Flex PCB

You should specify that this PCB Manufacturer must have an established and up-to-date process flow for producing flexible circuit boards if you need them to manufacture flexible PCBs for you. 

Physically, flexible printed circuit (FPC) board is identical to a PCB with components; the only distinction is that the substrate for FPC boards may be bent. Similar components can be put on an FPC, and it can achieve the same functionality as a regular rigid PCB. A flexible circuit board is constructed using unique plastic substrates. It might be polyester or polyimide film. You may occasionally notice a polyester sheet with silver conducting lines on it; we shall explain which material is utilized in flexible PCB in more detail later. Provide electronic manufacturing services.

Applications

Numerous applications where reliability, compactness, and flexibility are important use flexible PCBs. It is utilised in numerous applications because it can fit into any available space and because it has benefits that other forms of PCBs do not. Flexible circuits are commonly employed in the automotive industry. It’s because the PCB must endure shocks and vibrations when cars are running on the road. A stiff PCB cannot persist for a long time in this situation. Flexible circuits are therefore recommended.  Flexible circuits are used in several items ems electronics that we use on a daily basis, including calculators, household appliances, music players, printer, televisions, and many more. These circuits improve the performance, reliability, and compactness of the devices.

There are some differences in the flexibility, smoothness, and cost of rigid and flexible PCBs, although the manufacturing method is the same for both. When it came to material handling, preparing Flex PCB necessitates certain additional steps. In order to prevent any cracked jointing when the circuit is bent, precise requirements are also required. More expensive than rigid PCBs are flexible PCBs. But since we are only talking about the operating cost of the flexible PCB here, it is possible that the entire cost of the project utilizing rigid PCB will be more than the expense of the flexible PCB. However, each flexible PCB will cost more money.
