What is Flexible PCB?

Flex PCBs, also known as flexible printed circuit boards, are designed to fit the electronic device or product, allowing for a more customizable circuitry layout. This is different from traditional circuit boards where the device must conform to the circuit board. One of the defining features of Flex PCBs is the unique pattern and arrangement of printed circuitry and components, made possible by the malleable base material.

What are the available structures for flexible circuit boards?

Various structures are readily accessible, with the more prevalent ones outlined below:

Double sided flex (IPC-6013 type 2) The product features a bonded coverlay on both sides of an adhesiveless double-sided FPC core, featuring two conductive layers and plated through holes. Optional stiffeners can be included.

Single sided flex (IPC-6013 type 1) Coverlay, which is made of polyimide and adhesive, is bonded onto an adhesiveless single sided FPC core. This can be done with or without the use of stiffeners.

Multilayer flex (IPC-6013 type 3) This product features a Coverlay that is bonded to both sides of an adhesiveless construction. It includes at least three conductive layers and plated through holes. It is also available with or without a stiffener, making it a versatile option. This version has a 4-layer capability.

Our company specializes in producing flexible and rigid-flex PCBs, ranging from prototypes to small batch production. Feel free to browse through examples of our manufactured flexible PCBs.

Advanced Manufacturing Technology

While traditional subtractive manufacturing is still widely used in the PCB industry, Bgpcba has taken into account the varying demands of its customers and has expanded its capabilities to encompass the use of additive and semi-additive manufacturing technologies for producing flexible FPC boards.

By selectively removing excess copper foil from the surface, the subtractive process generates the desired circuit pattern on the copper-clad laminate. This well-established and dependable traditional method provides cost benefits, making it a top choice for numerous manufacturers and customers.

The process of additive manufacturing includes electroplating the circuit pattern onto the substrate when there is no previous pattern. This technique is especially advantageous for creating high-density flex PCB. However, it should be noted that additive manufacturing is still considered a less mature method and may lead to increased project expenses, resulting in its less frequent use.

Our semi-additive method is designed to overcome the limitations of traditional additive manufacturing methods. By using a combination of UV-cured film and electroplating technology, we can precisely increase the thickness of the copper on the circuit according to the customer’s specifications. Additionally, our technique allows for greater flexibility in controlling copper thickness, independent of line width. With this approach, we are capable of producing flexible PCB boards with a minimum line width and spacing of 14μm/14μm and a minimum aperture of 55μm.

Details Processing

While being able to produce an FPC board does not automatically guarantee top-notch quality, at Bgpcba, we place a high emphasis on meticulous attention to detail, from providing exceptional service to implementing quality control measures and special protocols, all in order to deliver superior results.

Our services cover everything from initial design to delivering top-notch, customizable PCBA boards right to your door. We have expertise in both traditional SMT and THT assembly methods, as well as flip chip technology, which allows for direct chip-to-substrate connections through inversion.

In addition, we understand the significance of minor processing in preserving the ideal state of flexible circuit PCBs. AtBgpcba, we provide an extensive selection of surface treatment choices beyond immersion gold, immersion tin, and immersion silver. Our surface treatment services feature HASL, lead-free HASL, gold plating, and others.

With our attention to detail and commitment to excellence, we guarantee superior product performance.


Flexible printed circuit boards offer a number of potential benefits including:

  • Saving Space. The design of Flex PCB allows for 90% space and weight savings compared to traditional circuit board assemblies, giving more freedom in installation and packaging. Additionally, its unique flexibility allows for tighter bending capabilities.
  • Maximum Reliability. A flexible PCB board minimizes the need for interconnects, contact crimps, connectors, and solder joints, resulting in decreased risk of failure and increased reliability. This is due to the fact that the board has fewer potential sources for failure compared to traditional rigid boards. As a result, it is a more secure and reliable option.
  • Enhanced Capabilities.These circuits boards are highly versatile, working well with a wide range of connectors and components, including ZIP connectors. They are also known for their exceptional performance in extreme temperatures and their strong resistance to radiation and chemicals.
  • Cost Savings. Flexible PCBs offer various cost-saving advantages, including decreased material and packaging requirements, reduced expenses for parts replacement, and prevention of assembly errors that may result in the need for repairs.

-Flex PCBs offer a variety of benefits that make them well-suited for various industries such as Military, Transportation, Medical, Consumer Electronics, Automotive, Aerospace, Communications, and Industrial.

Why Not Make All Circuit Boards Flexible?

While flexible circuit boards have their value, they cannot completely replace rigid circuit boards for every purpose. Cost-effectiveness remains a challenge in utilizing an entirely flexible circuit board layout for a consumer product. With lower manufacturing costs and easier installation in automated facilities, rigid circuit boards still offer an advantage.

The most effective solution for a cutting-edge product typically incorporates flexible circuitry when needed and utilizes sturdy, dependable rigid circuit boards where feasible to minimize production and assembly expenses.

Hybrid rigid-flex printed circuit boards are often preferred by manufacturers for specific applications, such as in laptop computers and medical devices. This is due to the ability to connect rigid boards using flexible circuits. By utilizing the strengths of each technology, these boards can be customized to meet a variety of engineering requirements.

Flexible Printed Circuit Fabrication

Two primary methods are available for creating a flexible printed circuit: Subtractive and additive processes.

The circuitry pattern is defined through the subtractive process, which involves removing unwanted areas of metal from a solid metal surface using either screen printing or photo imaging. These methods, screen printing and photo imaging, are the two most prevalent ways of creating the circuitry pattern in use today.

The circuit is created by adding metallic traces to a bare dielectric layer through the manufacturing process. The conductive layer is applied using printing, plating, or deposition methods, providing reliable and efficient results.

While the subtractive process is a popular choice for its durability and budget-friendly nature, it offers more freedom in the final product design. On the other hand, the additive process yields circuits with lower current-carrying capabilities and less resistance to environmental factors than subtractive processes.

Flexible Printed Circuit Finishing and Assembly

To properly prepare the flexible printed circuit surface for additional bonding methods like SMT assembly, wire bonding, or pressure connector insertion, surface finishing is often required. Nickel, gold, tin, silver, and solder are among the recommended metals for this purpose. Alternatively, organic coatings can also be utilized to protect the copper until the bonding process, which will dissolve the material.

Flexible printed circuits can attach various electronic and mechanical devices, as well as bond to curved surfaces and be shaped in any 3D form. When constructed correctly, these circuits can handle dynamic flexing, making them ideal for connecting electronic components in packages with moving or rotating parts.
