The Role of Electromagnetic Film in FPC
Electromagnetic film is outermost material of FPC and plays a vital role in its performance. Its mai n functions include electromagnetic shielding, lightness, signal integrity protection , and protection of sensitive electronic components. The role of electromagnetic film in FPC is discussed in detail below. 1. Electromagnetic S hielding Electromagnetic film can effectively block electromagnetic interference (EMI) from the outside, thereby protecting the FPC circuit from external electromagnetic fields. This is particularly critical in electronic devices because they are often in a complex electromagnetic environments. 2. Improve S ignal I ntegrity The electromagnetic film can effectively reduce the loss and interference of the signal in the transmission process , so as to ensu re the integrity and stability of the signal s . ...
