Stiffener
In many applications where there are components soldered, the flexible boards require external stiffeners (Stiffener, also known as the reinforcing board) for external support. The stiffener materials are PI or Polyester film, glass fiber, polymer materials, steel foil, aluminum shim and so on.
(1)PI or Polyester
PI and polyester films are commonly used stiffener materials for flexible circuit board. The commonly used thickness is 125μm (5mil), some hardness can be obtained.
(2)Glass fibers
Glass fibers (such as FR-4), which are also commonly used materials for stiffeners. The fiber glass stiffener has a higher hardness than that of PI or Polyester, used where the requirements of harness is higher. The thickness range is typically 125μm (5mil) to 3.175mm (125mils). However, its processing is relatively difficult than PI, and may not be a standing material for some FPC factories.
(3)Polymer
Polymer, such as plastic, etc. is also used as stiffeners.
Its water absorption is low, with high pressure and high temperature resistance.
(4)Steel foil, aluminum shim
The support hardness of steel foil, aluminum shim is high, the heat can also be dissipated. The hardness or heat dissipation in the design is the main concern.
