Since the global air pollution is rapidly getting worse, electronic products, systems, PCB, connectors and components are suffering corrosion and creep corrosion problem caused by both indoor and outdoor sulfur-containing air pollutants. This leads the early failure of electronic products and reduced the product life time and reliability.
The Superiority of iST
Accelerated Corrosion Methodology
- Mixed Flowing-Gas (MFG) test:
The accelerated corrosion test to simulate long-term exposure in corrosive environment (ASTM B845-97). - Flower of Sulfur (FoS) test:
The accelerated corrosion test to simulate long-term exposure in corrosive environment (ASTM B809-95).
Air Quality Monitoring (AQM)
Air quality monitoring in ambient air, including indoor and outdoor by using pre-treatment metal coupons and fixtures. (ISA 71.04 2013)
Corrosive Reaction Rate/Thickness Measurement
- Coulometric Reduction (CR) analysis:
Measure corrosion rate/thickness in ambient air by using electrochemical methodology (ASTM B825-02). - Weight Gain (WG) analysis:
Measure corrosion rate/thickness in ambient air by using weight gain methodology (ASTM B810-01). - Profilometry analysis:
Measure corrosion rate/thickness in ambient air by using ion milling techniques, including CP, FiB and P-FiB.
Failure and Material Analysis Platform
Including morphology inspection, cross-section, element analysis and ion analysis.
