Smart Home Hubs & Docking Stations : Acts as a unified, single-cable solution handling both high-power EPR delivery and high-bandwidth networking, simplifying internal PCB real estate.
Frequently Asked Questions
What is the advantage of the Hybrid DIP+SMT design over pure SMT?
The hybrid design uses Surface Mount Technology (SMT) for the 24 signal pins to ensure high-speed signal integrity, while using through-hole (DIP) stakes for the outer shell. This provides vastly superior mechanical retention strength, preventing the connector from tearing off the PCB during rough handling or high-cycle usage.
Is this receptacle fully compliant with the new 240W USB PD 3.1 standard?
Yes. The contacts are rated for 5A continuous current on the VBUS pins and can handle up to 48V DC, making it fully capable of supporting the 240W Extended Power Range (EPR) specification safely.
What is the standard MOQ and lead time?
Our standard Minimum Order Quantity (MOQ) for tape-and-reel packaging is typically 1,000 pieces per reel. Lead times generally range from 2 to 4 weeks, depending on current manufacturing capacity and custom plating requirements.
Can this connector withstand lead-free reflow soldering processes?
Absolutely. The housing is molded from high-temperature LCP (Liquid Crystal Polymer) rated at UL94V-0, making it fully compatible with standard RoHS lead-free IR reflow and pin-in-paste soldering profiles up to 260°C.
Do you provide 3D CAD models and PCB footprints?
Yes, we provide comprehensive technical documentation. 2D dimension drawings, 3D STEP files, and recommended PCB cutout/layout guidelines are available upon request to assist your hardware engineers.
Overview and Application Notes
Overview: The USB 3.2 Gen2 Type-C Mid-Mount Receptacle is engineered for high-bandwidth data transmission (up to 10 Gbps) and next-generation power delivery. Featuring a space-saving mid-mount (sink board) design with a 0.75mm center height, it is ideal for ultra-thin profile applications. This 24-pin connector utilizes a robust hybrid DIP + SMT termination strategy—surface mount contacts for precise signal integrity and through-hole shell stakes for superior mechanical retention against high mating forces. Fully rated for 240W (48V/5A) Extended Power Range (EPR), it offers exceptional durability with a 10,000-cycle lifespan. As a factory-direct OEM/ODM manufacturer, EDOM Electronics ensures strict quality control and customizable delivery formats for seamless integration into your automated assembly lines.
Application Notes:
-
PCB Cutout & Routing: Requires a precise PCB cutout for the mid-mount installation. Maintain 90-ohm differential impedance for the SuperSpeed TX/RX traces to guarantee full 10 Gbps bandwidth.
-
Thermal & Power Management: When operating at the maximum 240W (48V/5A) EPR rating, ensure substantial copper pour on the PCB VBUS and GND planes to facilitate adequate thermal dissipation.
-
Mechanical Reinforcement: The hybrid DIP+SMT design relies on through-hole soldering for the outer shell stakes. Ensure complete solder fill in the via holes during wave or reflow (pin-in-paste) processes to maximize tear-out resistance.
-
EMI/RFI Shielding: Properly ground the stainless steel outer shell to the PCB ground plane to minimize electromagnetic interference, especially in high-frequency data environments.
