At TOPFAST, we are continually improving how engineers and purchasing teams communicate with our manufacturing and engineering departments.
To streamline the inquiry process for flexible circuit projects, we have officially launched a dedicated Flexible PCB Inquiry page.
This submission page is designed specifically for customers working on flexible PCB and rigid-flex PCB applications, enabling our engineering team to review project requirements more efficiently.

Why We Created a Dedicated Flexible PCB Inquiry Page
Flexible PCB projects often involve requirements that differ significantly from standard rigid PCB manufacturing.
Typical considerations include:
- Dynamic bending requirements
- Static flex applications
- Polyimide materials
- Coverlay specifications
- Stiffener requirements
- Rigid-flex transitions
- Assembly considerations
Because of these unique requirements, flexible PCB projects usually require more detailed engineering review before production can begin.
The new inquiry page allows customers to submit project information in a format specifically tailored for flexible circuit manufacturing.

Benefits of the New Inquiry Process
Faster Engineering Assessment
Project information is routed directly to the appropriate engineering team for review.
Improved Technical Communication
Flexible PCB requirements can be communicated more clearly from the beginning of the project.
Better Manufacturing Evaluation
Our engineers can review material selection, bending areas, and special process requirements before quotation.
Reduced Project Delays
Early identification of manufacturing considerations helps reduce design revisions later in the process.

Typical Applications for Flexible PCB Technology
Flexible circuits continue to play an important role in modern electronic products.
Common applications include:
Medical Devices
Flexible circuits are widely used in compact diagnostic and monitoring equipment.
Consumer Electronics
Smartphones, wearable devices, and portable electronics often utilize flex PCB technology.
Automotive Electronics
Flexible circuits support advanced driver assistance systems, displays, sensors, and control modules.
Industrial Equipment
Flex PCBs enable reliable connections in space-constrained industrial systems.

Engineering Support for Flexible PCB Manufacturing
Every flexible PCB project presents unique engineering challenges.
Our engineering review process may include:
- Material recommendations
- Stackup evaluation
- Bend radius assessment
- Stiffener recommendations
- Manufacturability review
- DFM analysis
This helps ensure that designs are optimized before manufacturing begins.
