What Does SMT Mean In PCB Industry

SMT  (Surface Mount Technology):

If you are working in the PCB industry, you must have heard of the SMT. So What does SMT mean in the PCB industry? SMT is a short form of surface mount technology. It is a process of producing an electronic circuit board, whereby components are mounted or placed directly onto the surface of the printed circuit board (PCB), which makes it very easy to assemble and reduces the amount of space required. 

It has really taken off in recent years with its speed and reliability. There are even some people who believe that it will completely replace through-hole technology because of its advantages over traditional methods.

History of SMT (Surface Mount Technology) 

Ever since the 1960s, surface mount technology has been used in electronics. Originally, this process was more expensive than using traditional soldering techniques and had a low success rate for successfully producing a working circuit board. Nowadays, there is no difference in cost between SMT and soldering with the same high success rate of producing fully functional circuit boards. Surface mount technology can be traced back to one patent by Dr. Gerald Pearson from 1965 and has become an integral part of today’s modern electronic devices like smartphones and computers due to its ability to make circuits small enough for use on these smaller objects without compromising functionality or performance. 

SMT Assembly Techniques 

The SMT assembly technique is a common method of assembling electronic components in mass production. The steps that are involved in an SMT assembly include pre-assembly, soldering, reflow soldering, final inspection, and packing. In order to be successful when using the SMT assembly technique, it is important for there to be good design planning from the start as well as good quality control throughout all stages of manufacturing.

Advantages of surface mount technology 

The benefits of surface mount technology are many, from the reduced size and weight to the significant decrease in assembly time. Surface mount technology uses smaller components which allows for a more dense circuit board layout. This density produces improved signal integrity and faster data transmission rates. The use of SMT also reduces assembly time by up to eighty percent! Imagine being able to assemble a circuit board with just two people within an hour or less! This is possible with SMT because there is no need for any type of hand soldering so that it can be done by machine instead. And if you’re looking for a way to produce quicker turnarounds on your designs, SMT is perfect because it can be used in higher volume production runs without compromising quality control standards!”

Disadvantages of surface mount technology 

Surface mount technology is a new and innovative way of manufacturing electronics in which the components are mounted on a printed circuit board. This technique has its own set of advantages but also disadvantages too. These are some things to consider before you decide to go for this method of manufacturing electronics. However, there are some disadvantages to using it.

“For example, SMT production requires a very high level of precision which means that only highly skilled workers can assemble these boards. Additionally, because assembly takes place on an assembly line rather than by hand, errors are more likely to be introduced into the system.”


The purpose of this blog post is to provide you with information about smt in the PCB industry as this technique is widely used by many china pcb manufacturers. There are many benefits associated with using SMT assembly for your printed circuit board design, but it should be noted that there are some drawbacks as well. We hope you have found this article informative and valuable!
