PCB Manufacturing Process







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.

- Physical Size: Larger PCBs cost more, calculated per square inch.
- Circuit Construction: Costs depend on materials, layers, and pads. Extra layers or high-quality materials increase costs.
- Volume: Higher volumes result in higher costs.
- Layers: More layers mean higher assembly costs. Opt for single-sided FPCBs if possible.
- Finishing: Premium finishes guarantee longevity but come at a higher price.
- Holes: More or smaller holes drive up costs due to increased drilling complexity.
- Flex Board Types: Layer count influences price significantly.
- Custom Features: Specifications like solder mask clearance, side plating, or contoured edges add to the cost.
- Minimize flexible layers, as rigid laminates are more cost-effective.
- Reduce overall layers to lower the need for additional materials.
- Limit controlled impedance requirements to necessary values only.
- Opt for flexible copper thickness, approximately 1/3 oz.
- Purchase FPCBs in bulk to reduce unit cost.

Flex PCB Manufacturer FAQs
What are Flexible PCBs?
Flexible PCBs can be bent, shaped, wrapped, or folded into any 2D or 3D shape. These features make flexible PCBs perfect for use in medical and surgical equipment, consumer electronics, automotive and space applications, and smart wearable devices.
What is the minimum order quantity for Flex & Rigid-Flex PCB manufacturing?
We have no minimum order quantity, allowing you to order anything from single prototypes to mass production runs.
What services do you offer besides Flexible PCB production?
Beyond manufacturing, we also provide full EMS: What is it? solutions – short for Electronics Manufacturing Services. That means we can take a project from the initial design concept, source every part you need, handle assembly and testing, and even package the finished boards so they’re ready to ship. For many clients, this “one-stop” approach is faster, more cost-effective, and removes the hassle of juggling multiple suppliers.
Can you produce HDI flexible PCBs?
Absolutely. Our team works with High Density Interconnect PCBs for designs that require more circuitry in less space. With finer traces, microvias, and multiple build-up layers, HDI is often the right choice for rigid-flex PCBs in demanding fields like aerospace navigation, compact medical devices, and next-generation consumer electronics.
What’s the process for making Flex & Rigid-Flex PCBs?
The overall flow follows the same core steps you’ll find in PCB Manufacturing Process Explained, but with important adjustments for flexible substrates like polyimide. For instance, we use different lamination techniques to maintain bendability, and our etching process is fine-tuned to protect thin copper layers from damage. Every stage is planned to balance flexibility with electrical reliability.
How do you ensure the right components are used?
Before anything goes into production, our engineers and sourcing team go through a careful Identify Electronic Components process. We check each part against the project’s electrical, thermal, and mechanical requirements, and we confirm compatibility with the intended assembly method – something that’s especially important with flexible circuits.
Do you design for electrical safety?
We do. For example, in portable or sensitive electronics, overcurrent protection can make the difference between a safe shutdown and a burned-out circuit. In these cases, we’ll often recommend the use of the right Understanding Fast-Blow Fuses to provide rapid protection without impacting normal performance.
Why should I choose OurPCB for flexible PCB manufacturing?
In short – experience and consistency. As a Reliable PCB Manufacturer, we’ve built long-term partnerships by delivering quality boards on schedule, communicating openly, and meeting industry certifications year after year. Many of our customers have been with us for over a decade.
How do you prevent common assembly defects in flex PCBs?
One example is Troubleshooting Tombstoning in PCBs – a frustrating soldering defect where small passive components lift on one side during reflow. We address this through careful pad design, precise solder paste application, and temperature-controlled reflow profiles tailored to the flex board’s material properties.
Can flexible PCBs be used in small DIY projects like timers?
Absolutely. Flexible PCBs are not just for industrial or aerospace applications — they’re perfect for compact, custom electronics as well. For example, our guide on Creating a 10 Minute Timer shows how even a simple timing circuit can benefit from a flex PCB layout, allowing it to fit into tight spaces while maintaining durability and performance.
