Upcoming IPC Webinar- High Reliability: Solving Problems with Reliability, Repair and Rework in the Lead-Free Era

High Reliability: Solving Problems with Reliability, Repair and Rework in the Lead-Free Era
Cheryl Tulkoff, DfR Solutions
Wednesday, February 16
10:00 am–11:00 am, Central time

This presentation provides a focused but comprehensive discussion on potential reliability issues that can arise within lead-free processes. All areas of potential risk are examined. For each reliability concern, a brief description is provided, followed by the current state of industry knowledge and an opportunity for risk mitigation based upon the product design, materials, complexity, volumes and customer expectations of reliability. A final summary provides a roadmap for ensuring reliability of lead-free product.

What You Will Learn
  • SAC — background and alternative alloys
  • PCBs — surface finishes, laminates, PTH barrel cracking and CAF, pad cratering, ECM
  • Components — concerns, moisture and temperature sensitivity
  • Solders — second generation alloys, copper dissolution, mixed assembly
  • Wave and Rework — lead-free solder fountain, hole-fill challenges
  • Reliability — shock/drop test results, SAC vs. SnPb, results of alternative alloys, thermal cycling
  • Fatigue — shock and vibration, microstructural stability, HALT/HASS
About the Instructor
Cheryl Tulkoff has over 15 years of experience in electronics manufacturing with an emphasis on failure analysis and reliability. She has worked throughout the electronics manufacturing life cycle beginning with semiconductor fabrication processes, into printed circuit board fabrication and assembly, through functional and reliability testing, and culminating in the analysis and evaluation of field returns. She has also managed no-clean and RoHS-compliant conversion programs and has developed and managed comprehensive reliability programs. Tulkoff earned her Bachelor of Mechanical Engineering degree from Georgia Tech and is an ASQ Certified Reliability Engineer.

DfR at RAMS in Lake Buena Vista, FL: January 24-27

Greg Caswell will be attending the Annual Reliability and Maintainability Symposium (RAMS) and participating in a panel discussion on Solar Reliability with a focus on Concentrated Photovoltaic system reliability. For more information on these topics contact Greg Caswell.

Panel 9E Photovoltaic Reliability Room: Nutcracker 3 Wednesday 8:00 AM-10:00 AM

Renewable energy, of which solar energy makes up a large percentage, is believed to be the fastest growing industry sector in the years to come, of which solar energy makes up a large percentage. Despite significant success in the reliability of photovoltaics (PV), reliability and lifetime issues continue to be one of key factors in the rapid commercialization of PV technologies today. This session will give you an overview of current status, challenges and success of PV reliability for different PV technologies, including crystalline silicon PV, thin film PV, concentrated PV, etc.

Moderator: Wendai Wang, Ph.D., Reliability Manager, GreenVolts, Inc., Fremont, CA


John Wohlgemuth, Ph.D., Principle Scientist - PV Reliability, National Renewable Energy Laboratory, Golden, CO Greg Caswell, Sr. Member of the Technical Staff, DfR Solutions, College Park, MD Patrick McCluskey, Ph.D., Associate Professor, Mechanical Engineering, University of Maryland

DfR at PERM in Coral Gables, FL. January 11-13

Jim McLeish will be providing an update on the status of MIL-HDBK-217 at the Pb-Free Electronics Risk Management (PERM) Consortium meeting in Coral Gables, Florida January 11-13, 2011. For more information or to arrange a meeting, please contact Jim McLeish.

The Pb-free Electronics Risk Management Consortium

About PERM
The purpose of the Pb-Free Electronics Risk Management (PERM) Consortium (formerly known as LEAP) is to provide overarching leadership and coordination of Pb-free electronics risk management activities for the government and industry aerospace and defense communities.

The goal of PERM is to better respond to the long term challenges of Pb-free solders and finishes over a systems life cycle.

The PERM Consortium addresses executive leadership, communications, research coordination, standards, training, advocacy, supply chain, and international cooperation through dedicated task teams and advisory groups.

The PERM Consortium is chartered by the Aerospace Industries Association (AIA) and includes support from DoD, DoE, Army, Air Force, Navy, FAA, NASA, and industry.
