SMT Steel Spacer

SMT Steel Spacer

 

SMT steel spacers are compact fasteners specifically designed for PCB (Printed Circuit Board) assembly, suitable for modern high-density electronic devices. Their lightweight construction and minimal space occupation meet the stringent assembly requirements of precision electronic products, making them core small hardware components in various consumer electronics, industrial control equipment, and communication products.

 

The spacers are made of stainless steel and tin-plated to ensure excellent conductivity, solderability, and corrosion resistance. Their surface mount (SMT) structure allows direct reflow soldering onto the PCB surface, offering advantages such as easy installation, high automation, and cost reduction.
