Dr. Jennie Hwang to Address Solder Joint Reliability at SMTAI 2019


Reading time ( words)

Solder joint reliability plays a critical role in the reliability of the entire spectrum of end-use electronic products from consumer to industrial, from computing to IoT, from medical to military applications. In lead-free electronics, solder joint reliability becomes increasingly important to the manufacture and performance of the chip level, package level and board level interconnections. Understanding the essential factors behind solder joint reliability is a necessity to designing and manufacturing reliable products.

On Monday, September 23, Dr Jennie S. Hwang leverages her decades of comprehensive real-world experiences and deep knowledge, having solved most challenging reliability problems, to address solder joint reliability by integrating scientific fundamentals with practical requirements. Join your industry colleagues to hear the true authority in solder joint reliability at SMTA International. Dr. Hwang will discuss relevant and crucial aspects of solder joint reliability at PDC 09 – “Solder Joint Reliability - Principles and Applications.” Attendees are encouraged to bring their own selected systems for deliberation.

Blackfox Trains Veterans for Good Manufacturing Jobs

12/31/1969 | Real Time with...IPC
Blackfox Training Institute has been training manufacturing technologists for over 20 years. Based in Longmont, Colorado, Blackfox is now focused on helping veterans of our armed services transition into good jobs in the manufacturing sector. During IPC APEX EXPO 2020, Editor Nolan Johnson spoke with Blackfox CEO Al Dill about the company's veteran training programs, and how this effort is helping companies fill jobs that might otherwise go unfilled.
