The substrate of a regular rigid PCB is tightly bonded to copper foil, while the surface of the P substrate of FPC is smooth and requires special treatment to ensure that the copper foil adheres firmly. During pretreatment, the P1 film is first etched with a chemical solution (such as sodium hydroxide) to create tiny pits, then coated with a layer of adhesion promoter (similar to "glue"), and finally bonded to the substrate through hot pressing. An experiment conducted by a certain FPC factory showed that the adhesion of pre treated copper foil can reach 0.8N/mm, which is twice that of untreated copper foil, and copper detachment is less likely to occur when bent.
The manufacturing process of FPC is an art of balancing flexibility and rigidity, which not only allows the circuit board to bend like paper, but also ensures the conductivity and reliability of the circuit. With the development of wearable devices, flexible displays, and other fields, the manufacturing process of FPC will continue to advance towards thinner (thickness<0.05mm) and more bending resistant (over 500000 times) directions. In the future, we may see circuits woven like fabric, making electronic devices truly ubiquitous.
