Spain is undergoing a rapid technological evolution. Driven by national frameworks like the Plan de Recuperación, Transformación y Resiliencia (Recovery, Transformation, and Resilience Plan) and targeted PERTE investments in microelectronics and semiconductors, the demand for highly reliable Printed Circuit Board Assemblies (PCBA) has surged. Historically recognized for agricultural export and tourism, Spain is now a powerhouse for automotive engineering (the 2nd largest car manufacturer in Europe), clean energy development, and industrial IoT (IIoT).
At STHL, we address this transformation head-on. Our engineering teams design and manufacture PCBA ecosystems specifically for Spain’s critical growth sectors. Whether you are scaling an EV charging network in Barcelona, installing smart grids in Madrid, or developing advanced aerospace tracking modules in Seville, our ISO-certified facilities bridge the gap between initial prototyping and scalable mass production.
Combining 20 years of manufacturing experience with robust global supply chain execution to deliver end-to-end electronics manufacturing services (EMS).
Shenzhen STHL is a premium provider of electronics manufacturing services (EMS) in China, serving customers worldwide along the whole industry chain including PCB layout, component sourcing, PCB fabrication, PCBA assembly, cable assembly, box build assembly, and comprehensive testing services. Established in 2006, our 220+ dedicated professionals operate from our 10,000 sqm facilities. We run 7 SMT assembly lines, 2 DIP/THT lines, 2 function testing lines, and 2 finished device assembly lines.
Our customers span the globe, including key industrial innovators in Spain, Germany, the USA, Italy, the UK, Poland, and more. As an IATF16949, ISO9001, ISO14001, and ISO13485 certified electronics manufacturer, we ensure every assembly project strictly complies with the RoHS standard and features an absolute quality guarantee. We leverage advanced reliability testing (AOI, X-RAY, ICT, and FCT) to guarantee zero-defect delivery.
Our surface mount technology lines are optimized for high-density, complex, and mixed-technology assemblies. We handle components that require absolute precision:
For applications requiring heavy mechanical load, high voltage, or rugged physical connections—such as Spain's wind power grids and rail control systems—our THT assembly processes guarantee mechanical strength and electrical longevity:
End-to-end support from bare board prototyping to finished box-build systems ready for European retail shelves.
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 assembly for many 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 to your customers, we can supply the 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.
Ensuring your electronic goods strictly comply with local European laws and transit networks safely.
To sell or deploy hardware in Spain and across the European Union, products must meet strict regulatory thresholds. At STHL, compliance is built directly into our manufacturing pipeline. We utilize lead-free chemical alloys and trace component origins to meet the demands of:
Navigating customs and supply routes between manufacturing hubs in Shenzhen and major cities in Spain (Madrid, Barcelona, Bilbao, Valencia) requires reliable transport structures. We offer flexible shipping modes to match your budget and timelines:
