【Product Overview】USB AF Full SMT Female Connector (1.2 Harpoon SMT Mounting Legs for Strong Board Locking / Rolled Edge Opening to Prevent Pull Damage / Pure SMT Mounting Process / 4Pin USB 2.0 / White High-Temperature Resistant Plastic Core)

USB AF Full SMT Female Connector (USB Type-A Female SMT Mount Receptacle with 1.2 Harpoon Board Locks & Rolled Edge) is a product specifically designed for Ultra-thin laptops, industrial control motherboards, automotive multimedia, smart gateways, and high-density SMT motherboards A high-reliability full SMT connector built for these applications.

In modern high-efficiency electronics manufacturing, the pure SMT mounting process eliminates the need for DIP through-hole wave soldering, significantly boosting SMT line capacity. This product achieves this through Pure SMT mounting architecture + 1.2 harpoon-style positioning legs + rolled edge curved guide opening + high-temperature resistant white plastic , with the following core advantages:

• 1.2 Harpoon-style SMT Mounting Positioning Legs (Peel Resistance and Prying Resistance): The shell is equipped with 1.2 harpoon-shaped SMT mounting legs, which provide ample solder wetting during reflow soldering. After reflow, they firmly rivet and lock onto the PCB pads, completely resolving the common issue of traditional pure SMT connectors easily detaching or losing pads.
• Rolled Edge Design (Smooth Guidance and Scratch Prevention): The front opening of the shell is finely rolled and chamfered, providing excellent physical guidance during insertion and removal, ensuring smooth plugging/unplugging and preventing jamming or scratching of the connector.
• Pure SMT High-Efficiency Placement Process (Eliminating DIP Soldering Steps): Both the data terminals and the positioning shell feet feature an SMT flat-mount structure, fully compatible with high-speed placement machines using Tape & Reel automated suction operation, significantly reducing manual production costs.
• 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.
• White High-Temperature Engineering Plastic (UL94-V0 Rated): The internal insulating core uses distinctive white high-insulation LCP/PBT material, which does not melt or lose pins during 260°C reflow soldering.
