A surface-mount technology (SMT) assembly is a type of electronic component that’s typically found in consumer electronics, smartphones, and other small gadgets. These components are often referred to as “SMT parts” or simply “SMT parts” because of their small size and the fact that they are typically mounted on printed circuit boards (PCBs) using surface mount equipment.
A surface mount technology assembly is a nanometer-level component consisting of thousands of individual electronic components all mounted on an epoxy resin substrate using SMT assembly equipment. These components are then soldered into place with high voltages and pressures. The result is a finished product that looks very much like the original device it was designed to replace – with the addition of a few new benefits that can make it easier to manufacture products, reduce production costs, and improve end-user experiences.
What is surface mount technology?
Surface mount technology (SMT) is a manufacturing method that uses tiny highly precisely machined parts that are mounted on a printed circuit board (PCB) in place of the more conventional internal components. SMT operation is highly accurate, repeatable, and highly automated. This process begins with selecting the right tool for the job.
The next step is choosing the right board. Printed circuit boards (PCBs) are manufactured with different size boards for different applications. For example, the thickness of printed circuit boards can vary from as few as 100 micrometres (um) to 6 um, depending on the application.
How surface-mount technology works?
SMT is a two- step process. The first step is to create a mechanical makeshift that deposits the components onto the PCB. The second is to etch the components using a removes the air bubbles using a mathematically tuned etching process. In this step, the board is etched to release the components and create a Printed Circuit Board (PCB).

Why is surface-mount technology important?
Despite being less expensive than Through- Hole Manufacturing, surface mount technology has been around for 40 years. It has been developed exclusively with the purpose of building small, low-cost, and highly accurate electronic components. And with the growing trend towards smaller electronic devices, SMT has become even more important due to its increased accuracy and production efficiency.
SMT equipment: the heart of surface-mount technology
The heart of surface-mount technology is SMT equipment. The equipment has several parts, including the feeder, dielectric, bed, plier, and cutter. The feeder contacts the workpiece and transfers its electrical signals to the dielectric through the plier.
Dielectrics control the operation of the device and are used to isolate certain circuits. The pliers remove the burrs from the components and prepare the boards for soldering. The boards are then soldered to create a complete device.
How to make the switch to SMT
There are a few steps to make the switch to SMT. The first is to check if the application is suitable. Next, the load-test must be done to make sure that the device can handle the increased load. The next is to change the production process to produce smaller, more intricate parts.
The last is to change the tools used to perform SMT. SMT equipment is relatively expensive and difficult to maintain. Therefore, it is recommended that applications that use SMT be change to another tool if it is not possible to change to SMT.
5 important things you need to know about SMT
- SMT components are tiny: The smallest SMT component is 4 mils (0.15 micrometers) in diameter. Generally, SMT components are much smaller than that.
- SMT components are highly precise: The smallest SMT tolerances is less than 0.1 percent. However, most SMT tolerances are less than 0.2 percent.
- SMT components have a small footprint: Since these components are mounted on a PCB, they are small enough to be concealed in a device.
- SMT components have high heat dissipation: Since these components are mounted on a PCB, they can generate high heat. Also, the small size of these components helps to dissipate the heat.
- SMT components are easy to produce: Since these components are mounted on a PCB, it is very easy to produce them.
What are the benefits of surface-mount technology?
There are a few benefits of SMT that set it apart from other manufacturing techniques. One of the main benefits is the smaller device it can fit in. In some cases, it is possible to reduce the size of an SMT component by a factor of 50 or more. For example, a micro USB plug can be as small as the original device it is replacing. In other cases, the part can be 0.001 inch in size.
