混合印刷電路板 (PCB) multilayer is a PCB that uses dissimilar 材料 with the intent of optimizing electrical performance and improving system reliability focused towards
高頻 射頻應用. The biggest challenge when manufacturing this type of PCB is managing the different coefficient of thermal expansion (CTE) properties of the dissimilar circuit 材料 both during PCB fabrication and component assembly.
通常，這些設計包括FR-4資料和PTFE層板的組合，允許設計師將射頻功能和射頻功能濃縮在同一PCB上，從而减少設備的占地面積和成本.
