![]() In general there exist two types of tracks in a PCB. Which means it’s the resulting thickness when 1 oz of copper is pressed flat and spread evenly over one square foot area. ![]() It is measured in ounces and normally the copper thickness of a PCB is 1oz. You usually select Copper Weight with your quote, depending on your project requirements while ordering the PCB. The thickness is determined by PCB manufacturing company standards. A copper trace has a specific width, which we call trace width and has a specific height or thickness. In one of our previous article we have explained about basic PCB terminologies to be aware of for beginners, feel free to give that a read.Īs you might know in a PCB, the copper lines which connect two points on the PCB, are called traces. It is important to understand limitations like these and design your PCB that is within their limitations. For example JLCPCB, a popular PCB manufacturer have their minimum trace width and spacing limit set to 3.5mil for multi layer PCBs. In this article we have put together some important things that you should know about PCB traces and how to design the right traces for your PCB.Īlso one important thing is to remember to check with your PCB manufacturer to see if they can manufacture the board with the given specifications. However when you go up the ladder giving attention to PCB traces is of dire importance. For a beginner who is getting his hands on PCB designing, he may not be too much concerned about characteristics of trace used in PCB. Designing PCBs have become quite easier, thanks to the loads of tools available.
