What is SMT Full Form?

The SMT full form is Surface Mount Technology. Initially, it was called planar mounting. In this method, electrical components are directly mounted onto the surface of a printed circuit board (PCB). The electrical component that has been mounted in this manner is called a surface mount device (SMD). This has largely replaced the through-hole technology in the industry. SMT allows increased manufacturing automation which improves quality and reduces cost.

When to Use SMT?

The following are the cases in which it is suitable to use SMT:

• When you need to adjust high-density of components 
• It is used when there is a need for small and compact components
• You can use SMT if the requirement is high-speed/frequency functioning of the device
• When there is a need to produce large quantities with automated technology 
• To have the final product sleek and light despite the component density

What are the Advantages of SMT?

The following are the advantages of SMT:

• They have much smaller components compared to through-hole technology
• It enables many more connections per component with much higher component density
• In SMT components can be placed on both sides of the circuit board
• It has a lower initial cost and time for setting up for mass production 
• SMT has better mechanical performance than through-hole technology under vibration and shock conditions 
• SMT has simpler and faster-automated assembly. Some assembly machines enable the placement of 136,000 components per hour
