Uncompromising
Quality Standards
Every board leaving our factory is inspected, tested, and verified against the strictest industry standards. ISO9001, UL, and RoHS certified — with IPC Class 2/3 compliance and 100% AOI coverage across all SMT lines.
Quality Certifications
HUAXING holds globally recognized certifications across quality, safety, environmental, and automotive standards — audited regularly by SGS, UL, and other accredited bodies.
ISO 9001:2015
Quality Management System
Certified for PCB design, fabrication, assembly, and test services. Audited annually by SGS — covering all production stages from incoming materials to final shipment.
UL Certification
PCB Safety Standard
UL 796 recognized for PCB fabrication. Suitable for end products requiring UL component recognition and safety compliance.
RoHS & REACH
Hazardous Substance Compliance
All lead-free assembly lines are RoHS-compliant. Full material declaration reports available per board. Halide-free fluxes used across SMT lines.
IPC Class 2 / 3
Industry Standards Compliance
All production follows IPC-A-600, IPC-6012, IPC-A-610, and J-STD-001. Class 3 available for high-reliability applications.
ITAR Compliance
International Traffic in Arms
ITAR-compliant facility procedures for defense and aerospace projects. Secure handling of controlled technical data.
ISO 14001:2015
Environmental Management
EMS certified — waste management, lead-free processing, and environmental controls in place across the 45,000 m² facility.
Inspection Process Flow
Eight-stage quality system covering every step from incoming materials to outgoing shipment. Each board goes through at least three rigorous quality checks before delivery.
Incoming QC (IQC)
Raw PCBs and components inspected upon arrival. Bare boards undergo visual inspection, dimensional verification, and coupon testing. Components checked for date code, quantity, and solderability.
Solder Paste Inspection (SPI)
3D SPI (Koh Young) measures paste volume, area, height, and alignment on every board post-printing. Out-of-spec prints trigger automatic stencil cleaning and reprint. Reports available per panel.
Automated Optical Inspection (AOI)
Every board passes through 3D AOI (Omron / SAKI) after reflow — checking component presence, polarity, alignment, tombstoning, and solder joint quality. Defective boards flagged and routed to repair.
X-Ray Inspection
BGA, QFN, and other hidden-joint components inspected via Nordson DAGE digital X-ray. Void percentage, solder ball shape, and bridging analyzed per J-STD-001. Minimum 5 boards per batch sampled.
In-Circuit Testing (ICT)
Agilent i3070 fixtures test opens, shorts, resistor/capacitor values, diode orientation, and basic IC connectivity. Full pass/fail reports generated per board with traceable logging.
Functional Testing (FCT)
Custom test jigs simulate real-world operating conditions — power-on tests, signal integrity checks, firmware loading, and system-level validation. Test scripts developed with your engineering team.
Final Visual Inspection (FVI)
IPC-A-610 Class 2/3 visual criteria applied to every board before packing. Documentation includes inspection stamp, serial number (if requested), and digital photo archive for full traceability.
Outgoing QC (OQC)
Final verification of packaging, labeling, quantity, and documentation (CoC, test reports, shipping manifest). Lot acceptance sampling per ANSI/ASQ Z1.4 AQL standards.
Testing Capabilities
Comprehensive testing infrastructure covering every stage of production — from solder paste inspection through functional validation. Every board is tested, every joint verified.

Our Quality Commitment
Quality is not a department at HUAXING — it is embedded in every process, every machine, and every person on the factory floor. We believe in doing it right the first time.
3x Rigorous Quality Checks
Every product undergoes a minimum of three independent quality checks before shipment — inline AOI, electrical test, and final visual inspection.
Full Traceability
Every board is serialized and tracked through production. Digital photo archives, test reports, and material certificates accompany each shipment.
Continuous Improvement
Monthly quality reviews, corrective action tracking (8D/CAPA), and annual internal audits ensure our processes only get better over time.
Quality by the Numbers
Quality metrics audited quarterly. Full reports available upon request.
