high-definition circuit and 1.4-times increase in production
capacity -
The OKI Group PCB business company OKI Circuit Technology
(President: Masaya Suzuki, Headquarters: Tsuruoka City, Yamagata
Prefecture) has set up a new ultra-high-multilayer PCB line at the
Joetsu Plant in Joetsu City, Niigata Prefecture, with full-scale
operations commencing in July. The PCBs produced are incorporated
into equipment for manufacturing and testing semiconductors for
applications involving AI, data centers, and next-generation
communication networks. The new line enables high-precision and
high-definition circuit formation which supports a via pitch (Note
1) of 0.23 mm, while increasing production capacity by
approximately 1.4 times compared to previous levels and
strengthening the capability for manufacturing of a wide variety of
products in small quantities. The company aims to expand sales
targeting manufacturers of semiconductor manufacturing and testing
equipment.
Semiconductors have been evolving dramatically, with increased
functionality, reduced size, lower power consumption, and greater
capacity. Along with miniaturization and multilayering, progress
has also been made in the development of technologies and new
materials to achieve high voltage resistance, large capacity data
processing, and high-speed transmission. This has led to higher
numbers of terminal pins and reduced pitches in order to handle
large-volume data processing. The PCBs used for manufacturing and
function testing of these next-generation semiconductors are
required to have narrow pitch and ultra-high multilayering of more
than 100 layers. This requires the development of new ultra-thin
materials to ensure low thickness, even when multilayered, and
manufacturing technologies such as ultra-fine hole drilling capable
of accurately penetrating microscopic circuits on multilayer
boards.
In this connection, the manufacturing area within the Joetsu
Plant has been expanded by 3,300 square meters (about 1.2 times the
previous area) and now includes a new surface treatment line for
handling ultra-thin materials and additional direct imaging
equipment. The AOI (Note 2) automated inspection equipment has also
been relocated, to optimize the flow of the PCB production process,
improving production quality and increasing production capacity by
about 1.4 times. The new line has also achieved improved line width
accuracy (stabilization of transmission characteristics) by means
of high-precision circuit formation and a high-definition etching
line through the reinforcement of automatic transport and direct
imaging equipment for materials ranging from ultra-thin 0.03 mm to
thick 8 mm boards. As noted by OKI Circuit Technology President
Masaya Suzuki, the installation of additional high-precision
drilling equipment has improved OKI Circuit Technology’s
capabilities in ultra-fine hole drilling (diameters of 0.10 mm or
less), enabling the provision of ultra-high multilayer and
high-definition PCBs with over 110 layers to meet customer demands
for next-generation semiconductor manufacturing and testing.
OKI is currently focusing on its EMS business, which provides
one-stop comprehensive Mono-zukuri services from design to
manufacturing and reliability testing. The installation of this new
line forms part of its technological development and production
ramp-up investment in fields promising future growth within the PCB
business, such as semiconductors, aerospace, defense, robotics, and
next-generation communications. OKI aims to maintain active
development of PCBs and manufacturing technologies in response to
advancements in related technologies.

[Terminology] Note 1: Via pitch Distance between holes (via
holes) that electrically connect conductors; the smaller the
distance, the greater the manufacturing challenges.
Note 2: AOI (Automated Optical Inspection) Automated visual
inspection in the manufacturing of PCBs and LCD panels, which uses
cameras to autonomously scan target components to identify missing
parts, fillet (rounded corner) size and shape, and distortion.
