Thermoelectric Separation Copper Substrate PCB

Thermoelectric Separation Copper Substrate PCB

Thermoelectric separation copper substrate pcb product introduction:
The thermal conductivity of copper in the metal core PCB manufacturing process is as high as 384W/(m·K), and the thermoelectric separation overcomes the shortcomings of insufficient heat conduction and heat dissipation of the existing single-sided copper substrate. The heat refers to the thermal pad (PAD), and the electricity refers to the positive and negative electrodes. The two are separated by insulating materials to form a special thermal pad. The function of the thermal pad is to conduct heat. The main function of the electrode is to conduct electricity. This packaging method is called thermoelectric separation. , its advantages are many, mainly in the LED heat dissipation design is very convenient. The large exposed copper area in the figure is designed as a large boss, which directly contacts the copper base and directly contacts the heat sink, and the heat is conducted out, which greatly improves the heat dissipation effect. The single-sided thermoelectric separation product can solve the problems of heat generation and light efficiency very well in the use of automobile lamps, and has the advantages of fast heat dissipation, high brightness, and energy saving.



The formation process of thermoelectrically separated metal substrate pcb includes: sticking protective tape on one side of the copper base layer; forming anti-etching ink, exposure, development and etching through the circuit board process, so that the heat dissipation area forms a protrusion, and the height of the protrusion is equal to the insulating layer and the circuit layer. By stacking the circuit layer (copper foil) and the insulating layer (non-adhesive prepreg) together; opening a window in the heat dissipation area of the circuit layer and the insulating layer, which can be opened by die cutting or CNC forming; The heat dissipation layer, the circuit layer and the insulating layer (non-flow glue epoxy prepreg) are pressed together by hot pressing; the circuit layer circuit is produced according to the circuit board processing process, and the thermoelectric separation metal substrate provided by the utility model can be formed. . Thermoelectric separation is suitable for matching with a single high-power lamp bead, especially the COB package, so that the lamp can achieve better results.
Disadvantages of thermoelectrically separated copper substrate pcb: not suitable for single-electrode chip bare die packaging.
The thermoelectric separation copper substrate pcb structure is suitable for high-frequency circuits and areas with large changes in high and low temperatures, heat dissipation of precision communication equipment, and architectural decoration industries, as well as automotive LED lights, miner's lamps, and stage lights. Exposure equipment in industrial equipment and heat sinks of mining machines are all involved in applications.
Thermoelectric separation copper substrate pcb is divided into single-sided thermoelectric separation copper substrate pcb and double-sided thermoelectric separation copper substrate pcb, and now the single thermoelectric separation copper substrate pcb is introduced.
