Meet Your Directors

Four members of the Board of Directors are elected at the PSMA Annual Meeting held every year during the APEC conference. Each Director serves a three year term and is eligible to be reelected for one additional term.

In this issue we would like to introduce you to John Bultitude, Stephanie Watts Butler, and David Chen.

Dr. John Bultitude
Dr. John Bultitude
Elected March 2023, Term 2023-2026

Vice President, Technical Fellow,
Ceramic Innovation Center
KEMET Corporation
2835 Kemet Way
Simpsonville, SC 29681

I have been developing materials for electronics and multilayer ceramic capacitors for > 30 years and hold 44 US Patents. I have a Ph.D. and B.Sc. in Chemistry from the University of Surrey, Guildford, UK a

Currently I am leading a team of engineers and scientists at the Ceramic Innovation Center of KEMET in the development of multilayer ceramic capacitor-based products for power and high voltage applications.

My association with PSMA began with presentations at 3D-PEIM 2016 and the PSMA Industry Packaging session at APEC 2017. Most recently I have been the Co-chair of the PSMA Packaging and Manufacturing Technical Committee with Brian Narveson and was the Technical Co-Chair of 3D-PEIM 2023 held in Miami Feb 1-3, 2023.

As a Director on the PSMA Board I will support the development of more efficient power sources through the collaboration activities of the Association by expanding membership as well as coloration with other organizations such as IPC and i-NEMI. I believe these PSMA efforts are critical to meet the high efficiency energy conversion needed in the future.
