Accelerated Corrosion Verification Platform - iST-Integrated Service Technology

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.

Why does sulfur corrosion failure still occurred on electronics with conformal coating?
How to verify the sulfur corrosion occurrence on passive components and compliance for ANSI/EIA-977 standard
How to Monitor the Severity Level of Air Quality and Ensure Your Product Meet the Verifications of Compliance in ISA 71.04
How to effectivity verify the creep corrosion failure occurrence on electronics?

What can iST do for you

In addition to working with global Tier 1 companies, including Cisco, Dell, Lenovo, IBM, and Dow Chemical in shaping up a creep corrosion research team under International Electronics Manufacturing Initiative (iNEMI), and also joining into the IPC and relevant international projects to provide an integrated turn-key Accelerated Corrosion Verification Platform (ACVP) service. iST also assists the suppliers in assessing the severity levels classification of air quality where their products are exposed to, and also effectively estimate the product corrosion phenomenon with accelerated corrosion tests to reduce risks of product failure occurrence.

The Superiority of iST

iST is the one and only lab in Asia that provides an integrated turn-key ACVP.

Join into international organizations, including iNEMI, IPC, OCP, and ASHRAE as well adopt their project relevant experiences.

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.
