About this ebook

Surface-mount technology (SMT) is a method for producing electronic circuits in which the components are mounted or placed directly onto the surface of printed circuit boards (PCBs). An electronic device so made is called a surface-mount device (SMD). In the industry it has largely replaced the through hole technology (THT). SMT comes into existence because our earlier version of Through Hole Manufacturing Technology (THT)were having following limitations: 1.Large in Size 2.Only one side of PCB can be used 3.Lesser functions 4.Automation of PCB Assembly restricted 5.Cross Talk becomes predominating factor at Higher Frequency, restricting evolution of Mobile Technology.
