Application Scenarios
-
Industrial PCs (IPCs) & Machine Vision: The space-saving mid-mount design reduces the vertical footprint in compact industrial chassis while delivering the critical 10Gbps bandwidth needed for high-resolution machine vision cameras.
-
Automotive Infotainment Systems: Provides a ruggedized, high-durability data and charging port for vehicle dashboards, where vibration resistance and a low-profile PCB assembly are essential.
-
Premium Consumer Electronics: Ideal for ultrathin laptops, mini PCs, and smart home hubs where external chassis thickness is highly restricted but legacy Type-A backward compatibility is still required.
-
Telecommunication & Networking Equipment: Serves as a reliable, high-speed diagnostic and firmware update port on enterprise routers and edge computing servers.
Frequently Asked Questions
Why choose a mid-mount (sink board) USB receptacle over a standard top-mount?
A mid-mount design drops the connector profile partially through the PCB, significantly reducing the overall height of the assembly above the board. This is crucial for engineering ultra-thin devices or compact industrial enclosures.
Are these connectors compatible with high-speed automated SMT assembly?
Yes. We supply these USB 3.1 receptacles in Tape and Reel packaging with high-temperature Kapton tape (pick-and-place caps), perfectly suited for standard vacuum nozzle automated placement.
Can you customize the gold plating thickness on the contact pins?
Absolutely. While our standard high-durability option is 30μ" gold, as an OEM factory we can adjust the plating thickness (e.g., Gold Flash, 15μ", or 50μ") based on your specific cycle-life requirements and budget.
Does this Type-A connector support 100W or 240W Power Delivery?
No. High-wattage Power Delivery (like 100W or 240W EPR) is exclusive to the USB Type-C standard. This USB 3.1 Gen 2 Type-A connector is designed for high-speed 10Gbps data and standard VBUS power applications (typically up to 1.5A to 1.8A at 5V).
What is your standard lead time for bulk orders?
For standard factory tooling, sample evaluation takes 3 to 7 days. Mass production lead times generally range from 2 to 4 weeks depending on the order volume and material availability.
Overview and Application Notes
-
Overview: Engineered for next-generation data transfer, our USB 3.1 Gen 2 Type-A female receptacle delivers high-speed performance up to 10Gbps in a space-saving mid-mount (sink board) profile. Designed for hybrid manufacturing, it features surface mount (SMT) data contacts for pristine signal integrity and through-hole (DIP) shell stakes for maximum mechanical retention against repeated insertions. Rated for up to 10,000 mating cycles, this robust connector is ideal for industrial, automotive, and premium consumer electronics. As an experienced OEM/ODM manufacturer, we provide flexible customization options, including selective gold plating thicknesses and automated packaging solutions tailored to your assembly lines.

Application Notes:
-
PCB Cutout & Clearance: The mid-mount (sink board) design requires a precise PCB edge cutout. Verify 3D CAD dimensions to ensure proper shell alignment and mechanical support along the board edge.
-
Signal Integrity: For 10Gbps (Gen 2) operation, strict differential pair impedance control (90 ohms ±15%) is required on the PCB routing leading to the SMT pads.
-
Hybrid Soldering Profile: Utilize a reflow soldering profile suitable for the SMT contacts and high-temperature LCP housing, followed by wave soldering or selective soldering for the through-hole shield stakes.
-
Mechanical Strain Relief: Although the through-hole shell stakes provide excellent anchor points, consider enclosure-based strain relief if the port will be subjected to high off-axis cable pulling forces.
