An AI Method for Early Detection of Failures Caused by Corrosion on Components During Assembly - Correlated to Field Failure...

Corrosion is the most dominant failure mode in electronic products. In many cases, the failure seed is corrosion contamination already on the soldering leads before the assembly that propaga .. read more

Materials Compatibility and Aging for Flux and Cleaner Combinations

A materials study of high reliability electronics cleaning is presented here. In Phase 1,mixed type substrates underwent a condensed contaminants application to view a worst-case scenario for .. read more

Characterization,Prevention and Removal of Particulate Matter on Printed Circuit Boards

Particulate matter contamination is known to become wet and therefore ionically conductive and corrosive if the humidity in the environment rises above the deliquescence relative humidity (DRH) .. read more

Dissolution of Metal Foils in Common Beverages

How susceptible are the metals used in modern electronics manufacturing to corrosion by common beverages? This is a question of interest,especially to manufacturers,retailers and to a certain e .. read more

How Clean is Clean Enough - At What Level Does Each of the Individual Contaminants Cause Leakage and Corrosion...

In this investigation a test matrix was completed utilizing 900 electrodes (small circuit board with parallel copper traces on FR-4 with LPI soldermask at 6,10 and 50 mil spacing): 12 ionic con .. read more

Testing Printed Circuit Boards for Creep Corrosion in Flowers of Sulfur Chamber

The iNEMI technical subcommittee on creep corrosion is developing a flowers-of-sulfur (FOS) based qualification test for creep corrosion on printed-circuit boards (PCBs). The test setup consist .. read more

Evaluating Corrosion Resistance of Ceramic Resistors: Mixed Flowing Gas versus Flower of Sulfur Tests

Multi-layer organic laminates which make up over 90% of the present types of interconnecting substrates in today’s electronics can develop a loss of insulation resistance between two biased con .. read more

Capillary IC – A New Platform for High Throughput or High Resolution Separations of Ionic Compounds

High pressure capillary IC allows you to: Lower operational costs – water,waste,consumables “Always Ready” Improved system and analytical performance Convenience Rush samples Enables high-resol .. read more

VOC-free Flux Study Not All WOA (Weak Organic Acids) Are the Same
