Business scope

The Circuit Board Materials Division Division has produced and marketed “Circuit Board Materials” for electronic equipment. This division had marketed paper phenol copper-clad laminations to enter the market at the same time printed circuit boards were developed in our country, in the early stage of the latter half of the 1950’s, and has since established an industry leading position by developing glass epoxy copper-clad laminations and multi-layer Circuit Board Material “Multi” to meet the needs for the functional sophistication and diversification of equipment.

At present, our Circuit Board Materials are widely used in a variety of fields, including network equipment such as cellular phones, servers and routers, digital equipment such as Automotive Components, digital cameras, DVD and flat-screen televisions, and amusement apparatus, like game machines.

To contribute to the evolution of the electronics industry, we have established a management organization to globally ensure product quality by obtaining the ISO 9001 certificate and also for environmental protection by obtaining the ISO 14001 certificate, and promoted global business development in Taiwan, China, Thailand and Europe.

Multi‐layer Circuit Boards Materiais

Multi - layer Circuit boards refer to three-dimensional circuits; built by stacking three or more layers boards and creating through-holes to electrically connect the stacked printed Circuit boards.
This material accounts for about 70% of the domestic sales of this division, covering such fields as computers, various kinds of OA equipment, cellular phones, digital cameras, digital video cameras, network equipment, Automotive components and game machines.
We have continued to develop and market a wide variety of products; acquiring a favorable reputation as Panasonic’s Multi-layer Circuit Board Materials through the use of proven Multi-layer technologies by the early establishment of R&D organization, ready for the advent of the Multi-layer age.

High-frequency Circut Boards Materials

The advent of the IT age has accelerated the transition to GHz bands in wireless communication.
Because satellite or mobile communication assumes a frequency band from 1GHz to 30GHz, a small dielectric loss (low dielectric tangent) is inevitable.
In contrast, high-frequency circuits require stable permittivity that does not vary with environmental conditions, such as temperature and humidity.
We have provided a variety of Circuit Board Materials that meet the above requirements to cope with increasing versatile social needs for handling large amounts of information at high speed.

Double-sided Circuit Board Materials

Glass composite Copper Clad Laminates New CEM-3

Glass epoxy Copper Clad Laminates

There are two types of double-sided Circuit board materials: glass substrate epoxy resin Copper Clad Laminates
and composite laminates combining glasscloth and non-woven　glass fabric (CEM-3).
Our glass epoxy Copper Clad Laminates have been best selling products for OA equipment, measuring instruments and
automobiles since market entry, and our New CEM-3 has also been widely used in DVD drives, amusement machines,
consumer electronics called white goods, and automobile meters, etc.

Single-sided (Double-sided) Circuit Board Materials

Paper phenolic Circuit Board Materials

Paper phenolic Circuit Board Materials are widely used in digital equipment and popular consumer appliances,such as refrigerators and washing machines.
Today, the expanding market for Paper phenolic Circuit Board Materials lies not in Japan but in China and South Asia.
To cope with this market change, we have shifted production sites from Japan to China andThailand.
In addition, the recent market needs are shifting to fine patterns and safety design against fires, due to the electricity for Paper phenolic Circuit Board Materials.
To solve these production issues, we have not only improved the reliability of silver through-hole but also achieved Lead-free soldering production, resulting in the improvement of Printed Circuit Board, electronic equipment and fire safety due to electric problems.

Eco-friendly Circuit Board Materials

Recently, the importance of environmental conservation has been globally recognized and customers are
demanding eco-friendlier compounds for their electronic equipment and Circuit Boards.
With this in mind, we have stopped using halogen and antimony that may produce harmful substances and have instead developed halogen-free Circuit Board Materials,“GX Series” equivalent to conventional compounds in terms of flame resistance.
Furthermore, we have expanded its applications to Multi-layer, and double- and single-sided Circuit Boards to meet various customer needs .
In particular, we have established four production sites in Japan, Taiwan, China and Europe to manufacture halogen-free glass epoxy Multi-layer Circuit Boards materials to meet the needs of a wide range of global applications.
