Basic Structure Knowledge of FPC Connector and FFC / FPC Flat Cable Connector

1. Fpc Connector is mainly used in LCD, scanner and other electronic equipment, widely used in computer motherboard, LCD display, telecommunication card, memory, mobile hard disk, including mobile devices. In recent years, mobile devices (such as mobile phones, players, recorders, displays, tablets and laptops) are more and more popular in our life. FPC connector is particularly important as a transmission bridge. The specific application products are: automotive electronic connector, vehicle GPS navigation, medical equipment, speaker, digital machine, camera, car audio, TV, typewriter, calculator , cash register, telephone, CD-ROM, VCD, DVD, copier, printer, wireless instrument, call equipment and aerospace products.
Main features: 1) miniaturization, compact and high density integration; 2) space saving; 3) simplified wiring procedure; 4) simple connection; 4) labor cost saving; 5) excellent flexibility, flexible application and foldable.
The conventional spacing of products: ① the distance between the wires: 0.3 mm, 0.5 mm, 0.8 mm, 1.0 mm, 1.25 mm, 2.0 mm, 2.0 mm, 2.54 mm, 2.0 mm, 2.0 mm, 2.5 mm, 2.0 mm, 2.5 mm, 2.0 mm, 2.5 mm, 2.0 mm, 2.5 mm, 2.0 mm, 2.5 mm, 2.0 mm, 2.5 mm, 2.0 mm, 2.5 mm, 2.5 mm, 2.0 mm, 2.54 mm, 2 mm, 1.0 mm, 1.3 mm, 1.

2. FPC connector can be thin and miniaturized in order to reduce the occupied area

The first part of the rubber core, the main role is to protect the terminal, insulation, connection of the correct, to provide the strength of the mechanism

The second part of tongue is mainly used for crimping, insulation and connection, providing strength of mechanism.

The third part of the terminal, the main function is the electronic information conductor transmission function

The fourth part of the grounding plate, the main role is to locate, fix, increase strength and so on

3. FPC package: 1. PVC tube. 2. Carrier packaging

4. FFC / FPC flat Cable Connector: spacing is 0.3, 0.5, 0.8, 1.0, 1.25, 1.27, 2.0, 2.54 mm, 4-50 screen number multi specification series, pH strip connector, XH strip connector, 3.96 strip connector, San strip connector, SCN strip connector, SM strip connector, etc.

Compared with the conventional connector, FPC flexible circuit board has good bending, folding and expansion performance, and can be customized into single and double-sided, 4-layer, layered board, hollow board, etc.
5. The relationship and difference of PC, PCB and FFC
CB is a printed circuit board, or hard board. Its Chinese name is printed circuit board, also known as printed circuit board and printed circuit board. It is an important electronic component, the support of electronic components and the provider of electrical connection of electronic components. Because it is made by electronic printing, it is called "printed" circuit board.
FPC is flexible print circuit flexible printed circuit. In terms of their manufacturing, their lines are formed in different ways
1. FPC is a flexible circuit board with different circuit patterns, single side, double sides and multi-layer structure by chemical etching.
2. FFC is a flat copper conductor sandwiched between two layers of insulating foil. In terms of price, natural FFC is much cheaper. Considering the production cost, more enterprises prefer to use FFC (flexible flat data line).

FPC is a flexible circuit board, referred to as "soft board", also known as "flexible circuit board", also known as "soft circuit board, flexible circuit board" or "soft circuit board, flexible circuit board", English is "FPC PCB" or "FPCB, flexible and rigid flex"
FFC is a flexible Flat Cable. Flexible flat cable (FFC) is a new type of data cable, which is made of pet insulation material and extremely thin tinned flat copper wire, through the production line of high-tech automation equipment. It has the advantages of soft, flexible bending and folding, thin thickness, small volume, simple connection, easy disassembly and easy solution of electromagnetic shielding (EMI).
FFC flexible winding production process: the conductor (tinned copper wire) is made from calender. The width, width and thickness of the conductor are different according to the requirements of the order. After the conductor is made, it is put into the pay off frame (spool) of FFC winding equipment Die) put the conductor into the main equipment of FFC to drive the semi-finished products to conduct vision test after passing through the equipment. After a series of complicated procedures, the FFC flexible flat cable is finally produced through such a series of complicated procedures. Because the actual operation is more difficult, it needs long-term contact with these equipment to reach the level of pure love. According to the level of the actual operator, the quality of FFC cable is also different.

In general: PCB is hard, can not be folded, can be distributed components; FPC is soft, flexible, cloth components; FFC is flexible connection circuit, can not be arranged components.

How to make the enameled wire welded on the PCB board not easy to be broken, which requires continuous bending of 180 degrees for more than seven times?
To prevent bending, it is necessary to keep the bending part of enameled wire from bending, with a certain degree of freedom, and be far away from the welding point. Because enameled wire is soft and not afraid of folding, solder is hard. If it is bent near the solder joint, the service life is not long. As long as the bending place is not hard fold, let him have a little arc. For example, the solder joint of enameled wire is on one side, and it is bent on the other side through PCB board. Or bend part of the sleeve with a heat shrinkable tube or plastic tube.
