TJM Electronics was one of the first MIL-STD-2000 certified automated Surface Mount Technology (SMT) companies on the east coast. Since its emergence in 1989, SMT assembly has become one of the most commonly used printed circuit board assembly processes in the electronics industry. It allows for increased manufacturing automation which reduces cost and improves quality.

It is a method in which electrical components are mounted directly onto the surface of a printed circuit board, hence the name surface mount.

SMT Assembly Manufacturing Equipment



Surface mount technology is a flexible assembly process that allows manufacturers to use smaller components with a higher density of connections and a much higher component density on a single board to produce an overall smaller footprint. Component placement can be single-sided or double-sided and does not require drilling through the board as with through-hole assemblies, allowing for a more streamlined and automated-friendly process.

Surface mount boards are also faster and easier to assemble, making them much more cost-effective to manufacture. SMT assemblies are built for stronger mechanical performance to handle shock and vibration conditions better and have more predictable high-frequency performance.

With over 30 years of experience providing SMT assembly services for customers over a wide range of applications, TJM Electronics has the skills and resources to process virtually any PCB assembly project. Whether you need a small or large production run or assistance with prototyping, we can deliver.


TJM is AS9100D certified, and our facility is equipped with highly automated pick and place machines and inspection equipment to provide the highest quality PCBAs.

Our SMT assembly lines are built for quick component placement, processing components down to 01005 and fine pitch down to 0.3mm for Ball Grid Array (BGA), Quad Flat Pack No-Lead (QFN), and Quad Flat Package (QFP).

We also have various reflow oven sizes and automated 3D optical inspection systems that allow for quick and accurate inspection and eliminate human errors.


  • Streamlined assembly process and overall production
  • Allows for smaller components and a higher density
  • Higher density of connection
  • Mitigates risk of human error due to a more automated process
  • Stronger reliability and improved performance
  • Cost-efficient



SMT is favorable for designs with limited space and weight requirements and projects requiring highly customized boards.

TJM Electronics has the equipment and expertise to process SMT PCB assemblies that meet and exceed industry standards. Our automated assembly lines put us at the top of the competition, allowing us to streamline the assembly process while outputting reliable PCB assemblies with quality, correctness, and cost reduction. Choosing TJM as your SMT assembly manufacturer means that your project will ensure the highest level of accuracy regardless of the number of components needed.
