What is SMT Assembly and The Advantages of SMT Assembly?

What is SMT Assembly

Manufacturing circuit boards can go in either of two ways: one is done through through-hole manufacturing, and the other will be the focus of today’s topic, SMT assembly. The latter-stated method is starting to gain popularity among many manufacturers of printed circuit boards for a variety of reasons, namely its many benefits to both the manufacturer and the devices it is installed into.

With that said, we’ll be exploring what SMT assembly is, and then we’ll delve deeper into the discussion by covering its advantages.

SMT Assembly: An Introduction to the Method

Before we proceed to the perks and advantages that SMT assembly methods can provide to you, let’s familiarize ourselves with this method first. The best way to summarize SMT, or surface mount technology assembly, is that it is a form of manufacturing process where components are directly placed on a circuit board’s surface. As a result, it eliminates the need for boring holes into the substrate surface just to embed key components for the circuit board.

The result is a smaller and more compact circuit board that can seamlessly integrate itself into a wide variety of devices.

The advantages of SMT Assembly

SMT assembly has been lauded by many manufacturers as it offers a ton of advantages for their workflow and the outcome of their components and circuit boards. In this section, we’ll explore these benefits in a summarized yet detailed form. Here are some of the perks that this method of assembling printed circuit boards can provide for you.

1. It gives way to the miniaturization of devices

The first advantage that SMT assembly can provide to you is that it gives way to device miniaturization. What this means is that since SMT-made PCBs are way smaller and more compact than through-hole-made PCBs, it allows manufacturers to create more compact versions of previous devices.

A popular example of this case is how our smartphones have evolved from fairly thick bodies to become more compact and less thick as they now use SMT-made circuit boards to empower them.

2. Cost-efficient and cheaper

Even though SMT assembly can be an investment for your company, it is cheaper than through-hole assembly. Since the parts and components will be embedded on the surface of your circuit boards, there won’t be any need for boring holes in the substrate. Therefore, the elimination of drilling holes during the assembly process will contribute to a lower payment bill for the manufactured circuit boards.

As a result, many companies that develop electronic devices often look to SMT-assembled PCBs when working with their partnered manufacturer.

3. Highly responsive devices due to better signal integrity

Another perk SMT assembly provides to your organization is that the products that use SMT-assembled printed circuit boards are more responsive to human input. That’s because since the components and parts are embedded on the surface, combined with their small size, signal transmissions take less time and have no interruptions.

As a result, whenever an individual provides an input to the devices they are using, it immediately processes the inputted command due to heightened signal integrity. One good example is modern computers, where even the smallest inputs are processed quickly and the device proceeds to perform its given task.

4. It works well with mass production through automation

The next perk of SMT assembly is that it can allow the manufacturer to mass produce their circuit boards easily since it can be automated. Through the use of automated equipment such as robotic arms on the assembly line, components are easily mounted on circuit board surfaces with efficiency. It also reduces the cost of manufacturing the circuit boards.

To add to this advantage, SMT-assembled PCBs are far more efficient compared to through-hole PCBs in terms of mass production. Since it eliminates the procedure of boring a hole in parts of the PCB, which is seen in through-hole circuit boards, SMT-made boards are quicker to mass produce.

5. It is versatile and allows for further design customization

The biggest advantage that SMT assemblies can provide to you is their versatility and flexibility. Their PCBs are utilized in a vast array of applications, whether it is for telecommunications, healthcare, or portable devices. It is also capable of operating with mixed-technology PCBs, meaning that machines and devices can operate both SMT-made and through-hole-manufactured circuit boards, which work in harmony. A good example of this scenario is entertainment systems such as audio mixers and systems, which require both types of PCBs to function at their best.

To top it off, SMT-made circuit boards are more customizable. They can be tweaked and modified according to your liking. However, to fully take advantage of this, it is best that you consult your manufacturer so they can have a full grasp of the specifics of the PCBs you intend to utilize for products or your facility’s tools.

6. No space is wasted; every spot is used to its fullest

SMT-assembled printed circuit boards maximize the use of the space that’s allotted on the surface. That means there is a higher density of key components covering the surface of the circuit board, with little to no space left empty. Its maximization of using the circuit board’s allotted space ties into the previously covered advantages, which are miniaturization, heightened responsiveness, and signal integrity.

The more space used to its fullest, the higher its quality and response power it possesses. In turn, it becomes a very reliable component in many devices where this type of PCB is installed, wherein the circuit ensures the full functionality of the device.

SMT assembly makes for quality PCBs and quicker production

To sum up, what we’ve covered, SMT assembly is a process of producing or manufacturing printed circuit boards in which components are embedded on their surface instead of drilled into holes. This method of manufacturing circuit boards also has a lot of benefits for both manufacturers and electronic devices, in that production becomes more streamlined and efficient.

Whereas on the side of devices, SMT-assembled circuit boards ensure that they can seamlessly integrate into their system and allow them to work at their best performance. Whether you are a manufacturer of PCBs or devices, you might soon consider harnessing the potential that SMT assembly can bring to your company due to the advantages it brings.
