Surface Mount Technology-Key Drivers & Players in 2022

Surfave Mount TrendsEver since the introduction of the Printed Circuit Board (PCB) happened in 1943, the development of PCB has accelerated at lightning speed. The sizes and speed of digital devices go smaller and faster with each passing year.

Since the need for PCBs increases day by day for every digital device, the commercial manufacturing industry has also developed at an astronomical rate. As the requirements of smaller devices arose among the masses, manufacturing processes related to PCB fitting and PCB assembling also changed with time.

Due to the majority of commercial electronics focused on complex circuitry fitting in small spaces, through-hole electronic components with leads did not cut the mark, leading to a better PCB assembly approach known as Surface Mount Technology (SMT).

Compared to the through-hole technology (THT) used in previous generations, electronic components are now directly mounted onto the circuit board rather than wired.

Surface Mount Technology also offers significant advantages during PCB manufacturing while enabling far more electronics to be packed into a much smaller space.

Apart from reducing size, Surface Mount Technology also supports automated PCB assembly and soldering to be used, bringing significant improvements in reliability and cost-effectiveness.

Before diving into the key drivers of Surface Mount Technology, it will be good to understand what Surface Mount Technology or SMT is all about.

Decoding Surface Mount Technology

SMTAs automation starting at full swing in PCB assembly, through-hole technology posed a lot of difficulties as well as operator intervention due to the exact requirements of pre-formed leads that often missed the holes leading to thorough inspection to keep them tightly.

This led to further issues of stopping the machines and slowing down the PCB assembly process while also increasing the costs.

Surface Mount Technology came as the solution to all these issues with added profits.

Therefore, the use of SMT components rose rapidly due to its easy automation capabilities.

Surface Mount Technology can be simply defined as the process of mounting electronic components to the surfaces of PCBs. It doesn’t call for too much work during the assembly where PCB components are just picked and placed on the board.

Key Trends in SMT in 2022

Changes in Surface Mount Packaging

Surface MountSince miniaturization of PCBs largely depends on the packaging styles during PCB manufacturing, almost all PCB components are now available in forms suitable for Surface Mount Technology with varied sizes.

Dual inline (DIP) packaging was one of the most popularly used packaging for ICs before that possessed two rows of pins for soldering. This has now changed to PGA, QFP, and TSOP type Surface Mount Devices (SMD) packages.

Despite this change, since electronics equipment design requires even higher densities, we started using highly dense SMD packaging in the form of BGAs, LQFPs, and TCPs that are now further leaning towards a new packaging style, namely, chip-scale packaging (CSP) types.

This type of packaging offers better heat dissipation, higher package densities as well improved flexibility.

Environment-Friendly SMT PCB Assembly

Surface Mount workingGoing forward, PCB manufacturers must increase their focus on environment-friendly operations that will lead to thoroughly analyze each phase of the Surface Mount Technology PCB Assembly to figure out all the possible pollution control measures needed.

Likewise, emphasis on lead-free soldering techniques will gradually grow to reduce the carbon footprint and protects its users in the long run. Understandably, the production of halogen and lead-free PCBs will serve as the driving trend for the future.

Lower Costs with Increased Automation

As we see a change in Surface Mount Technology with time, its development due to automation will also progress leading to reductions in costs and improved efficiency for users.

Boards will be further adjusted to suit different customer requirements and applications to achieve higher performance with greater flexibility.
