With rapid development and wide use of information technology, design and application of hybrid multilayer PCB are demanded to meet the conditions of signal transmission with high speed or high frequency and to reduce production cost. This paper wants to summarize the pressing technology and the quality improvement of asymmetric mixed lamination by hydrocarbon/ceramic and FR-4, partial hybrid high-frequency materials or mother-board and sub-board, thermal management with embedded coin or carbon composite material or thermal bonding sheet and sub-composited via. The problem of signal transmission such as insertion loss, eye pattern and signal crosstalk of mixed dielectric striplines and the method and results in improving warpage of these high-frequency hybrid multilayer PCB are emphatically introduced at the same.
