What is the Importance of Copper Thickness in PCB Design
What does PCB copper thickness Mean and why does it matter during the design process? Why are there different sizes such as 0.5oz, 1.0oz, and so on, what are their importance, and do they have a specific application use case? How do it after my design during and after the manufacturing process and is there a certain standard thickness used among designers? Your insight will be helpful to me. Thank You

Is the thickness of the copper layer on a PCB. The copper thickness is a crucial during the design process because it impacts the PCB's electrical conductivity, heat dissipation, and overall reliability.
Copper thicknesses such as 0.5oz, 1.0oz, etc can be used in various PCBs depending on the application. Thicker copper, like 1.0oz or higher, offer better current-carrying capacity making them suitable for high-power applications. Thinner copper like 0.5oz, are more cost-effective and are used in applications with lower current requirements.
The size of the copper thickness all depends on the application and what the designer wants to achieve. But it is essential for the designer to always speak with the manufacturer and explain his needs so he can be guided properly on the right one to use that will suit his design requirements
PCB copper thickness refers to the thickness of the copper layer on the printed circuit board. It is measured in ounces per square foot (oz/ft²) or micrometers (μm). Common thickness options include 0.5oz, 1.0oz, 2.0oz, and so on.
The choice of copper thickness is crucial in the design process due to its impact on various aspects: Conductivity, Current-Carrying Capacity, Heat Dissipation,Cost. After your design, during manufacturing, the chosen copper thickness is implemented by the PCB fabrication process. The manufacturer adheres to the specified thickness during the copper plating step.
Common standards for copper thickness are IPC-6012 for rigid PCBs and IPC-6013 for flexible PCBs. Designers often choose standard thicknesses based on their specific application requirements, and there's no one-size-fits-all answer. For example, 1.0oz copper is often used in general-purpose applications, while 2.0oz or higher might be chosen for high-power applications. It's essential to communicate your specific requirements to the PCB manufacturer and ensure they can meet the desired copper thickness accurately during the manufacturing process.
