Highly SMT-compatible metal enclosures designed to isolate electromagnetic crosstalk in high-density PCB layouts.
Moscow has fast become the epicentre of Russia's high-tech re-industrialisation program. Key economic clusters in Moscow, including the Technopolis Moscow Special Economic Zone and the microelectronics research facilities in Zelenograd, are experiencing a massive surge in local production of telecom modules, IoT equipment, smart grid components, and automotive electronics.
As the complexity of processing chips increases and wireless transmission protocols transition to higher frequency bands, electromagnetic compatibility (EMC) has turned into a major challenge for hardware designers. Integrated circuits operating in close proximity must be decoupled from ambient RF emissions and mutual crosstalk. Standard shielding frames (экран для печатной платы) manufactured to sub-millimeter tolerances are vital components in modern PCB designs.
Wenzhou Stpete Electronics Technology Co., Ltd. addresses this demand by delivering premium, SMT-compatible EMI shielding frames engineered to withstand complex RF environments, ensuring high-speed data integrity for Moscow's industrial enterprises.
Tailoring shielding frame engineering to meet specific environmental and mechanical challenges across industries.
Base stations, cellular antennas, and routers operate in crowded radio-frequency spaces. Our shielding frames isolate high-frequency RF front-ends, preventing harmonics and signal degradation in modern telecommunications networks across the Moscow region.
For smart telemetry, navigation units, and engine control units (ECUs). These shielding frames ensure resistance to vehicle-induced vibration and temperature variations, protecting complex driver-assistance systems from electrical noise.
Moscow's heavy industrial automation grids generate severe high-voltage spikes and magnetic coupling. Heavy-gauge metal shielding frames shield control boards in programmable logic controllers (PLCs), maintaining stable data cycles.
A comparative engineering breakdown of our standard shielding frame materials designed for different attenuation bands.
| Material Type | Common Thickness (mm) | Shielding Effectiveness (dB) | Corrosion Resistance | Solderability / SMT Yield | Optimal Application Scenario |
|---|---|---|---|---|---|
| Pre-tin Plated Steel | 0.15 - 0.30 | 50 - 65 dB (up to 1 GHz) | Moderate | Excellent (Pre-plated layer) | Cost-sensitive consumer & industrial electronics |
| Nickel Silver (Alpaca) | 0.15 - 0.20 | 60 - 80 dB (up to 5 GHz) | Outstanding (No oxidation) | Excellent (No plating needed) | Automotive, 5G Base Stations, Aerospace RF modules |
| Stainless Steel (SUS 304) | 0.12 - 0.20 | 45 - 60 dB | Excellent | Requires selective tin plating | Ultra-thin packaging, high-stress mechanical modules |
| Beryllium Copper (CuBe) | 0.10 - 0.15 | 70 - 90 dB (up to 10 GHz) | High | Good (requires surface treatment) | High-frequency multi-cavity aerospace applications |
Established in 2005, Wenzhou Stpete Electronics Technology Co., Ltd. is a high-tech enterprise dedicated to the design, custom tooling development, manufacturing, and export of electronic components, connectors, and high-precision shielding frames.
Over the past two decades, we have refined our stamping tolerances down to ±0.01mm and SMT coplanarity tolerances to ≤0.08mm. This rigorous attention to mechanical accuracy guarantees defect-free reflow soldering on our clients' automatic pick-and-place lines. With a strong presence in international trade, we export directly to industrial clients in Moscow, Zelenograd, and the wider EAEU region, providing complete compliance documentation and robust logistical options.

Wenzhou Stpete Electronics ensures a highly resilient supply chain via strategic logistical pathways. Leveraging the China-Europe Railway Express (CR Express) container terminals, we route shipments from Wenzhou to Vorsino and Bely Rast terminals in Moscow within 14 days, offering a cost-effective, reliable alternative to air cargo.
Furthermore, our raw material security is guaranteed by long-term procurement contracts with China's leading metallurgy groups. This limits the impact of global raw metal volatility on our end-client pricing. Through localized custom clearance partners and transparent shipping protocols, we ensure hassle-free custom clearances into the Russian Federation under HS Code 853890 (parts for electrical switches and boards).
Certified operations and advanced machinery to guarantee continuous performance across product batches.
30+ technical R&D engineers, an annual R&D investment of over 15 million CNY, and 21+ active product development patents.
From material incoming inspection to final SMT test verification, we control every single dimensional detail to eliminate batch defects.
Equipped with high-precision high-speed press machines, insert molding equipment, and custom automated assembly configurations.
Our company is fully compliant with ISO 9001, ISO 14001, and ISO 45001 international standards. We supply high-precision electronic connectors, including IF Radio-Frequency terminals, FCB network jacks, DC power outlets, USB sockets, AV pin jack boards, and cooling radiators.
Our hardware production floor relies on automated high-speed stamping presses and multi-spindle CNC equipment. We employ strict quality gates, ensuring optical inspections (2D/3D visual measurement) check coordinate plans to guarantee standard pitch clearances and co-planarity tolerances. Wenzhou Stpete Electronics works with leading national brands, including Huawei and Hisense, proving our reliability on critical telecom and consumer electronics assemblies.
In this summer, our company organized an outdoor team-building activity to strengthen cohesion and foster teamwork. The event took place in a picturesque natural setting, providing a perfect backdrop for enhancing team spirit and collaboration.
The team-building activity was designed to promote unity and cooperation among the employees. Through a series of challenging and fun exercises, the participants had the opportunity to work together, communicate effectively, and problem-solve as a team.
One of the highlights of the day was a series of team-based challenges that required trust, coordination, and quick thinking. These activities encouraged individuals to step out of their comfort zones, build trust in their colleagues, and see the value of working together towards a common goal.
Select and configure shielding frames with full dimensional compliance for regional electronics assemblies in Moscow.
Integrating specialized tactile switches and components to build robust electrical connections.
Anticipating engineering challenges in multi-frequency integration and modular layout designs.
Modern microcontrollers incorporate RF transceiver, power regulator, and high-speed CPU units into single, highly integrated layouts. Rather than implementing multiple individual shields, our technology focuses on single-piece, multi-cavity structures. By forming internal partitions inside a single stamped frame, we isolate distinct RF domains without expanding the PCB area.
To ensure reliable SMT (Surface Mount Technology) yields, keeping coplanarity deviations under 0.08mm is essential. Our production line integrates dynamic laser planarity monitors that measure the bottom edges of the frame before packaging. We offer specialized tape-and-reel (carrier tape) packaging, complete with heat-resistant polyimide pick-up targets, enabling high-speed automatic placement directly from the feeder.
Sealed metallic enclosures act as thermal barriers, trapping heat generated by internal microchips. Our research and development path integrates micro-perforation geometries that allow airflow and convection cooling while maintaining structural integrity. Crucially, the size of these ventilation slots is calculated to remain below 1/20th of the target interference wavelength, ensuring no RF leakage occurs through the ventilation grid.
