UN Broaching Standoff

The UN broaching standoff is a permanent, strong mechanical fastener made to securely mount components onto printed circuit boards. Unlike threaded options, it uses a cold riveting process that bends its shank, creating a strong, vibration-resistant, and electrically conductive connection right in the PCB substrate. This riveted stud gives a stable, reliable spot to attach heat sinks, brackets, shields, or other hardware that’s important for keeping electronic assemblies intact and managing heat.

Advantages

UN broaching standoffs offer precise positioning and resistance to vibration and shock, making them commonly used in electronic devices in automobiles, aircraft, and factories.

Putting it in is fast: you only need access to one side of the board. It can be automated easily too, which cuts down assembly time and costs a lot compared to using nuts or threaded inserts.

This stud gets rid of the risk of threads loosening. It also has good pull-out and torque-out strength, so it stays reliable over time, even in tough environments.

Materials

Q:What materials are commonly used for UN broaching standoff and why?

A:Material selection directly impacts conductivity, weight, corrosion resistance, and cost. These broaching standoffs are made of stainless steel (such as SUS304 or 316) or aluminum alloy. Stainless steel is rust-resistant and durable, while aluminum alloy is lightweight and offers better conductivity than stainless steel. Choosing the appropriate material for the application reduces replacement costs. Stainless steel can be used in humid environments, while aluminum alloy can be used where lightweight materials are required.
