Surface mount technology, commonly known as SMT, is a process of fabricating electronic circuits where components are placed directly on the surface of printed circuit boards. Some of the advantages of Surface Mount Technology for PCBs are summarized below:
Instead of connecting through the holes in the board through the hole technology, the components are positioned directly on the surface of the board. Some SMT components, often referred to as surface mount devices or SMDs, are lighter and smaller than their counterparts, primarily because of the reduced number or total elimination of conductors needed to make holes. With the help of standardization of components as well as design tools, the assembly of parts can be largely automated.
By reducing the need for drilling holes and components, the SMT allows engineers to design the boards with the components to be placed on both sides of the board. The SMT also allows for design flexibility. In other words, engineers can combine SMT with through-hole technology, which provides greater PCB functionality on the same board, reducing the need for multiple boards.
Some of the more distinct advantages of SMT Surface Mount technology for PCB assembly are:
As the need to design for drilling is eliminated, the requirement of connection through the board materials is also reduced. Because the components can be easily placed on both surfaces of the PCB.
As the size of the components is reduced, more components can be placed on a single board, which, in turn, led to fewer board requirements per product. With the increasing demand for lighter and miniaturized products, these attributes are very critical.
Surface Mount Technology connections are less likely to experience failures due to the impact of tremors or vibrations.
As the number of holes is reduced, the size of the board is also reduced. If the functions on the SMT do not increase, this leads to increased packet spacing. This further reduces the number of layer counts on the PCB. Because of this, the cost of the board is also reduced.
By combining with adherence to the manufacturing design, Surface Mounted Technology increases its production efficiency due to the reduction or total elimination of drilling operations along with shorter preparation times.
The advantages are many. Surface mounting technology has now become talk of the day. The world’s leading supplier of innovative materials and solutions for a wide range of industry segments.
