Satellite Applications and Flexible Printed Circuit Boards (FPCBs)
In satellite applications, flexible printed circuit boards (FPCBs) are preferred over rigid PCBs due to their numerous advantages, making them the ideal choice for space applications.
Key Considerations for FPCB Design in Space Applications
- Operating Temperature: The design of FPCBs for space applications should consider the internal environment of the spacecraft. Selecting materials with an operating temperature above 120°C is crucial for ensuring performance in space conditions.
- Gas Release Prevention: When FPCBs are used in high-pressure vacuum environments, trapped gas from the manufacturing process can be released, potentially causing issues. By employing heat to force the gas out through degassing, and using materials with good heat resistance, outgassing can be minimized.
- Impact Resistance: Satellites orbit the earth and may encounter collisions with other objects. To withstand these impacts, flexible PCBs must possess high bending capabilities. Flexibility and bendability are essential factors to consider when designing FPCBs for space applications.
