“FPC Market and Related Technology Trend,” Hirofumi Matsumoto, Nippon Mektron
Nippon Mektron is considered to be the largest printed circuit fabricator in 2015, with ZenDing Technology a close rival. This invited talk highlighted the flex circuit segment of the PCB market:
- FPC market trends: The FPC market has grown by an average of 6.5% to $15.4B in 2015. It is expected to slow to 1.5% over the next seven years to $17.7B in 2022. Of that amount, $4.98B will be FPC assembly.
- FPC primary market and future markets: The mix has changed. In 2000, the applications were: mobile phone—22%, mobile camera—11%, hard discs—24%, digital audio—17%, packaging—13%, LCDS—5%, vehicle—4%, and optical—2%. In 2014, the distribution was: cellular phones—51%, LCD for phones—9%, camera for phones—4%, HDD—10%, automotive—9% computers—6%, cameras—6%, wearables—1% and other—4%
- Smartphone market and related FPC technologies (Figure 13): 17 different kinds of FPCs go into the smartphone and shipments exceeded 1.5 billion sets in 2016, growing to 1.84 billion by 2020 (Figure 14).
- Future FPC markets: The smartphone will continue to grow for medical, emergency, and other social network needs. Other growing markets will be automotive, virtual reality, drones, and IoT/M2M
- Wearable, 5G and IoT markets: These growing markets will demand new materials better suited to their performance and environment. Washable materials, ultra-high-speed films like LCP (30-300 GHz), and disposable film or harsh environment films.
