What is Surface Mount Technology?
In essence, SMT refers to the approach of mounting electrical components directly onto a printed circuit board’s surface. Electrical components that apply this mounting approach are known as surface-mount devices. SMT results from rapid developments in semiconductor manufacturing, which have provided small outline packages for vast components. First, the solder paste is screen printed on the printed circuit board, and then automatic placement tools are used to reposition the components. Next, we solder the reflow to the substrate. While both through-hole and SMT styles are commonly used, and neither seems to go away anytime soon, SMT is the advanced, more compact mounting style of the two. SMT is ideal if you want to optimize your space utilization as it provides a higher level of circuit reliability. It ranks high among the most economical tech approaches for vast applications. It’s applied in vast electronic product varieties, from smartphones and USB flash drives to portable navigation systems and medical devices.
Benefits of Surface Mount Technology
Virtually all commercially manufactured equipment today uses surface-mount technology for its many advantages during PCB manufacturing. More and more PCB devices are available as SMDs or packages, making SMT convenient and cost-effective.
Virtually every commercially manufactured electrical equipment uses surface mount technology. The approach offers many benefits during PCB manufacturing, and you can choose from a wide selection of packages or SMDs. As a result, SMT adoption can be extremely cost-effective and practical.
The primary benefits of surface mount technology include:
- Automated assembly – Automated pick and place tools can easily install most SMT parts. High volume parts, like passive elements, are loaded into the equipment from reels, while the other components come from trays or tube feeders. This is a vital benefit over PTH assembly that uses manual processes.
- Size – Surface mount technology components are relatively smaller. The PCB designer isn’t required to insert, and solder long leads into holes. So they can fit more elements on smaller board space.
- Availability of parts – SMP components are typically the cheaper alternative, thanks to their volume and size. The surge in popularity and demand also means that these solutions are readily available, and you have vast options.
- Electrical performance – Since more small-sized elements are fitted on a single board, you’ll have shorter signal paths. This can substantially improve the signal board integrity and generate less heat.
Upgrade Your Old Technology
Most new designs are almost exclusively SMT, but sometimes even new designs have a few through-hole components on the same PCB. These few through-hole components are usually specified for components such as connectors, push-buttons, switches, power jacks, and other types of components which are intended to have a direct interface with the user, which are often subject to high forces being applied to them by the user. As a result, through-hole custom PCBs are normally reserved for heavier or bulkier systems and integrations such as semiconductors or electrolytic capacitors in large packages.
The primary reason that through-hole PCBs are still being produced is that many companies are still working with older designs. This can typically be done so long as you aren’t running into major component obsolescence issues. However, there are usually significant cost reductions and quality improvement opportunities to update your through-hole design to an SMT design.
