Testing Services

Ensuring Excellence in every product

At UK-NSI, we understand that quality is non-negotiable in electronic manufacturing. Our comprehensive test services cover Surface Mount Technology (SMT), post-assembly and final assembly, ensuring that every product meets the highest industry standards. With state of the art inspection, in-circuit testing and functional testing solutions, we provide precision, reliability, and traceability for your electronic manufacturing needs.

3D Automated Optical Inspection (AOI)

Our inline 3D AOI systems provide high speed, high accuracy inspection to ensure quality manufactured PCB assemblies. With advanced imaging and real-time defect analysis, our AOI processes ensure:

  • Component Verification:  Checks for presence, correct placement, polarity and size.

  • Solder Joint Inspection:  Evaluates solder volume,  joint quality and detects bridging.

  • Foreign Object & Contamination Detection:  Identifies foreign particles or contaminants that may impact performance.

With AOI as part of our quality control process, we reduce defects, improve first time yield and maintain superior reliability in every PCB we manufacture.

Inline X-Ray Inspection – Hidden Joint Defect Detection

For complex assemblies with hidden solder joints, Ball Grid Arrays (BGAs) and high density components, our X-ray inspection technology ensures that solder connections maintain the highest quality while meeting customer requirements.

Key benefits include:

  • Non-Destructive Testing:  Identifies defects without compromising the integrity of the assembly.

  • BGA & QFN Solder Joint Analysis:  Ensures reliable connections on components with concealed solder points.

  • Void & Short Detection:  Eliminates the risk of electrical failure due to poor soldering.

By utilising advanced X-ray imaging, we detect potential failures before they become critical issues, ensuring long-term product reliability and manufacturing efficiency.

In-Circuit Testing (ICT) 

Our In-Circuit Test (ICT) systems validate electrical performance at the component level, preventing potential defects from progressing further. 

Our ICT capabilities include:

  • Short/Open Circuit Detection:  Ensures proper electrical pathways.

  • Test Jet for Connector Verification:  Confirms correct insertion and functionality of connectors.

  • Component Testing:  Measures passive and active components for proper operation.

  • Basic Functional Testing & Boundary Scan:  Verifies circuit integrity and design compliance.

ICT plays a critical role in minimising costly rework and ensuring that every unit leaving our facility performs to specification.
