Built to
Deliver.
From PCB/PCBA engineering to full-product assembly -- our in-house capabilities eliminate the complexity, cost, and risk of managing multiple suppliers across China.
// 01 -- ENGINEERING TEAM & EXPERTISE
The Engineers
Behind Your Product
Common Pain Point
"Our Chinese supplier just builds what we send -- they never flag design issues, and we end up with costly rework after tooling is cut."
FEILIZ's in-house engineering team acts as your engineering extension -- proactively identifying DFM issues, optimizing BOM costs, and de-risking your product before a single component is ordered.

Experience
Launch Time
PCB / PCBA Design
Full schematic capture, PCB layout, multi-layer design, and firmware development for home appliance and consumer electronics applications.
- Schematic & Layout
- Firmware & Software Dev
- Multi-layer High-density
DFM Analysis
We review your design before production begins -- catching issues that would otherwise surface as expensive ECOs, scrap, or delayed shipments.
- Pre-production Review
- ECO Risk Reduction
- Written DFM Report
Structural Engineering
Dedicated structural engineers bridge the gap between electronics and enclosures -- ensuring PCB fitment, thermal management, and mold compatibility from day one.
- Enclosure Integration
- Thermal Management
- Mold Compatibility
VA/VE Cost Engineering
Our engineers analyze your BOM line by line -- identifying over-specified components, alternative materials, and process optimizations that cut unit cost without cutting performance.
- BOM Audit & Optimization
- Avg. 20-40% Cost Reduction
- Performance Maintained
IE & Process Engineering
Industrial engineers optimize assembly line layout, cycle times, and yield rates -- translating directly to faster delivery and lower labor cost per unit for your orders.
- Line Efficiency Optimization
- Yield Rate Improvement
- Cycle Time Reduction
Cross-Cultural PM
Our trade director brings 16 years of international experience -- bridging language, time zones, and cultural gaps so you always have clear, reliable project visibility.
- English-fluent PM
- Regular Progress Reports
- Export Compliance

// 02 -- ONE-STOP MANUFACTURING
One Partner.
Zero Gaps.
Common Pain Point
"We're managing 5 different suppliers in China -- PCB house, PCBA assembler, mold shop, plastic factory, final assembly. Every handoff is a risk of delay, quality drop, or finger-pointing."
FEILIZ consolidates your entire supply chain under one roof. One contact, one timeline, one accountability. We manage every handoff internally -- and you save 30%+ in project time as a result.

Injection Molding & Metal Parts
In-house coordination of plastic injection molds and metal stamping -- eliminating the structural-to-electronics integration gap.
Finished Product Assembly
Full box-build assembly combining PCBA, structural components, cables, and packaging into a market-ready product.
Testing & Burn-in
Functional testing, aging/burn-in facilities, and custom test fixture development to guarantee field reliability.
Export & Logistics Coordination
Compliance documentation, export licensing, freight coordination, and customs support for all major markets.
// 03 -- QUALITY & CERTIFICATIONS
Quality That
Ships on Time.
Common Pain Point
"We've had batches fail at customs inspection, products returned by customers for reliability issues, and suppliers who pass audits but fail in production. We can't afford that risk."
FEILIZ is a National High-Tech Enterprise with ISO-certified quality systems and a proven track record supplying major appliance brands. Our QC is embedded in every process stage -- not bolted on at the end.

Our Quality Control Process
Incoming QC
All incoming components inspected against spec before entering production
Solder Paste
Automated solder paste inspection before component placement
AOI Inspection
Automated optical inspection post-reflow to catch placement and solder defects
Functional Test
100% functional testing with custom test fixtures per product specification
Outgoing QC
Final AQL sampling and cosmetic inspection before packaging and shipment
Dedicated burn-in facilities stress-test products under elevated temperature and load conditions -- catching early failures before they reach your customers.
Every production line follows documented SOPs with visual work instructions -- eliminating operator variability and ensuring batch-to-batch consistency across all orders.
Complete batch traceability from component lot numbers to finished product shipment -- enabling rapid root-cause analysis and field issue resolution.
// 04 -- PRODUCTION FACILITIES
Built for
Scale & Speed.
Common Pain Point
"We've been burned by suppliers who looked great on paper but couldn't handle volume ramp-up. We need to know the factory can actually deliver at scale -- without quality dropping."
Our Dongguan facility is purpose-built for electronics manufacturing at scale -- with the automation, capacity, and stable workforce to support your growth from 500-unit pilots to million-unit mass production runs.
