FPC is the abbreviation for Flexible Printed Circuit. FPC (Flex PCB Assembly or flexible circuit assembly) printed circuit board assembly (PCBA) and soldering process are very different from rigid PCB boards. 😁
🛠Because Flex PCB lacks rigidity, it is relatively flexible.
If a dedicated carrier board is not used, the transmission cannot be fixed; in addition, basic surface mount technology (SMT) processes such as printing, placement and reflow oven procedures cannot be completed.
