Surface Mount Assembly

Precision, reliability, and innovation define our surface mount technology assembly services. Using advanced automation and expert engineering, we create compact, high-performance circuit boards designed for modern electronic products. From LED lighting to industrial control systems, our surface mount assembly processes deliver efficiency and consistency at every stage of production.

What Is Surface Mount Technology?

Surface mount technology is the process of mounting electrical components directly onto the surface of a PCB, rather than inserting them through holes as in traditional methods. This approach revolutionised PCB manufacturing by allowing smaller, lighter, and more complex circuits to be produced at scale.

In contrast, through-hole and surface mount technology differ in how components are secured. Through-hole components are larger and inserted into drilled holes, while SMT parts such as resistors, capacitors, ICs, and LEDs sit directly on the board. This makes SMT ideal for high-density, automated production.

Common surface mount technology components include microchips, capacitors, and LEDs like the 0603 SMD LED, known for its compact size and reliability. Together, these components enable manufacturers to achieve high-speed performance, exceptional accuracy, and strong mechanical connections.

Our Surface Mount Assembly Process

At First Choice Assembly, our surface mount technology process combines precision engineering with advanced automation to guarantee consistent results across every order.

1. Solder Paste Application

The process begins with applying solder paste through a stencil onto the PCB pads. This forms the base for bonding components securely during reflow.

2. Component Mounting on PCB

Next, our automated surface mount technology machines (pick-and-place systems) position each component with pinpoint accuracy. Whether it’s a standard capacitor or a micro surface mount device LED, every placement meets exacting tolerances.

3. Reflow Soldering Process

Once positioned, boards pass through a reflow soldering process where controlled heat melts and re-solidifies the solder. This ensures robust electrical connections. For complex assemblies, we use double-sided PCB reflow, allowing components on both sides of the board to be bonded without compromising quality.

Precision is key throughout. Our expertise in soldering and surface mount technology ensures optimal temperature control, perfect solder joints, and fault-free performance, whether in surface mount reflow or hybrid assembly involving through-hole components.

Surface Mount Technology Equipment and Quality Assurance

We invest in leading surface mount technology equipment to maintain efficiency and accuracy throughout production. Our facilities feature:

• Stencil printers for uniform solder paste application

• Pick-and-place machines capable of ultra-fine component alignment

• Reflow ovens for stable and consistent reflow processes

• Automated inspection tools including AOI and X-ray systems

For projects that integrate both SMT and through-hole components, flow soldering is used to complete hybrid builds without compromising quality.

Every board undergoes rigorous quality checks to ensure durability, reliability, and full compliance with client specifications. We are proud of our reputation for delivering assemblies that meet strict performance standards across a range of industries.
