Connecting Power, Signals, and Controls across Challenging Environments with Customized Cable & Wire Harness Systems.
High-voltage solar trackers, wind power distribution grids, and battery storage modules require robust cabling systems that handle environmental extremes, UV exposure, and continuous flex stress without signal degradation.
Autonomous driving processors, T-Box modules, and lidar sensors operate under strict EMI restrictions. Our harnesses employ advanced shielding techniques, heavy-duty overmolding, and high-frequency coaxial lines to keep critical vehicle data noise-free.
Fully compliant with ISO 13485, STHL supplies ultra-clean, bio-compatible cable assemblies for diagnostic consoles, sensors, and operating room monitoring setups, keeping signal loss near zero.
Comprehensive manufacturing, testing, and component logistics to support your electronic devices from prototype to high-volume scale-up.
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 we prepare your products for high-speed protocols, high-voltage requirements, and harsh-environment deployment.
Utilization of high-density aluminum-mylar foils, braided tinned copper, and specialized drain wires to achieve up to 95% shielding coverage for high-speed differential signal lines.
Employing high-durability TPU, PVC, and silicone materials for custom overmolds to withstand chemical washes, high heat, physical wear, and mechanical strain.
Automated stripping, precision crimping with continuous monitor validation, and cross-section analysis to secure gas-tight metal connections that prevent oxidization.
Every wire harness undergoes comprehensive test profiles utilizing specialized test boards, checking for high-voltage isolation, insulation resistance, and accurate pin assignments.
Assuring complete compliance and zero-defect reliability across markets in North America, Europe, Asia, and beyond.
Exporting electronics globally demands rigid adherence to local laws and safety guidelines. STHL maintains certified production systems that facilitate seamless approvals for your final products:
