An FPTU, or Flexible Printed Circuit Technology Unit, refers to a type of electronic component that utilizes flexible printed circuit boards (FPCBs) to create compact and lightweight electronic devices. These units are often used in applications where space is limited, such as in smartphones, wearables, and other portable electronics. The flexibility allows for complex designs that can be tightly integrated into various shapes and sizes, enhancing the overall functionality and versatility of electronic products.
