Tailored electronics assembly services engineered to meet the stringent quality standards of the Kansai industrial region.
Osaka and the wider Kansai region have long been the beating heart of Japan's heavy industry, precision machinery, and consumer electronics. Today, this region is undergoing a massive digital transformation. The demand for highly reliable Printed Circuit Board Assemblies (PCBA) has shifted from traditional consumer electronics to advanced industrial automation, IoT-enabled medical devices, smart energy grids, and next-generation automotive systems.
Local enterprises in Higashiosaka, Sakai, and Yodogawa require manufacturing partners who understand the meticulous quality standards of the Japanese market—specifically zero-defect tolerances, long-term product lifecycles, and robust environmental compliance (RoHS & REACH).
Established in 2006, Shenzhen STHL is a premier Electronics Manufacturing Services (EMS) provider. With nearly two decades of contract manufacturing expertise, we support global clients across the entire product lifecycle—from PCB layout and component sourcing to PCB fabrication, SMT/THT assembly, box build, and rigorous functional testing.
Our state-of-the-art 10,000 sqm facility houses over 220 skilled professionals and operates:
We are fully certified under IATF16949 (Automotive), ISO9001, ISO14001, and ISO13485 (Medical Devices), ensuring that every assembly leaving our floor meets the highest global benchmarks of quality and environmental safety.

Shenzhen offers immediate access to millions of active electronic components, reducing sourcing lead times from months to days. This allows Osaka-based R&D teams to prototype and iterate at unprecedented speeds.
At STHL, we implement rigorous testing methodologies including 3D Automated Optical Inspection (AOI), X-Ray inspection for BGA/QFN packages, In-Circuit Testing (ICT), and custom functional testing to guarantee 100% yield rates.
By leveraging economies of scale and highly optimized automated production lines, we offer Osaka businesses a highly competitive cost structure without compromising on component authenticity or build quality.
Modern electronics demand high component density and absolute thermal stability. STHL's engineering team is highly proficient in handling complex board geometries and advanced packaging technologies:
We specialize in high-precision placement of Ball Grid Arrays (BGA), micro-BGA (uBGA), QFN, QFP, and ultra-fine pitch components down to 01005 sizes. Our Package-on-Package (PoP) capabilities support advanced processing units for smart IoT devices.
For high-power applications, industrial power supplies, and automotive systems that experience high mechanical stress, our THT assembly services utilize both automated insertion and skilled manual soldering. All processes adhere strictly to lead-free, RoHS-compliant standards with dedicated ESD-safe environments.
From initial design schematic review to final packaged product delivery, we handle every step.
Operating 7 automated SMT lines and 2 DIP lines, we handle both rapid prototyping and high-volume production runs with equal precision.
From standard double-sided boards to complex multi-layer rigid, flexible, and rigid-flex PCBs using premium base laminates.
Global procurement network ensuring 100% original, traceable components from authorized distributors, mitigating counterfeit risks.
Custom wire harness and cable assemblies designed to withstand harsh industrial environments and high-vibration applications.
Full system integration including PCBA installation, enclosure assembly, cabling, and final packaging for direct-to-market shipment.
Custom testing jig development to simulate real-world operating conditions, ensuring zero-defect shipments to Osaka.
