Non-destructive Testing (NDT)
Non-destructive testing is the evaluation of materials without causing damage to the specimen. It is frequently used in a product’s failure analysis, quality testing, and inspection. NDT methods are rapid, reliable, and often standardized techniques used in offline batch inspections, in-line during manufacturing, or on-site inspection without disassembly. A wide range of surface and near-surface detection of defects, flaws, discontinuities, structural inspection, corrosion, and erosion detection is possible with high sensitivity depending on the NDT technique employed.
NDT methodologies are also adapted for micro and nanoscale analysis to inspect PCBs, nanomaterials, and semiconductor packaging. Defect detection, die-attached integrity, sealant integrity, and molding adhesion quality, among others, are possible via NDT techniques.
- The most commonly used NDT techniques include:
- Visual Testing (VT)
- Liquid Penetrant Testing (LPT)
- Acoustic Emission Testing (AET)
- Scanning Acoustic Microscopy (SAM)
- Eddy Current Testing (ECT)
- Ultrasonic Testing (UT)
- Radiography Testing (RT)
- Digital Radiography (DR)
- Magnetic Particle Testing (MPT)
- Leak Testing (LT)
- 2D & 3D X-ray Imaging
- Optical Testing
- Oil & Gas
- Pipeline Industry
- Consumer Goods
- Heavy Machinery
- Element Materials Technology
- Applied Technical Services (ATS)
- Zetec, Inc.
- National Technical Systems (NTS)

Root cause analysis of any failed product, component, or material is the investigative study of why or how it failed, resolve the problem, and prevent the recurrence of failure.
Chemical analysis is routinely performed to identify unknown components, obtain physical characteristics or chemical composition, and determine the quality of materials.
