Flexible PCB Manufacturing Process

The complete flexible PCB manufacturing process is based on the design package that makes the circuit board in physical form. Following is the process of flexible PCB which starts with design and ends with testing:

Step 1: Pre Production Engineering

According to the manufacturing data and requirements provided by the customer, our engineers will compare it with standards and capabilities to make sure compliance and conduct related checks.

Step 2: Photo Plotting

A laser photo-plotter can be used to plot a film for each individual layer. A laser photo-plotter is a tool used to create photo-tools for solder mask and silkscreen.

Step 3: Imaging and Develop or Etch

This process applies the primary images such as pads and traces onto the circuit board. Here is what to do in this step: Apply photo imageable to the copper panels. Furthermore, image the panels using LSI. Etch off the whole exposed copper from the panel. Strip the remaining Dry Film and just leave the remaining copper pattern for the inner layers.

Step 4: Automated Optical Inspection

AOI basically inspects different layers of flexible PCB before laminating all layers together. The optics compare the PCB design data to the actual image on the panel.

Step 5: Oxide

Oxide is a chemical treatment to inner layers before lamination for flexible PCBs. It is an important step to increase the roughness of copper to enhance the laminate bond strength.

Step 6: Lamination

To produce a flexible PCB, different layers of epoxy-infused fiberglass are laminated together. The presser and heat cause the fiberglass sheet to melt and tightly join the layers together.

Step 7:Drilling

All PCBs need some holes to link copper layers, attaching components and mounting the PCB. We can drill holes using some advanced drilling systems. Furthermore, these have a design for the fast removal of chips in abrasive materials.

Step 8: Electroless Copper Deposition

After drilling, manufacturers deposit a thin coat of copper on the exposed surfaces of the panels chemically. Furthermore, they deposit a copper coat on the hole walls using electroless plating.

Step 9: Dry Film Outer Layer

After copper deposition, you must apply the outer layer images to prepare the panel for electroplate. So we can utilize a laminator machine to coat outer layers with the dry film. The dry film is a photo imageable material.

Step: 10 Plate

The electroplating process involves copper plating onto the conductive pattern. Plus on the hole walls of the PCB as well. The thickness of the plating is around 1 mil. After copper plating, you need to deposit a thin layer of tin plating.

Step 11: Striping and Etching

After completing the plating process on the panel, the dry film remains. Then, removing the uncovered area of copper by tin. So traces and the pads around the holes and copper patterns remain there. At last, remove the remaining tin that is covering holes and traces chemically.

Step 12: Surface Finish

It is the last and final chemical process to manufacture a multilayer printed circuit board. Solder mask covers almost all circuitry. So the surface finish prevents oxidation of the remaining exposed copper area.

What is flexible PCB

Flexible printed circuit board (PCB), as the name suggests, is a very flexible circuit board. It is a special type of circuit board that can be bent into the desired application shape. In contrast to ordinary rigid circuit boards, this type of circuit board places conductive paths and electrical components on a flexible substrate made of polyimide or polyester film.

What’s the type of flexible PCB

Single sided PCB is the lowest cost, simplest flexible board, only one side has a conductive layer, generally used in consumer electronics products with low electrical performance requirements and single-sided wiring.

The middle of the double sided PCB is an insulating layer, and there is a layer of chemically etched conductive patterns on each side, and the pattern conductive paths on both sides are connected through metal holes to realize signal transmission.

Multilayer PCB is a multi-layer single-sided or double-sided flexible board laminated together, drilled and metallized, and conductive paths between different layers.

Rigid-flex board laminates rigid and flexible boards together, and has the characteristics of rigid and flexible boards at the same time, flexible boards can be bent, hard boards carry heavy devices, optimize internal space, improve product performance, suitable for miniaturization, intelligence and highly integrated development.

What's the application of flexible PCB

In the 5G era, multi-function modules for smartphones appear, and RF modules, folding screens, and miniaturized models are inseparable from the connection of FPC flexible circuit boards

High-speed digital/RF/microwave connectors
High-frequency applications require consistent thin-film circuit layers to be better applied, so various types of flexible polymer films have become indispensable materials in the development of PCB circuit boards. Flexible PCBs made of these materials are the best choice for high-frequency applications.

Medical equipment
Flexible electronic technology has very important applications in the biomedical field, and now non-invasive blood glucose measurement, photoelectric blood oxygen sensor, 3D spiral wound electrode based on climbing bionics, sciatic nerve signal acquisition, skin-like flexible deformation sensor, carbon nanofiber foam flexible pressure sensor, skin-like flexible pressure sensor and other flexible medical electronic products.

What are the advantages and disadvantages of flexible PCB

● Advantages of flexible PCBs
Save space and weight.

Flexible printed circuit boards. Notice how it takes up less space when folded or rolled up.

Improved stability and reliability

Eliminates the need for connectors and harnesses and minimizes wiring errors

They can be stacked in various configurations

High tensile strength and high resistance to radiation, chemicals and temperature extremes

Durable (suitable for harsh environments)
Higher heat dissipation performance than other dielectric materials
There is no need for solder joints and connectors to test flex circuits, which further reduces assembly costs

Easy to install

Provides strong signal quality

Improved impedance control

● Disadvantages of flexible PCBs
It has a higher cost compared to rigid PCBs in specific applications

It uses a complex assembly process

Difficult to repair or rework

Proper storage conditions are required

Improper handling is easy to damage

What are the materials used in flexible PCB

The metal used in this layer is usually copper because of its excellent electrical properties and low cost. Heat dissipation is also a key factor to consider, and copper can do this quickly.

