  The Advantages and Disadvantages of Surface Mount Technology (SMT) Surface mount technology is a part of the electronic assembly that deals with the mounting of electronic components to the surface of a PCB. Electronic components mounted this way are called surface-mounted devices (SMD).   SMT was developed to minimize manufacturing costs while making efficient use of board space. The advent of surface mount technology has empowered manufacturers to create intricate circuit boards in smaller sizes. Throughout this article, we'll explore the numerous pros and cons associated with surface mount technology.   Surface mount technology emerged in the 1960s and gained widespread usage in the 1980s, becoming prevalent in most high-end  PCB assemblies  by the 1990s. It involved redesigning conventional electronic components to incorporate metal tabs or end caps that could be directly attached to the board's surface, eliminating the need for wire leads to pass through ...

The electronics manufacturing industry operates with a set of professional abbreviations, often using terms like PCB (printed circuit board), PCBA (PCB assembly), Through Hole Technology (THT), and more. While these abbreviations are second nature to industry insiders, they might be less user-friendly for novices or electronics enthusiasts. In this article, FS Technology aims to demystify two commonly used terms in the PCBA industry—SMT and SMD—by exploring their concepts, applications, and how they interconnect.   What is SMT?   Basic Concept Explanation   SMT, or surface mount technology, represents a modern approach to arranging components on a printed circuit board (PCB). Widely adopted in the PCBA industry, nearly all companies offering PCB assembly services include  SMT assembly  in their repertoire. In the early 1970s, electronic manufacturers relied on through-hole assembly for component mounting and soldering, where component leads were inserted into dr...
