A New Method for Cleanliness Testing & Validation
When it comes to electronics cleanliness…
What you can’t see CAN hurt you.
Ionic Chromatography
SIR
Visual
Step 1
Cleanliness Testing
Visual Assessment
- Parts mounted on glass for visual inspection
SIR Testing
- SIR testing on component specific boards
- Reveals the impact of residues on electrical performance
ION Chromatography
- Used to identify the specific ionic species present
Step 2
Custom Test Vehicles
Custom Designed Boards
- Mimics the production boards
Custom Selected Components
- Reproduces the specific areas of concern in the process
Duplicates Process and Materials
- Provides a more representative test result
The Difference
Surface Insulation Resistance (SIR)
- We provide component specific boards for SIR testing
- Lets you correlate SIR and IC test results
on the same board using your specific
component set
Diagnostics
- What to do with all the test data?
- Use industry baselines
- Develop your own criteria
- Let us analyze the data for you
Product Acceptance
- We make it easy to go beyond the standard industry tests
Objective Evidence
- The most realistic true objective evidence
