Factors to keep in mind while Manufacturing Multilayer PCBS
There are a number of factors you have to keep in mind while building your Multilayer PCBs. For example, signal integrity and power integrity etc. Copper traces on the PCB allow current to flow through but also has resistance which can, in some cases, alter the current or quality of current which will affect the overall performance of the board. This is why controlled impedance traces are required. The copper thickness should be increased than normal value because these traces can exceed in temperature. In order to control the temperature, the width of the traces is increased accordingly.
