Use of Lead-Free Laminate DMA and TMA Data to Develop Stress versus Temperature Relationships for Predicting Plated Hole Reliability

Accelerated testing of plated hole life is necessary for economic reasons due to the long time to failure during field operating conditions. One difficulty in performing accelerated testing on .. read more

Low-Silver BGA Assembly Phase II – Reliability Assessment Seventh Report: Mixed Metallurgy Solder Joint Thermal Cycling Results

Some ball grid array suppliers are migrating their sphere alloys from SAC305 (3% Ag) or SAC405 (4% Ag) to alloys with lower silver contents and often with “micro alloying” additions. There are .. read more

Filling in the Gaps in Lead-Free Reliability Modeling and Testing

This presentation discusses critical material properties and test data that are often overlooked in the introduction of new lead-free solder alloys,but are critical to alloy comparison and the .. read more

Solder Creep-Fatigue Model Parameters for SAC & SnAg Lead-Free Solder Joint Reliability Estimation

For many of the Pb-free solders required under the European RoHS directive,there is now sufficient information,primarily in the form of the results of accelerated thermal cycling of various lev .. read more

Reliability Evaluation of One-Pass and Two-Pass Techniques of Assembly for Package on Packages under Torsion Loads
