🚀 When Do We Really Need Enclosure Boxes for PCBs in Satellite and Launch Vehicle Systems?

In the mechanical integration of On-Board Computers (OBCs) within satellites and launch vehicles, developers have multiple options:
👉 No enclosure box – PCB mounted directly on chassis platforms or rails
👉 Aluminum or
👉 Carbon fiber enclosure box

The choice depends on key design considerations such as accessibility, weight, vibration resilience, and cost.
As an OBC manufacturer, it’s essential to perform detailed mechanical analysis of our PCBs to determine the optimal placement of mounting holes—typically M3 size—and to deliver a tailored mechanical design for every single mission! We conduct vibration analysis for OBCs in design stage to identify critical stress points. This ensures the mechanical reliability of the OBCs in harsh environments, whether they are used without an enclosure or with aluminum or carbon fiber enclosures.
✔️ This approach helps prevent project delays and effectively reduces costs associated with testing and operations.
