USB AF Black Plastic Right-Angle Sink Mount Female Connector (Front Insert Rear Solder / SINK Mount Reduces Device Height / 4Pin USB 2.0 / Black High-Temperature Resistant Plastic Core / DIP+SMT Hybrid Process / Designed for Ultra-Thin Motherboards and Automotive Electronics)

Standard orientation | SINK design greatly reduces overall device thickness | Front-insert DIP mechanical reinforcement + rear SMT precision soldering | 4Pin standard USB 2.0 transmission | Free samples and CAD drawings

This USB AF Black Plastic Right-Angle Sink Mount Female Connector (USB Type-A Female SINK Mount SMT/DIP Receptacle) features a precision design combining a "SINK recessed structure + standard right-angle orientation + front insert rear solder (front DIP positioning pins + rear SMT patch terminals) + black high-temperature resistant engineering plastic." It is specifically tailored for hardware terminals that demand extremely high standards in ultra-thin thickness, pull-out strength, and automated SMT processes. The SINK recessed design embeds the connector body into a cutout on the PCB, reducing the height protruding above the motherboard by approximately 50%, making it a key component for overcoming space constraints in ultra-thin chassis and compact motherboards. The process employs a "front insert rear solder" hybrid architecture: the dual-side insertion pins at the front are inserted into the PCB to provide strong anti-prying and anti-peeling mechanical strength, while the 4Pin conductive terminals at the rear use SMT patch form, perfectly matching high-speed SMT machine automated production. Internally, it uses 4Pin high-conductivity copper alloy terminals, fully compatible with USB 2.0 480Mbps high-speed data transmission and stable power supply. Widely used in ultra-thin laptops, industrial control tablets, automotive central control hosts, network set-top boxes, and various compact electronic devices. 2D/3D drawings and free sample requests are available.

[Product Overview] USB AF Black Plastic Right-Angle Sink Mount Female Connector (Front Insert Rear Solder / SINK Mount for Excellent Thickness Reduction / 4Pin USB 2.0 Transmission / Black High-Temperature Resistant Plastic Core / DIP+SMT Hybrid Process)

USB AF Black Plastic Right-Angle Sink Mount Female Connector (USB Type-A Female SINK Mount SMT/DIP Receptacle) is a product specifically designed for Ultra-thin industrial control motherboards, automotive central control, portable medical devices, ultra-thin laptops, and compact network terminals A high-reliability sink mount connector crafted for these applications.

As electronic products evolve toward thinner and smarter designs, conventional board-mounted connectors often limit overall industrial design due to their height. This product addresses this through SINK recessed embedded structure + front insert rear solder hybrid soldering process + black high-temperature resistant plastic , with the following core advantages:

  • SINK recessed embedded architecture (excellent compression of device thickness): The connector is embedded into a PCB opening, significantly reducing the height protruding above the board surface, easily meeting the stringent stacking requirements of ultra-thin enclosures and compact multi-layer boards.
  • Through-hole front + SMT rear (DIP strong fixation + SMT high-efficiency placement) process: The thickened positioning pins at the front use DIP through-hole wave/reflow soldering for fixation, providing extremely high pull-out resistance and anti-pry strength; the 4-pin data pins at the rear use SMT planar placement, with excellent coplanarity, fully compatible with high-speed SMT placement machines.
  • Standard orientation + black high-temperature engineering plastic (black plastic UL94-V0 grade): Adopting the standard orientation (tongue at the bottom/terminals at the top), conforming to traditional insertion and extraction habits; the insulator uses LCP high-temperature plastic, which does not melt or deform during reflow soldering.
  • 4-Pin Standard USB 2.0 High-Speed Transmission and Stable Power Supply: High-conductivity copper alloy terminals with gold-plated contact areas ensure ultra-low contact resistance, fully supporting USB 2.0 480Mbps high-speed data communication and stable power delivery of 1.5A~2.1A.

[Core Value and Procurement Decision Factors for Different Customer Segments]

1. To PCB Layout and mechanical engineers: Break through ID structural limitations to create ultra-thin products

SINK recessed mounting aligns the connector centerline with the PCB centerline or lowers it, saving valuable Z-axis space for system stacking.

2. To PE and process engineers: Through-hole front + SMT rear balances strength with SMT automation efficiency

The flatness of the rear SMT pins is controlled within 0.08mm, resulting in extremely low solder bridging/cold solder rates; the front through-hole pins provide secondary reinforcement, solving the pain point of pure SMT connectors being prone to pad peeling.

3. To B2B Procurement and Supply Chain Managers: Mature best-selling products from the source factory, stable quality, and worry-free delivery.

Manufactured on Dongguan Sinyin Electronic's mature automated production line, with 100% implementation of continuity and contact resistance testing, large batch stock availability ensures rapid sampling and efficient material delivery.
