Quality Consulting
Based on technology and knowledge accumulated through countless experiences in reliability evaluation and failure analysis
in Fujitsu Limited, we serve you as an adviser for your comprehensive quality improvement activities that includes quality
control on component / module and supplier control.
Also, with know-how in analysis/material technology, we will serve you as your consultant for your material-related issue.
Reliability Evaluation Test
Test Standards
JIS, EIAJ, IEC, MIL, etc., and Fujitsu internal Standards based on the experience
Damp-heat cycle test
(Moisture resistance test)
Taking a method applying conditions for accelerated aging, evaluate degradation in component and constituent materials due to damp heat conditions that assume typical tropical environment.
Moisture sensitivity test
Component is verified for its heat resistibility against temperature conditions applied during mounting.
Vibration test
Identify the point sensitive to vibration assuming possible vibration during transportation by craft, ship, track, etc.
Highly Accelerated Stress Testing
Check for moisture resistance and migration.
This test has effect equivalent to Damp heat test (at 85degC/85%RH) in duration of 1/10 or less.
Temperature cycle test
(Thermal shock test)
Component is evaluated for its robustness against thermal shock, in which temperature rapidly transfers alternately within relatively short period of time.
Insulation test
(Migration test)
Insulator is verified for its insulation capability through applying voltage under damp-heat conditions.
Damp heat biased test
(Temperature Humidity Biased: THB)
Check for moisture resistance and migration.
Pressure Cooker Test (PCT)
Check for moisture resistance and migration.
Good-product analysis
Identify structural weakness
