What is the Cost of Flexible PCBs?

On average, flexible PCBs can range from $0.50 to $5.00 per square inch for standard designs and materials. However, this cost is not fixed and can vary based on several factors. The factors that influence the price include necessary assembly labor, prevailing labor rates, and the time required for assembly. Additionally, overhead manufacturing expenses and the design complexity of the board play significant roles in determining the final cost.

Factors Affecting Flex & Rigid-Flex PCB Cost 

Many criteria determine the cost of FPCBs, and we have highlighted the major ones below;

  • Physical Size; A large FPCB means a higher price, and its calculation is a cost per square inch (FPCB measurement).
  • Circuit Construction; It depends on the materials used and the number of layers and pads. An additional layer is costly, and quality materials plus more pads also increase manufacturing costs.
  • Volume; a greater volume results in a high cost.
  • Layers; Added circuit layers augment assembly costs; thus, if you’re comfortable with a single-sided FPCB, stick with it.
  • Finishing; Almost always, a good finishing guarantees a long shelf life for FPCB. Therefore, it’ll be pricey.
  • Number and size of holes; Since drilling small holes is tough, FPCB prices are higher. Not only that but more holes equal more cost.
  • Flex Board types depend on layers, ultimately determining the price.
  • Custom or unique specification; If you require added features on your FPCB, for instance, solder mask clearance, side plating, or contoured edges, you’ll pay extra.

How to Reduce PCB Production Cost?

Every manufacturer should have a flex PCB cost estimator list that helps lower FPCB costs.

  • Keep flexible layers to a minimum; Usually, rigid laminates are more cost-effective than flexible laminates. You’ll lower the cost by reducing the number of layers in the flexible circuitry.
  • Keep overall layers to a minimum; If you reduce the number of layers, the number of plies of flow prepreg you’ll need will also be low. Thus, the cost decreases.
  • Limit controlled impedance requirements; incorporating all achievable impedance values might be tempting. However, if you consider the design’s cost-effectiveness, test and model the values your flex circuit board needs.
  • The copper thickness can be flexible and about 1/3 oz.
  • Finally, buy FPCBs in large quantities to lower the overall cost.

Types of Flex & Rigid-Flex PCBs

Flex and rigid-flex PCBs come in a diverse range of configurations, from simple single-layer flex to complex multilayer rigid-flex designs, each offering unique advantages for different applications. 

PCB TypeDescription
Single-layer FlexOne conductive layer on a flexible substrate. Simple, cost-effective for basic applications.
Double-layer FlexTwo conductive layers with a flexible substrate in between. Allows for more complex circuits while maintaining flexibility.
Multilayer FlexThree or more conductive layers. Offers high circuit density in a flexible format.
Rigid-Flex (Basic)Combination of rigid and flexible board sections. Typically 2-4 layers total.
Rigid-Flex (Advanced)Complex designs with multiple rigid and flex layers. Can have 6+ layers.
HDI FlexHigh-Density Interconnect flex circuits. Uses microvias for increased circuit density.
HDI Rigid-FlexCombines HDI technology with rigid-flex structure for maximum density and functionality.
Sculptured FlexVarying copper thickness in different areas of the circuit. Allows for both flexibility and robust connections.
Dynamic FlexDesigned for repeated flexing or rolling. Used in applications with constant movement.
Flex with StiffenersFlexible circuits with rigid areas added for component mounting or structural support.
Bookbinder Rigid-FlexRigid boards connected by flexible sections, allowing the assembly to fold like a book.
Rigid-Flex with CavitiesIncorporates hollowed-out areas in rigid sections for 3D component placement.
Flex on BoardFlexible circuit attached to a rigid board, often used for interconnections or as a connector.
Flex with Embedded ComponentsIncorporates components within the layers of the flexible circuit.
Stretchable Flex

Uses specialized materials to create circuits that can stretch as well as bend.

How are Flex & Rigid-Flex PCBs Manufactured?

How are Flexible PCBs Manufactured
Flexible PCBs Manufacturing Process

Flexible PCBs’ manufacturing involves several steps to form thin and flexible boards which are easy to bend, fold and shape. Here are the steps that complete the PCB manufacturing process.

Step 1: Fabricate flexible laminates by bonding copper to PI film

Step 2: Laminate coverlay and copper foil

Step 3: Drill holes for vias and through holes

Step 4: Electroplate holes to form conductive vias

Step 5: Image and develop photoresist for circuit pattern 

Step 6: Etch away unwanted copper

Step 7: Strip photoresist and apply solder mask over bare copper

Step 8: Expose and develop a solder mask

Step 9: Cure solder mask and apply surface finish 

Step 10: Punch or route PCB to final shape

Step 11: Print silkscreen legends and conduct electrical tests

Step 12: Singulation and packaging
