What is a Thick Copper PCB?A thick copper PCB is a high current PCB where both the outer and inner layers of the board contain more than 3 ounces of copper. Even if the total amount of copper in a small kilo is 3 ounces, if the PCB's copper thickness.
Big Dry 4 oz/sq ft, it is also called a thick copper PCB. this abundance of copper is used as an alternative to increasing the thickness of the wires, which is not always feasible. Standard PCB routing for DC motors
Given the thermal constraints, a specific width is usually required to provide the proper level of power. Thick copper PCBs use thicker alignments to accomplish the same job, but with a reduced width.
Today we are not going to talk about nothing else, but briefly about copper thickness should learn how to choose. Select the copper thickness of these "doorway", do you understand?
Copper thickness, refers to the thickness of copper foil, is deposited on the bottom layer of the circuit board, a thin, continuous metal foil layer, which is used to conduct electricity on the printed circuit board. Copper thickness is divided into inner copper thickness and outer copper thickness, measured in weight units Oz, ordinary PCB single board, double board copper thickness of 1 ounce;pcblink 1oz vs 2oz Copper multilayer board outer layer of 1 ounce, 0.5 ounce.
How to choose the copper thickness depends on the use of the PCB, so a variety of options provide users with diverse choices. Take the copper thickness options provided by the official website as an example. On the basis of the original hunting board,how to test pcb board with a multimeter? the new copper thickness options are: double board 1.5oz, four-layer board, six-layer board outer layer 1.5oz, four-layer board, six-layer board inner layer 2oz.(Applicable to TG130 and TG170)
Our company commonly uses 1OZ thick copper printed circuit boards for consumer and communication products, such as light boards, cell phones, digital products, etc., which require a thick copper board, a copper board with a thickness of more than 2 ounces.
Copper has good electrical conductivity and can withstand thermal stress. Some electronic products need to be used in harsh environments and run under high currents, so thermal management is very important. Thick copper PCBs help components dissipate heat, which greatly reduces failures. Advantages of thick copper PCBs include the following.
1. Reduced thermal strain
2. Better electrical conductivity
3. Can withstand repeated thermal cycling on their own
4. Smaller printed circuit board size due to the copper layer
5. Increased strength of connectors.
