| PC104 stack | Card Slot System |
|---|---|
| Uses COTS connectors | Uses Nano & Micro D-SUB and Strip space qualified connectors |
| Random access to cards: impossible | Facilitates random access to cards during integration and testing |
| Shared functions – compromises: | Separated main functions: |
| – Geometric size of stack: large uncertainty | – Card guides provide precise geometry |
| – Increased structural load on cards and connector | – Connectors and cards: free from structural load |
| – Thermal management: cards in series, interdependent | – Thermal management of cards: parallelized, independent |
