Frequently Asked Questions
How long does proofing take for single-sided flexible circuit boards?
Flexible boards and general-purpose circuit boards typically take 1-3 days. Simple single-sided and double-sided layout soft boards have a proofing cycle of 1-3 days.
Do you provide free circuit board samples?
Yes, for orders with MOQ of 500pcs or more, we provide free samples including 10 extra pieces for regular delivery.
What layer count can you sample for flexible circuit boards?
We can produce circuit boards with 1-10 layers. Our integrated SMT factory enables complete patch assembly in one stop.
What is your typical sample completion time?
Depending on complexity, we can deliver flex board samples within 48-72 hours.
Is proofing done in-house?
Yes, as the original factory in Shenzhen, we provide complete FPC design, prototyping and mass production services.
How is proofing cost calculated?
Cost depends on layer count, copper thickness, size, surface treatment and other technical parameters.
Flexible PCB Technology Overview
Flexible printed circuit boards (FPC) offer significant advantages over rigid PCBs, including the ability to bend, wind, fold, and conform to three-dimensional space requirements. This makes them ideal for high-density, compact applications in aerospace, military, mobile communications, and consumer electronics.
Key Advantages
- Replaces multiple rigid boards and connectors
- Ideal for dynamic or high-flex applications
- Enables complex stacked configurations
- Reduces product size and weight
Considerations
- Higher cost compared to rigid PCBs
- Increased handling sensitivity
- More complex assembly process
- Limited repairability
Material Selection Guide
Polyimide is the preferred substrate material for most high-performance flexible circuit applications due to its:
- Superior flexibility and durability
- Excellent thermal stability (up to 260°C)
- Low dielectric constant for signal integrity
- Chemical and environmental resistance
- Dimensional stability
Note: While polyimide offers outstanding performance, it comes at a higher cost and requires careful handling during fabrication.
