How Molex FFC has Revolutionized PCB Manufacture

1) Greater efficiency: 

The Molex FFC cable is a single, flat cable that may help connect several components on the same board. FFC eliminates the need for several wires and requires less wiring, which has increased the efficiency of PCB production. In turn, this minimizes the complexity of the production process and shortens the time needed to make printed circuit boards, resulting in cost savings for manufacturers.

2) Increased dependability:

This feature makes it excellent for applications where reliability is of the utmost importance, such as the automotive and aerospace sectors. In addition to being resistant to corrosion and oxidation, the FFC can operate in a broad temperature range. This feature has improved dependability, resulting in fewer market failures and recalls.

3. Reduced Weight

Molex FFC should be thin and lightweight, helping manufacturers to decrease the total weight of their PCBs. It is, therefore, crucial in applications where we have constrained space and weight, such as aerospace and medical devices. Additionally, the reduced weight of Molex FFC decreases shipping costs and makes PCBs easier to carry.

4) Increased flexibility:

This permits PCB manufacturers to integrate features and components that would not have been possible with standard wires. The flexibility of the FFC also contributes to the reduction of the PCB’s overall size, making it easier to fit into tight locations.

5. Cost Efficiency:

The price of Molex FFC is significantly less than that of conventional cables. This trait makes it a more economical option for PCB producers, as it cuts the entire cost of production. In addition, Molex FFC requires no specialist tools or equipment for installation, making installation easier and decreasing labor expenses.

Molex FFC Manufacturing Procedure

Full PCB Manufacturing

There are multiple steps in the Molex FFC production process:

Material preparation:

Preparation of materials: Preparing the materials that will help to create the FFC is the first step in the production process. This step involves finding and assembling the necessary raw materials, such as copper wire and insulation, as well as any other parts that you might need, including connectors or terminals.

Wire drawing: 

The raw copper wire is drawn through a succession of dies to decrease its diameter and enhance its tensile strength. Wire sketching is the practice in question.


You divide the wire into several smaller wires and twist together to create a single conductor. As a result, the wire becomes more flexible and easy to handle thanks to this technique.


To guard against electrical interference and physical damage, we apply an insulation layer to the stranded wire. Many other materials, including Teflon, polyurethane, and PVC, can help provide this insulation.


After insulating the wire, print it with identifying marks or other details, including the wire gauge or the manufacturer’s name.

Cutting and insulating the ends:

After cutting the insulated wire to the proper length, you remove the insulation from the ends to reveal the conductors.


Depending on how you use the exposed conductors in the FFC, you can terminate with connectors or other electrical parts.


You will need to test the PCB for functionality, ensure that it meets the standards required, and troubleshoot for any defects.

Drawbacks of Molex FFC

Besides the various advantages, Molex FFC cables have the following few cons:

  1. Due to their smaller size and excellent price, Molex FFC cables are more expensive than conventional ribbon cables.
  2. Because Molex FFC cables are less flexible than conventional ribbon cables, it may be challenging to route them in constrained places.
  3. Due to their smaller size and higher capacitance, Molex FFC cables are more susceptible to signal attenuation and interference.


Due to their numerous benefits, such as robust design, high-speed data transfer rates, cost-effectiveness, and versatility, Artist 3D’s Molex FFC cables are a popular option for various applications. They are suitable for numerous applications, from consumer electronics to industrial automation. However, due to the small number of manufacturers who make Molex FFCs, they are less commonly available than other flat cable connections.
