Abstract

The invention discloses a low-thermal-resistance and high-radiation metal-base circuit board, which comprises a metal substrate, wherein a circuit layer made of a high-insulation and low-thermal-resistance material is arranged on one side of the metal substrate, and an electric component is electrically connected with the circuit layer; at least one wing of the metal substrate is bent towards the other side without the electric component of the metal substrate to form extension radiation plates, a certain gap is formed between the extension radiation plates to form a counterflow channel; thermal radiation layers are formed on the extension radiation plates; and the metal substrate is integrated with the extension radiation plates. The invention overcomes the shortcomings of the conventional technology and provides a low-thermal-resistance and high-radiation metal-base circuit board with high radiation efficiency and a simple structure.

Description

[technical field] [0001] The invention relates to a circuit board, in particular to a metal base circuit board with low heat resistance and high heat dissipation. [Background technique] [0002] With the continuous advancement of electronic technology, electronic components are increasingly miniaturized and integrated, and the heat generated during the work of electronic components is becoming more and more concentrated and the total amount is also increasing. If there is no good heat dissipation method to conduct the heat generated by the electronic components in time, the temperature inside the electronic components will gradually rise and overheat, the internal stress will increase, the performance will decrease, and the life will be shortened. It may even burn out due to overheating. Therefore, the heat dissipation of electronic components, especially power components, is a problem that cannot be ignored. [0003] The traditional circuit board is equipped with electric...
