EPTE Newsletter from Japan: Practical Progress in Advanced Materials


Reading time ( words)

FINE TECH JAPAN 2015 – a popular trade show for advanced materials – was held at Tokyo Big Sight a couple of weeks ago. The three-day trade show began on April 8, and included two related events – Photonix 2015 and Advanced Material World 2015. Concurrent shows included Film Tech Japan, Metal Japan, Plastics Japan and Ceramic Japan. More than a thousand companies and organizations were represented at the show and used up all the available floor space. Most of the companies reserved mid- or small-sized booths, and the only foreign companies in attendance hailed from Taiwan and Germany.

The name of the trade show gives away the types of products on display – advanced materials. A few keynote speakers that represented larger material companies featured products that were supposed to be revolutionary, but this was not the case. Their presentations were regurgitated from last year. I remember thinking to myself that these companies have had no significant breakthroughs in technology or processes in the last few years. On the other hand, there were a few smaller companies that introduced a few innovative products that could have some practical use.

Flat panel displays and touchscreen panels used to be the predominant products at the convention; however, a lot of businesses from Japan have already shifted to Korea and Taiwan. For this reason, there was not too much promotional activity or presentations from this segment. Taiwanese companies were very state-of-the art with their displays.  While their booths were relatively small, they exhibited completed display devices including OLED modules and touch panels.

Printable electronics and RTR (Roll to Roll) manufacturing were included in many sales presentations. A few years ago, many companies promoted this segment as the next greatest breakthrough for the industry. Nowadays, many companies that play in these areas no longer promote the segment this way, instead, they displayed some small but practical developments assuming actual applications.

Jujo Chemical rolled out a new transparent conductive paste for a screen-printing process earmarked for flexible optical devices. The basic materials remain the same as previous generations, but the new paste has improved process capabilities with improved physical performances. Asahi Chemical Laboratory introduced a couple of new screen-printable inks – fine silver paste and graphite paste. Mino Group, a major printing equipment supplier, demonstrated a hybrid process for screen-printing and transfer printing for fine printing on non-flat surfaces. And lastly, Nakanuma Art Screen introduced a new screen mask with a high dimensional stability made from a photo-etching process.

Toray Engineering, a major RTR equipment supplier, introduced a couple of new patterning processes using thermal in-printing and laser patterning for fine patterning during the RTR process. Ushio, a major photo device supplier, unveiled a new patterning system called VUV-Aligner for use in printing transistor devices. Fuji Shoko, a supplier of RTR machines, demonstrated a compact RTR stamping machine. There were no innovative technologies on display, but there were many new practical ideas brought fourth from experts who have been in the industry for many years. The machines on display were custom-made, and I am sure that these new RTR machines work with high reliability.

I may have missed a few newly rolled-out technologies and products because the convention was so big. I look forward to next year's show and the chance to discover that one technology that everyone can’t live without.

Microvias: Links of Faith are Not Created Equally

07/18/2019 | Jerry Magera and J.R. Strickland, Motorola Solutions Inc.
Microvias connect adjacent copper layers to complete electrical paths. There are copper-filled microvias, which can be stacked to form connections beyond adjacent copper layers, and staggered microvias, which stitch adjacent copper layers with paths that meander on the layers between the microvias. This article discusses the various laser-drilled microvias and presents SEM photographs to begin the search for the root cause of weak copper interface.

Dissecting the IPC Regional Survey on PCB Technology Trends

07/15/2019 | I-Connect007 Editorial Team
Sharon Starr, Denny Fritz, and Mike Carano talk about the global 2018 IPC Technology Trends Report released early this year—the size of the survey, how it was conducted, the general findings, and regional differences. They also shared their takeaways and regional insights, and the industry outlook over the next five to 10 years.

An Examination of Glass-fiber and Epoxy Interface Degradation in Printed Circuit Boards

07/12/2019 | Bhanu Sood, Michael Osterman, and Michael Pecht, Center for Advanced Life Cycle Engineering
Multilayer organic laminates, which make up over 90% of the interconnecting substrates in electronics (standard FR-4 represents 85% of the substrates used for laminates), can develop a loss of electrical insulation resistance between two biased conductors due to conductive filament formation.
