Smaller and slim pcb.
Surface mount device advantages.
Weight of these components is also much less.
An electrical component mounted in this manner is referred to as a surface mount device smd in industry this approach has largely replaced the through hole technology construction method of fitting components in large part because smt allows.
Yet despite a severe drop in popularity over the years through hole technology has proven resilient in the age of smt offering a number of advantages and niche applications.
Therefore they occupy lesser space on the smt pcb thus making it smaller and slimmer.
Even though smt has several advantages the technology to surface mount a device also brings with it certain disadvantages.
Introduction minimizing the size of electronic components so that more functions can be achieved in a given volume has been a way of life since the early days of large vacuum tubes.

An electronic device so made is called a surface mount device smd.
2 much higher component density components per unit area and many more connections per component.
Surface mount technology smt permits the creation of smaller pcb designs by allowing components to be placed closer together on the board.
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.
Surface mount technology smt is a method in which the electrical components are mounted directly onto the surface of a printed circuit board pcb.
Devices and products that use smt have a large number of advantages over traditionally routed circuits.
These advantages have ensured that smt has dominated the pcb world since its conception.
Advantages of surface mount technology.
3 lower initial cost and time of setting up for production.
This means devices can be designed to be more lightweight and compact.
When you subject components to mechanical stress it is not reliable to use surface mounting as the sole method of attachment to the pcb.
Disadvantages of surface mount technology.
The advantages of surface mount technology.
Since smd components are mounted or soldered directly on the surface of the board surface mount technology.
These devices are known as smds or surface mount devices.
Smd components are 60 80 smaller in size than their thru hole counterparts.
