Bridging High-Reliability Circuit Board Manufacturing with Heavy Mineral Extraction & Automated Infrastructure
Erdenet, situated in Orkhon Province, stands as one of Northern Asia’s most vital industrial nerve centers. Host to the world-renowned Erdenet Mining Corporation (EMC)—one of the largest copper and molybdenum mining and ore-processing complexes on earth—the region’s economy demands exceptionally robust electronic systems. Circuit boards operating in Erdenet face operational conditions far more demanding than standard commercial applications.
Industrial electronics deployed across local copper concentrators, open-pit haulage fleets, crushing plants, and regional power substations are constantly exposed to sub-zero temperatures reaching -40°C in winter, extreme summer dust, intense physical vibration, and unconditioned electrical power grids. Standard commercial PCBs suffer from micro-cracking, trace delamination, solder joint fatigue, and dielectric breakdown when subjected to these thermal shocks and mechanical stresses.
Modern industrial applications in Erdenet require high-density interconnect (HDI) multilayer printed circuit boards capable of processing high-frequency data from remote telemetry units while simultaneously distributing high amperage to motor controllers. Our facility specializes in custom stackups engineered to minimize crosstalk, control differential impedance, and maximize thermal dissipation.
| Parameter / Feature | Standard Commercial Spec | Erdenet Industrial Grade Spec (Our Factory Standard) | Application Advantage |
|---|---|---|---|
| Layer Count Range | 2 – 8 Layers | 4 – 32 Layers (Blind/Buried Vias, Sequential Lamination) | Ultra-high density routing for embedded SCADA & AI controllers |
| Base Material (Laminate) | Standard FR-4 (Tg 130°C–140°C) | High-Tg FR-4 (Tg 170°C–180°C), Rogers, Polyimide, Megtron 6 | Prevents board warping and delamination during severe thermal cycles |
| Outer/Inner Copper Weight | 1 oz (35µm) | 2 oz to 10 oz (70µm – 350µm) Heavy Copper | Sustains high surges in mining inverters without thermal overload |
| Minimum Trace / Space | 4 mil / 4 mil | 2.5 mil / 2.5 mil (Advanced Fine-Line Etching) | Enables miniaturization of telemetry units and sensor nodes |
| Surface Finish Options | HASL (Lead-Free) | ENIG (3-5µ" Au / 100-150µ" Ni), Immersion Silver, ENEPIG | Superior solderability, contact pad longevity, oxidation resistance |
| Conformal Coating | Optional / None | Acrylic, Silicone, Polyurethane (Automated Selective Coating) | Impervious to mining dust, moisture, chemical vapors, and ice formation |
Maximizing Procurement Efficiency, Lead-Time Certainty, and Total Cost of Ownership (TCO)
Our smart manufacturing facility leverages fully automated LDI (Laser Direct Imaging) exposure, high-speed SMT placement lines, and inline 3D AOI (Automated Optical Inspection) + 3D AXI (X-Ray Inspection) to deliver zero-defect multi-layer printed circuit boards tailored for heavy equipment.
Located with seamless connectivity to the Tianjin Port freight routes and Trans-Mongolian rail logistics (via Erenhot / Zamyn-UÜd to Ulaanbaatar and Erdenet), we guarantee reliable customs handling, express air freight options, and reduced door-to-door delivery schedules for operational maintenance contracts.
In addition to PCB fabrication, our strategic alliance with global semiconductor suppliers allows us to bypass component shortages. We provide complete turn-key assembly, sourcing original ICs, microcontrollers, memory ICs, and heavy-duty connectors with full traceability.
