Explore production-grade mission-critical assemblies engineered for harsh environments, high-frequency signaling, and long lifecycle stability.
From edge computing platforms to automotive autonomy, modern electronic design requires specialized sub-surface materials, thermal dissipation substrates, and micro-via integration.
Modern microprocessors require dense fan-out solutions. We fabricate stacked micro-vias, via-in-pad plated over (VIPPO), and up to 5-stage HDI stack-ups to optimize electromagnetic emissions and impedance integrity across high-speed signals.
For high-power converters and LED drivers, heat management determines product life. We deliver metal-core PCBs (MCPCB), ceramic backings (AlN, Al2O3), embedded copper coins, and heavy copper layers up to 6oz for extreme current loads.
Eliminate costly wire harnesses while minimizing mechanical vibration failures. Our flex and rigid-flex configurations using DuPont polyimide films solve tight volumetric constraints in medical and avionics assemblies.
Bridging future hardware demands with today's manufacturing capabilities. Our engineering roadmap matches the trajectory of edge computing, electric mobility, and telecommunication protocols.

Each industry carries distinct technical risks. STHL tailors stack-ups, surface coatings, testing, and component qualification to your sector's standards.
Certified to IATF 16949. We build electronic power steering systems, battery monitoring systems (BMS), and motor drives using heavy copper, high-Tg FR-4, and automated conformal coating to withstand mechanical vibration and temperature swings from -40°C to +150°C.
Built under an ISO 13485 quality system. Our processes feature lot-level component traceability, ultrasonic cleaning, and 100% X-ray inspection to prevent hidden defects in telemedicine interfaces, patient monitors, and surgical guidance boards.
Executing IPC Class 3 high-reliability assemblies. Our production includes flight computers, environmental sensor suites, and telemetry packages built with ENIG or immersion silver finishes and functional burn-in testing under thermal cycles.
Built for solar inverters, wind turbine pitch controllers, and grid power quality analyzers. Our boards feature thick-film dielectric pastes, creepage distance controls, and specialized resin-plugged vias for high voltages.
Shenzhen's supply chain enables fast component sourcing, agile manufacturing, and scalable production from rapid prototypes to high-volume builds.
Equipped with high-precision Panasonic and Yamaha placement machines capable of handling 01005 passives, micro-BGAs, and odd-form parts. Every production stage is connected via our proprietary MES platform for lot-level traceability back to specific reels and reflow parameters.
We source parts through direct manufacturer relationships and authorized franchises (Arrow, Avnet, Digi-Key, Mouser). Incoming components undergo XRF material verification, decapsulation checks, and solderability tests to block counterfeit components before they reach feeder lines.
Our team of 50+ engineers provides comprehensive BOM optimization during the quotation phase. We identify end-of-life (EOL) risks, pinpoint active parts with high lead-times, and propose pin-compatible alternative parts to preserve design margins and shorten schedules.
Working with an offshore EMS partner should not compromise your intellectual property, schedule, or compliance track record.
We sign legally enforceable Non-Disclosure Agreements prior to file handoff. Gerber data, schematics, and proprietary firmware are stored on encrypted internal servers with strict role-based access controls to prevent unapproved distribution.
Our bare-board fabrication and assembly plants operate under ISO 14001 guidelines. We verify compliance with RoHS 3, REACH SVHC, and halogen-free directives, providing complete lab documentation to streamline target market customs and environmental approvals.
Quality control relies on verification rather than assumption. STHL runs Automated Optical Inspection (AOI), 3D X-ray Inspection (AXI) for BGA void percentages (<10%), In-Circuit Testing (ICT), boundary scan, and functional test fixtures configured for each client.
Global procurement teams evaluate more than pricing alone. We align with tier-one expectations around lead time, inventory, and supply chain accountability.
Scale without supplier changes. We handle fast-turn engineering prototypes (24-48 hour turns) through the same quality workflows used for pilot runs and multi-thousand unit production runs.
We help smooth market demand swings with buffer stock agreements and scheduled release programs, reducing supply disruptions from long-lead component shortages.
Go beyond bare circuit boards. STHL integrates plastic or metal enclosures, custom wire harnesses, display panels, and firmware loads, shipping drop-test-ready boxes direct to distribution centers.
