Today’s electronic gadgets & equipments are miniaturized with each passing day. In the industry it has largely replaced the previous constructionmethod of fitting components with wire leads into holes in the circuit board (also called through-hole technology) and it has totally revolutionized the manufacturing process. Surface Mount Technology (SMT) is method for constructing electronic circuits in which the components are mounted directly onto the surface of printed circuit boards (PCBs). Electronics devices so made are called Surface Mount Devices or MSDs. An SMD component is usually smaller then its leaded counterpart because it has no leads or smaller leads. It may have short pins or leads of various styles, flat contacts, a matrix of balls (BGAs), or terminations on the body of the component (passives), unlike discrete components, SMD components have a huge vareity of packages (size). SMD Technology will be the order of the day for the electronics industry in the coming years. SMD offers Small size, consequent High Packing Density, High Reliability & Improved High Frequency performance. SMD Technology Kit to keep you in pace with the technology revolution.
