Understand The Difference Between Aluminum Substrate And PCB

- Aug 05, 2019-

What is aluminum substrate

    Aluminum substrate is a kind of metal substrate copper clad plate with good heat dissipation function. Generally, a single panel consists of three layers, namely, circuit layer (copper foil), insulation layer and metal base layer.This is often seen in LED lighting products.There are two sides, the white side is welded LED pin, and the other side shows the color of aluminum. Generally, the thermal conductivity part will be contacted after applying thermal conductivity coagulation.There are ceramic substrates and so on.


What is PCB board

    PCB board generally refers to printed circuit board.Printed circuit board {PCB circuit board}, also known as printed circuit board, is the provider of electrical connection of electronic components.Its development has a history of more than 100 years;Its design is mainly layout design;The main advantages of using circuit boards are to greatly reduce wiring and assembly errors, improve the level of automation and production labor.

    According to the number of layers of circuit board, it can be divided into single panel, double panel, four layer board, six layer board and other multi-layer circuit board.Because printed circuit board is not a general terminal product, so in the name of the definition of confusion, for example: the motherboard for personal computers, called the motherboard, and can not be 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 are related but can not say the same.For example, the news media call it an IC board because there are parts of an integrated circuit on the circuit board, but it is not the same as a printed circuit board.When we talk about printed circuit board, we mean the bare board - the circuit board without components on it.


The difference between aluminum substrate and PCB

    For some just engaged in aluminum substrate industry partners will always have such a question, that is, aluminum substrate and PCB board what difference, in view of this question below small make up to say specifically to you that there are those differences between the two?

    PCB board and aluminum base board are designed according to the requirements of PCB board in the design, at present in the market of aluminum base PCB board is generally single-sided aluminum base board, PCB board is a big kind, aluminum base board is just a kind of PCB board, is aluminum fund belongs to the board, because of its good thermal conductivity, generally used in the LED industry.

    Generally speaking, PCB is copper substrate, which is also divided into single panel and double panel. The materials used between the two are obviously different. The main material of aluminum substrate is aluminum, while the main material of PCB is copper.Aluminum substrate due to its special PP material.Cooling is better.It's also expensive

    The comparison of the two in heat dissipation, the performance of aluminum substrate in heat dissipation is more superior and PCB board, its thermal conductivity is not the same aluminum substrate is a PCB, the price of aluminum substrate is more expensive.
