Flexible Printed Circuit (FPC)

Flexible printed circuit consists of conducting layers made of copper foil and insulating layers dielectric that are typically laminate together with polyimide.

The board is used as a substrate for assembling electronics devices and can be bent for specific applications.

Single Side FPC

  • Consists of a single conductor layer of metal or conductive polymer on a flexible dielectric film.
  • Component termination features are accessible only from one side, with holes in the base film for component assembly.

Double Side FPC

  • Consists of 2 conductive layers fabricated with or without plated through holes.
  • When constructed without plated through hole, the connection features are accessible only from one side.
  • Because of the plated through hole, terminators for electronics components are provided on both sides of the circuit, allowing components to be placed on either side.

Multi Layered Flex Circuit

  • Consists of 3 or more layers of conductive and are also known as multilayer flex circuit.
  • Layers are interconnected by plated through hole or openings to access lower circuit level features.
  • Discontinuous lamination is common in cases that require maximum flexibility or bending.

Bare Backed Flex Circuit

  • Bare Back Flex Circuit (double access) has a single conductor layer that allows access to features of the conductor pattern such as lead termination from both sides.
  • This is not commonly manufactured because of the special processing required to provide access to the features discretely.

Rigid Flex Circuit

  • Hybrid constructions consists of flexible and rigid substrates are laminated together into a single structure and then electrically interconnected using plated through hole.

FPC Features

  • Flexible, space‐saving, resolves mechanical constraints, supports dynamic applications.
  • Provides one‐stop assembly service.
  • Full range of products: Single‐Sided, Double‐Sided, Bare Backed & Multi‐Layer board.
  • Split foil (air gap) un‐bond area for increasing flexibility.
