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. To get a more accurate cost estimate, please use our free quote form.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.
Flexible & Rigid-Flex PCB Lead Times Overview
| Service Type | Lead Time |
|---|---|
| Standard PCB Manufacturing | 5-6 days |
| Expedited Manufacturing | 24-48 hours |
| PCB Prototyping (Quick Turn) | 1-2 layers: 5 days |
| 4 layers: 6 days | |
| 6 layers: 7 days | |
| 8 layers: 8 days | |
| 10 layers: 9 days | |
| PCB Assembly | 4-25 days, depending on complexity and order volume |
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 Type | Description |
|---|---|
| Single-layer Flex | One conductive layer on a flexible substrate. Simple, cost-effective for basic applications. |
| Double-layer Flex | Two conductive layers with a flexible substrate in between. Allows for more complex circuits while maintaining flexibility. |
| Multilayer Flex | Three 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 Flex | High-Density Interconnect flex circuits. Uses microvias for increased circuit density. |
| HDI Rigid-Flex | Combines HDI technology with rigid-flex structure for maximum density and functionality. |
| Sculptured Flex | Varying copper thickness in different areas of the circuit. Allows for both flexibility and robust connections. |
| Dynamic Flex | Designed for repeated flexing or rolling. Used in applications with constant movement. |
| Flex with Stiffeners | Flexible circuits with rigid areas added for component mounting or structural support. |
| Bookbinder Rigid-Flex | Rigid boards connected by flexible sections, allowing the assembly to fold like a book. |
| Rigid-Flex with Cavities | Incorporates hollowed-out areas in rigid sections for 3D component placement. |
| Flex on Board | Flexible circuit attached to a rigid board, often used for interconnections or as a connector. |
| Flex with Embedded Components | Incorporates 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?
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

It was easy to order online from OurPCB with instant price quoting. I had a recent bad experience with another international PCB fabricator that has changed owners and the quality had dropped, in this case the PCB boards I received were nearly flawless. I'm not sure if it's standard but I personally got my boards back in a week. Price competitive with other international fabricators. The detailed report provided along with the boards is also very useful. Recommended.
