The aluminum based PCB is a metal-based copper clad plate with good heat dissipation function. Generally, the single-side board is composed of a three-layer structure, which is a circuit layer (copper foil), an insulating layer and a metal base layer. Also used for high-end use is designed as a double-side board, the structure is circuit layer, insulation layer, aluminum base, insulation layer, circuit layer. A very small number of applications are multi-layer boards, which can be made of ordinary multi-layer boards combined with an insulating layer and an aluminum base.
Often used in LED lighting products, there are two sides, the white side is soldered to the LED pin, and the other side is in the form of aluminum, generally the thermal conductive paste is applied and the heat conductive portion is contacted.
The surface of power devices is mounted on the circuit layer, and the heat generated during device operation is quickly conducted to the metal substrate through the insulation layer, and then the heat is transferred out by the metal substrate, thereby achieving heat dissipation of the device.
LED lights generally use a single-sided aluminum substrate, the circuit layer is mounted with the LED, and the aluminum base surface on the back can be in good contact with the radiator to dissipate the heat.
The insulating layer in the aluminum substrate is the most critical and the core technology of the aluminum substrate. It must not only bond the copper foil, but also have good thermal conductivity, because the insulation layer is the biggest heat conduction barrier. If you can't quickly conduct the heat of the LED to the aluminum base, and the aluminum base substrate loses its meaning.
Compared with the traditional FR-4, the aluminum based PCB can minimize the thermal resistance and make the aluminum substrate have excellent thermal conductivity. Compared with the thick film ceramic circuit, its mechanical properties are extremely excellent.
Meet RoHs requirements.
More suitable for SMT process.
Extremely effective treatment of thermal diffusion in the circuit design, thereby reducing module operating temperature, extending service life, increasing power density and reliability.
Reduce the assembly of heat sinks and other hardware (including thermal interface materials), reduce product size, reduce hardware and assembly costs; optimize the combination of power and control circuits.
Replaces fragile ceramic substrates for better mechanical durability.
1. Thermal conductivity: Aluminum based PCBs have good thermal conductivity and are suitable for electronic devices that require efficient heat dissipation, such as LED lighting, power supplies, etc.
2. Electrical insulation performance: Aluminum based PCBs have excellent electrical insulation performance and are suitable for high voltage and high frequency application scenarios.
3. Mechanical processing performance: It has good mechanical processing performance and is suitable for industrial applications that require high strength and wear resistance.
Aluminum based PCB are generally stored in a dark, dry environment. Most aluminum based PCB is prone to moisture, yellowing and blackening. Generally, they should be used within 48 hours after opening the vacuum package.
One is the measurement method for dielectric constant and dielectric loss factor, which is the variable Q value series resonance method. The principle is to connect the sample in series with a tuning capacitor to a high-frequency circuit and measure the Q value of the series circuit;
The second method is thermal resistance measurement, which calculates the ratio of temperature difference between different temperature measurement points to thermal conductivity.
