Yanaichi Electronis is shipping a High-Heat-Resistant Flexible Printed Circuit Board YFLEX – Yamaichi Electronics’ Answer to Heat Challenges.

The YFLEX flexible printed circuit board from Yamaichi Electronics is now also available as a high-heat resistant version for extreme environments. This  FPC was developed to meet the requirements in areas such as automotive, semiconductor manufacturing and test and measurement technology.

The high-temperature resistant Flexible Printed Circuit YFLEX impresses with its improved insulating layer, which has increased adhesion thanks to the use of a special cover layer.

Even under extreme temperatures of up to 150°C, it retains its electrical properties for over 3,000 hours. The continuity resistance remains within a rate of change of ±10% and the insulation resistance is 500 MΩ or higher. This outstanding resistance ensures the reliable performance of the FPC even in the most adverse environments.

The PCB is extremely versatile, claims Yamaichi, and can be produced in both single-layer and double-layer configurations. The insulation substrate base can be selected from liquid crystal polymer (LCP) or polyimide (PI) in order to optimally adapt to different applications.

In addition, it has a reinforced GND design that is suitable not only for high-heat-resistant but also for noise-resistant FPC applications.
