FFC cable: the production process of flexible flexible cable

FFC cable_flexible flexible cable is widely used in the connection between the print head of various printers and the motherboard, the signal transmission and board of plotters, scanners, copiers, audio, LCD appliances, fax machines, various DVD players and other products Board connection. As one of the common electronic components in electronic products, FFC cable _ flexible flexible cable is almost ubiquitous in modern electrical equipment.

The main functions of each component of FFC cable_flexible cable are as follows:

Pad: a metal hole used for welding component pins;

Vias: metal holes used to connect the pins of components between the layers of the FFC cable_flexible cable;

Mounting hole: used to fix the printed circuit board;

Wire: used to connect the copper film of the component pin electrical network;

Connectors: components used to connect between circuit boards;

Filling: copper-clad for ground wire network, which can better reduce impedance;

Electrical boundary: used to determine the size of the circuit board, and all components on the circuit board cannot exceed this boundary.

FFC cable_flexible flexible cable production process:

1. Crimping, conductor layout, insulation film installation, reinforcement board installation, and mold installation on raw materials of corresponding specifications;

2. Heat bonding, start the device, the hot melt adhesive in the inner layer of the insulating film is heated and melted so that the conductors are arranged between the left and right insulating films in an orderly manner, and the conductors are attached to the FFC cable _ flexible flexible cable sandwich. Solidify and shape after rapid cooling;

3. Slitting, according to the corresponding width, the solidified FFC cable_flexible flexible cable is evenly divided into strips and rewinded into rolls;

4. Conduction test, the whole roll of FFC flat cable_flexible flexible flat cable semi-finished product will be tested for 100% electrical performance (short circuit, open circuit).