Other suitable conductor materials include stainless steel, beryllium copper, and cupronickel.

A glue layer containing acrylic or epoxy resin is located between the copper and the insulating film (polyimide). Acrylic adhesive materials offer better heat resistance but have poor electrical properties and lower bond strength.

On the other hand, epoxy resin is not the best heat resistant, but it has better electrical properties and viscosity.

An insulator, also known as a substrate or dielectric, is a flexible material that gives the bending properties of that circuit board. Polyimide is the most commonly used material, but some sheets are available in polyester, polyetherimide, various copolymers or fluoropolymers.

Flexible PCB Prototype

PCB proofing, also known as PCB prototyping, is like a test board for testing purposes. During the PCB design process, you may need to change a lot of things and come up with different designs and dozens of changes. Until the test results are available after PCB proofing, you never know if your PCB is suitable for mass production and if you need to add components to make changes. Therefore, you need proofing to validate your design.

Flexible PCB design

To successfully design flexible PCBs, it is important for designers to have a basic understanding of flexible design requirements.

Prerequisites for resilient design

Number of layers, finished board thickness, PCB material use, surface finish, drill bit size, drill copper
Dimensional drawings must define rigid to flexible interfaces

Flexible PCB stack structure and layer sequence

Stacking distinguishes between rigid and flexible layers in the PCB. The flexible PCB stacking diagram will give the thickness of each layer, including the copper weight of the conductive layer. It will also indicate the impedance curve and impedance value (50 ohms or 100 ohms).

Explanatory notes for PCB manufacturers

Flexible copper clad laminate, overlay material, maximum board thickness, minimum size for plated through-holes, electrical test requirements, cover color, silkscreen color, circuit board markings such as part number, version and company logo, packaging and shipping needs

Flexibility and bending radius
The flexibility of a flexible PCB depends on the bending radius of the flexible material used. The bend radius is the smallest angle at which a bendable area can be bent. Knowing the number of flex PCB bends is critical to your design. If the PCB bends more times than the design allows, the copper will begin to stretch and crack.

Dimensional stability
Flexible PCBs exposed to various processes, including etching, plating, pressure, temperature, and chemistry, are prone to small dimensional changes, so this is something designers must consider.


Shielding is another important parameter to consider in flex circuits. Implement various methods to incorporate masking. The shield is used to limit the effects of EMI and ESD. The shield also helps to keep the control impedance requirements constant. Designers typically perform four types of shielding, including copper cladding, copper shadowing, silver paste/epoxy, EMI thermoplastic shielding film.

Flexible PCB assembly

Fix the FPC precisely on the carrier board

The shorter the storage time between the FPC being fixed on the carrier board and the time it is printed, mounted, and soldered, the better.

Solder paste printing for FPC

FPC does not have special requirements for the composition of solder paste, but FPC has high requirements for the printing performance of solder paste. The solder paste should have excellent thixotropy, be easy to print and demold, and firmly adhere to the FPC surface, and there will be no bad demolding to block the stencil leakage hole or collapse after printing.

There is an optical MARK mark for positioning on the FPC, so SMD placement on FPC is not much different from mounting on PCB. According to the characteristics of the product, the number of components and the placement efficiency, medium and high-speed placement machines can be used for mounting.

Reflow soldering
A forced hot air convection infrared reflow soldering furnace is used, so that the temperature on the FPC can change more uniformly and reduce the generation of poor welding.

Inspection, testing and sub-boarding
The removed FPC is placed under a magnifying glass of more than 5 times for visual inspection, focusing on checking the surface residue, discoloration, gold finger staining, tin beads, IC pin empty soldering, continuous welding and other problems. FPC completes ICT and FCT testing with the help of special test fixtures.

How to calculate a flexible PCB cost?

Generally, PCB prices are affected by the following factors:

1. Delivery cycle

2. Quantity

3. Number of PCB layers

4. Manufacturing process

5. PCB material

6. Project cost

In the future, flexible circuit boards should continue to develop in the following four aspects:

1. Strengthen bendability: bendability is the biggest advantage of flexible board, in the future flexible board should be actively innovated in the use of substrate, bending resistance should be stronger, more flexible and convenient to use.

2. Cost reduction: the cost of flexible board is high, rarely used except for special needs, if the price is reduced, the application market will expand.

3. Upgrade the manufacturing process: After the flexible board is made, the change and repair are more troublesome, and the production size is subject to certain restrictions, so the manufacturing process level should be upgraded to meet higher requirements.

4. Reduce thickness: light and thin is a major feature of flexible board, now the rigid board is more and more sophisticated, flexible board to maintain this advantage, in the thickness must be thinner.


As the foundation of electronic products, flexible circuit boards have broad development space, especially with the advancement of science and technology, new energy vehicle industry, intelligent products and other industries have flourished, so that the market demand for flexible boards has further expanded. In the future, we will strengthen technological innovation, increase research and development efforts, and improve product reliability and safety.
