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 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 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.
How STHL leverages smart manufacturing to deliver quality, stability, and speed to global markets.
The electronics manufacturing landscapes demand unmatched agility and flawless yield rates. As a premier China-based PCBA factory, STHL integrates the principles of Industry 4.0 to redefine the economics and reliability of SMT and THT assembly. By bridging smart automation, data-driven systems, and our physical footprint in Shenzhen, we optimize every segment of the design-to-delivery lifecycle.
Our digital supply chain leverages close partnerships with certified distributors, direct component manufacturers, and logistics networks. This ensures that even during global chip shortages, we maintain access to raw parts without compromising trace integrity or introducing counterfeit parts.
At STHL, precision is driven by real-time intelligence and automated monitoring systems:
From complex industrial controllers to safety-critical aerospace and automotive systems, STHL meets the stringent demands of global industry verticals.
Compliant with IATF 16949 standards, we design and assemble high-reliability assemblies for motor controllers, ADAS autopilot modules, and battery management systems (BMS).
Adhering to ISO 13485 regulations, our PCB assemblies support operating room monitors, ward diagnostics, and patient safety tracking equipment requiring zero-failure operations.
We build robust PCBA controllers for solar power, smart grids, EV chargers, and photovoltaic monitor networks, ensuring thermal efficiency and environmental longevity.
From robotic PLCs to explosion-proof monitoring controls, our robust assemblies are designed to withstand high temperature, vibration, and EMI fields.
Pioneering advanced manufacturing capabilities to power tomorrow's electronic systems.
Optimizing high-density placement processes and micro-reflow profiles to deliver thermal management and pixel-level dimming uniformity.
Scaling up production capabilities for complex rigid-flex layouts, ideal for smart wearables, aerospace navigation, and high-frequency communication units.
Advancing mounting precision for micro-BGA (0.3mm pitch) and vertically stacked component packages to accommodate IoT and edge AI computing demands.
Our research and development efforts are focused on the integration of artificial intelligence and continuous improvement workflows. By utilizing computer-aided DFM (Design for Manufacturability) analysis, we help customers debug layout faults before tooling begins, reducing revision counts and lowering overall time-to-market.
Furthermore, we are expanding our environmental green footprint. By transitioning to fully lead-free processes, adopting VOC-free cleaning solutions, and implementing digital waste reduction tracking systems, STHL aligns with RoHS and REACH standards.
Technical answers regarding our PCB assembly tolerances, quality inspection protocols, and material procurement pipelines.
We support a broad component package library, ranging from 01005 micro-chips to large BGA/uBGA (ultra-fine ball grid arrays) down to 0.3mm pitch. Our high-speed placement systems have a placement accuracy of +/- 0.035mm, verified with 3D Solder Paste Inspection (SPI) and Automated Optical Inspection (AOI) units at crucial inline stages.
We work exclusively with authorized global distributors (e.g., Arrow, Avnet, DigiKey, Mouser) and direct component manufacturers. For client-consigned BOMs, we implement a strict incoming material inspection (IQC) containing visual testing, package verification, and bar-code traceability to avoid the introduction of counterfeit or non-compliant parts.
Yes. Although Class 2 is our baseline for consumer and industrial products, we offer Class 3 assembly for medical device electronics (under ISO 13485) and aerospace autopilot units. This entails rigorous control of barrel fill, solder fillets, voiding criteria, and thorough automated X-Ray testing.
We support multiple inspection and testing methods to guarantee a 100% pass rate. This includes: SPI, AOI, 3D inline X-Ray inspection (for BGA void checking), In-Circuit Testing (ICT), flying probe testing, and custom Functional Testing (FCT) designed around your product's schematic specifications.
For quick-turn prototyping, we can deliver assembled boards in 3 to 7 working days (after components are received). Standard production runs usually take 3 to 4 weeks depending on BOM complexity, supplier lead times, and box-build assembly requirements.
Absolutely. We operate separate lead-free and leaded lines. Our factory uses certified RoHS lead-free solder pastes and wave-soldering mixtures, and we comply with REACH and WEEE directives for all global shipments.
