SMT Nuts, Fasteners & Threaded Standoffs
Product Introduction U-TEK SMT Nuts, Fasteners, and Threaded Standoffs are precision-engineered fastening solutions designed for fully automated PCB assembly. They are compatible with standard SMT equipment and IR reflow soldering processes, providing reliable mechanical fastening while improving manufacturing efficiency and assembly reliability.
To support high-speed automated SMT assembly, U-TEK SMT Nuts are supplied with a high-temperature-resistant PI (Polyimide) film on the top surface, allowing standard SMT vacuum nozzles to securely pick and place the component onto the PCB. The PI film can be removed after reflow soldering, leaving a clean and reliable threaded fastening point on the PCB.
Available in various thread sizes, body diameters, mounting heights, surface finishes, and packaging options, U-TEK SMT fasteners are widely used in AI Computing Motherboards, AI Servers, Networking Equipment, Industrial Computers, Notebook Computers, Automotive Electronics, and Other High-Density Electronic Assemblies.
