The Difference Between FPC and FFC?
What exactly is a Flexible Printed Circuit (FPC)？
Flexible Printed Circuit (FPC) is a type of printed circuit that is both flexible and foldable. These circuits are made up of one or more layers of copper traces on a polyester base layer. FPCs can have electronic components attached to the traces and feature overlapping traces. For example, FPC cables come in various pitches, including 0.5mm, 1.00mm, and 1.25mm. They usually have a stiffener attached to the side opposite the contact portion for easier insertion into a connector.
Is it possible to shield a FPC Cable (FPC)?
Indeed, it’s possible to add a EMI shielding layer to an FPC.
What exactly are Flat Flexible Cables (FFC)?
Flat Flexible Cables (FFCs) are composed of several flat conductors insulated with a flexible plastic film, with the conductors arranged in a straight, parallel configuration.
What’s FPC cable and FFC differ from each other?
FPC cable and FFC are frequently mistaken for one another due to their similar flat appearance and data transfer function, but they have distinct differences.
Flat Flexible Cables (FFCs) generally require conductors to be straight through, with pinouts configured as either 1 to 1 or 1 to n.
FPC cables not only perform the functions of FFCs. Moreover, FPCs can feature various pinouts due to their ability to be multi-layered with conductors crossing over each other. They can also have impedance control, making them more suitable for data cables like LVDS. Additionally, FPCs can be designed with bends and angles, not just in rectangular shapes.
Should I choose FPC Cable or FFC?
Choosing an FPC cable and an FFC depends on the specific application.
If considering cost, FFC is relatively more advantageous in terms of price. But FPC cable is more stable and has a relatively longer lifespan. We can assist you in selecting the appropriate cable for your needs.
What is meant by the ‘pitch’ of an FPC and FFC?
Pitch refers to the distance from the center of one conductor to the center of the adjacent conductor.
What’s an FPC/ FFC Connector?
FPC and FFC can be connected to commonly used ZIF (zero insertion force) connectors. Additionally, FPCs can have connectors directly mounted onto their conductors
What types of FPC cables can you produce?
1, FPC Cable with stiffener ( FR4, PI, or Steel stiffener to increase the hardness of specific areas).
2, FPC Cable with EMI shielding, to shielding against signal interference.
3, Keypad FPC cable, with metal keypad.
4, FPC with connectors, used with corresponding connectors according to project requirements.
5, FPC Cable design, support to design all types of FPC cables based on project requirements.
