Flex pcb stiffener material

ByMayo Chen

Flex PCB stiffener materials are used to provide rigidity and support to flexible printed circuit boards (PCBs). Some common materials used as stiffeners include:

  1. FR-4: This is a glass-reinforced epoxy laminate material that is commonly used in rigid PCBs. It provides good mechanical strength and electrical insulation properties.
  2. Polyimide: This is a high-temperature resistant material that is commonly used in flexible PCBs. It provides good flexibility and durability.
  3. PET (Polyethylene Terephthalate): This is a thermoplastic material that is commonly used as a stiffener in flexible PCBs. It provides good mechanical strength and flexibility.
  4. PVC (Polyvinyl Chloride): This is a thermoplastic material that is commonly used as a stiffener in flexible PCBs. It provides good mechanical strength and flexibility.
  5. PI (Polyimide Film): This is a high-temperature resistant material that is commonly used as a stiffener in flexible PCBs. It provides good flexibility and durability.
