Ceramic slurry for LED (light-emitting diode) metal substrate and preparation method of LED (light-emitting diode) metal substrate
The invention discloses ceramic slurry for an LED (light-emitting diode) metal substrate and a preparation method of the LED (light-emitting diode) metal substrate. The ceramic slurry consists of ceramic powder, solution, surface active agent and moistening agent. The preparation method of the LED metal substrate includes: 1) selecting a metal plate, burnishing and polishing a printing surface of the metal plate, cleaning and drying it; 2) coating the slurry on the printing surface of the metal plate, sintering and cooling to the room temperature, and forming an insulation layer; 3) coating weldable silver slurry to the surface of the insulation layer, sintering and cooling to the room temperature, and forming a circuit layer; 4) coating solder resist ink at a non-electrode part, mark out positive and negative poles, and then solidify ink. The insulation layer of the ceramic slurry for the LED metal substrate is high in heat conductivity coefficient and good in insulation performance; the insulation layer is coated by the method of silk-screen printing and sintered under medium temperature; the insulation layer at the surface of the metal plate is compact, uniform and smooth; the circuit layer is coated by the method of silk-screen printing and sintered under medium temperature; thus the ceramic slurry is green and environmental-friendly.
