The forms and structures of connectors today are ever-changing, and with different application objects, frequencies, power, and environments, there are various forms of connectors. FFC connector is a flexible flat cable connector, which is a new type of data cable made of PET insulation material and ultra-thin tinned flat copper wire, and pressed by high-tech automation equipment production line. It has the characteristics of softness, flexible bending and folding, thin thickness, small volume, simple connection, easy disassembly, and easy solution to electromagnetic shielding (EMI). The following mainly discusses the differences between FFC connectors and FPC connectors, as well as the commonly used types of FFC connectors.
The difference between FFC connectors and FPC connectors
The FFC connector is a flexible flat cable connector, while the FPC connector is a flexible printed circuit. From the manufacturing of these two types of connectors, the way their circuits are formed is different:
1. FFC uses two layers of insulating foil with flat copper foil sandwiched between them, resulting in a simpler and thicker finished product.
2. FPC is a flexible circuit board with different single-sided, double-sided, and multi-layer structures obtained by chemically etching FCCL (flexible copper foil).
In terms of price, natural FFC connectors are much cheaper. If production costs are considered, more companies will prefer to use the related designs of FFC connectors.
7 common types of FFC connectors
Type A: Connect both ends and stick the reinforcing plate onto the insulating tape;
Type B: The reinforcing plate is directly pasted onto the insulation tape by crossing it;
Type C: The reinforcement plates at both ends are directly pasted onto the conductor;
D-type: The reinforcing plates at both ends are directly pasted onto the conductor by crossing and pasting them directly;
E-type: One end of the reinforcing plate is pasted on the insulating tape, and the other end is directly soldered;
F-type: The reinforcement plates at both ends are directly attached to the insulation tape, with half of the inside peeled off;
G-type: Both ends are soldered directly.
