Description
Here is the professional e-commerce product description for the surface-mount male version, formatted to match your digital catalog.
Compact Male USB Type-A SMD Connector
Product Overview
This Male USB Type-A SMD (Surface Mount Device) connector is a low-profile, board-mounted plug designed for ultra-slim hardware applications. Engineered to mount directly onto the surface of the PCB, this component eliminates the need for through-hole pins, making it ideal for double-sided PCB designs and automated, high-speed pick-and-place manufacturing.
It provides a secure, streamlined way to add direct-plug USB functionality to modern consumer electronics, compact dongles, and smart wearable charging modules.
Key Features
-
SMD/SMT Integration: Mounts completely on the board surface, optimizing PCB trace routing on the opposite layer and reducing manufacturing steps.
-
Streamlined Form Factor: Enables the production of ultra-thin devices by keeping the physical profile of the connector flush with surface-mount components.
-
Reinforced Mechanical Tabs: Equipped with robust surface ground pads that anchor the metal shield firmly to the board, absorbing the shear stress of repeated plug-in cycles.
-
High-Temperature Performance: Constructed using premium Liquid Crystal Polymer (LCP) engineering plastic to withstand high-temperature reflow soldering without warping.
