Do you know the relationship between copper thickness and circuit width & spacing? We know the precision control and performance of a product are paramount, only know that PCB can be built with a nice function, so, to understand the intricate relationship between copper thickness and circuit width and spacing is pivotal. These two parameters are like the gears of a well-oiled machine, interlocking in ways that significantly influence the printed circuit board‘s functionality, signal integrity, and manufacturability. If the designer does not consider the relationship between these two, the design may need to be modified in subsequent production. In order to avoiding this information, let’s embark on a deeper exploration of this dynamic relationship to uncover its nuances and implications now, Frist of all, we need to know some basic information about PCB, like copper thickness, circuit width and spacing. The Essence of Copper Thickness Copper, known for its exceptional electrical conductivity, is the lifeblood of any PCB. The copper thickness refers to the amount of copper deposited onto the board’s surface during fabrication. It’s the foundation upon which the traces, the intricate pathways that carry electrical signals, are built. The standard copper thickness is often measured in ounces per square foot (oz/ft²) or micrometers (µm). Common options include 1oz (35µm), 2oz (70µm), and even higher, it depends on customer’s requirement. http://www.bestpcbs.com/blog/2023/09/do-you-know-the-relationship-between-copper-thickness-and-circuit-width-spacing/
