Testing and Quality Assurance
Dynamic PCB Testing and Quality Assurance at UE
At UE, quality and customer satisfaction are our top priorities. Our approach to PCB testing and quality assurance is dynamic, emphasizing continuous improvement and the application of advanced methodologies to meet our clients’ diverse needs. Utilizing advanced tools and methodologies, including Design of Experiments (DOE) and statistical analysis, we strive to deliver exceptional results.

Comprehensive Testing Methodologies
Our testing capabilities integrate state-of-the-art process control systems and a wide array of certification standards to guarantee product excellence. Key components of our testing processes include:
- Statistical Process Control (SPC): Implementing SPC helps us monitor and control our manufacturing processes, ensuring consistent product quality.
- Automated Optical Inspection (AOI): Our AOI systems provide high-precision visual inspections, detecting defects that might otherwise go unnoticed.
- Metallographic Cross-Section Analysis: This technique allows us to scrutinize the internal structure of PCBs, ensuring the integrity and quality of the materials used.
- Electrical Testing: Comprehensive electrical tests verify the functionality and performance of our PCBs, ensuring they meet stringent requirements.
ISO 9001:2015 Certification
UEC’s robust quality management system, which is certified to ISO 9001:2015 standards, demonstrates our commitment to maintaining a robust quality management system. This certification ensures that our processes adhere to the latest standards, featuring a unified structure across all ISO management systems, incorporating risk-based thinking, streamlined requirements with reduced emphasis on documentation, clearly defined quality management boundaries, and enhanced leadership engagement.


AS9100 Rev D & IATF 16949:2016 Certification
In addition to ISO 9001:2015, UEC’s quality management system is certified to AS9100 Rev D standards and IATF 16949:2016, the global technical specification and quality management standard for the aerospace & automotive industry.
