 Product Description:

The Ceramic PCB for LED Light can also be divided into two types according to the material: an alumina ceramic substrate and an aluminum nitride ceramic substrate. The thermal conductivity of the alumina ceramic substrate is almost 10 times that of the metal substrate, which is nearly 100 times that of the epoxy substrate. The thermal conductivity of the aluminum nitride ceramic substrate is 10 times that of the alumina ceramic substrate, which is 100 times that of the metal substrate. 1000 times the resin substrate. In addition to thermal conductivity, ceramic substrates have many advantages such as high pressure resistance, high temperature resistance, corrosion resistance, low dielectric loss, and the like.

PCB Features:

Ceramic PCB for LED Light have the advantages that other PCBs do not have. They have a very high thermal conductivity, and they are also resistant to corrosion and high temperatures. They are suitable for use on LED Light.

Ceramic circuit boards are widely used, and the most representative ones are the use of LED lights. Everyone knows that the lights are illuminated by electricity. According to statistics, only 20% of electricity will be converted into light, and the rest will be converted into heat. If there is no way to dissipate heat in time, the temperature inside the lamp will be too high, which will greatly shorten the life of LED. This is also restricting the development of LED lamp industry. Problems to be solved. The use of ceramic circuit boards effectively solves the heat dissipation problem of LED lamps. The ceramic substrate has good thermal conductivity: the thermal conductivity of the conventional aluminum-based circuit board MCPCB is 1 to 2 w/mk, and the thermal conductivity of the copper itself is 383.8 w/mk, but the thermal conductivity of the insulating layer is only about 1.0 w/mk. A little better can reach 1.8w/mk, the thermal conductivity of the alumina ceramic substrate is 15 ~ 35 w / mk, the thermal conductivity of the aluminum nitride ceramic substrate is 170 ~ 230 w / mk, the thermal conductivity of the copper substrate is 2w /mk; The aluminum/copper-based circuit board itself has a high thermal conductivity of aluminum, but the aluminum/copper-based circuit board has an insulating layer, resulting in a decrease in thermal conductivity of the entire board. The ceramic circuit board uses inorganic non-conductive ceramic as the substrate, and then the metal directly contacts the ceramic, and the generated heat is quickly transferred to the substrate. Thus, the heat generated by the LED lamp during the illumination process can be quickly dissipated through the circuit board material behind, reducing Damage to ensure better life.
