Aluminum PCB structure is mainly divided into three layers: circuit layer, insulating layer and metal layer. After etching circuit layer form printed circuit, which is used for assembly and connection. Compared with the traditional PCB, if both of them are using the same thickness and same line width, aluminum PCB can carry higher current. The function of insulation layer on aluminum pcb is glue, insulation and thermal conductivity, which is the core technology on metal core pcb. Aluminum printed circuit board insulation layer is the largest thermal conduction of the power structure. The better thermal conductivity of the insulation layer, the more it can help to spread the heat produced during the operation, so it will be better to reduce the operating temperature of the devices, so as to improve the power load of module, reduce the volume, prolong the service life, and improve the power output, etc. There are mainly three different types of metal aluminum base that commonly used, including 1000, 5000 and 6000 series; the basic features of these three series aluminum base are as follows: The production process is single and simple, the price is relatively cheap as well, It is currently the most commonly used series in conventional industry. These days, are most widely used in the market. 1000 series aluminum base determine the range of the minimum aluminum content according to the last two digits, such as series according to the international brand naming principles, its aluminum content must be more than 99.5%, it is unqualified if less than 99.5%. Our country standard (GB/T3880-2006) is clearly stipulated in 1050 must reached 99.5% aluminum content. Alloy aluminum base series which is commonly used, the main elements is magnesium, about 3-5% magnesium element, so it is also known as aluminum and magnesium alloys. The main features are low density, high tensile strength and high elongation rate. Under the same area, the weight of the aluminum magnesium alloy is lower than other series, so is the reason why often used in aviation, such as aircraft fuel tank. In other conventional industries are widely used as well. Aluminum products, applicable to against corrosion, oxidation demanding. The general characteristics of 6061: excellent interface characteristics, easy to coating, high strength, good workability, strong corrosion resistance. 6061 aluminum base typical applications: aircraft parts, camera parts, coupler, ship accessories and metal, electronic components and connectors, etc.PCB manufacture engine which Printed circuits board manufacturer in China, offers Aluminum PCB and FR4 PCB . .
