switch PCB manufacturing for high-density networking

Switch PCBs are usually designed with multilayer structures of 12 or more layers and aspect ratios above 9:1 to meet the needs of high-density assembly and complex signal transmission.

Description

The line width and spacing reach 0.075 and 0.090mm, and the hole diameter is 0.225mm, making them suitable for high-density interconnection. Switch PCB manufacturing commonly adopts hybrid pressing processes, mainly using Ultra Low Loss grade high-speed materials mixed with standard FR4 materials to balance signal performance and cost control. The PCB layout usually includes a large number of optical module or high-speed connector interfaces. To meet the requirements of insertion loss and signal integrity for high-frequency and high-speed signals, advanced technologies such as back drilling and resin plug holes + POFV are widely used in the design.
