What is Molex FPC?

Flexible printed circuit (FPC) cables made by Molex help connect electrical parts in various applications. This circuit is a polyimide, polyester, and other substrate materials-based thin, flexible circuit board. Molex FPCs provide a dependable and cost-effective way to connect electrical components in confined spaces.

Components of a Molex FPC

1. FPC housing:

The Molex FPC’s housing, which is the device’s outside casing, secures the other board components. It typically consists of plastic and is available in various dimensions and forms to suit the task. The FPC housing also shields the internal components from stress and vibration while offering a reliable seal for the cable. In the event of maintenance or repairs, it also makes interior components easily accessible.

2. FPC Connector:

The FPC connector is the connection point between the cable and the FPC enclosure. It is a two-piece assembly of a male and female connector that fits together tightly. Generally composed of high-grade plastic, the FPC connector creates a dependable connection between the cable and the FPC housing.

3. FPC Terminal:

The FPC terminal connects the FPC to the object it is powering. Engineers often construct the terminal from a high-grade material like brass, nickel, or stainless steel to ensure a reliable connection between the FPC housing and the device. Typically, the terminal is detachable for upkeep and repairs.

4. FPC Retainer Clip:

The FPC retainer clip is tiny and fastens the FPC housing to the apparatus. The clip typically consists of high-quality plastic and helps attach to the FPC housing and the device securely. The retainer clip aids in keeping the FPC housing stationary and free from movement or vibration while in use.

5. FPC Contact:

The FPC contact is the portion of the FPC that interfaces with the item it is powering. The contact usually consists of high-grade material, such as brass, nickel, or stainless steel, and it serves to establish a dependable connection between the FPC housing and the gadget. For maintenance and repairs, the contact is typically detachable.

6. FPC Shield:

The FPC shield is a thin metal plate that shields the FPC from vibration and stress. The shield comprises a high-grade material, usually steel or aluminum, and serves as a durable and secure barrier between the FPC and the outside world. Electrical shorts are also less likely as a result of the shield.

7. FPC Cable:

The flexible FPC cable serves as a connection between the FPC housing and the item it is powering. The cable provides a solid and reliable connection and consists of high-quality materials like Teflon, nylon, or PVC. In addition, the cable frequently includes a protective coating to shield it from harm and degeneration.

Manufacturing Process of Molex FPC

Full PCB Manufacturing

The manufacturing process of Molex FPC consists of two stages: the fabrication stage and the assembly stage.

1. Fabrication Stage

In the fabrication stage, the following are the steps followed:

  1. Design and Layout:

The design and layout of the FPC are the initial steps in the fabrication cycle. For the FPC, the design engineer produces a layout that specifies the suitable components, the trace geometry, and the general architecture of the board. The client reviews the layout and permits that.

  • Lamination:

After the layout approval, the FPC is ready for lamination. A thin coating of copper covers the flexible plastic substrate during this procedure. After that, high pressure and temperature help attach the copper layer to the plastic substrate.

  • Drilling:

This process involves preparing the FPC for drilling following the lamination procedure. Then, to prepare the board for the components to sit on, engineers must prepare the holes using a drill press.

  • Etching:

Engineers prepare the FPC for etching after the drilling operation. They remove the extra copper from the board using an acidic solution during this procedure.

  • Plating:

After the etching procedure, engineers prepare the FPC for plating. During this procedure, they apply a thin layer of metal to the board. The board will benefit from this layer of metal’s corrosion and other environmental protection.

  • Testing:

The FPC is now ready for testing. This procedure uses specialist testing equipment to ensure the board is operating correctly.

2. Assembly Stage

The assembly stage involves the following iterations:

  1. Insertion:

The insertion of components is the initial stage of the assembling process. Next, engineers place the components into the board using an automated machine.

  • Soldering:

Once engineers have installed the components, they prepare the FPC for soldering. In this procedure, they heat and solder the components to the board using a soldering iron.

  • Cleaning:

The FPC is ready for cleaning after the soldering procedure. Engineers will clean the board of any extra solder and debris during this procedure using a degreaser.

  • Inspection:

The FPC is now ready for inspection following the cleaning process. A microscope helps examine the board for flaws or irregularities during this procedure.

  • Packing:

The FPC is finally ready for packaging. This technique uses specific packing materials to prevent damage to the board during transportation and storage.
