What is aluminum base?
The aluminum substrate is a metal-based copper clad plate with good heat dissipation function. Generally, the single panel 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 on the front and back 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. There are also ceramic substrates and the like.
What is a PCB board?
A PCB board generally refers to a printed circuit board. Printed circuit board {PCB circuit board}, also known as printed circuit board, is the provider of electrical connections for electronic components. It has been developed for more than 100 years; its design is mainly layout design; the main advantage of using the circuit board is that it greatly reduces wiring and assembly errors, and improves the automation level and production labor rate.
According to the number of circuit boards, it can be divided into single-panel, double-panel, four-layer, six-layer and other multi-layer boards. Since the printed circuit board is not a general terminal product, the definition of the name is slightly confusing. For example, the motherboard for the personal computer is called the motherboard, and cannot be directly called the circuit board. Although there is a circuit board in the motherboard, It's not the same, so when you evaluate the industry, you can't say the same thing. For example, because the integrated circuit parts are mounted on the circuit board, the news media called him an IC board, but in essence he is not equivalent to a printed circuit board. We usually say that the printed circuit board refers to the bare board - that is, the board without the upper components.
The difference between aluminum substrate and pcb 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, and the following is a brief explanation of this question. the difference?
The pcb board and the aluminum substrate are designed according to the requirements of the pcb board. At present, the aluminum-based pcb board in the market is generally a single-sided aluminum substrate, the pcb board is a large type, and the aluminum substrate is only a pcb board. One type of aluminum-based metal sheet is generally used in the LED industry because of its good thermal conductivity.
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 clearly 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 due to its PP material. The heat dissipation is better. The price is also more expensive.
The comparison between the two in terms of heat dissipation, the performance of the aluminum substrate in heat dissipation is more superior with the pcb board, and its thermal conductivity is also different. The aluminum substrate is a kind of PCB, and the price of the aluminum substrate is relatively expensive.
