Our THT and hybrid PCB assemblies power robust commercial DC chargers engineered for demanding climate conditions, extreme thermal stability, and maximum energy efficiency.
While Surface Mount Technology (SMT) dominates consumer devices, Through-Hole Technology (THT) assembly remains the essential standard for heavy industrial power electronics, high-voltage vehicle converters, commercial DC fast chargers, and energy infrastructure operating in extreme climate zones. For industrial procurement teams across the Russian Federation—where equipment must withstand broad temperature fluctuations (-50°C to +50°C), physical vibration, and continuous high-current electrical stress—THT component integration provides unmatched mechanical joint strength, electrical creepage distance, and long-term operating durability.
As a leading THT assembly manufacturer and contract electronics supplier serving international industrial markets, our engineering team combines automated axial and radial insertion with precision selective wave soldering to yield flawless solder barrel fill compliant with IPC-A-610 Class 3 standards.
THT leads extend completely through plated through-holes (PTH) in heavy copper PCBs (4oz to 12oz Cu). This mechanical interlock provides superior resistance against copper foil delamination and solder joint shearing caused by heavy transformers, electrolytic capacitors, and copper busbars subjected to severe mechanical shock.
Power conversion systems experience continuous thermal expansion and contraction cycles. The physical volume of solder within a THT barrel absorbs thermal expansion strain far more effectively than thin SMT solder pads, preventing micro-cracking during sub-zero cold starts in industrial plants and outdoor stations.
For high-voltage DC/DC converters operating up to 900V DC and EV chargers operating at 400V/800V line voltages, THT assembly enables clean physical pin isolation, slot routing, and potting compound flow to eliminate high-voltage arcing and dielectric breakdown.
To deliver uncompromising reliability for heavy industrial hardware, our facility utilizes modern nitrogen-purged selective soldering systems alongside automated dual-wave soldering machines. This ensures complete solder rise through multilayer circuit boards without thermal degradation of surrounding SMT devices.
Quality reliability is backed by complete end-of-line (EOL) automated testing systems. Utilizing our proprietary DTS Test Software ecosystem, every THT-assembled power module undergoes multi-stage validation prior to international dispatch.
Industrial electrification and power conversion equipment deployed in the Russian market encounter environmental and physical operating challenges rarely found in milder climates. Our specialized THT manufacturing processes are custom-tailored for regional project integrators, equipment manufacturers, and infrastructure developers.
Commercial fast-charging stations deployed along major transport arteries like the M11 (Moscow–Saint Petersburg) and M12 (Moscow–Kazan) require continuous high-power delivery (30kW to 240kW+) under sub-zero Siberian winter gusts. THT assembly of heavy magnetic inductors, high-capacity capacitors, and contactor boards ensures zero joint fatigue despite extreme thermal swings and continuous full-duty power delivery.
Heavy mining trucks, drill rigs, and processing plants in regions like Norilsk, Kuzbass, and Sakha operate under relentless structural vibration, abrasive particulate dust, and severe shock loads. Potted THT DC/DC power converters (covering input ranges up to 900V DC) provide reliable auxiliary power to onboard telemetry, motor drives, and electronic controls where standard surface-mount components would fracture.
Urban electric buses, trolleybuses, and tramway auxiliary systems in metropolitan fleets require high-voltage auxiliary power supplies and sinusoidal motor controllers. Our THT PCB manufacturing delivers robust sinusoidal commutated speed controllers (such as the D-Sinus family) offering low torque ripple, high acoustic dampening, and high power conversion efficiency across demanding stop-and-go driving schedules.
Unmanned logistics vehicles (AGVs) operating in automated distribution warehouses and cold-chain storage facilities require compact, potted power conversion modules. THT assemblies utilizing planar magnetics provide high current-carrying capacity in extremely low-profile enclosures resistant to condensation, frost accumulation, and physical impacts.
Exporting industrial electronics and high-power charging hardware into the Eurasian Customs Union requires strict adherence to technical safety and electromagnetic compatibility (EMC) regulations. Our manufacturing systems comply with:
The Russian e-mobility landscape features a unique convergence of fast-charging protocols. While European CCS2 and Japanese CHAdeMO interfaces remain prevalent in existing fleets, modern public infrastructure rapid-charging installations heavily prioritize the GB/T national standard due to increased vehicle imports from Asian manufacturers.
Our fast DC charging platforms (20kW Wallbox units up to 240kW dual-dispenser ground-mounted systems) feature multi-protocol controllers equipped with CAN-bus parameterization, supporting dual-gun CCS2 and GB/T concurrent charging configurations controlled via OCPP 1.6 J cloud networking.
Combining mid-sized manufacturing agility with decades of German power electronics engineering pedigree, we deliver complete turn-key solutions from initial schematic design to fully potted mechatronic devices.
DEUTRONICsystems acts as your dedicated system supplier for high-complexity printed circuit board assemblies, electronic sub-assemblies, and fully packaged commercial products ready for sale.
Beyond EV fast-charging technology, our THT assembly capability powers a vast range of industrial power conversion equipment used in factory automation, rail, and logistics infrastructure.
Key technical, quality, and logistical queries regarding our THT PCB assembly, customized power converters, and commercial charging stations.
For industrial devices deployed in cold environments (down to -40°C or -50°C), we utilize high-grade potting compounds (specialized polyurethane or silicone elastomers) characterized by low glass transition temperatures (Tg) and coefficient of thermal expansion (CTE) matching. This prevents potting cracking or strain on THT solder barrels during rapid cold-start thermal expansions. Furthermore, components are selected according to strict industrial temp grade specs (-40°C to +85°C / +105°C), and boards are coated with moisture-repellent conformal coatings to prevent frost condensation during thermal cycling.
Yes. Our dual-connector DC fast charging stations (ranging from 60kW to 240kW+) support customizable connector configurations including CCS2, GB/T, and CHAdeMO. Integrated smart controller boards with dual-protocol CAN-bus firmware automatically detect vehicle signaling, negotiate power delivery curves, and enable concurrent charging of two vehicles via intelligent dynamic power sharing modules.
All THT and mixed-technology assemblies are produced in accordance with IPC-A-610 Class 2 (Standard Industrial) or IPC-A-610 Class 3 (High Reliability / Automotive / Heavy Industrial). Automated Selective Wave Soldering guarantees a minimum of 75% vertical solder fill ( barrel fill ) across all plated through-holes, with 100% barrel fill routinely achieved on high-power path pins.
Absolutely. Because our engineering development, PCB assembly, selective THT wave soldering, potted encapsulation, and final automated testing are completely integrated under one roof, hardware and firmware adaptations are economically feasible for small, medium, and high-volume production series. We frequently work with OEM equipment integrators who require customized power supplies or converter variants in moderate production runs.
Heavy components undergo secondary mechanical securing prior to wave soldering or potting. This includes heavy-duty mechanical snap-in pins, structural silicone adhesive bonding, aluminum tie-down brackets, or direct chassis mounting via isolated thermal pads. This guarantees structural stability under intense transportation vibration and industrial shock loads.
Every manufactured batch undergoes 100% automated inspection driven by our proprietary DTS Test Software. Testing records include full parametric electrical measurement logs, high-pot isolation test certificates, AOI visual inspection results, and serial-number-specific burn-in charts. These digital test logs are archived for total traceability across the device lifecycle.
