Adhering to IPC-A-610 Class 3 standards for critical industrial and medical applications.
From initial design verification to full-scale box-build assembly, we provide end-to-end solutions.
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 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 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.
Analyzing the strategic advantages of combining German design rigor with Chinese manufacturing agility.
Shenzhen is the global epicenter of electronics component sourcing. We secure hard-to-find components, alternative parts, and raw laminates in a fraction of the time required in Europe, preventing production bottlenecks.
From rapid NPI (New Product Introduction) prototypes to high-volume production runs, our 7 SMT lines and 2 DIP lines offer flexible scheduling, allowing German SMEs to scale without heavy capital investment.
We operate under strict international standards: IATF 16949 for automotive electronics, ISO 13485 for medical devices, and ISO 9001/14001 for general industrial applications, matching German quality expectations.
How STHL supports German industrial sectors with specialized high-reliability PCBA services.
With Germany leading the transition to electric mobility, our IATF 16949 certified facility produces robust Electronic Control Units (ECUs), battery management systems (BMS), and charging station control boards. We ensure high vibration resistance, thermal management, and zero-defect soldering for safety-critical automotive applications.
