Single-Sided Flex Circuit Boards

Single-sided PCB or single-layer flexible circuits are the most basic type of flexible circuits. They consist of a flexible dielectric film laminated to a  single sheet of copper. The copper layer is then chemically etched according to the specified circuit pattern design. Polyimide coverlays can be added to the circuit board for additional insulation and protection, if desired.


Single-Sided Flex can be used in:

  • Dynamic flexing applications
  • Unusual folding and forming applications
  • Installation/ service applications/ repair
  • Limitations on space/thickness
  • Installation / service flexing


Single-Sided features include:

  • Very thin construction
  • 1 conductor layer
  • Reverse bared or back bared pads
  • Supported and unsupported finger areas
