The Impact of Inner Layer Residual Copper Rate on Board Thickness

When we were kids, we heard the children's story "The Crow Drinks Water," where a crow raises the water level by dropping stones into a fixed amount of water in a bottle. The same principle applies to multilayer PCB lamination, where during high temperature and high pressure, PP sheets flow in a liquid state to fill the gaps between the layers. This process is called "resin filling." As seen in the diagram, when the copper coverage in the inner layer is minimal, PP sheets of the same thickness need to......
