<h2 id="introduction" style="line-height: 1.2; display: inline; margin: 0px; font-size: 1.4em;">Introduction</h2>
<p style="-webkit-font-smoothing: antialiased; display: inline; margin: 0px;">The electronics manufacturing industry has evolved significantly over the past few decades, with SMT equipment playing a pivotal role in this transformation. Surface Mount Technology (SMT) has replaced traditional through-hole assembly methods, enabling faster, more precise, and cost-effective production of electronic components. This article explores the importance of SMT equipment, its key components, and its impact on modern manufacturing processes.

<h2 id="what-is-smt-equipment" style="line-height: 1.2; display: inline; margin: 0px; font-size: 1.4em;">What is SMT Equipment?</h2>
<p style="-webkit-font-smoothing: antialiased; display: inline; margin: 0px;">SMT equipment refers to the machinery used in Surface Mount Technology to place and solder electronic components onto printed circuit boards (PCBs). Unlike through-hole technology, where components are inserted into drilled holes, SMT equipment allows for components to be mounted directly onto the PCB surface, leading to higher component density and improved performance.
