEDs and ICs, which can reach up to 100,000 hours, guarantees a screen¨s durability if it operates 24/7. However, this is a necessary but not sufficient condition. The proper use of red, green, and blue lamps, along with the optimal adjustment of ICs, plays a vital role in achieving a high-quality display. Just as a high-end engine doesn¨t guarantee a top-performing car, the key lies in how well all components work together.

　　Temperature Sensitivity

　　LEDs and ICs, being semiconductor devices, function best at around 25≧. However, in outdoor environments, temperatures can vary drastically, from over 60≧ in summer to below -20≧ in winter. Manufacturers often test products at 25≧, but real-world conditions can cause significant performance variations. For instance, at high temperatures, the brightness of LED lights may decrease unevenly, leading to a distorted or “flowery” display. Similarly, if the temperature in the cabinet exceeds 85≧, the IC may become unstable, further affecting the screen’s quality.

　　Power Supply Considerations

　　The power supply is another critical factor. Its stability, output voltage, and load capacity can vary under different temperatures, directly influencing the screen¨s performance. A reliable power supply ensures consistent operation and supports the screen¨s overall quality.

　　Cabinet Design

　　The design of the cabinet is equally important. It not only provides circuit protection and safety but also affects ventilation and heat dissipation. As the screen operates, thermal drift can degrade image quality over time, making effective heat management essential.

　　Environmental Impact

　　Outdoor LED screens face additional challenges, such as temperature fluctuations, UV radiation, and humidity. Over time, these factors can cause deformation in materials like ABS masks, iron boxes, and connectors, leading to issues such as light blockages, unreliable solder joints, and signal interruptions. The result is often a screen that fails to maintain its original quality and consistency.

　　Finding a reliable biodegradable milk tea bag involves considering several factors to ensure the product meets your quality, sustainability, and usability requirements. Here¨s a guide to help you find the best options.Gold and silver are not as good as clear waters and green mountains. This is an environmental protection slogan put forward in recent years. When you order milk tea at home or in the office, you will get a packaging bag. A small packaging bag may not have any impact on the environment, but when people gather together, so many people order milk tea every day. Over time, the pollution caused by this plastic milk tea bag to the environment is still very serious, because ordinary Plastic can exist in nature for hundreds of years. If it is burned, it will also produce dioxins and other pollutants, causing serious damage to the environment.In addition to domestic, biodegradable mailing bags It has also emerged in the international field and gradually gained the favor of more foreign friends. https://biodegradable-gd.com

　　For the sake of environmental protection, the country has strictly restricted the production and sale of disposable plastic products such as plastic shopping bags since January 1, 2021, referred to as the “Plastic Ban”. As a result, supermarkets, restaurants, milk tea shops and other places have replaced plastic shopping bags with biodegradable bags to meet environmental protection requirements.

　　Among the solutions to replace plastic products, biodegradable materials have attracted everyone’s attention. Because the raw material of biodegradable milk tea bags, polylactic acid PLA, comes from plants such as corn and potatoes, and the source of raw materials is very environmentally friendly and natural. After use, biodegradable milk tea bags can be degraded into carbon dioxide, water and other substances in the landfill in about 180 days. They will not become “white garbage” like plastic bags and pollute the environment. With the implementation of the plastic ban, many milk tea shops have assumed the responsibility of environmental protection and have replaced plastic bags with compostable milk tea bags.

　　Therefore, when purchasing biodegradable products, you must carefully identify them. Here are some simple identification tips:

　　1. Choose products from large manufacturers, which are more reliable and reduce the risk of buying by mistake.

　　2. Read the ingredient description. When purchasing biodegradable milk tea bags, we can ask the manufacturer about the ingredients of the bags, which are generally polylactic acid (PLA), polyadipate (PBAT), and starch. Others such as PE+starch are pseudo-degradable. Relevant documents stipulate that degradable materials cannot contain plastic components such as PE, PP, PVC, and PET. Products such as PE+starch and PE+photooxidant are pseudo-degradable and need attention.

　　To find a reliable compostable milk tea bag, focus on verifying the materials, assessing environmental impact, evaluating quality, and considering brand reputation. By doing thorough research and possibly testing samples, you can ensure you choose a product that meets your needs while contributing to environmental sustainability.We are both victims and beneficiaries of environmental protection. For environmental protection, we can start with small things around us, starting with using one less plastic shopping bag and one less plastic straw.
