Your Product.
Our Circuit.
Zero Compromise.
Stop losing months and margins to PCB/PCBA suppliers who don't speak your language -- technically or literally. FEILIZ is your end-to-end engineering partner in China, turning your home appliance and consumer electronics ideas into production-ready boards, fast.
Sound familiar? Missed deadlines. Surprise quality failures. Endless revision rounds. Hidden costs that kill your margin. We built FEILIZ to fix exactly that.
// THE PROBLEM WE SOLVE
Why Most Overseas Buyers
Struggle with PCB/PCBA
These aren't just inconveniences. They are margin killers and time bombs that derail product launches.
Communication Breakdown
Technical requirements lost in translation. Spec misunderstandings discovered only after tooling is cut -- costing weeks and thousands of dollars.
Quality Inconsistency
First samples pass, but mass production batches show alarming defect rates. No real QC process, just reactive firefighting after the fact.
Hidden Cost Escalation
Quoted price looks competitive until engineering changes, re-spins, and "unexpected" material surcharges erode your margin to zero.
Slow NPI Cycles
Your competitor launches while you're still waiting for prototype revision #7. Fragmented suppliers with no coordination mean every change ripples into delay.
No Engineering Support
Your supplier is a factory, not an engineer. DFM issues, signal integrity problems, and BOM optimization are left entirely to you -- or discovered in production.
Supply Chain Opacity
No visibility into sub-tier suppliers, component sourcing, or production status. You're flying blind until a shipment arrives -- or doesn't.
There is a better way.
FEILIZ was built specifically to eliminate these pain points -- with a resident engineering team, ISO-certified processes, and a single accountable partner from schematic to shipment.
// WHAT WE DO
Full-Spectrum PCB/PCBA
Development Capabilities
Every capability you need. One team. One factory. One point of contact.
PCB Hardware Design
Schematic capture, multi-layer PCB layout, signal integrity analysis, EMC pre-compliance, and thermal management -- handled by engineers with 15+ years in home appliances and consumer electronics.
- 1-20 layer boards
- High-speed, RF, power electronics
- IPC-2221 / IPC-7711 compliant
Firmware & Software Development
Embedded firmware, MCU/DSP programming, communication protocols (BLE, Wi-Fi, Zigbee, UART, I²C, SPI), and app-level software integration for smart home and IoT products.
- RTOS & bare-metal firmware
- OTA update architecture
- Multiple software copyrights held
DFM Analysis & Rapid Prototyping
We review your design for manufacturability before a single board is made. Catch layout errors, component availability issues, and assembly risks early -- saving you respins and weeks of delay.
- Free DFM review on first project
- 3-week NPI kickoff guarantee
- Small-batch prototypes from 10 pcs
SMT Assembly & PCBA Manufacturing
5 fully-automated high-speed SMT lines in our 10,000 m² Dongguan facility. AOI, X-ray, ICT, and functional testing at every production stage. Stable, experienced team -- not seasonal labor.
- 5× automated SMT lines
- AOI + X-ray + functional test
- Defect rate < 1/1,000 guaranteed
Structural & Mechanical Integration
Our structural engineers coordinate injection-molded plastic parts, metal stampings, and enclosures alongside PCB design -- eliminating the gap between electronics and mechanical teams that kills most projects.
- Injection molding coordination
- Metal stamping & hardware
- Enclosure & connector fit verification
Finished Product Assembly & Export
Beyond PCBA -- we handle final product assembly, aging/burn-in testing, packaging, and export logistics. Your finished goods, ready for your warehouse or direct to retail.

// WHY FEILIZ
The Partner Advantage:
What Sets Us Apart
15+ Year Engineers on Every Project
Unlike factories that hand you to a sales rep, your FEILIZ project is led by senior PCB engineers with 15+ years of domain experience in home appliances and consumer electronics. They catch design issues before they become production disasters.
ISO-Certified. Defect Rate < 1/1,000.
We're a nationally recognized high-tech enterprise with ISO 9001 and ISO 14001 certifications. We don't just claim quality -- we back it with standardized SOP processes, multi-stage inspection, and a contractual defect rate commitment that most factories won't dare make.
PCB Design → Assembly → Finished Product
Most "one-stop" suppliers outsource half the work. At FEILIZ, PCB design, firmware, structural coordination, SMT assembly, functional testing, and final product assembly are all managed internally. One point of contact. Zero coordination gaps. 30%+ faster project cycles.
VA/VE Analysis That Saves 20-40% on BOM
Our engineers don't just build your design -- they improve it. Through Value Analysis and Value Engineering (VA/VE), we identify over-specified components, suggest qualified alternatives, and optimize the BOM for the best cost-performance ratio. Average savings: 20-40% on unit cost.
// HOW IT WORKS
