Partner with us to accelerate product development & scale production.

Since June 2001, Minkinzi Circuit Technology Co., Ltd. has pioneered professional PCB design services in Shenzhen's electronics manufacturing hub. Starting with a core team of 2 engineers specializing in high-frequency circuit design, we now deliver end-to-end solutions for industrial control, consumer electronics, and communication hardware.

To meet escalating customer demands in April 2008, Minkinzi introduced specialized quick-turn PCB prototype services. We focused on delivering custom, complex PCB solutions, primarily collaborating with top-tier R&D centers and universities, such as Northwestern Polytechnical University. By adopting outsourced PCB production, we ensured rapid turnaround, high-quality prototypes, and cost-effective support to accelerate innovation for research and development projects.

Founded in September 2009, we established our first PCB factory in Shenzhen, initially specializing in prototype manufacturing and high-complexity PCBs. Through AS9100 military certification compliance, we expanded our capabilities to deliver mission-critical PCBs for aerospace and defense applications.

Since March 2010, we have been ISO 13485 certified for medical device quality management and UL certified for product safety compliance. That same year, we launched specialized low-volume, high-mix SMT assembly services, leveraging our partner network to deliver end-to-end PCBA solutions for prototyping and small-batch production.

In April 2011, Minkinzi achieved dual certification for TS16949 (the international automotive quality management standard) and GJB9001B (China's military equipment quality management system), underscoring its commitment to excellence in manufacturing, rigorous quality control, and compliance with global industry benchmarks.

Established in August 2013, we launched our dedicated SMT and assembly plant in Dongguan, China's premier electronics manufacturing hub. Starting with 3 SMT lines, 2 assembly lines, and a team of 23 skilled employees, this facility specializes in high-precision PCBA, robotics integration, and end-to-end electronic production solutions.

In 2015, we significantly expanded our PCB manufacturing and PCBA assembly facilities to enhance production capabilities. Our SMT plant now operates with 11 advanced SMT lines and 5 dedicated assembly lines, supporting high-volume electronics manufacturing. The PCB factory spans 9,000 square meters, and our skilled workforce includes approximately 260 employees focused on delivering precision-engineered solutions for diverse industrial applications.

Expanding to Full Product Solutions: In 2017, CEO John Leng strategically invested in plastic injection molding and metal enclosure factories to meet growing customer demand for end-to-end manufacturing. This vertical integration empowered us to extend beyond core PCB Fabrication and PCBA Assembly services. We now deliver custom plastic/metal enclosures and comprehensive Box Build Assembly, providing complete turnkey product manufacturing from design to finished goods.

2018 Expansion: Elevating PCB & PCBA Manufacturing Capabilities Across China

In 2018, we strategically expanded our manufacturing footprint to meet growing global demand for high-quality printed circuit boards (PCBs) and printed circuit board assemblies (PCBAs). This expansion solidified our commitment to delivering scalable, reliable electronics manufacturing solutions, with investments in state-of-the-art facilities and advanced production technologies across key regions in China.

Hunan & Jiangxi PCB/PCBA Mega-Facilities

We significantly upgraded our existing PCB and PCBA production bases in Hunan and Jiangxi provinces, enhancing both capacity and operational efficiency:

• PCB Factory: Expanded to over 51,000 square meters across 4 floors, featuring cutting-edge manufacturing lines optimized for high-precision PCB production, from prototyping to mass production. This facility supports a wide range of PCB types, including rigid, flexible, and HDI (High-Density Interconnect) boards, catering to industries such as automotive, telecommunications, and consumer electronics.

• PCBA Factory: Expanded to over 16,000 square meters, equipped with advanced surface mount technology (SMT) and through-hole assembly lines. The facility integrates automated testing and quality control systems to ensure reliability and compliance with international standards (e.g., ISO 9001, IATF 16949).

Dongguan PCBA Branch: ZhiYi Electronics Co., Ltd. – A New Hub for Excellence

Complementing our regional expansion, we established a dedicated Dongguan PCBA Branch Factory – ZhiYi Electronics Co., Ltd. in 2018, strategically located in the heart of China’s electronics manufacturing hub to serve global clients with speed and precision. Key highlights include:

• Scale & Infrastructure: A standalone 5-story building with ~3,000 square meters per floor (total ~15,000 square meters), designed for lean manufacturing and seamless workflow integration.

• Production Capacity:Equipped with 12 SMT lines, 8 assembly lines, and 6 functional test lines, enabling high-volume PCBA production with quick turnaround times. The facility specializes in complex assemblies, including IoT devices, industrial controllers, and medical electronics.

• Talent & Quality Focus: Employing 320+ skilled professionals, with 2/3 dedicated to quality assurance (QA) and engineering roles. Our team of engineers(hardware, software, and process) and QA experts ensures rigorous testing,from component inspection to final product validation, minimizing defects and maximizing customer satisfaction.
