Indium Corporation Technology Experts Presenting at APEX

Apr 09, 2010

Five of Indium Corporation's technology experts will present their technical findings at APEX in Las Vegas, Nevada, April 6-9, 2010.

  • Ning-Cheng Lee, Ph.D, Vice President of Technology

  • Ronald C. Lasky, Ph.D. PE, Senior Technologist

  • Mario Scalzo, Senior Technical Support Engineer

  • Eric Bastow, Senior Technical Support Engineer

  • Chris Anglin, Applications Development Engineer

Dr. Lee is presenting three papers:

Lead-Free Flux Technology and Influence on Cleaning.

Lead-free, cost pressures, and the never-ending question of "how clean is clean?" present assembly operations with constant challenges. This paper addresses those challenges. Tuesday, April 6 – 1:30 - 3:00pm

Selection of Dip Transfer Fluxes and Solder Pastes for PoP Assembly.

This paper discusses the market outlook, assembly process methodologies and key infrastructure elements that have evolved to enable integrating the new generations of high-performance discreet logic and memory die elements within a single package outline. Wednesday, April 7 – 10:15 – 11:45am

Achieving High Reliability Low-Cost Lead-Free SAC Solder Joints Via Mn or Ce Doping.

In this study, low Ag SAC alloys doped with Mn or Ce were evaluated against eutectic SnPb, SAC105, and SAC305 for JEDEC drop, dynamic bending test, temperature cycling, and cyclic bending tests. Wednesday, April 7 – 1:30 – 3:30pm

He will also be presenting a professional development course:

Achieving High Reliability for Lead-Free Solder Joints – Materials Consideration.

This course addresses how multiple factors contribute to failure modes, and how to select proper solder alloys and surface finishes to achieve high reliability. Friday, April 9 – 9:00am – 12:00pm

Dr. Lasky will be presenting a professional development course:

Lead-Free Reliability

This course will cover how to develop a strategy for compliant electronic assembly with high yields and excellent reliability while complying with global environmental regulations. Thursday, April 8 – 9:00am – 12:00pm

Mario Scalzo will be presenting the paper:

Addressing the Challenge of Head-in-Pillow Defects in Electronics Assembly.

This paper discusses the head-in-pillow failure mode and a strategy to minimize this troublesome defect. Wednesday, April 7 – 9:00 – 10:00am

He will also be presenting a paper authored by Tim Jensen

Challenges for Implementing a Halogen-Free Process.

Replacing halogenated compounds can have a dramatic affect on the PCB assembly process. This paper discusses those challenges, as well as techniques and practices that help ensure high end-of-line yields and continued reliability. Thursday, April 8 – 10:15 – 11:45am

Eric Bastow will be presenting:

Understanding SIR.

This paper will discuss the issue of SIR coupon preparation, board cleaning techniques, and how board. Wednesday, April 7 – 10:15 – 11:45am

Chris Anglin will be presenting the paper:

Stencil Printing Transfer Efficiency of Circular vs. Square Apertures with the Same Solder Paste Volume.

This paper addresses the issues associated with stencil and squeegee design and the printing of paste for small passives. Thursday, April 8 – 10:15 – 11:45am

Indium Corporation is also exhibiting at booth #441.

Sponsored by IPC, this technical conference is known worldwide as one of the finest and most selective in the world.
