Berlin has evolved from a historical administrative center into one of Europe's premier high-tech hubs. The region—anchored by the Berlin-Brandenburg metropolitan area—is experiencing a massive industrial renaissance. Driven by the transition toward Industry 4.0, the expansion of electromobility (exemplified by major Gigafactories in the region), and a thriving medical technology cluster, the demand for high-reliability Printed Circuit Board Assemblies (PCBA) has reached unprecedented levels.
For Berlin-based hardware startups, established mid-sized enterprises (Mittelstand), and multinational corporations, finding an EMS partner that bridges the gap between rapid prototyping and cost-effective, high-volume manufacturing is critical. STHL serves as this vital link. By combining Shenzhen's agile supply chain ecosystem with rigorous German quality standards, we deliver PCBA solutions that empower Berlin's innovators to scale globally.
Our manufacturing processes are aligned with the strict regulatory frameworks of the European Union, ensuring seamless integration into local supply chains while maintaining the competitive cost structures necessary for global market success.

Shenzhen STHL is a premier, high-quality provider of Electronics Manufacturing Services (EMS) in China. We serve customers worldwide along the entire 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 nearly two decades of experience in electronics contract assembly manufacturing. Currently, our team consists of over 220 highly skilled staff members. Our state-of-the-art 10,000 sqm facilities house 7 automated SMT assembly lines, 2 DIP/THT lines, 2 functional testing lines, and 2 finished device assembly lines.
We provide specialized electronics assembly services across diverse sectors, including energy power, communications, automotive, medical, consumer electronics, computers & storage, safety & security, and commercial/industrial products. Our global clientele spans Germany, the USA, Italy, the UK, Poland, New Zealand, Argentina, Brazil, Turkey, Korea, Thailand, and over 90 other regions worldwide.
Leveraging state-of-the-art machinery and engineering expertise to handle the most complex board designs.
We can handle a wide range of advanced components, ensuring precision and long-term reliability in harsh environments:
Our commitment to quality goes beyond component expertise. We utilize advanced inspection techniques, including inline Solder Paste Inspection (SPI), Automated Optical Inspection (AOI), and X-Ray inspection, to guarantee flawless assembly.
For critical applications in aerospace, medical, and automotive sectors within the Berlin market, STHL manufactures assemblies in strict accordance with IPC-A-610 Class III standards. This guarantees maximum continuous operation, long life cycle reliability, and resistance to extreme thermal and mechanical stress.
100% AOI Inspection + Sample 3D X-Ray + Custom Functional Testing (FCT) for every production batch.
STHL PCBA also excels in Through-Hole Technology (THT) assembly, which remains critical for high-power, high-stress industrial applications:
How our PCBA capabilities align with the specific technological demands of the German capital region.
With Berlin-Brandenburg becoming a central hub for electric vehicles and smart transit, we provide heavy-copper, high-reliability PCBAs for EV charging stations, battery management systems (BMS), and vehicle-to-grid (V2G) communication modules.
Supporting Berlin's smart city initiatives, we manufacture low-power, compact PCBAs integrated with RF modules (LoRaWAN, NB-IoT, 5G) for environmental sensors, smart metering, and municipal automation systems.
For the automation sector in Adlershof and Siemensstadt, we assemble ruggedized controller boards, industrial gateways, and sensor interfaces designed to operate reliably under high electromagnetic interference (EMI).
Working with an offshore manufacturer requires absolute trust, especially regarding intellectual property (IP) protection, customs clearance, and delivery schedules. STHL has optimized its global operations to provide Berlin clients with a hassle-free import experience.
Strict IP Protection: We implement rigorous data security protocols. All design files, schematics, and firmware are stored on secure, isolated servers. Non-Disclosure Agreements (NDAs) governed by international and German commercial laws are standard practice before any project files are shared.
Logistics & Customs (DDP Shipping): We offer flexible shipping terms, including Delivered Duty Paid (DDP) via air freight or express couriers (DHL/FedEx). This means STHL handles all customs clearance, import declarations, and EU import duties, delivering the finished PCBAs directly to your facility in Berlin without administrative delays.
Component Obsolescence Management: Our global sourcing network actively monitors component lifecycles. If a specified part is near end-of-life (EOL), our engineering team proposes drop-in replacements or redesign suggestions to prevent production halts.
From initial design review to final box-build assembly, we manage the entire lifecycle of your electronic products.
STHL operates 7 automated PCB assembly lines for both prototype and mass production. Advanced SMT ensures precise component placement and quality. Skilled technicians provide efficient THT assembly and RoHS-compliant lead-free soldering.
STHL PCB fabrication service produces high-quality, reliable printed circuit boards from simple singles to complex multi-layers, from flex PCB to rigid-flex PCB. We use premium materials and controlled processes to meet precise specifications.
STHL offers global electronic component sourcing and supply chain solutions. Our vast supplier network and expertise ensure access to genuine, certified parts, mitigating risks of counterfeits, allocation, and long lead times to secure your production schedule.
With the precision manufacturing of cable assembly components including handles, retention systems, connectors, and shielding in a wide range of materials and finishes, we have performed many successful cable assemblies for customers from various industrial applications.
Making your projects at STHL from SMT assembly to box build assembly is very cost-effective and fast to market. Covering everything from putting a PCBA into the enclosure with all functions testing to a complete product assembly packaged and ready for delivery, we supply full support.
STHL conducts functional testing (FCT) to verify product performance, preventing defects such as circuit issues, missing or incorrect components. This ensures delivered products are stable and fully qualified before leaving our factory.
Investing in next-generation manufacturing technologies to support the future of hardware innovation.
As electronic devices become smaller, faster, and more integrated, the demands on PCBA manufacturing escalate. STHL is continuously updating its technical roadmap to align with these trends:
Expanding our capabilities in microvia drilling, sequential build-up (SBU), and fine-line lithography to support complex multi-layer designs required for 5G and high-speed computing.
Integrating machine learning algorithms into our AOI and SPI systems to predict solder joint anomalies and optimize thermal profiles in real-time, reducing defect rates to near-zero.
