Indium Corporation Technologists to Present at SMT Hybrid Packaging
March 20, 2013
Indium Corporation’s Ning-Cheng Lee, Vice President of Technology; Karthik Vijay, Technical Manager – Europe, Africa, and the Middle East; and Wolfgang Bloching, Regional Sales Manager – Germany, Austria, and Switzerland, will present at SMT Hybrid Packaging in Nuremberg, Germany, April 16-18, 2013.
Dr. Lee will present two tutorials:
- Solder Defects for Advanced SMT Manufacturing – Formation Mechanism Troubleshooting. This tutorial will address the following solder defects for advanced SMT manufacturing:
- Head-in-pillow
- Graping
- QFN voiding
- Micro-voiding on immersion silver
- Fragile BGA solder joint and polymeric reinforcement
- Creep corrosion
- Electromigration – The Hurdle for Miniaturization and High-Power Devices. This tutorial will examine the electromigration phenomenon, including:
- The effect of current density and temperature
- The path through Al and Cu solder
- The effect of solder grain orientation
- The effect of solder composition and solder volume
- The resistance of solder joints, and more
Vijay will deliver a tutorial, titled Lead-free SMT Assembly for High Reliability, Yield, and Throughput. The tutorial will cover selecting the best solder alloy, evaluating solder pastes, discussing different PWB pad finishes, and the effect of lead-free reflow temperatures on the PWB. After briefly reviewing component lead finishes, he will lead a detailed discussion on optimizing the stencil printing process. Component placement issues will be reviewed and the steps in setting up an effective reflow process will be covered.
Bloching will present Engineered Solder Preforms and Unique Flux Chemistries to Maximize the SMT Process Window. This presentation details the benefits of using solder preforms to address insufficient or excess solder, eliminate rework, and improve first-pass yield and end product reliability in electronics assemblies.
