About Us
We are a full-cycle service and product provider in the electronics industry. Our mission is resource integration and shared value creation. Fifteen years ago, we started with electronic component trading and gradually expanded our capabilities to include PCB manufacturing, SMT assembly, design, mechanical processing, and harness production — forming a closed-loop "Design — Procurement — Manufacturing — Assembly — Testing — Delivery" cycle.
Competition in the electronics industry has shifted from comparing technical specifications to a comprehensive battle for efficiency: cost control and delivery speed. We understand that our clients face not a single problem, but systemic challenges across the entire product lifecycle: from component selection and cost estimation at the design stage, to multi-line-item small-batch procurement, supplier coordination, and quality consistency assurance. Every stage can become a bottleneck.
To address these challenges, we have built a full-cycle service system. Design: 20+ engineers embed manufacturing constraints at the PCB layout stage, ensuring design for manufacturability. Procurement: a global supply chain of 5,000+ brands, with an AI-powered BOM engine for cost optimization and cross-reference matching. Manufacturing: deep integration with 500+ audited factories in the Pearl River Delta and Yangtze River Delta, enabling flexible capacity management. Delivery: a dedicated project manager oversees quality and timelines.
Cost: centralized procurement and digital matching reduce BOM costs by 15–30%. Economies of scale allow small-batch clients to access large-volume pricing. Quality: every PCBA board undergoes five inspection stages — SPI → AOI → X-Ray → ICT → FCT. Acceptance to IPC-A-610 Class 3, first-pass yield of 99.7%+. Delivery: flexible warehousing plus FedEx/DHL/UPS — 7–15 days to major markets.
Our core competency is deep supply chain immersion. Every partner factory goes through four selection stages: equipment specification verification — confirming technical capability alignment; on-site audit — assessing management, personnel qualifications, and capacity utilization; quality system audit — process documentation, inspection procedures, defect traceability; compliance verification — ISO, IATF certifications, and export licensing. Only after all four stages is a factory added to our approved supplier registry.
Today, we unite a supply chain of 5,000+ component brands and collaborate deeply with 500+ audited factories in the Pearl River Delta and Yangtze River Delta. Over 15 years, we have completed 5,000+ projects for 300+ corporate clients. Our customers operate in automotive electronics (Continental, Bosch, BYD), industrial automation (Siemens, ABB, Schneider), consumer electronics (Huawei, DJI, Xiaomi), medical devices (Medtronic), semiconductors (Intel, TI), and other industries.
We firmly believe that the value of a service is measured by the market success of the client's project. Every completed project is a testament to our mutual growth. Whether it is a startup's first prototype or an annual contract from a global corporation — we deliver with the same professionalism and quality standards. We are ready to become your long-term partner in electronics contract manufacturing.

Testimonials
Real testimonials from clients worldwide
"qisourcing built a complete production cycle for us — from sourcing scarce ICs to volume SMT assembly. Monthly output grew from 400 to 8,000 controllers."
Technical Director · Moscow, Industrial Automation
"As a PCB distributor in Germany, I was skeptical about sourcing from Asia. qisourcing not only delivered flawless quality but gave us the documentation package our aerospace clients demand."
Managing Director · Stuttgart, PCB Trading
"We struggled for three years with intermediaries supplying remarked chips. qisourcing gave us a transparent supply chain with full batch traceability."
CEO · St. Petersburg, Electronics Distribution
"Our BOM cost dropped 45% without sacrificing a single spec. The AI-driven alternative component analysis was something our 8-person startup could never have done on its own."
CEO & Co-Founder · Austin, TX — IoT Hardware Startup
"Moving from three vendors blaming each other to a single partner managing everything was a turning point. SMT first-pass yield went from 84% to 98.5%."
COO · Milan, Industrial Automation
"In 48 hours, qisourcing found the two Xilinx FPGAs our team had been searching for over two weeks. Thanks to them, we saved a €1.8 million contract with SNCF."
Technical Director · Lyon, Electronic Equipment
