摘　　要：PCB信号传输的高速化发展对PCB信号传输的高效与低损提出了更高的要求,高速化也导致了高速产品传输频率的不断增加,而传输频率增加带来趋肤效应和介质损耗的明显加大。文章主要研究在PCB加工中涉及到的粗化处理:压合棕化、防焊前处理采用不同处理方式时对信号线损耗的影响,为高速产品在粗化处理方面提供相关参照依据。The high speed development of PCB signal transmission puts forward higher requirements for the high efficiency and low loss of PCB signal transmission.The high speed also leads to the continuous increase of transmission frequency of high-speed products,and the increase of transmission frequency brings skin effect and dielectric loss.This paper mainly studies the coarsening processing involved in PCB processing:the influence of different processing methods of BrownOxide and Sold-mask pretreatment on signal line loss,providing relevant reference for high-speed products in coarsening processing.
