EADSPCB is a circuit board specifically designed and manufactured for electronic devices in the aerospace industry. In the aerospace environment, there are extreme factors such as temperature, pressure, and radiation. Therefore, materials with high temperature resistance, high pressure bearing capacity, and radiation resistance are usually selected to ensure their reliability, stability, and performance under extreme environmental conditions. Common materials for aerospace circuit boards include polyimide (PI), polytetrafluoroethylene (PTFE), etc. These materials have good electrical properties, high temperature resistance, and chemical stability, which can meet the needs of spacecraft in extreme environments.

Aerospace specificIn order to ensure its working performance under harsh conditions such as high temperature and vibration, PCB resins usually have high TG values and hard fillers.

For drilling, the drilling difficulties of such boards include
