Swissbit DRAM Modules – Ruggedized DIMMS

Designers of rugged platforms face a difficult decision when planning their memory layout. Either they use DRAM components directly soldered to the system board, the most rugged but also expensive and inflexible solution, or they take standard SODIMMs and try to ruggedize them by using straps or glue in order to fix them in their socket.
