Astradyne has developed an innovative technology named FRET (Flexible, Reinforced Electronics with Textile), which reinforces Flex PCBs (flexible printed circuit boards) with textile materials.
The Flex PCB is widely adopted in the space sector. It is based on a polyamide flexible layer that allows electronics component integration on a flexible surface. A significant limitation of the Flex PCB is its fragility. Polyamide can be easily broken if subject to mechanical solicitations, and for this reason is not suitable for applications that requires high levels of reliability, such as mechanical in-space deployment.
