Panasonic's new glass composite circuit board material improves the mounting reliability of electronic circuit board parts, thereby contributing to the long-term stable operation of automotive and industrial equipment.
Osaka, Japan - Panasonic Corporation announced today that it has developed a glass composite circuit board material (product number: R-1785) suited for automotive and industrial equipment. Mass production is scheduled to start in June 2018.
With the ever-increasing use of electronics in vehicles and recent trend toward high functionality of various industrial equipment, electronic circuit boards now require excellent parts mountability and compatibility with high currents. Panasonic has developed a glass composite circuit board material (CEM-3 grade) that achieves the industry's lowest*1 coefficient of thermal expansion (CTE)  by using its unique manufacturing method and resin design technology, thereby contributing to the improvement of parts mounting reliability and compatibility with high currents for electronic circuit boards.
Automotive equipment (Instrument panels), power supply/power device module circuit boards, infrastructure equipment (Smart meters, antenna communication equipment), appliances (Air-conditioners, power conditioners), etc.
This new product will be exhibited at JPCA Show 2018, which will be held at Tokyo Big Sight from June 6 to 8, 2018.
