Discover CNC aluminum and steel SMT spacers from ACTKEY - high-precision, automation-ready components manufactured through advanced CNC milling and turning processes. Our CNC machining service provides SMT spacers with consistent quality, ideal for PCB assembly and high-reliability electronics.
An SMT Steel Spacer (also known as SMT Spacer, SMT Steel Standoff, or Surface Mount Metal Spacer) is a precision-machined component used in Surface Mount Technology (SMT) to maintain exact spacing between printed circuit boards (PCBs) and other assemblies, such as enclosures or auxiliary boards.
ACTKEY's CNC machined SMT spacers are typically manufactured from stainless steel, aluminum, or carbon steel, and come in formats such as reel-packaged spacers for seamless integration with automated pick-and-place systems. These spacers help optimize assembly efficiency, reducing manual handling and increasing throughput.
At ACTKEY TECH. CO., LTD., we specialize in the production of CNC machined components tailored for the electronics sector, including SMT PCB spacers, micro CNC parts, and CNC machined SMT stand-off spacers.
Our capabilities include:
- CNC Milling and Turning: High-speed production of cylindrical, hexagonal, and slotted SMT spacers
