Ultra thin flexible PCB for weight-sensitive applications
$45.80
Ultra thin flexible PCB, as its name implies, is thinner than standard PCBs, which is specially designed for cutting-edge applications where space and weight are critical. These flexible circuit boards are generally less than or equal to 0.6 mm thick and have unparalleled flexibility and vibration resistance without sacrificing PCB performance and reliability. Ultra thin flexible PCBs are ideal for aerospace, medical implants, and wearable devices.
