When it comes to FPC, many people have a wrong understanding of connectors. That is, FPC connectors and FFC connectors are easily confused by everyone. However, the performance comparison of the two connectors is different, so we should pay attention not to confuse the use of connectors. Otherwise, the circuits of some devices may not be compatible with FPC connectors or FFC connectors. The following briefly introduces the circuit connection instructions of FPC connectors.

1. In the circuit board of the connector, two layers of PI are used in the middle of the copper plate material, with an adhesive that opens windows in specific positions. Then, a double - sided conductor circuit board with a two - layer separated structure in a local area is called a double - sided board generated by the substrate.

2. However, for the circuit board of the double - sided board in the FPC connector, the main thing is to use double - sided PI. After the double - sided circuit is completed, the copper plate material is coated on both sides, and a layer of protective film is added to each side to form a double - conductor circuit board.

3. In addition, the FPC connector also has a substrate - generated single - sided board. It uses pure copper foil material in the circuit process, and then adds a layer of protective film on both sides, resulting in a circuit board with only a single - layer conductor but conductors on both sides of the circuit board. So it is called a substrate - generated single - sided board.

4. In the connector, after the single - sided PI circuit of the single - sided board is completed, the copper plate material is covered with a layer of protective film, and then a flexible circuit board with only a single - layer conductor of the connector is formed.

In the FPC connector, the flat cable is made of PET or other insulating materials and extremely thin tinned flat copper wires pressed through high - tech automated production lines.

However, its wiring has excellent electrical properties, dielectric properties, and good heat resistance. In addition, the wiring has high assembly reliability and quality. The wiring can also reduce the hardware required for internal connections, such as solder joints, trunk lines, ground wires, cables, etc., which are commonly used in the packaging of general connectors. Therefore, when using the FPC connector, higher assembly reliability and quality must be ensured.
