1. Introduction
USB-C HUB teardown articles are valuable for understanding the USB-C HUB internal layout, PCB design, and common parts list across mainstream hubs. In this post, we offer a detailed look inside the device—revealing its materials, structure, and thermal pathways. Whether you’re exploring how to teardown a USB-C HUB safely or want to know what’s inside a USB-C HUB, this teardown delivers engineering insight and practical evaluation.
2. Disassembly Steps
USB-C HUB teardown step by step: Discover how to deconstruct and understand the teardown process of a mophie USB-C HUB.
- Remove rubber feet and screws – usually concealed under pads.
- Split the plastic or aluminum shell – use a thin pry tool along seams.
- Extract the PCB assembly – observe solder joints and connector reinforcement.
- Disconnect cable from PCB – carefully De‑solder or unplug to avoid trace damage.
- Identify modular components – HDMI chip, USB 3.x hub IC, PD controller, Ethernet PHY, filters.
3. Internal Structure Analysis
- PCB Layout: Dense but orderly. High-speed different pairs (HDMI, USB‑A, USB‑C) are matched for impedance, but trace spacing is tight—risking crosstalk.
- Power Delivery Section: Discrete MOSFETs with thermal vias. Some models include a tiny heat spreader, but plastic casings limit efficiency, crucial during a teardown of USB-C HUB.
- HDMI & USB ICs: Mounted close to output port. Their proximity increases EMI potential if shielding is missing.
- RJ45 PHY & Magnetics: On smaller hub boards, isolation may be not enough, risking noise transfer into USB rails.
- Card Reader Slot: Soldered directly onto main PCB, convenient, but vulnerable to mechanical stress.
4. Material & Component Overview
| Component | Observations |
|---|---|
| Shell Material | Plastic hubs rely on internal heat sinks; aluminum ones disperse heat more effectively. |
| Connectors | USB‑C often has two through-hole anchor points; cable strain relief is minimal. |
| PCB Quality | Multi-layer board; via-in-pad used, but possibly lacking underfill. These aspects of PCB design are crucial in a USB-C HUB teardown. |
| IC Quality | Standard-brand hub ICs (GenesysLogic, Realtek); PD controllers from lesser-known Chinese OEMs. |
| Passive Components | Ceramic capacitors and small inductors; EMI ferrite beads present but sometimes undersized. |
| Thermal Features | Few hubs include dedicated thermal copper or graphite pads—usually limited by casing design. |
5. Engineering Highlights & Weaknesses
✅ Positives:
- Compact and modular layout keeps components close to ports for short trace length, which is important when considering USB-C HUB teardown analysis.
- PD power section uses MOSFET arrays and thermal vias.
- Aluminum cases often connected to ground, helping EMI suppression.
⚠️ Weaknesses:
- Tight spacing increases heat and EMI risk, especially in plastic shells without partitions.
- USB‑C connector anchoring is often insufficient—leading to failures under frequent plug/unplug cycles.
- PD and hub ICs run close to each other—thermal interaction may cause throttling.
- Minimal strain relief means cable flexing transmits force to solder joints.
6. Potential Improvements
- Redesign mechanical layout to add port spacing and improve thermal airflow to enhance results in future USB-C HUB teardowns.
- Use underfill for USB‑C connector solder joints to increase durability.
- Include internal EMI shields over high-speed IC clusters.
- Upgrade housing material or add heat spreader to manage heat from PD and hub chips.
- Improve cable strain relief using molded grommet or anchored clamp.
- Standardize quality parts (e.g., PD controllers from reputable brands) for longevity.
