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) [1] 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.
Panasonic's new glass composite circuit board material has the following features:
The industry's lowest*1 coefficient of thermal expansion that improves the parts mounting reliability of electronic circuit boards
• Coefficient of thermal expansion 15 – 17 ppm/°C (α1) (Board thickness: 0.8 mm)
• Panasonic's conventional product*2: 20 – 23 ppm/°C (α1) (Board thickness: 0.8mm)
Excellent tracking resistance [2] compatible with the miniaturization of high-current circuit boards
• Comparative tracking index (CTI) ≥ 600 V
• Panasonic's conventional product*3: 250 V > CTI ≥ 175 V
Highly accurate board thickness that contributes to the stable operation of electronic circuit boards
• Board thickness accuracy: ±0.05 mm (Board thickness: 1.6 mm)
• Panasonic's conventional product*3: ±0.10 mm (Board thickness: 1.6 mm)
(Twice the accuracy)
Notes:
*1: As a glass composite circuit board material (CEM-3 grade) as of June 4, 2018 (Panasonic data)
*2: Panasonic's conventional product (General glass composite circuit board material, Panasonic product number: R-1786)
*3: Panasonic's conventional product (General glass epoxy circuit board material, Panasonic product number: R-1705)
