Explore our premium printed circuit board assemblies engineered for advanced commercial, medical, and industrial electronics.
Since our establishment in 2006, Shenzhen STHL has grown into a world-class Electronic Manufacturing Services (EMS) provider. From our advanced facilities in China, we deliver high-yield electronics manufacturing, helping partners cross the chasm from concept validation to global supply chain scale. We operate with structural compliance across IATF16949, ISO9001, ISO14001, and ISO13485 standards.
How China's manufacturing ecosystems act as the engine room for the next industrial revolution: EV, IoT, AI, and Medical electronics.
The PCB and PCBA landscape is undergoing massive technological shifts. The explosion of electric vehicles (EVs) has triggered unprecedented demand for robust power-electronics assemblies, high-current busbars, and complex Battery Management Systems (BMS). Simultaneously, the miniaturization of consumer devices and the stringent reliability expectations of medical hardware have pushed manufacturing standards past consumer levels. High-density interconnects (HDI), fine-pitch BGA arrays, and multi-layer rigid-flex boards are no longer outliers; they represent the new industry benchmark.
As a global hub, China (Shenzhen) offers unmatched advantages. From an optimized component sourcing network to specialized raw material suppliers and top-tier engineering talent, companies sourcing from Shenzhen enjoy highly compressed production timelines. However, the differentiator lies in QA protocols. High-performance electronics require specialized assembly factories like STHL that strictly follow IATF16949 (Automotive) and ISO13485 (Medical) standards to mitigate thermal fatigue, copper delamination, and component mismatch risks.
Surface Mount Technology (SMT) is the backbone of micro-electronics. Our production floor operates advanced Pick-and-Place machinery capable of mounting complex components with tight pitch spacing, ensuring mechanical resilience and optimal thermal paths.
For connectors, heavy inductors, power switch modules, and high-vibration applications, Through-Hole Technology (THT) remains indispensable. STHL combines automated insertion with skilled manual craftsmanship to construct highly durable mechanical joints.
A full turnkey solution from bill-of-materials (BOM) optimization to functional testing and complete mechanical enclosure assembly.
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-flexPCB, we use premium materials and controlled processes to meet precise specifications.
STHL offer 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 PCBAinto 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.
