4OZ ~ 6OZ FR4 Aluminum Immersion Gold Multilayer

What is the standard thickness of the copper layer on the PCB?

 The general double-sided board is 1oz.
The inner layer of the multilayer board is generally 1/2oz 1/3oz and the outer layer is 1oz 1/2oz 1/3oz.
The copper thickness of the power board is required to be higher, generally 2oz, 3oz and even higher are required.
The thickness and width of the circuit copper in the PCB board are mainly designed according to the current. When the average current of the signal is large, the current that the wiring width can carry should be considered. The relationship between the thickness of the copper foil, the width of the trace and the current in the PCB design .

In the PCB industry, OZ (ounces) is commonly used as the unit of copper thickness. 1OZ means the thickness of copper with a weight of 1OZ evenly spread on an area of 1 square foot (FT2). It uses the weight of the unit area to express the average thickness of the copper foil.
In the layout design of the PCB, the units of the circuit board should be analyzed, and the layout design should be carried out according to the starting function. When laying out all the components of the circuit, the following principles should be met:
1. Arrange the position of each functional circuit unit according to the circuit flow, so that the layout is convenient for signal circulation, and the signal is kept in the same direction as possible.

2. Take the core Electronic Components of each functional unit as the center and lay out around him. The components should be uniformly, integrally and compactly arranged on the PCB to minimize and shorten the leads and connections between the components.
3. For circuits operating under the High frequency board, the distribution parameters between components should be considered. Generally, the circuit should be arranged in parallel as much as possible, so that it is not only beautiful, but also PCBA Manufacturing is easy to install and solder, and it is easy to mass produce.
