What is aluminum circuit board?
The aluminum circuit board is a metal-based copper-clad plate with good heat dissipation function. Generally, the single-sided board is composed of a three-layer structure, which is a circuit layer (copper foil), an insulating layer, and a metal base layer. Common in LED lighting products. There are two sides, the white side is soldered with LED pins, and the other side shows the original color of aluminum. Generally, it will be in contact with the thermally conductive part after applying thermal conductive paste. Currently there are ceramic PCB and so on.
What is Printed circuit board?
PCB board generally refers to printed circuit board. Printed circuit board {PCB circuit board}, also known as printed circuit board, is a provider of electrical connections for electronic components. Its development has a history of more than 100 years; its design is mainly layout design; the main advantage of using a circuit board is to greatly reduce wiring and assembly errors, and improve the level of automation and production labor rate.According to the number of circuit boards, it can be divided into single panel, double panel, four-layer board, six-layer board and other multi-layer circuit boards. The printed circuit board is not a general end product, so the definition of the name is a bit confusing. For example, the motherboard for personal computers is called the main board, and cannot be directly called the circuit board. Although there are circuit boards in the main board, but Not the same, so when evaluating the industry, the two are related but cannot be said to be the same. Another example: because there are integrated circuit components loaded on the circuit board, the news media called him an IC board, but in fact he is not equivalent to a printed circuit board. We usually refer to a printed circuit board as a bare board-that is, a circuit board without components.
The difference between aluminum circuit board and Printed circuit board
For some small partners who have just been engaged in the aluminum substrate industry, there will always be such a question, that is, what is the difference between the aluminum substrate and the PCB board? the difference?PCB board and aluminum substrate are designed in accordance with the requirements of PCB board. At present, aluminum-based PCB boards in the market are generally single-sided aluminum substrates. PCB boards are a large variety. Aluminum substrates are only PCB boards. One type is aluminum-based metal plate, because of its good thermal conductivity, it is generally used in the LED industry.
The PCB board is generally a copper substrate, which is also divided into a single panel and a double panel. The materials used between the two are obviously different. The main material of the aluminum substrate is an aluminum plate, and the main material of the PCB board is copper. The aluminum substrate is special because of its PP material. The heat dissipation is better. The price is more expensiveComparing the heat dissipation of the two, the heat dissipation performance of the aluminum substrate is more superior to that of the PCB board. The thermal conductivity is also different.
