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
The TG value of the board is high, there are many fillers, and the drilling needle wear is significant
High aperture ratio, high length to diameter ratio of drill needle, and easy breakage of drill needle
For the drilling difficulties of server PCB boards, our company designs drilling needles from the following perspectives
| Knife shape | Coating | Characteristic |
|---|---|---|
| UCK series | PCMR/Lubricating Coating | Good rigidity, able to cope with the problem of low CPK in drilling. |
