With the development of high-speed and high-density circuit board,signal integrity(SI)is becoming more and more important in printed circuit board(PCB)design.Considering the higher requirements for SI in high-speed products,this paper mainly studies the different processing methods of pressing brown-oxide and sold mask pretreatment in PCB processing,as well as the influence of different browning agents and different solder mask pretreatment on SI,which provides data reference for coarsening treatment of high-speed PCB.
