Key Specifications/Special Features

• Made of a kind of laminated material that has insulation to resist heat, electrical properties, metal foil, and adhesive
• Usually, conductive bumps allow conductivity between the flexible circuit board and another circuit board by pressing the bumps to pads with pressure. This creates electric flow between the systems
• Known for their lightness, thinness, flexibility, and convenience in size.
• Advantages:
  • Tightly assembled electronic packages, where electrical connections are required in 3 axes, such as cameras (static application)
  • Electrical connections where the assembly is required to flex during its normal use, such as folding cell phones (dynamic application)
  • Electrical connections between sub-assemblies to replace wire harnesses, which are heavier and bulkier, such as in cars, rockets and satellites
  • Electrical connections where board thickness or space constraints are driving factors
• Applications:
  • FPCs are often used as connectors in various applications where flexibility, space savings, or production constraints limit the serviceability of rigid circuit boards or hand wiring
  • In addition to cameras, a common application of flex circuits is in computer keyboard manufacturing; most keyboards made today use flex circuits for the switch matrix
