Shenzhen STHL is a high-quality provider of electronics manufacturing services (EMS) in China, serving customers worldwide along the whole industry chain including PCB layout, components sourcing, PCB fabrication, PCBA assembly, cable assembly, box build assembly, and comprehensive testing services.
Established in 2006, STHL brings 20 years of experience in electronics contract assembly manufacturing. Currently, our team consists of over 220 dedicated staff members. Our 10,000 sqm state-of-the-art facilities house 7 SMT assembly lines, 2 DIP/THT lines, 2 function testing lines, and 2 finished device assembly lines.
We provide electronics assembly services for energy power, communications, automotive, medical, consumer electronics, computers & storage, safety & security, commercial, and industrial products. Our customers span the globe, including the USA, Germany, Italy, UK, Poland, New Zealand, Argentina, Brazil, Turkey, Korea, Thailand, and over 90 other regions, with a rapidly growing footprint in the Nigerian industrial sector.
As an IATF16949, ISO9001, ISO14001, and ISO13485 certified electronics assembly manufacturer, we produce products that comply strictly with RoHS standards. Our advanced equipment and reliability testing (AOI, X-RAY, ICT, and functional tests) ensure we are recognized as a long-term, reliable PCBA vendor worldwide.
Nigeria is experiencing an unprecedented industrial transformation. As Africa's largest economy, the nation is aggressively modernizing its infrastructure, driven by key initiatives in telecommunications expansion, off-grid renewable energy, and smart utility metering. The demand for robust, high-performance Printed Circuit Board Assemblies (PCBAs) has skyrocketed as local assembly plants and technology developers seek to build localized solutions.
In the power sector, Nigeria's push for solar mini-grids and smart prepaid meters (under the National Mass Metering Programme) requires PCBAs that can withstand severe voltage fluctuations, high ambient temperatures, and dust. Similarly, the rapid expansion of 4G/5G networks by major telecom operators demands high-frequency, multi-layer communication boards that ensure uninterrupted data transmission. STHL bridges the gap by providing Nigerian enterprises with tier-1 manufacturing capabilities, mitigating the risks of component failure in harsh operating environments.
Custom PCBAs designed for smart prepaid meters, solar charge controllers, and power inverters optimized for Nigeria's unique grid conditions.
High-frequency, multi-layer RF boards supporting GSM, 4G LTE, and emerging 5G deployments across West Africa.
Reliable DVR and IP camera PCBAs tailored for urban security monitoring in major metropolitan hubs like Lagos, Abuja, and Port Harcourt.
Our surface mount technology (SMT) lines are equipped with high-speed, high-precision pick-and-place machines capable of handling the most complex component geometries. We specialize in:
For power electronics, heavy-duty industrial controllers, and connectors that require high mechanical strength, THT remains indispensable. STHL's THT capabilities include:
From initial design validation to final box build, we manage the entire lifecycle of your electronic products.
Operating 7 automated SMT lines and dedicated DIP lines, we handle prototype runs to high-volume mass production with equal precision.
From simple single-sided boards to complex multi-layer rigid, flexible, and rigid-flex PCBs using premium, high-TG base materials.
Global supply chain network ensuring access to genuine, certified components. We mitigate counterfeit risks and manage lead times effectively.
Custom wire harness and cable assembly manufacturing, utilizing diverse connectors, shielding, and jacket materials for industrial applications.
Full system integration, including enclosure assembly, routing, front panel installation, and final packaging for ready-to-market products.
Comprehensive testing protocols (FCT, ICT, burn-in) to verify complete system functionality before shipment to Nigeria.
The next decade of electronics in West Africa will be defined by edge computing, IoT integration, and localized manufacturing. As Nigeria moves towards smart city initiatives, the demand for intelligent edge devices—such as smart traffic systems, localized agricultural sensors, and automated grid switches—will surge. STHL is aligning its technical roadmap to support these developments by investing in High-Density Interconnect (HDI) PCB fabrication, embedded component technologies, and advanced conformal coating processes that protect electronics from high humidity and saline environments typical of coastal regions like Lagos.
Furthermore, we are expanding our Design for Manufacturing (DFM) support to help Nigerian hardware startups and established enterprises optimize their layouts for cost-effective mass production. By bridging the gap between local design and global manufacturing standards, we aim to accelerate the time-to-market for innovative African hardware solutions.
Engineered for diverse industries, from telecommunications and renewable energy to aerospace and consumer electronics.

Everything you need to know about partnering with STHL for the Nigerian market.
Yes, we regularly ship to Nigeria (including Lagos, Abuja, and Port Harcourt) via reliable international air and sea freight forwarders. We handle all export documentation and can coordinate with your local clearing agents to ensure smooth customs clearance.
We offer advanced conformal coating services (acrylic, polyurethane, or silicone) to protect the assembled PCBs from humidity, dust, and corrosion. Additionally, we use high-TG laminates and lead-free solder alloys that maintain mechanical and electrical integrity under high ambient temperatures.
Absolutely. STHL has an established global supply chain network and direct partnerships with authorized distributors (such as Arrow, Avnet, Digi-Key, and Mouser). We provide full traceability for all sourced components to guarantee authenticity and performance.
Our manufacturing facilities are certified under IATF16949 (Automotive Quality Management), ISO9001 (Quality Management), ISO14001 (Environmental Management), and ISO13485 (Medical Devices Quality Management). All products can be manufactured to comply with RoHS and REACH standards.
We support our clients through all stages of growth. We have no strict MOQ; we accept low-volume prototype runs (1-10 pcs) for testing and validation, as well as high-volume mass production runs exceeding 100,000 units.
We work closely with your engineering team to implement custom testing rigs and software flashing protocols. Our testing capabilities include In-Circuit Testing (ICT), functional testing (FCT), boundary scan, and temperature burn-in testing to ensure 100% functionality before dispatch.
