Industrial Microscopes in Failure Analysis
When a component fails, identifying the cause of failure is essential for preventing the same problem from occurring again. Failure analysis involves examining a failed component or material to determine what caused the defect, damage, or breakdown. In many cases, the failure originates from small cracks, surface defects, wear marks, corrosion, or manufacturing irregularities that […]
Incoming Inspection vs. In-Process Inspection vs. Final Inspection: What’s the Difference?
A single inspection stage cannot detect every potential defect in a manufacturing process. A supplier may deliver material that appears acceptable but fails to meet dimensional or material requirements. A part may pass an early inspection but develop defects due to process variation during production. Even a completed product that appears visually acceptable may still […]
What Is First Article Inspection (FAI) and Why Is It Important?
Manufacturers strive to produce parts that consistently meet design specifications. However, before full-scale production begins, it is essential to verify that the manufacturing process can produce parts that meet those requirements consistently. This is where First Article Inspection (FAI) plays an important role. First Article Inspection is a systematic verification process performed on the first […]
