What are Flex PCBs?

Flex PCBs, also known as flexible printed circuit boards, are a type of PCB that can bend, twist, and conform to various shapes. They consist of a thin, flexible substrate made of materials such as polyimide or polyester, with conductive traces printed on one or both sides. Flex PCBs offer several advantages over traditional rigid PCBs, including:

• Reduced weight and space requirements
• Improved reliability and durability
• Enhanced electrical performance
• Increased design flexibility

Applications of Flex PCBs

Flex PCBs find applications in a wide range of industries, including:

• Consumer electronics (smartphones, wearables, laptops)
• Automotive (infotainment systems, sensors, lighting)
• Medical devices (implantable devices, diagnostic equipment)
• Aerospace and defense (avionics, satellites, military equipment)
• Industrial automation (robotics, machine vision systems)
