1.27mm Ptch FFC cable

Advantage of 1.27mm pitch FFC cable are Small size, light weight, the design of the cable board is used to replace the larger wiring harness wire. In the current patch electronics assembly board, the insulation material FFC cable is usually to meet the miniaturization and mobility requirements Of the solution. By using the 1.27mm ffc cables, the total weight and volume of the cable is reduced by 70% compared to conventional round wire harness. The cable can also be increased by using the reinforcement material or liner method to obtain Additional mechanical stability.

When the circuit of the circuit is too complicated and the single layer board can not be routed or need copper foil for grounding shielding, you need to choose double or even multilayer fpc cable. Multilayer fpc cable have the holes connecting the layers of copper foil. This is a typical difference of single layer fpc cable .

Advantages and Disadvantages of Automotive FFC Cable

Automotive FFC cable including single-sided, double-sided and multi-layer board. The substrate based on polyimide CCL-based materials. Its advantage including high heat resistance, good dimensional stability, and good electrical insulation performance.

Automotive FFC cable shortcomings:

(1) high initial cost of a single time

Since the flexible PCB is designed and manufactured for special applications, the cost of the circuit design, wiring, and backplane is high.

(2) difficult changes and repair

Once the soft PCB is made, it must be changed from the bottom of the map or the preparation of the light painting program, so it is not easy to change its surface covered with a protective film, to be removed before repair, repair and then to restore, it is more difficult jobs.

(3) size is limited

It can not be done very long, very wide.

(4) can be damage easily when improper operation.

Improper operation of the installation can easy to cause damage to the soft circuit, the soldering and rework needs of trained personnel operation.

Advantages of automotive cable FFC cable:

(1) can be free to bend, winding, folding, according to the space layout requirements of any arrangement, and in any three-dimensional space to move and stretch, so as to achieve the integration of components and wire connections.

(2) the use of FPC can greatly reduce the size and weight of electronic products.

(3) FFC also has good heat dissipation and weldability as well as easy to install, the overall cost is low, the combination of soft and hard design to a certain extent make up for the flexible substrate in the component carrying capacity of a slight shortage.

The Function and Solution of Robot FFC Cable

The Function and Solution of Robot FFC Cable


Robot FFC cable is a simple structure flexible board. Usually the materials are substrate, transparent plastic, copper foil, protective film and transparent plastic. The foil is subjected to a process such as etching to obtain the desired circuit, and the protective film is to be drilled to expose the corresponding pads. After cleaning, combined by rolling and then plated at the exposed pad portion Gold or tin. General also stamping into the corresponding shape of the small circuit board. Now, many products used the cable, because the cable can be twists and turns, in the printer, mobile phones, notebooks and many other products.

The type of robot FFC cable:
1, single panel
The use of single-sided PI copper plate material in the line after the completion of a layer of protective film, forming a single-layer conductor only a flexible circuit board.
2, ordinary double panel
The use of double-sided PI board deposited copper material in the double-sided circuit is completed, the two sides were added with a protective film, as a double conductor with a circuit board.
3, the substrate to generate a single panel
The use of pure copper foil material in the circuit process, respectively, in the two sides of each layer plus a layer of protective film, as a single-layer conductor, but in the circuit board has a conductor on both sides of the exposed circuit board.
4, the substrate to generate double-sided
A double-sided conductor circuit board having a two-layer, one-sided PI-plated copper material material is bonded to each other at a specific position to form a double-sided conductor circuit board in a localized region, A circuit board with high flexural properties.

Darlox FFC Housings

According to the pitch, there are 1.27MM ffc housing, 2.54mm ffc housing, including single row, double rows, multi-rows.

Housing baffle

To ensure the firmly using with the terminal contacts which is with the contact barbs Any type of housing baffle can not be damaged and deformed, especially due to the wrong terminal or other reasons for secondary use.

Barbs groove

Channel of contact barbs. Generally can be directly from the appearance to identify the direction of interspersed. Some others that more subtle can also confirm the direction of the contact piercing from the direction of the housing baffle.

Adaptation conditions

1, the size of the contacts (high, width) and the caliber of the housing.

2, the location of the contact barbs and housing baffle.
3, interspersed process is smooth.
