How do you ensure quality in the SMT assembly process?

Quality assurance is built into every stage of our SMT process. We use automated screen printing, advanced pick and place systems, controlled convection reflow and vapour phase soldering, and AOI inspection to verify component alignment and solder joint integrity. For complex devices such as BGAs, we use Ersascope inspection to assist with placement and ensure long-term reliability.

What Is SMT Assembly?

SMT assembly is the process of placing and soldering electronic components directly onto the surface of a printed circuit board. Components sit flush on the board, which allows for far greater component density and smaller overall product footprints compared to traditional through-hole methods.

It is the dominant method used in modern electronics manufacturing, from consumer devices through to industrial control systems, medical equipment, and defence applications.

Getting it right demands accurate pick-and-place machinery, tightly controlled soldering processes, and thorough inspection at every stage. That is exactly what you get at Intercole.

Automatic Optical Inspection (AOI)

Our SMT Assembly Capabilities

You have access to a comprehensive range of SMT capabilities, supporting everything from early prototype builds through to high-volume production runs.

Manual SMT Assembly Workstations

For prototype builds, delicate placement tasks, and precision rework, including complex PCB pad and track repairs, dedicated manual workstations give your assemblies the care and attention they need at the most critical development stages.

BGA Rework and Ersascope Inspection

Specialist BGA rework supported by Ersascope inspection technology means you get accurate component placement and reliable long-term performance on even the most complex devices.

Automatic Optical
Inspection (AOI)

Every assembly is verified using automated optical inspection to check component alignment and solder joint integrity before boards leave the facility. You get peace of mind that what arrives with you has been thoroughly checked.

Automated
Pick and Place

Seven Fritsch PA510 single-head automated pick-and-place machines, plus a Fritsch PA610, provide high-accuracy component placement across a wide range of packages. You get consistent, repeatable results whether your order is a small batch or a volume production run.

Automated
Screen Printing

Accurate solder paste application is fundamental to strong solder joints and reliable board performance. Automated screen printing equipment delivers consistent paste deposition, reducing defects and improving overall manufacturing quality.

Engineering
Support

You have direct access to an experienced engineering team who can review your design for manufacture, provide design for test guidance, and help plan your production. Identifying and resolving issues early saves you time and money later in the process.

From Prototype to Full Production

One of the biggest frustrations when developing a new electronic product is the jump from prototype to volume production. Processes that work at small scale can break down when quantities increase, and switching manufacturers mid-development introduces risk you do not need.

At Intercole, you are supported through the entire lifecycle. Whether you need a handful of prototype boards to validate your design or a full production run of thousands of units, you benefit from the same equipment, the same processes, and the same quality standards throughout. That continuity means fewer surprises and a smoother route to market.
