The overall cost of the PCB is affected by copper - the percent can be more than the 10-15% with higher density circuits using more foil and plating. The real cost increase has been in glass costs due to shortages and lack of supply.

It is my understanding that copper constitutes approx. 10-15% of the overall material costs; is this an accurate assessment? If so, how can this be equated to the overall cost of a PCB? According to purchasing, this has been active topic of concern from most of our suppliers, and they are seeking "insights" so as to make an informed decision during this market trend. Any and all feedback would be greatly appreciated.
