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.

Comparing Soldering Results of ENIG and EPIG Post-steam Exposure

09/11/2019 | Jon Bengston and Richard DePoto, Uyemura International USA
Electroless nickel immersion gold (ENIG) is now a well-regarded finish used to enhance and preserve the solderability of copper circuits. Electroless palladium immersion gold (EPIG), meanwhile, is a new surface finish also for enhancing and preserving solderability—but with the advantage of eliminating electroless nickel from the deposit layer. This feature has become increasingly important with the increasing use of high-frequency PCB designs whereby nickel’s magnetic properties are detrimental.

Solder Mask Evolves into a Truly Additive Process

09/09/2019 | John Fix, Taiyo America Inc.
The 5G era is creating quite a bit of work for many PCB engineers as the materials required to keep up with the speed, frequency, and latency requirements need to be defined and qualified. Solder mask, for example, now becomes a truly additive process. Read on to find out how and why.

Selecting the Proper Flex Coverlayer Material

09/06/2019 | Dave Lackey, American Standard Circuits
Coverlayers are polymer materials used to cover and protect the copper traces of the flex circuit product. There are a number of different options available for protecting the circuits, and they serve different design requirements in terms of cost, performance, and flexural endurance optimization. When specifying the choice, it is critical to call out not just the type of coverlayer material but also the thickness requirement. This can be very important in certain types of constructions, especially when a flex circuit will experience dynamic flexing during use.
