Deploying state-of-the-art SMT and THT systems to execute high-density component placement on multi-layer PCBs, built in compliance with international aerospace, automotive, and automation regulatory frameworks.
Canada’s modern industrial framework is heavily dependent on reliable, robust microelectronics. Across technology hubs in Ontario (Toronto, Waterloo, Ottawa), Quebec (Montreal's aerospace cluster), British Columbia (Vancouver's IoT & Clean-tech innovators), and Alberta (Calgary's industrial automation and smart grid systems), local businesses require high-standard engineering capabilities.
Whether it is managing severe temperature fluctuations in Arctic monitoring gear, withstanding physical vibrations in heavy oilfield drilling equipment, or delivering failure-free operations in medical support applications, Canadian OEMs need more than simple board assembly. They require comprehensive product lifecycle assistance, Design for Manufacturability (DFM) verification, and certified quality standard compliance.

Backed by structured material sourcing, automated AOI/X-Ray inspection, and functional verification, we serve as a reliable long-term manufacturing partner for businesses requiring high-level precision.
Our technical capability spans both high-precision surface mount (SMT) and high-durability through-hole (THT) assembly technologies, designed to support high-performance industrial requirements.
We assemble high-density component geometries, including Ball Grid Array (BGA) and Ultra-Fine BGA (uBGA) with fine pitch spacing, QFN, QFP, SOIC, PLCC packages, and Package-on-Package (PoP) structures. Utilizing high-resolution automated optical inspection (AOI) and real-time 3D X-Ray laminography, we confirm clean solder joints, accurate alignment, and void-free placement under concealed pins.
Our THT processes are designed for components subjected to mechanical strain. We utilize both manual placement for custom geometries and automated wave soldering systems for large batches. Supported by custom-milled soldering fixtures, ESD-protected assembly environments, and RoHS-compliant lead-free solder alloys, we verify strong, stable connection points across all structural boards.
Our Quality Management workflow subjects assemblies to comprehensive electrical and environmental testing. This includes in-circuit testing (ICT) to locate component defects, customized functional testing (FCT) to verify device operation, and thermal cycling to screen for potential field infant mortality. These testing protocols prevent structural defects and guarantee that delivered units arrive ready for immediate system deployment.
Deploying electronic components in Canada requires strict adherence to distinct national and regional standards. Electronic devices sold in the Canadian market must often carry certifications like CSA (Canadian Standards Association) mark, comply with UL/cUL safety standards, and follow Innovation, Science and Economic Development Canada (ISED) regulations for electromagnetic compatibility (EMC/EMI).
At STHL, our engineering team works closely with your local design teams to review schematic files and BOM layouts (DFM/DFT) before production. This early design review helps ensure compatibility with compliance testing protocols, preventing delays during certification phases.
Additionally, we understand Canada's distinct climate conditions. Industrial systems, outdoor telecommunication hubs, and transit controllers must operate reliably in sub-zero winter temperatures. We provide conformal coating options (acrylic, polyurethane, or silicone) to safeguard critical circuitry against humidity, thermal cycling, and oxidation.
Managing electronics manufacturing involves navigating component availability and logistics. Working with STHL gives Canadian OEMs a direct gateway to the Shenzhen electronics cluster—the heart of the global component supply chain. This physical proximity allows us to source verified, original active and passive components rapidly, bypassing multi-step import delays.
We work directly with primary silicon manufacturers and franchised distributors (Arrow, Avnet, Future Electronics, DigiKey, Mouser) to source parts and secure hard-to-find components during supply allocations, maintaining stable production schedules.
We offer rapid prototyping services to help Canadian engineering departments validate design revisions quickly, accelerating overall time-to-market. Once verified, we scale directly to large-batch production within the same facility.
We handle customs clearance, export declarations, and air/sea freight logistics to primary Canadian hubs, including Vancouver, Calgary, Toronto, and Montreal, ensuring smooth transit and reliable delivery schedules.
The electronics manufacturing industry is evolving rapidly, driven by IoT, edge computing, electric vehicles (EV), and high-power green energy systems. Modern PCBA designs demand tighter spacing, higher thermal dissipation capacities, and lower signal losses. Multi-layer rigid-flex boards and high-density interconnect (HDI) structures are becoming the standard for compact smart devices and wearable healthcare monitors.
At STHL, we address these challenges by investing in our manufacturing systems. Our reflow ovens utilize nitrogen atmosphere environments to prevent oxidation on micro-pads, ensuring clean solder joints for components down to 01005 footprints. Our assembly operations employ automated inspection protocols to verify assembly quality on complex multi-layer designs.
