FiddlLink
High-performance integrated connectors featuring optimized electromagnetic shielding, designed for telecommunication racks, industrial automation boards, and IoT gateways.
As Vietnam accelerates its transformation into a global semiconductor and high-tech electronics manufacturing powerhouse, Ho Chi Minh City (HCMC) has emerged as the country’s primary engine for industrial computing, IoT development, and automated factory networks. Industrial zones such as the Saigon Hi-Tech Park (SHTP), Tan Thuan Export Processing Zone, and Linh Trung Industrial Parks host massive electronics operations that demand military-grade, reliable connectivity components.
Our premium integrated RJ45 Connectors with USB are designed specifically to support these environments. By consolidating Gigabit Ethernet data transmission and USB data/power interfaces into a single integrated magnetic module, we help local engineering teams and international OEMs save up to 50% of PCB board real estate, reduce assembly complexity, and mitigate electromagnetic interference (EMI) in high-density factory layouts.
From industrial robotics at SHTP to consumer electronics assembly lines, our products serve:
Smart Factory Automation
Plc-to-PC interfaces, industrial machine vision controllers, and centralized control systems.
Telecommunications Infrastructure
High-density telecommunication switchboards, base stations, and localized edge-computing data centers.
Exploring the physics of magnetic integration and stacked data paths in high-frequency environments.
Stacked connector layouts introduce spatial proximity challenges. Our engineering team integrates high-permeability magnetic cores and proprietary internal metal shielding barriers between the RJ45 data lines and USB 3.0 high-speed differential signal pairs, minimizing Near-End Crosstalk (NEXT) and Far-End Crosstalk (FEXT).
Integrated Magjacks utilize precision toroidal transformers and common-mode chokes. This guarantees up to 1500V AC dielectric isolation, protecting sensitive physical-layer transceiver (PHY) chips from power surges, ground loop differentials, and electrical static discharges (ESD) common in factory automation environments.
Designed for reliability under elevated thermal profiles. Using gold-plated contacts (up to 50u") and high-temperature LCP (Liquid Crystal Polymer) thermoplastic housing compliant with reflow soldering temperatures up to 260°C, ensuring robust solder joints and zero structural deflection.
In designing modern embedded computing architecture, spatial utilization dictates thermal airflow and routing efficiency. Combining a 10/100/1000Base-T RJ45 port with dual stacked USB 3.0 ports reduces the connector footprint on the motherboard edge. However, this configuration requires careful attention to impedance matching. FiddlLink utilizes 3D electromagnetic simulators during structural layout stages to tune the differential trace impedance to exactly 100 ohms for Ethernet and 90 ohms for USB lines, eliminating trace reflections and preserving packet integrity.
| Electrical Parameter | Specification Target | Operational Advantage |
|---|---|---|
| Dielectric Withstanding Voltage | 1500 Vrms minimum (Line-to-Shield) | Prevents voltage spike damage to internal board PHYs. |
| Insertion Loss | -1.0 dB max (1 - 100 MHz) | Guarantees low attenuation over long-distance CAT6 cable runs. |
| Contact Plating | 30u" to 50u" Gold over Nickel | Resists corrosion/oxidation in high humidity zones like HCMC. |
| Operating Temperature | -40°C to +85°C Industrial Grade | Maintains signal integrity in non-climate-controlled factories. |
