Several Reasons why Surface Mount (SMT) is the Preferred PCB Assembly Technique
The evolution of Printed Circuit Boards (PCBs) have range from becoming a compact, efficient and critical component of an extensive diversity of things such as machines, automobiles, computing terminals, PLCs and any other electronic devices. In electronic industries nowadays, PCBs have been a huge stimulus to introducing new developments, technologies and inventions. Other techniques in PCB assembly such as through-hole assembly pales in comparison when it comes to the Surface Mount Technology (SMT) which the most famous technique today. For several reasons, SMT assembly has become the best criterion among all PCB assembly techniques.
The manufacturing processes of PCBs has been solely focused on SMT for reasons that are listed below:
Before SMT has been prevalent throughout the world, the point-to-point and through-hole assembly had been used but because it requires lots of time effort simply since it needs assemblers have to solder pads and connect the existing wires there, which means not only taking time to solder but also changing the energy level spread throughout the PCB. This problem can be solved through SMT because the components are to be soldered on the surface as a replacement for through-hole connection points. The invention of SMT became an essential factor in making manufacturing PCBs automated, helping it to be a time friendly.
Another reason is it decreases the assembly costs. The usage of SMT assembly which is automated takes lesser time than using the older techniques of PCB assembling. Thus, making older PCBs were more expensive to make compared to the way they are assembling SMT today. In addition, for PCBs typically needed by design engineers, the cost that will be used to produce a number of PCBs was tremendously prohibited with the use of conventional assembly techniques. The discovery of the automated technique and packed with its ability to plan the manufacturing of an assortment of small amounts of PCBs continuously, SMT assembly contributed in lowering down the cost of production. Clients who are anxious about the cash they are about to release, they need to make sure that they are capable of the SMT assembly automation.
Lastly, it can enhanced its usability. With the use of SMT assembly, smaller components are used which can make the entire PCB more compact and sleeker and have greater energy efficiency. The listed advantages permitted the modern PCBs to be used in many variations of devices such as laptops, computers, smart phones, and other machines which can only be made with these compressed PCB control board than using the large boards. The electronic circuit design engineers and OEM machinery designers have greatly accepted the concept of SMT-manufactured PCBs for these given reasons.
