12 MONTH 2017 — PFonline.com TECHNICAL PAPERS EDITED BY DR. JAMES LINDSAY, NASF TECHNICAL EDITOR 12 MARCH 2017 — PFonline.com The Bright Design Challenge in Detroit, Michigan, recently featured automotive design students presenting their first research concepts for this year's project and discussing the role of surface treatment and finishing with NASF leaders and experts. Twice each year, students are paired with mentors from the finishing industry and major brands to create innovative concepts with special consideration for how finishing can be used to meet a variety of real-world objectives. For the spring challenge, the 11 students taught by instructor Raphael Zammet at the College for Creative Studies (CCS), facili- tated student presentations showing the class's initial research on the history of automobile brands and how to use finishing to enhance brand identity. Presentations and comments on the students' work thus far were given by a group of NASF leaders part of the Bright Design Task Group including Brian Harrick, KC Jones Plating; Bernie Haviland, Haviland USA; and Mitch Marsh, Finishing Services. A special panel of industry supplier experts from NASF member companies joined the group, providing an overview of the wide range of finishing uses and automotive applications. The panel included Doug Lay, Coventya; Rob Pawson, Haviland USA; Joe Randazzo, Atotech; and Mark Wojtaszek, MacDermid Enthone. NASF board member Brian Harrick, who helped lead the session with key sponsors, is pleased with the outcome so far. "This session really helped the students focus on design," he says. "I think we had a lot of good information exchange and it was great to hear the ques- tions from the students and CCS staff." This semester's course—sponsored by NASF and its training arm, the AESF Foundation—is a studio-focused session of top students in the CCS Master of Fine Arts program. Past graduates from the school involved in NASF-sponsored Bright Design courses have gone on to successful careers working for global automotive and other companies. The objectives of the course and challenge this year is to create new conventions of identity on both the brand and vehicle through the research and application of material, color, texture, pattern and form with surface finishes.

Elimination of Whiskers from Electroplated Tin Masanobu Tsujimoto, Shigeo Hashimoto, Masayuki Kiso, Raihei Ikumoto, Toshikazu Kano and Genki Kanamori, C. Uyemura & Co., Hirakata Japan; Don Gudeczauskas and Al Gruenwald Uyemura USA - Southington, Connecticut As RoHS lead-free regulations began to take hold, tin and its alloys were considered as an alternative to eutectic tin/lead. The industry is constantly adapting materials and processes to the higher reflow temperature profile for these LF solders. Today there is a better understanding of the intermetallic (IMC) bond as well as the reliability of LF solder joints. This paper discusses two approaches to dissipate internal stress leading to whisker formation. The first modifies the substrate surface to control the growth in thickness and direc- tion of propagation of the IMC. The second is to modify the large columnar tin deposit crystal structure to mimic the fine equiaxed structure of tin/lead solder.

Kushner, Kushner Electroplating School, Anaheim, California No surface technology literature is as important—or timeless—in relevancy today as the lectures delivered at the AESF Technical Conferences (later Sur/Fin) by winners of the William Blum Scientific Achievement Award. This month features the 18th Blum lecturer, Dr. Joseph B. Kushner. In his paper, Dr. Kushner discussed the importance of reducing dragout, which he considered to be the main source of plating pollution. Dr. Kushner was also a colorful personality who had a flair for telling stories. Before he launched into the tech- nical discussion, he delighted the audience with how he became involved in the electroplating business and why he became interested in plating rinse waters.
