Surface Mount Assembly Services
In the world of modern electronics, space is tight and precision matters. That’s why surface mount assembly has become the go-to method for building compact, high-performance electronic circuits. At Hi-Tek Electronics, we specialize in high-quality, high-speed SMT assembly—offering flexible, customer-first solutions for everything from prototypes to full-scale production.
With nearly 40 years of hands-on experience, we’ve earned our reputation as a trusted partner in electronic manufacturing. Whether you’re a startup building your first product or a manufacturer scaling up, Hi-Tek delivers the accuracy, reliability, and support you need to bring your ideas to life.

What Is Surface Mount Assembly?
Surface mount technology (SMT) assembly is a method of mounting electronic components directly onto the surface of a printed circuit board (PCB). Unlike hole assembly, where component leads are inserted through holes and soldered on the other side, SMT allows for smaller parts—called surface mount devices—to be placed directly onto flat pads.
This technique is ideal for today’s electronics, where high-density layouts and lightweight form factors are the norm. SMT components are quicker to place, easier to automate, and allow for more functionality in less space. From wearables and medical devices to industrial controls and aerospace systems, SMT keeps things small, smart, and streamlined.
Our SMT Assembly Process: Fast, Accurate, Reliable
At Hi-Tek, we’ve refined our SMT assembly process to ensure speed, precision, and consistent quality at every step. Whether you’re producing a single prototype or a full run of production boards, our process adapts to fit your timeline and needs. Here’s how we build your boards:
PCB Design Review
We begin with a careful review of your PCB design files to ensure compatibility with SMT standards and identify any potential issues early.
Reflow Soldering
The board passes through a reflow oven, where controlled heat melts the solder paste, bonding each component in place and creating a strong, reliable solder joint.
Applying Solder Paste
Solder paste is applied to the pads on the board PCB using a stencil and screen-printing process. This paste acts as the glue and conductor for the components.
Automated Optical Inspection (AOI)
After soldering, each board undergoes automated optical inspection (AOI) to check for placement accuracy, solder quality, and potential defects.
Component Placement
Our high-speed pick-and-place machines position thousands of SMT components with precision, following your exact design.
Whether you’re working on lead-free assemblies, complex mixed-technology boards, or require tight lead time turnarounds, our assembly process is built to deliver results you can count on.
Why Use SMT Assembly?
Surface mount assembly is the backbone of today’s compact electronics for good reason. Here’s why so many companies choose SMT:
Space Saving
SMT parts are smaller and can be placed on both sides of the board—perfect for high-density layouts and space-constrained products.
Faster Assembly
Because the process is highly automated, SMT allows for quicker production times and easier scaling.
Reliable Connections
Surface mount devices bond securely to the board, offering dependable performance—even in demanding conditions.
Cost-Effective
SMT is efficient for both low and volume production runs, making it ideal for startups and established manufacturers alike.
While some designs still require hole assembly for structural components or even hybrid or mixed assemblies, most modern electronics rely on SMT for the bulk of their parts. At Hi-Tek, we specialize in both—so you’re covered, no matter your build.

FAQs About Surface Mount Assembly
What is the difference between surface mount and through-hole assembly?
Surface mount assembly places small parts (surface mount devices) directly onto the surface of the printed circuit board (PCB), while through-hole assembly pushes component leads through drilled holes in the board. Surface mount is faster, saves space, and works well for high-density designs. Through-hole is better when you need extra strength for bigger or heavier parts.
Why is surface mount technology (SMT) so popular today?
Surface mount technology (SMT) allows manufacturers to fit more parts onto smaller boards, making devices lighter, faster, and more powerful. It’s also easier to automate, which helps keep costs down and speeds up the manufacturing process.
Can you help if I need both surface mount and through-hole parts on my board?
Absolutely. Many of today’s PCB assemblies use a mix of SMT components and through-hole parts. At Hi-Tek Electronics, we’re experienced in both and can easily handle hybrid boards without slowing down production or raising costs.
What happens if my design isn’t quite ready for manufacturing?
No problem. We’ll review your PCB design and offer suggestions to make the assembly process smoother and more cost-effective. Our goal is to catch small problems early so you can avoid delays later.
When you need PCB assembly done right, Hi-Tek Electronics is the team to call. We combine top-tier equipment, skilled technicians, and personal customer service to deliver the kind of builds that keep your business moving forward.
