What is SMT Assembly?

Surface Mount Technology (SMT) assembly is a highly automated method of mounting electronic components directly onto the surface of printed circuit boards (PCBs), allowing for faster production speeds, higher component density, and improved electrical performance. Unlike traditional through-hole techniques, SMT eliminates the need for drilling, enabling more compact and lightweight product designs.

SMT is the foundation of modern electronics manufacturing, ideal for complex, high-speed, and high-reliability applications across aerospace, medical, defense, and industrial sectors. At Foxtronics EMS, we leverage Surface Mount Technology (SMT) to build robust, space-optimized printed circuit boards (PCBs) that meet the demands of mission-critical environments, all while maintaining tight tolerances and consistent quality.
