What is the manufacturing process of micro LED substrates?

When we use micro LED displays, few people think about the complicated manufacturing process behind them. However, the manufacturing process of micro LED substrates is a precise and complex process. Let’s take a deeper look at how micro LED substrates are manufactured.

The first step in manufacturing micro LED substrates is to prepare the required raw materials. These raw materials usually include substrate materials (such as glass, silicon-based materials, etc.), conductive materials (such as copper), insulating materials (such as resin), covering materials (such as light-curing resin), etc. The selection of these materials is critical to the performance and reliability of the substrate.

Before manufacturing micro LED substrates, detailed design and layout work is required. This includes determining circuit requirements, designing circuit schematics, layout and routing, etc. Accuracy during the design phase directly affects the performance and quality of the final substrate.

Once the design is complete, the next step is to print a conductive layer on the surface of the substrate. This is typically achieved by printing conductive ink or metal films onto the substrate surface. The accuracy and uniformity of the conductive layers are critical to the stability of the circuit.

After printing the conductive layer, chemical etching is required to remove excess metal to form the required circuit pattern. This step requires precise control of the concentration and temperature of the chemical solution to ensure accuracy and consistency of corrosion.

After completing the circuit pattern, holes need to be drilled into the substrate to mount the components. These holes may be used for soldering, inserting connectors, or mounting other electronic components. The accuracy and precision of drilling are critical to the stability and reliability of the circuit.

After drilling is completed, a layer of metal needs to be plated on the hole wall to ensure good electrical conductivity and connectivity. This is usually achieved by chemical deposition or electroplating methods.

After completing all manufacturing steps, the micro LED substrate needs to be subjected to final inspection. This includes checking circuit connectivity, uniformity of conductive layers, quality of holes, etc. Only after passing strict inspection can the substrate be considered qualified.

Through the above steps, micro LED substrate manufacturers can produce high-quality, reliable substrates, providing a solid foundation for the application of Micro LED display technology.

How much does a micro LED substrate cost?

The rapid development and widespread application of micro-LED technology makes the cost of micro-LED substrates become increasingly important. However, there are several factors to consider when understanding the cost of micro LED substrates. Let’s dig a little deeper.

The size and selected materials of the micro LED substrate are one of the important factors that determine the cost. Generally speaking, larger substrate sizes and the use of high-quality materials result in higher costs. For example, choosing high-quality substrate materials such as glass substrates instead of conventional substrate materials may increase manufacturing costs.

The number of layers and complexity of micro-LED substrates also have a significant impact on cost. Substrates with more layers and more complex wiring usually increase manufacturing costs. This is because increasing the number of layers increases complexity in the manufacturing process, and complex wiring requires more processing steps and precision equipment.

Production scale is another important factor affecting the cost of micro LED substrates. Generally speaking, mass production allows for greater efficiency and lower unit costs. Therefore, the cost of substrates for mass production may be lower than that for small-scale production.

Manufacturing micro LED substrates requires advanced technology and equipment. Manufacturers incur costs to invest in and maintain these technologies and equipment, and these costs will also be reflected in the final substrate price. Therefore, choosing advanced technology and equipment may result in higher manufacturing costs.

Some customers may have specific customization needs, such as special sizes, special materials, or special process requirements. Meeting these custom requirements may increase manufacturing costs as they may require additional engineering and production adjustments.

To sum up, the cost of micro LED substrates is affected by multiple factors, including substrate size and material, number of layers and complexity, production scale, technology and equipment investment, and customization requirements. Therefore, when selecting a micro LED substrate manufacturer, these factors need to be considered comprehensively to balance cost and quality to achieve the best production cost-benefit ratio.
