In 1963, philips company produce the first piece of SMT IC – small outline IC SOIC;Based on the demand for miniaturization of electronic watch, surface-mount Technology of SMT (Surface Mount Technology) arises at the historic moment.

No pin or short pin electronic components installed directly on the surface of the PCB solder;Compare to a pin hole installed, this new assembly technology is called: surface-mount technology,

SMT in the 1970 s, the rapid development of consumer electronics, puts forward the new requirements of automated production of electronic products, electronic components and production equipment for SMT obtained fast development, all kinds of electronic component Chip, surface-mount packaging meet with semiconductor devices have emerged;Stencil screen printing machine, automatic placement machine, reflow soldering system equipment to the production line.

In the 1980 s, SMT components SMC and SMD surface-mount devices and variety increase, prices slashed the number of;SMT penetrated the aerospace, communication and computer, automobile and medical electronics, office automation and home electronics and other fields.

At the same time SMT in mainland China.

SMT is used the most widely in the field of electronic assembly technology.Traditional manual welding technology and electronics assembly technology is THT hole installation technology.Electronic assembly task is to electronic components welding according to the requirement of the design to the printed circuit board.Electronic encapsulation constantly change in the form of promoting the sustainable development of electronics assembly technology and process equipment.Simple and complex of electronic assembly is determined by PCB DFM manufacturability of the design.
