Double-Sided Circuits

Double-sided flexible circuits consist of two copper layers encapsulated with dielectric, normally connected with a plated thru-hole (see diagram below). Double-sided circuits can be fabricated with or without coverlayers.

When to use Double-Sided Flex
  • Required when circuit density and layout can not be routed on a single layer
  • Ground and power plane applications
  • Used for shielding applications
  • Dense surface mount assembly
Double-Sided Features
  • Component assembly available on both sides
  • Two conductive layers
  • Can be converted into a Sculptured Flex
