Premium PCBA solutions customized to endure the challenging climatic conditions and heavy duty applications of Chile's industrial sectors.
Chile has long established itself as the economic bellwether of South America, driven by massive investments in mining, renewable energy, and logistical infrastructure. However, the geographic reality of Chile—ranging from the hyper-arid Atacama Desert in the north to the sub-antarctic, high-humidity southern regions—presents unique challenges for electronic equipment. Industrial devices must withstand wide thermal swings, high UV exposure, thick atmospheric dust, and saline coastal environments.
In northern Chile, copper and lithium mining facilities are operating at altitudes exceeding 3,000 meters. The lower air density at these altitudes reduces natural convective cooling. Therefore, printed circuit board assemblies (PCBAs) used in heavy machinery, telemetry sensors, and automated drilling rigs must incorporate strict thermal management configurations, increased electrical clearance, and high-spec conformal coating (such as acrylic, polyurethane, or silicone) to prevent corrosion from mining acids and heavy dust accumulation.
Chile is leading Latin America in utility-scale solar and wind energy generation. The solar installations in the Antofagasta and Atacama regions require highly robust solar tracker control boards, inverter power modules, and monitoring nodes. These devices must guarantee continuous operational uptime under extreme UV radiation and cyclic day-night temperature changes. Our specialized PCB assemblies offer low-loss thermal substrates and high-voltage isolation pathways specifically tested for solar application architectures.
From the ports of Valparaíso and San Antonio to the salmon farms in the Los Lagos region, electronics are constantly exposed to high humidity and salt-laden sea air. For these applications, we employ marine-grade conformal coatings and select corrosion-resistant components to ensure our PCB assemblies resist salt spray and moisture intrusion, ensuring years of trouble-free operations.
Procurement departments of multinational firms operating in Chile need to optimize their cost-to-quality ratios. Sourcing PCBAs from advanced manufacturers in China provides significant competitive advantages, particularly when backed by the China-Chile Free Trade Agreement (TLC China-Chile). This bilateral agreement eliminates tariffs on the majority of industrial electronics, component assemblies, and machinery parts entering Chile, streamlining logistics and reducing capital expenditures.

We can handle a wide range of advanced components, including:
Our commitment to quality goes beyond component expertise. We utilize advanced inspection techniques, including Automated Optical Inspection (AOI) and high-resolution X-Ray inspection, to guarantee flawless assembly and void-free solder joints.
STHL PCBA also excels in Through-Hole Technology (THT) assembly, which is essential for heavy power systems and high-vibration industrial applications. Our THT services encompass:
From design verification and component sourcing to mechanical box build and final calibration, we provide a complete end-to-end turnkey service.
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 offers 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 assemblies for customers across 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 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 before leaving our factory floor.
The global electronics landscape is moving rapidly toward high-density interconnect (HDI) configurations, Edge AI, and smart sensor integration. In Chile's industrial sectors, this shift translates to smart grids and autonomous machinery. Modern facilities need IoT-enabled controllers that process inputs locally in the mill, mine, or power plant. STHL is dynamically upgrading its production capabilities to support these technical requirements.
For modern communications and computer storage systems, we offer multi-layer PCB design and fabrication (up to 32 layers). These multi-layer designs provide cleaner signal paths and better electromagnetic compatibility (EMC), minimizing the risk of signal failure in telecommunication networks operating across Chile.
To sell or install electrical equipment in Chile, compliance with the Chilean SEC (Superintendencia de Electricidad y Combustibles) standards is crucial. We support our clients by ensuring that our PCBA layouts, component selections, and thermal profiles meet all mandatory requirements. We use flame-retardant FR-4 materials that comply with UL94-V0 and configure testing procedures to simplify the final product's CE/FCC and SEC certifications.
Answers to common questions from Chilean and Latin American procurement managers sourcing electronic contract manufacturing services.
STHL has built a robust supply chain network over the past 20 years. We source directly from component manufacturers and authorized global distributors (such as Arrow, Avnet, Mouser, Digi-Key, and Future Electronics). For critical and hard-to-find components, we subject materials to rigorous testing, including package markings analysis under microscope and electrical parameter validation, completely eliminating counterfeit risks.
For PCB prototypes and quick-turn assemblies, our lead time can be as short as 3 to 7 working days once components are in-house. For mass production runs (e.g., 1,000 to 10,000 units), production typically takes 3 to 4 weeks. Transit times to Chile range from 5-7 business days via air express (DHL/FedEx/UPS to Santiago) and 30-35 days via ocean container to Valparaíso or San Antonio ports.
Yes. We provide automated and manual conformal coating options (acrylic, polyurethane, silicone, or epoxy) according to custom specifications. For mining operations in the Andes, conformal coating is highly recommended. It isolates critical traces from conductive copper dust, lithium dust, high atmospheric moisture, and chemical corrosion.
We prepare complete export documentation, including detailed Commercial Invoices, Packing Lists, Airway Bills / Bills of Lading, and a Certificate of Origin (Certificado de Origen) complying with the China-Chile FTA. This document allows our clients to claim preferential zero-tariff treatment at Chilean customs under the "Tratado de Libre Comercio".
STHL holds IATF16949 certification for automotive electronic components, which requires strict process control, FMEA (Failure Mode and Effects Analysis), and rigorous testing. For medical devices, we hold ISO13485 certification, ensuring full traceability and sterile-compliant production processes. We also hold ISO9001 and ISO14001 certifications.
Yes, we conduct comprehensive Functional Testing (FCT) in-house to verify the operational integrity of the PCBAs. Clients are welcome to provide their own custom-built testing fixtures, software, and guidelines, or our engineering team can design and build custom fixtures in-house based on your schematics, test criteria, and connection requirements.
