Level 1: Visual Inspection 
　 1.Manufacturer P/N, quantity, and date code verification 
　 2.Body marking inspection (faded marking, broken text, double print, ink stamps, etc.) 
　 3.Physical conditions inspection (lead bend, scratches, chipped edges, etc.) 
　 4.Taping condition inspection (dented packet, missing parts, etc.) 
　 5.Verify moisture barrier protection verification (vacuum sealed, humidity indicator with specification) 
　 6.Original factory sealed components vs. non-factory seal 
　 7.Any visual irregularities

Level 2: Engineering Review 
　　 Materials identified as questionable during the visual inspection process are reevaluated by Mogultech staff engineers. Product sampling plans are also employed to ensure product consistency. Engineering review includes: 
　 1.Review of level 1 findings 
　 2.Counterfeit databases referenced and updated 
　 3.Label verification (bar code and label review) 
　 4.Manufacturer logo and date log verification 
　 5.ERAI counterfeit alert program

Level 3: Testing 
　　 Product testing is completed to ensure that any questionable materials meet manufacturers’ specifications. Product samples are also periodically tested to ensure product consistency and testing. Testing includes: 
　 1.Decapsulation test 
　 2.Solderability test 
　 3.Surface contamination analysis 
　 4.X-ray examination 
　 5.DC & AC functionality 
　 6.Calibration and capacitance measurement 
　 7.Electrical
