Panasonic Commercializes High Heat Resistance Halogen-free Multi-layer Circuit Board Material for Automotive Use
2016/12/24

Panasonic’s "High Heat Resistance Halogen-free Multi-layer Circuit Board Material" will contribute to improving reliability of automotive ECU circuit boards, even when they are directly mounted on engines.

Osaka, Japan - Panasonic Corporation announced today that it has commercialized its High Heat Resistance Halogen-free Multi-layer Circuit Board Material [Product No. R-1566(S)] for automotive electronic control unit (ECU) circuit boards. The company will start mass production in April 2017. The product’s high heat resistance and excellent tracking resistance[1] will improve the reliability of ECU circuit boards in high-temperature environments.

The number of ECUs mounted per vehicle has been on the rise with advances in the electrification of automobiles. ECUs are often mounted in engine compartments to preserve passenger compartment space, and therefore require resistance to high temperatures. The heat generated by high-performance ECU components themselves also needs to be addressed. Furthermore, circuit board materials need to be increasingly resistant to high temperatures to cope with the larger currents and higher voltages carried by HEV and EV ECU circuits. In the past, improving heat and tracking resistances usually resulted in lower processability of circuit boards due to materials properties. To resolve this issue, Panasonic has commercialized its High Heat Resistance Halogen-free Multi-layer Circuit Board Material, which features high heat and tracking resistances as well as excellent circuit board processability by adopting its unique resin design and compounding technologies based on the quality developed for automotive products.
