Custom FPCB Engineering
Custom FPCB designed around your product and production process.
When a standard FPCB model cannot match your LED package, power target, cutting unit, board width, connection structure, or downstream process, NWSIRY helps turn the requirement into a confirmed circuit, a tested sample, and a production-ready solution.

From requirement to production
The drawing is confirmed before tooling and trial production begin.
When Standard Models Are Not Enough
Your product may need a circuit designed around the real assembly.
A model number can be a starting point. It is not always the right answer for a new LED Strip, LED panel, or sensor connection project.
LED and resistor layout
LED package, LED voltage, density, resistor quantity, resistor package, and pad position must work together.
Power and heat target
Copper thickness, current capacity, board width, heat dissipation, and the target wattage need to be considered as one system.
Cutting and connection structure
Cutting unit, solder pad length, connection spacing, and installation clearance affect both assembly and field use.
Downstream production fit
The circuit must be compatible with SMT, splitting, extrusion, encapsulation, potting, packaging, or sensor assembly.
A custom FPCB project should be confirmed on paper before it becomes a mold, a sample, and a production risk.
Engineering Review Before Drawing
We do not start with the mold. We start with the questions.
The engineering team reviews the customer's target and identifies several workable options before one proposal is confirmed.
Custom FPCB Development Process
Clear decisions before each production commitment.
The exact schedule depends on circuit complexity, material selection, customer feedback, and tooling requirements. The process below reflects a typical custom project path.
Step 01
Requirement review
Confirm the application, electrical target, board structure, production stage, and expected volume.
Step 02
Engineering drawing
Develop the circuit layout, LED and resistor arrangement, cutting unit, pads, and key dimensions.
Step 03
Option discussion
Explain the available design options and the trade-offs in performance, assembly, cost, and production fit.
Step 04
Drawing confirmation
Send the engineering proposal to the customer and confirm the final drawing before tooling.
Step 05
Tooling agreement
Confirm tooling scope, commercial terms, timing, and the conditions for trial production.
Step 06
Tooling and trial run
Produce the tooling and run the first material through the production process. A typical tooling reference is about 25 working days.
Step 07
Sample validation
Provide a typical 5-10 meter sample for customer testing, assembly validation, and performance feedback.
Step 08
Mass production
After the sample is approved, confirm the production specification and move into repeatable volume supply.
Typical Project Timing
Make the next milestone visible.
Use this as a planning reference. Final timing is confirmed after the drawing, tooling scope, materials, and sample requirements are reviewed.

These are typical project references, not a universal delivery promise. Complexity, feedback speed, materials, tooling, and production planning can change the schedule.
Beyond LED Strip Applications
One custom process, more than one application.
The same Roll-to-Roll engineering approach can support other long-length flexible circuit projects. These are application-led projects, not standard catalog models.
Application 01
LED Panel Connection FPCB
Flexible connection circuits for LED panel products where the circuit must follow the assembly structure and connection positions.
- Reduce traditional wire harness work
- Customize connection position and length
- Review fit with panel assembly and downstream production
Application 02
Smart Sensor Connection FPCB
Long-length flexible circuits for greenhouse and environmental monitoring systems, including distributed temperature and humidity sensing.
- Support sensor node and connection spacing design
- Suitable for continuous installation routes
- Project examples may reach approximately 100 m, subject to review
Start with the Product Requirement
Have a drawing, sample, or application that does not fit a standard model?
Send the target voltage, LED or sensor details, board dimensions, connection requirements, expected volume, and downstream process. NWSIRY will review the manufacturing fit with you.
