Prototype
to Millions.
You've validated your concept. Now comes the hard part -- scaling without breaking quality, budget, or timeline. FEILIZ acts as your engineering extension in Shenzhen & Dongguan, guiding your PCB/PCBA from first sample to mass production with zero guesswork.
// THE SCALE-UP GAP
Why Most Prototypes
Never Make It.
The jump from a working prototype to a manufacturable, cost-efficient product is where most hardware startups stall -- or fail entirely.
Endless Delays
Tooling revisions, BOM errors, and supplier miscommunications push your launch date back by months.
Hidden Cost Traps
Unit costs balloon at scale because the design was never optimized for manufacturability from the start.
Quality Inconsistency
Samples look great. Production batches don't. Without rigorous QC processes, defect rates spike at volume.
Communication Walls
Language gaps, time zones, and opaque factory processes leave you guessing about your own product's status.
FEILIZ Closes the Gap.
We embed our engineering team into your project from day one -- handling DFM, tooling coordination, supplier management, and QC -- so you scale with confidence, not crossed fingers.

The FEILIZ Scale-Up Process
Requirements Review
Share your specs, drawings, or existing prototype. We assess feasibility and identify risks within 3 days.
DFM Analysis
Our engineers run a full Design for Manufacturability audit -- flagging issues before tooling costs are committed.
Prototype & Validate
Rapid sample builds with full functional testing and aging verification. Iterate fast, validate thoroughly.
Pilot Production
Small-batch run to validate SOP, line efficiency, and QC checkpoints before full-scale commitment.
Mass Production
Seamless ramp-up on our 5 SMT lines. Ongoing QC, progress reports, and on-time export delivery.
Not Just a Factory.
