If you're a merchant looking for a high-quality PCB manufacturing partner, you should consider FPC. The product will undoubtedly revolutionize the way we interact with electronics in the years to come.

The FPC is a thin insulating polymer film on which a pattern of conductive circuits is printed, usually providing a thin polymer coating to protect the circuit. PCBS with cylindrical or rectangular shapes can be changed in size according to their application requirements.

Flexible PCB FPCS can be divided into two categories: rigid and flexible PCB. Rigid FPCS help to mechanically connect components, but cannot be bent. Flexible FPC is a double-sided PCB that can withstand bending forces. FPCS are popular among engineers because they are easy to modify and customize without any solder joints. The flexibility of the FPC allows for different retrofit solutions. It greatly reduces the cost of building new boards for specific applications.

The composition of an FPC material depends on its intended application and end use. The flexibility of FPC depends on the material’s ability to resist cracking, warping and mechanical damage while maintaining high electrical conductivity. Therefore, manufacturers tend to use fiberglass or FR-4 materials for FPC flexible printed circuit boards. It consists of a mixture of epoxy resin and fiberglass. FR-4 is a rigid board that combines thermal and electrical properties.

1. Insulating film

It is a layer of high-density polyethylene made by extruding the resin through a nozzle and coating it on the substrate. HDPE films eliminate capacitive coupling between substrates. It also eliminates other circuits to electrically shield the interconnects on top of the board. The HDPE layer also acts as a vapor barrier to prevent moisture from entering the circuit during curing.

2. Electrostatic adhesive layer

After the HDPE film is applied, the adhesive layer can connect the components. These components may include potentiometers and LEDs on the circuit board to improve performance or reduce cost. The adhesive layer is acrylic or polyimide, allowing the LED to be directly bonded to the FPC, saving material and assembly time.

3. Conductor

Then we add a conductive layer on top of the adhesive layer. This layer can be polyimide or epoxy or the printed circuit board itself. To avoid warping, we can apply the conductor to a solution at 100 °C.

4. Stiffener

Finally, we added a second adhesive layer to the conductors to further reduce bending or cracking issues. We usually use cellulose or acrylic for this layer.

To make an FPC board, components are first pre-assembled onto the board and then cut to size. The FPC material is then put into the mold to bend without breaking. Typically, we heat the FPC material to 120 °C for about 1 hour. This is done to obtain the necessary stiffness so that the material is able to resist the flexors and flex easily. The component is then added to the mold and pressurized to embed it in the FPC.

Next, we apply a layer of conductive ink on top of the component. It helps create a smooth surface that prevents electrical resistance and improves performance.

5. Overlay

The cover layer is a top plate made of polyimide or acrylic. The overlay protects the underside of the FPC material. It also acts as an insulation, preventing moisture from entering the FPC material. The overlay is also high-temperature resistant, allowing us to use it in ovens and heaters.

FPC has many applications in many different fields. We use FPCs in solar cells, cell phones, vehicles, and airplanes. Many of these applications require thin and durable flexible sheets. Therefore, they can withstand bending, folding, or rolling.

1. Hybrid Electronics

These are electronic product that has both organic and inorganic components. Hybrid electronics are useful clothing or building materials with embedded electronics.

2. Wearable Electronics

Wearable electronics include everything from fitness trackers to glasses and other products we wear on our bodies. We have been using FPC for wearable electronics.
