Benefits of Multilayer PCBs (compared to single or double-sided PCBs)

  • Higher assembly density 
  • Smaller size (considerable savings on space) 
  • Increased flexibility 
  • Easier incorporation controlled impedance features. 
  • EMI shielding through careful placement of power and ground layers.

Application of Multilayer PCB

Much of the favoritism toward multilayer PCBs lies in industry trends. With electronics progressing ever toward miniaturization yet multi-functional options, the internal components of those electronics must follow the same trend. While single and double-sided PCBs have proven limited in their ability to balance size and functionality, multilayer PCBs provide a comprehensive solution.
