Description

technical field [0001] The invention belongs to the field of substrates, in particular to a metal-ceramic composite substrate and a manufacturing method thereof. Background technique [0002] With the development of high-power and high-density electronic devices, the problem of heat dissipation of electronic devices has become increasingly prominent. Especially in recent years, the application of high-power semiconductor lighting devices, such as light-emitting diodes (LEDs), makes it extremely important to solve the problem of heat dissipation. Since the LED spectrum does not contain infrared parts, the heat generated by the LED chip can only be dissipated through the substrate in the form of heat conduction. [0003] Usually, these electronic devices are generally installed on circuit boards with insulating substrates, for example, metal-based copper-clad laminates that use epoxy resin with low thermal conductivity as insulation and bonding layers, the heat dissipation ef...
