The manufacturing of LED ceramic substrates begins with the selection of raw materials. Typically, the main material of ceramic substrates is aluminum oxide or silicon nitride. These materials have excellent thermal conductivity and electrical insulation properties and are very suitable for high-power LED applications. Manufacturers select high-quality raw materials to ensure stable performance and reliability of the final product.

After the raw materials are prepared, the next step is to print the conductive layer onto the ceramic substrate. This is usually done through screen printing technology, where manufacturers print conductive patterns on the surface of ceramic substrates based on design requirements and circuit layout to enable the connection of electronic components.

After printing, the ceramic substrate needs to be metallized to increase conductivity and connection strength. This step involves depositing a metallic material, such as copper, onto a printed conductive pattern, typically using techniques such as chemical deposition or vacuum evaporation.

After metallization is complete, the next step is to drill holes into the ceramic substrate. Drilling is used to form connection holes and soldering holes on the substrate for mounting electronic components and making circuit connections. Manufacturers use high-precision drilling equipment to ensure accuracy and consistency of hole locations.

After drilling is completed, the LED ceramic substrate needs to undergo a welding process to install the electronic components to the designated position and connect them to the conductive pattern through welding technology. Commonly used welding methods include surface mount technology (SMT) and through-hole welding technology (PTH). Manufacturers will choose the appropriate welding method based on product requirements.
