Stiffener |
|
|
In numerous applications involving soldered components, flexible circuits often necessitate external stiffeners (also referred to as reinforcing boards) to provide structural support. These stiffeners can be manufactured from various materials, such as PI (polyimide), polyester film, glass fiber, polymeric materials, steel foil, and aluminum shim, among others. |
|
|
|
|
|
(1)PI or Polyester |
|
|
Polyimide (PI) and polyester films represent widely adopted stiffener materials in flexible circuit board applications. These materials typically feature a thickness of 125μm (5mil), a dimension chosen to balance flexibility with structural integrity by imparting a measurable degree of rigidity to the otherwise pliable substrate. |
|
|
|
|
|
(2)Glass fibers |
|
|
Glass fibers, including FR-4, serve as frequently utilized stiffener materials in flexible circuit board applications. These fiberglass stiffeners exhibit greater rigidity compared to PI or polyester alternatives, making them suitable for applications demanding enhanced structural robustness. Their thicknesses generally span from 125μm (5mil) up to 3.175mm (125mils), offering versatility in design. However, fiberglass presents greater manufacturing challenges compared to PI, and it might not be a standard inventory item for all FPC manufacturers due to these processing complexities. |
|
|
|
|
|
(3)Polymer |
|
|
Polymeric materials, including plastics, are also utilized as stiffeners. These materials are noted for their low water absorption properties and their ability to withstand high pressure and elevated temperatures, making them suitable for applications requiring durability under challenging environmental conditions. |
|
|
|
|
|
(4)Steel foil, aluminum shim |
|
|
Steel foil and aluminum shim provide robust structural rigidity and offer effective heat dissipation capabilities. In design considerations, these materials are primarily selected for their high hardness characteristics or their ability to manage thermal transfer, depending on the specific requirements of the application. |
