Aluminum plate is a metal base copper clad laminate with the following characteristics such as terrific thermal conductivity, machining property and gas-electric insulation performance.
Generally, there are three standands to gauge appropriately aluminum plate: Thermal conductivity, thermal resistance value and withstanding voltage.Therefore, when it comes to choosing the aluminute plate for the PCB where the above three standards is a major consideration.
Here are some parameters for your reference:
Board thickness:0.2-6.0 mm;
Copper foil thickness: 0.5–6.0 oz;
Thermal conductivity: 1.0–8.0;
Withstanding voltagel: 500V, 250V, etc.
Thermal resistance value:
Common aluminum plate: >1;
High thermal conductivity aluminum plate: <0.5 or <0.1 or less
In a nutshell, high thermal conductivity and low thermal resistance are the crucial factors when you are looking for suitable aluminum plate for the PCB.
The application of metal substrate provides a new way to solve the heat dissipation of LED effectively.At Aluminum PCB you can get aluminium core PCBs with a thermal conductivity of 1.0 W/mK to 8 W/mK. The aluminium core helps to distribute the selective heat of heat-intensive components and to make the heat development on the printed circuit board more homogenous.
