The thick film ceramic substrate is produced by screen printing technology. The material is printed on the substrate with a scraper. After drying, sintering, laser and other steps, the heat dissipation substrate of LED grains is formed. Generally speaking, the line made by screen printing is easy to produce rough lines and inaccurate counterpoint because of the problem of screen plate. Therefore, the accuracy of thick film ceramic substrate has gradually failed to meet the requirements of high-power LED products with smaller and smaller sizes and finer lines in the future, as well as LED products with accurate eutectic or cladding processes. Low-temperature co-firing multi-layer ceramic technology, with ceramic as substrate material, the circuit is printed on the substrate by screen printing, and then the multi-layer ceramic substrate is integrated, and finally the heat dissipation substrate of LED grain is formed through low-temperature sintering.
