The difference between aluminum pcb and PCB
What is aluminum pcb
Aluminum pcb is a kind of metal base copper clad plate with good heat dissipation function. Generally, a single panel is composed of three layers of structure, namely the circuit layer (copper foil), the insulation layer and the metal base layer. Commonly seen in LED lighting products. There are two sides, the white side is welding LED pin, the other side is aluminum color, generally smear heat conduction slurry and contact with the heat conduction part. There are also ceramic substrates and so on.
What is PCB board
PCB board generally refers to printed circuit board. Printed circuit board {PCB board}, also known as printed circuit board, is the provider of electrical connection of electronic components. It has a history of more than 100 years; Its design is mainly layout design; The main advantage of using the circuit board is to greatly reduce the error of wiring and assembly, and improve the level of automation and production labor rate.
According to the number of circuit board layers can be divided into single panel, double panel, four layer board, six layer board and other multi-layer circuit board. Because the printed circuit board is not a general terminal product, there is a little confusion on the definition of the name, for example: the motherboard used by personal computers, called the motherboard, but not directly called the circuit board, although there is a circuit board in the motherboard, but not the same, so the evaluation of the industry when the two related but not the same. Another example: because there are integrated circuit parts mounted on the circuit board, so the news media called it IC board, but it is not the same as printed circuit board. We usually say the printed circuit board refers to the bare board - that is, no components on the circuit board.
The difference between pcb and PCB
For some just engaged in the aluminum pcb industry partners there will always be such a question, that is, what is the difference between aluminum pcb and PCB board, for and this question, the following small make up on the specific to tell you that there are those differences between the two?
PCB board and aluminum pcb are designed in accordance with the requirements of PCB board. At present, PCB board in the market is generally single-sided aluminum pcb. PCB board is a large category, while aluminum pcb is only one category of PCB board.
Generally speaking, PCB board is copper substrate, which is also divided into single panel and double panel. The material used between the two is obviously different. The main material of aluminum substrate is aluminum plate, while the main material of PCB board is copper. Aluminum substrate because of its special PP material. Better heat dissipation. The price is also more expensive.
The comparison between the two in terms of heat dissipation, the performance of aluminum pcb in terms of heat dissipation is better than that of PCB board, and its thermal conductivity is also different. Aluminum pcb is a kind of PCB board, and the price of aluminum pcb is more expensive.
