Fan out Rigid-Flex-Multilayer

The length of this board over all is not even 8 cm and the thickness is only 0.8 mm. The rigid area is completely free of adhesives to obtain a maximum of thermal cycle stability.

The 3 MIL conductor width, the photostructurable polyimide coverlay and the 50 µm milling tolerances are issues to be handled without special preliminary work at the production site of ANDUS.

In addition to the 4 meter flex-multilayer PCB, this project is also designed for a space application and proves again the manufacturing capabilities of ANDUS.
